Register CSS file in Sharepoint so that the web part stays themable - css

I need to register my css file from code behind. Initialy i used the following code:
CssRegistration.Register("myStyles.css", true);
The problem is, that the file is, like this, expected to be in a folder like 1033/styles within the layout folder. Now there is my problem: For each country (or language region) i need to copy my css into another xxyy/styles-folder. Until now every attempt to solve this situation failed.
What I tried so far
Setting a path:
CssRegistration.Register("/_layouts/myFolder/myStyles.css", true);
This works but if I try to change the theme within Sharepoint, the webpart is not changing anymore.
Using this way:
CssRegistration cssRegistration = new CssRegistration
{
After = "corev4.css",
Name = "/_layouts/MyFolder/myStyles.css",
EnableTheaming = true
};
Controls.Add(cssRegistration);
Same situation over here...
Does anyone know more?

I did like this several times and never had a problem.
First you have to map the Layouts folder in your visual studio project, then insert the CSS over there (but i guess you already did this)
Then you have to do this in your code behind:
CssLink cssLink = new CssLink();
cssLink.DefaultUrl="/_layouts/PROJECTNAME/styles/FILE.css";
if (!this.Page.Header.Controls.Contains(cssLink)) {
this.Page.Header.Controls.Add(cssLink);
}

Set background-url css property to a memory image in .net

Please read about my following situation. So we have a web application in .net. Because some customers wanted to pay for some custom layout, we first started to use themes. It was ok until there were more than 10. Because after that it was difficult to maintain and more of them wanted custom design, I had to design a solution so that the user could change only a few css attributes through a front-end page.
So when a user clicked a button a folder with its name and another css file was generated and he could change the attributes and save the new file. This file was dynamically loaded on the Page_Load on some basebage. This was ok, until more and more users payed for this and now we have tens of folders and expect hundreds. There is also the problem of rights, by default IIS doesn't have writing right to the application folder. Also the deployment process builds a new version by deleting the whole app folder and recreating one so we had to do a workaround and make a copy of this mega folder that holds the users css. And anyway, I don't like the idea of having hundreds of files not under source control.
And now, I have a new requierement. The users to be allowed to upload a custom image to replace one of our own. So i said it is time to move evrything to the database. For basic attributes I solved it.
I have a "mutant" aspx page:
<%# Page Language="C#" ContentType="text/css" %>
.labelText
{
color:<%= WebApplication1.UserProfile.LabelColor%>
}
So the UserProfile class gets it's data from a table.
And then in the page_load of the basepage
HtmlLink link = new HtmlLink();
link.Attributes.Add("type", "text/css");
link.Attributes.Add("rel", "stylesheet");
link.Attributes.Add("href", "~/Styles/Override.aspx");
this.Header.Controls.Add(link);
It works ok, the problem the images are used like this:
.divHeader
{
background: 15px 0 url("logo.gif")
}
That logo.gig will be uploaded by the user,but I would like to be saved in the database. However when reading it as a stream I can't do something like:
background: 15px 0 url(WebApplication1.UserProfile.Logo)
Is there any otehr way I can specify an object in a css class?If it isn't what is the best approach? I was thinking about keeping the image in the db and also as a file, something similar to what we have now.
I realize that if it were for an image control it would have been a lot easier, but this is the design now, and remaking it is a little bit troublesome
Thanks for reading this novel and for any oppinions on this.
I hope you're saving the mime-type value of every image that you save to database (mime type is reported by the request during upload). If you don't, you'll have to look up what a mime type would be based on image-file extension or its content format. You'll need this value when images are requested (from within CSS files).
Implement an HTTP handler (.ashx) specifically for these images (new file > generic handler > fill up ProcessRequest).
Then, replace url(logo.gif) in your css files with something like this:
url(/GetImage.ashx?user=1234&image=logo);
Obviously, you can have the filename and query to be whatever you like/need. Maybe you have user info in session, so you don't have to include user id there. Maybe you'll want to implement this handler only for logo images, and if you have user info in session, you can simply say (css):
url(GetLogo.ashx);
Then, within that ashx handler, write code to get the image from the database (or where ever it is), and stream it to the browser. Something like this:
byte[] imageData = ... // get this from db
MemoryStream ms = new MemoryStream(imageData); // System.IO namespace
Response.ContentType = "image/png"; // remember the mime-type?
ms.WriteTo(context.Response.OutputStream); // context is current HttpContext
Alternatively, you can inject the whole image into the CSS, by encoding it to base-64 format. Note that the size of css file will grow for the size of the image, and you're practically combining multiple downloads into 1, which may be a good or a bad thing.
Example below (google's logo); paste this in CSS (notice the size of that thing).
Besides CSS, the data in this example (data:image/png;base64,iVBORw0KGg ...) can be used as URL with IMG tags, or manipulated by JS.
.somediv
{
width:275px;
height:95px;

