i am using liferay-ui:search-container-column-button inside liferay container the button should point to another jsp with take parameter from the current selected row.
<liferay-ui:search-container emptyResultsMessage="There are no organizations available">
<liferay-ui:search-container-results
results="<%=OrganizationLocalServiceUtil.getOrganizationAll() %>"
total="<%=OrganizationLocalServiceUtil.getOrganizationsCount() %>">
</liferay-ui:search-container-results>
<liferay-ui:search-container-row
className ="fff.sem.service.model.Organization"
keyProperty="organizationId"
modelVar="organization"
escapedModel="<%=true %>"
>
<liferay-ui:search-container-column-text
name="Organization short name"
value="<%= organization.getOrganizationShortName() %>">
</liferay-ui:search-container-column-text>
<liferay-ui:search-container-column-text
name="Organization full name"
value="<%= organization.getOrganizationFullName() %>">
</liferay-ui:search-container-column-text>
<liferay-ui:search-container-column-button href="<%=addOrganization1URL %>"></liferay-ui:search-container-column-button>
<liferay-ui:search-container-column-jsp
align="right"
path="/html/sem/organization_actions.jsp"
/>
</liferay-ui:search-container-row>
As you noticed in the code I used search-container-column-jsp to add edit and delete feature for the row. I use a column with search-container-column-button so that each button of that column point to another form, but the search-container-column-button wont react on clicking. What is going on?
Recent Liferay forum posts indicate a potential issue with the taglib:
search-container-column-button does not work
Issue in calling an action from liferay search-container-column-button tag
grep of the Liferay source code nor a github search return a single instance where the taglib is used.
My attempts to use the <liferay-ui:search-container-column-button to properly call any type (action, render, resource) URL were not successful. In examining the source closer, I believe the generic dump of the href attribute value into the onclick attribute is the problem.
In comparing the html generated by a <aui:button> to that of the search-container-column-button the onclick attribute is missing location.href=
I would recommend using a liferay-ui:search-container-column-jsp as you have done for the other actions, but instead of an icon-menu use a <aui:button> if you want the field to be a button.
Including the missing info:
<%
final String hrefFix = "location.href='" + addOrganization1URL .toString()+"'";
%>
<liferay-ui:search-container-column-button href="<%=hrefFix%>"/>
does provide a working solution, however, if this is indeed a bug and is fixed in a future patch, this workaround would then become a bug.

I have a web page where I dynamically generate lots of elements from code behind and inject them into the page, as such:
input type="file" style="width:480px;" id="fileUploadLogo345">
I also have buttons for submitting, like this:
input id="Submit1" type="submit" value="Substituir Logo" onclick="return jsSubmitLogo(345);">
(The javascript function always returns true...)
No matter what I try, I am unable to get any of the uploaded files from code behind.
I tried adding enctype="multipart/form-data" to the form, I tried adding runat="server" to the file upload controls, I have no idea what else I could try. No matter what I do, in code behind Request.Files.Count equals zero.
Any idea what I could be doing wrong?
If it makes any difference, I am using a master page...
Thanks
You are using "id" attributes in your html... you should instead use "name" attributes, and everything will show up fine in code behind.
Situation: I have been creating webpages in HTML5/CSS3 & Javascript using Sublime 2 text editor for a year, however a college course now requires me to use Asp.Net and Visual Studio 2010. I do not use the designer because I am proficient at doing things by hand, however I find that writing asp: inside every element is time consuming and causes syntax errors when applied to some HTML 5 tags and not others.
Example HTML 5: <button id="btn" type="submit" value="Button"/>
Example Asp.net: <asp:Button ID="Button1" runat="server" Text="Button" />
Question: Can the asp: portion be omitted without effecting anything or is it required for IIS or the C# back-end functionality? What about runat="server" can that be omitted?
Google has come up dry regarding my inquiry, so any help is appreciated.
you simply cannot remove either of the two
but hear me out why, because I have a feeling you are not familiar with ASP and therefor are mistaking the meaning of the asp: and the runat="server" syntax.
first: runat="server"
this property on an element, tells the the compiler that this is actually a server side control
so a <button/> is not the same as an <button runat="server"/>
the first one is pure html, while the second one is a control, which can be bound to on the server side. .Net will give it a clientID (not to be mistaken by the ID you have to give it yourself).
second: asp:
this is a prefix, on certain elements, that tells the compiler these are ASP controls (the default controls given by the ASP.net framework). These include Buttons, TextBoxes, DropDownLists, ...
do not mistake 1 of these with a html element.
an <asp:Button id="myAspButton" runat="server"/>
is not the same as a <button id="myHtmlButton"/>
the first, is a server side control, which can be bound to (see it's runat="server" attribute), and this control renders to the browser as a <input type="submit"/> for example.
you could alter the rendering of the asp.net button class to make it return something entirely differnt if you wish.
and you are also not limited to using asp.net classes.
you can create your own controls, and put them in a custom created library
you could give those your own prefix.
if I created such a custom control, I could register a prefix for it in the web.config file,
and thus I could create a custom button extending from the original one (but with a default label in front...