ASP.NET Theming Programmatically: Image Paths

We have a multilingual site, or culture-sensitive, and some of the static content now needs to be targeted; for this I'm using themes as it seems the easiest way to achieve what I want, but I can't for the life of me get the images to pick up.
I'm setting the theme in code-behind, and thought at first that maybe this was the issue, but on checking up it looks like I'm doing the right thing (setting on Pre-Init).
I expect to be able to reference images using relative paths where App_Themes/ThemeName/ is automatically resolved, such as:
<asp:Image runat="server" ImageUrl="images\image.jpg"/>
For whatever reason, however, the image isn't being pulled through at all.
This is the code we have in place for setting the theme (the only really relevant part, I'm sure, being the Theme = CurrentSite.CultureName, which is applied successfully):
Private Sub SetTheme()
Dim themesPath = Server.MapPath("~/App_Themes")
If Directory.Exists(themesPath) Then
Dim themePaths = Directory.GetDirectories(themesPath)
Dim themePathInfo As DirectoryInfo
For Each _path In themePaths
themePathInfo = New DirectoryInfo(_path)
If Not themePathInfo Is Nothing Then
If themePathInfo.Name = CurrentSite.CultureName Then
Theme = CurrentSite.CultureName
Exit For
End If
End If
Next
End If
End Sub
In the above code, CurrentSite.CultureName would be a language culture name (for example, en-gb, or nn-no) that does have an existing corresponding theme folder containing all required resources.
Pages do have EnableTheming set to True. Also, I have tried removing the theme-setting code and applying the theme in the page using Theme="en-gb" to no avail.
Is there anything immediately evident as to why the URLs aren't resolved?
Use a Skin file to do this. Change your Image tag to:
<asp:Image runat="server" SkinID="SomeImage/>
And in your App_Themes\MyTheme\ folder, add a new Skin file (MyTheme.skin) and add this:
<asp:Image runat="server" SkinID="SomeImage" ImageUrl="images\image.jpg"/>
This image skin now points to image.jpg within the App_Themes\MyTheme\ folder.
For dynamic images you can do this in your BasePage (assuming you have one):
public string ThemePath { get { return "~/App_Themes/" + this.Theme + "/"; } }
public string MapThemePath(string relativePath)
{
return string.Format("{0}{1}", this.ThemePath, relativePath);
}
But, since I can't see what you're actually doing, I can't say this is the recommended solution. In general your theme contains only things needed or layout and display. You're talking about dynamic images which, to me, doesn't sound like it belongs in a theme? Not sure, just a thought.

MVVM Light + Blend designer view error: Cannot find resource named 'Locator'.

The application runs fine but i could not see my design in the designer view.
It says Cannot find resource named 'Locator'. Obviously, i did not change anything in the code, i just did the data binding using the data binding dialog...
anyone facing the same problem?
There are two known occurrences where this can happen.
If you change to Blend before you built the application, the DLLs are not available yet and this error can be seen. Building the application solves the issue.
There is a bug in Expression Blend where, if you are placing a user control in another user control (or Window in WPF), and the inner user control uses a global resource, the global resource cannot be found. In that case you will get the error too.
Unfortunately I do not have a workaround for the second point, as it is a Blend bug. I hope we will see a resolution for that soon, but it seems to be still there in Blend 4.
What you can do is
Ignore the error when working on the outer user control. When you work on the inner user control, you should see the design time data fine (not very satisfying I know).
Use the d:DataContext to set the design time data context in Blend temporarily.
Hopefully this helps,

I've come up with a reasonably acceptable workaround to this problem since it doesn't appear to have been fixed in Blend 4:
In the constructor for your XAML UserControl just add the resources it needs, provided you're in design mode within Blend. This may be just the Locator, or also Styles and Converters as appropriate.
public partial class OrdersControl : UserControl
{
public OrdersControl()
{
// MUST do this BEFORE InitializeComponent()
if (DesignerProperties.GetIsInDesignMode(this))
{
if (AppDomain.CurrentDomain.BaseDirectory.Contains("Blend 4"))
{
// load styles resources
ResourceDictionary rd = new ResourceDictionary();
rd.Source = new Uri(System.IO.Path.Combine(Environment.CurrentDirectory, "Resources/Styles.xaml"), UriKind.Absolute);
Resources.MergedDictionaries.Add(rd);
// load any other resources this control needs such as Converters
Resources.Add("booleanNOTConverter", new BooleanNOTConverter());
}
}
// initialize component
this.InitializeComponent();
}
There may be some edge cases, but its working OK for me in the simple cases where before I'd get a big red error symbol. I'd LOVE to see suggestions on how to better solve this problem, but this at least allows me to animate user controls that otherwise are appearing as errors.
You could also extract out the creation of resources to App.xaml.cs:
internal static void CreateStaticResourcesForDesigner(Control element)
{
if (AppDomain.CurrentDomain.BaseDirectory.Contains("Blend 4"))
{
// load styles resources
ResourceDictionary rd = new ResourceDictionary();
rd.Source = new Uri(System.IO.Path.Combine(Environment.CurrentDirectory, "Resources/Styles.xaml"), UriKind.Absolute);
element.Resources.MergedDictionaries.Add(rd);
// load any other resources this control needs
element.Resources.Add("booleanNOTConverter", new BooleanNOTConverter());
}
}
and then in the control do this BEFORE InitializeComponent():
// create local resources
if (DesignerProperties.GetIsInDesignMode(this))
{
App.CreateStaticResourcesForDesigner(this);
}
Note: At some point in time this stopped working for me and I ended up hardcoding the path to the Styles.xaml because I got frustrated trying to figure out which directory I was in.
rd.Source = new Uri(#"R:\TFS-PROJECTS\ProjectWPF\Resources\Styles.xaml", UriKind.Absolute);
I'm sure I could find the right path with 5 minutes work, but try this if you're at your wits end like I was!
In MyUserControl.xaml, instead of:
DataContext="{Binding Main, Source={StaticResource Locator}
use:
d:DataContext="{Binding Main, Source={StaticResource Locator}
where "d" has been previously defined as:
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
The reason and workaround explained here
http://blogs.msdn.com/b/unnir/archive/2009/03/31/blend-wpf-and-resource-references.aspx
Look at (b) part of the post.
I had a similar problem with a user control resource.
I added this in my usercontrol xaml code:
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/GinaControls;component/Resources/GinaControlsColors.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
Where GinaControls is the namespace where the control class is declared and /Resources/GinaControlsColors.xaml is the project folder and xaml resource file name.
Hope this helps.
Just add this in your App.xaml.cs at the very beginning
here's my piece of code
[STATThread()]
static void main(){
App.Current.Resources.Add("Locator", new yournamespace.ViewModel.ViewModelLocator());
}
public App(){
main();
}
Make sure the Blend has opened the entire solution and NOT just the single project containing the views. I was right-clicking in Visual Studio and selecting Open In Expression Blend. To my surprize, Blend could not find the solution file, so it only opened the single project.
When I realized this, I launched Blend directly, pointed it to the solution file, and then Blend was able to find the ViewModelLocator in my view.

Why can't I get value fckeditor. done after their code example [Javascript]

I wonder why I can't get value from FCKEditor with this javascript? I work with asp.net so I know the controls get different names, mine is in a placeholder and in a usercontrol. How should I approach it to find the FCKEditor?
thx
function test()
{
var oEditor = FCKeditorAPI.GetInstance('FCKeditor1');
var pageValue = oEditor.GetHTML();
alert(pageValue);
}
This should work, but the problem is that using this approach you can not have this function in external JavaScript file. It has to be inline in your asp.net page.
function test()
{
var oEditor = FCKeditorAPI.GetInstance(<%= FCKeditor1.ClientID%>);
var pageValue = oEditor.GetHTML();
alert(pageValue);
}
FCKeditorAPI.GetInstance('<%=FCKeditor1.ClientID%>')
ASP.NET generates different IDs to the ones you use based on their position within the DOM. You should use the ClientID from within the client code to get at the actual ID, but without seeing the mark-up I can't tell for sure.
i tried this code an it work
FCKeditorAPI.GetInstance('ctl00_ContentPlaceHolder1_ctl00_FCKeditor1');
i tried
FCKeditorAPI.GetInstance('<%=FCKeditor1.ClientID%>')
thing that last wont work cause i got page - usercontrol - fckeditor
so the intellesence wont show the fckeditor. i would like to make it work with the last one
so i dont have to put the "ctl00_ContentPlaceHolder1_ctl00_FCKeditor1"

Setting Page Title from a SWF

Is it possible to set the title of a page when it's simply a loaded SWF?
This is how I would do it:
ExternalInterface.call("document.title = 'Hello World'");
Or more generalized:
function setPageTitle( newTitle : String ) : void {
var jsCode : String = "function( title ) { document.title = title; }";
ExternalInterface.call(jsCode, newTitle);
}
Sure. This should fix you up:
getURL('javascript:var x = (document.getElementsByTagName("head")[0].getElementsByTagName("title")[0].firstChild.nodeValue = "This is a test!");');
Just replace "This is a test!" with your new title.
I would think you would be able to do it. You would have to access the javascript DOM.
A couple links that may steer you down the correct path..
http://homepage.ntlworld.com/kayseycarvey/document2.html
http://www.permadi.com/tutorial/flashjscommand/
You could use SWFAddress, it has a setTitle method. Plus, you get the added benefit of beng able to modify the URL for deep-linking.
EDIT: This won't work if the SWF is loaded directly in the browser, only if it is embedded in HTML.
I came up with the same problem of setting up the title of my page. Madw hell lot of efforts from downloading aspFlash controls to those swfObject....
Finally my team lead came up the solution....
open the pop of one page and in that page use one IFrame and use the Iframe to load the swf file.
So there are 2 page outer one is our control so just set the title.. inner one is the Iframe which is just another page so load the swf file directly by setting the scr="file path"