<myc:CustomButton ID="myButton" Text="myButton" Label="myLabel" runat="server"/>
which could render into:
<label>myLabel</label>
<button ID="*******">myButton</button>
the asterisks are symbolizing the Unique ID it will get from the .net framework
if you want to know more on custom controls, or extending default controls
here is a step by step explanation to create custom controls, or extend from a TextBox control.
it also shows how you add a custom prefix for your controls (in the this case 'cc')
you can find more info here
The runat="server" part is required to tell .NET that it will have to render a button there (which will contain .NET specific ID for processing upon POST). Not too familiar with web forms (I started with MVC), but I would assume that the asp: part is to help distinguish between server controls and standard HTML markup.
Why not try removing it and if it breaks something, then you know it's needed. For instance if the button doesn't show up after removing it, then obviously the .NET markup parser needs it to be there in order to know that it is a place holder for a server control.
I'd like to be able to turn rows of an html table into links to controllers.
I figured something like
<td onclick="<%:Html.ActionLink("", "Index", new {id=item.user_id}) %>">
I'm using MVC 2
Thanks.
<td onclick="window.location='<%:Url.Action("Index", new {id=item.user_id}) %>'">
The onclick attribute accepts some javascript code to execute. If you simply give it a URL, javascript doesn't know what to do with that.
In the snippet above, you're setting the window.location property to the desired URL. This causes the browser to go there.
EDIT: I also just realized that you were using the Html.ActionLink() method which actually generates an tag in your code. You'd be better off using the Url.Action() method, which actually generates a URL.
As I understand it, the <input type=email> element in HTML5 will render as a simple text field in browsers that do not support the tag. On other browsers it will render properly, like on the iPhone it will bring up the e-mail keyboard layout.
I’d like to use this in a project but my input fields are <asp:TextBox> controls. How can I use the HTML5 element but still access its data server-side like the rest of my fields?
There is an update for .NET framework 4 which allows you to specify the type attribute
http://support.microsoft.com/kb/2468871.
See feature 3 way down the page
Feature 3
New syntax lets you define a
TextBox control that is HTML5
compatible. For example, the following
code defines a TextBox control that is
HTML5 compatible:
<asp:TextBox runat="server" type="some-HTML5-type" />
you can try adding the attributes manually, like:
TextBox1.Attributes["type"] = "email";
TextBox1.Attributes["type"] = "url";
TextBox1.Attributes["type"] = "number";
Sorry I'm a bit late to the party, though I think that others can benefit from what I did. I have a page which is HTML 5 though we still have .NET 3.5. We wanted to keep the .NET element, though have the type change to email. I've tried several methods (including Milox above) to no avail, though the one which worked for me was the following: I added a JavaScript property to the element itself inline (when I put it in a script tag it wouldn't pick up for some reason...)
Here is what your tag would look like if you use my changes:
<asp:TextBox runat="server" type="email" onfocus="this.type='email'"/>
Eli
Whether or not it is accessible as a server control, you should be able to access the HttpRequest.Form collection and retrieve the value. No matter what the browser does with the tag, it has to submit a string to the server.
in your .aspx file add
<input type="text" required autofocus placeholder="Email Address"
class="txt-input txt-input-username" ID="myTextBox" runat="server"/>
in your Code Behind .cs
myTextBox.Attributes["type"] = "email";
This Worked For Me
You need to create your own custom control and override the Render routines. Feel free to use either the source code or DLLs
After trying to understand why client code is not rendered in a page (injected by user control) I found this link, it turns out you must have a form tag for it to work (Page.RegisterClientScriptBlock did declare this but ClientScriptManager.RegisterClientScriptBlock which I use does not say anything regarding this).
I am using Visual studio 2005.
Does anyone know if this has been solved?
Edit:
To clarify, I want my control to add javascript code to the head section of the page without having to use the
<form runat="server"
I have tried adding it using:
HtmlGenericControl x = new HtmlGenericControl("script");
x.InnerText = "alert('123');";
Page.Header.Controls.Add(x);
But this did not work for me.
As far as I know this functions the same in current versions, you can test it very simply though.
Update
per discussion in the comments, the only "workaround" that I could think of would be for your to manually insert the script into the "head" section of the page on your own, using a runat="server" declaration on the Head element.
Got it!
My mistake was not doing it in the OnPreRender method (I used the Render method).
Now all that is needed is - like Mitchel Sellers wrote, set the header to runat server and than add to it's controls:
HtmlGenericControl x = new HtmlGenericControl("script");
x.InnerText = GetScriptSection();
Page.Header.Controls.Add(x);
Thanks for pointing me to the right direction!
The MSDN Page for registerclientscriptblock here says:
The client-side script is emitted just
after the opening tag of the Page
object's <form runat= server> element.
The script block is emitted as the
object that renders the output is
defined, so you must include both tags
of the <script> element.
If you do not want to include a form, than you will basically need to build your own implementation of it.
Minor clarification for anyone seeing this:
The form tag must have the runat="server" attribute set, e.g.
<form id="theform" runat="server">
Just placing a regular HTML form tag in the page will not help.
