I used Facebook like button in ASP .Net my web site master page and when sharing page link in Facebook. I want to change the thumbnail attach with link to each pages, I get image url back end of my asp website and assign to variable and when I'm trying to bind it to front end as below it doesn't get actual value
<link rel="image_src" type="image/jpeg" href=" <% = ImgLink %>"/>
(ImgLink is dynamic variable I got from my back end of code ) at least it doesn't suggest in visual studio.
Try
<asp:PlaceHolder runat="server">
<link rel="image_src" type="image/jpeg" <%= "href='" + ImgLink + "'"%>/>
</asp:Placeholder>
Here is a detailed explanation why this is working.
LitFacebook.Text = "<a name=\"fb_share\" type=\"button\" share_url =\"http://kidstrail.inoday.co.in/\"></a>" +
"<script " +
"src=\"http://static.ak.fbcdn.net/connect.php/js/FB.Share\" " +
"type=\"text/javascript\"></script>";
On Design Page, Take a Literal control:
<div style="float:left; height:18px; margin-left:3px; overflow:hidden;"><asp:Literal ID="LitFacebook" runat="server" ></asp:Literal> </div>

I'm trying to use Adobe's new Aviary/Feather SDK with an existing aspx webpage.
Here is the HTML for the Feather integration.
you will notice that i had to add https://test.mywebsite.com before the <% imgEvent.imageUrl %> . Without the website url appended to the beginning the Feather would not work properly.
ASPX page
<div class="span12">
<div id='injection_site'></div>
<asp:Image ID="imgEvent" runat="server" />
<p><input type='image' src='http://images.aviary.com/images/edit-photo.png' value='Edit photo' onclick="return launchEditor('imgEvent', 'https://test.mywebsite.com<%= imgEvent.ImageUrl.ToString()%>');" /></p>
</div>
This will result in the following
HTML page
<div class="span12">
<div id='injection_site'></div>
<img id="imgEvent" src="/image/get/webfile/80a556a0-c251-4fc5-b6e2-9061d8f90f18" />
<p><input type='image' src='http://images.aviary.com/images/edit-photo.png' value='Edit photo' onclick="return launchEditor('imgEvent', 'https://test.mywebsite.com/image/get/webfile/80a556a0-c251-4fc5-b6e2-9061d8f90f18');" /></p>
</div>
The problem seems to be that once Feather is used and the image has been affected with the desired effects, the Html is updated like so
<img id="imgEvent" src="http://featherfiles.aviary.com/2014-10-27/1d6ab55fcc2ecaf5/f304c34d77bc446aa5fb6278dcbea5da.png">
This is because i assume the file is temporarily being stored on their website for the preview. How would i go about downloading this file using the ASPX code behind method?
If i do Me.imgEvent.ImageUrl it will give me the url that was associated to the img on page_load. (Me.imgEvent.imageUrl = "/image/get/webfile/80a556a0-c251-4fc5-b6e2-9061d8f90f18")
Is there a way to pass the new img src parameter to the code behind?
You can make an ajax call to your server with the new url as a parameter. For instance, using the jQuery library, and assuming you have an aspx page with a POST handler, you could do the following:
function onSave(id, url) {
$.post( "saveImage.aspx", { newUrl: url });
}
Writing html using Response.Write in asp.net it doesn't display the image. I check my image path code and simple put it in the page and it works fine. Why it doesn't display the image when writing using response.write code.
Following is my image path code
<img alt="" src="<%= VirtualPathUtility.ToAbsolute("~/Content/images/txt2.png")%>" border="0"/>
This is Response.write code
<% Response.Write(valueHelp); %>
ValueHelp is a string which contain the image code which i have mention above.
Any idea why it is not working?
Thanks in advance
<%= %> is to be used within the mark-up (i.e. the HTML part of your code) and not in the code-behind.
My guess (without seeing the code) is that you are actually sending <%= VirtualPathUtility.ToAbsolute("~/Content/images/txt2.png")%> to the browser as part of a static string.
So instead of it being picked up by the server and rendered into the correct path, it is simply being sent as part of the HTML to the browser (the browser not knowing what on earth it means, therefore it will not show the image you expect).
Try something like this when you are creating the valueHelp string
valueHelp = "<img alt='' src='" + VirtualPathUtility.ToAbsolute("~/Content/images/txt2.png") + "' border='0'/>";
Try this
<% Response.Write("<img alt='' src='" +
VirtualPathUtility.ToAbsolute("~/Content/images/txt2.png") +
"' border='0'/>" ); %>
i am trying to display a simple div with hyperlink that represents x
like this:
So, when my run my app i see the div but i dont see the x which is <a href tag
and here is my code:
<div class="success">×status message here...</div>
and when i looked at the source of the page this is what it renders:
<div id="ctl00_ctl00_ContentMain_ContentMain_employee_status" class="success" style="display:block;">status message here...</div>
and then i tried with <asp:hyperlink....
<div class="success" id="divStatus" visible="false" runat="server"><asp:HyperLink id="success" runat="server" CssClass="close" Text="×"></asp:HyperLink></div>
and i still dont see href tag, what is going on here and why i am not able to render the <a href or <asp:hyperlnk tag any clue?
i am writing InnerHtml divSuccess.InnerHtml ="status message here...
if thats the case that erasing its static contents then what is the
alternate?
If divStatus contains controls that you want to keep, then you can append HTML to it by using a Literal control and adding it to the controls collection, like:
var lit = new Literal();
lit.Text = "my text or <strong>html</strong>";
this.divStatus.Controls.Add(lit);
Alternatively, you could use another control inside divStatus and alter its inner HTML:
<div id="divStatus" runat="server">
<a id="lnk1">This is the link that we don't want to be removed.</a>
<asp:Literal runat="server" id="litStatusHtml" />
</div>
here is how i able to solved my question
divStatus.InnerHtml = "<a href='#' class='close'>×</a>" + "status message here...";
I have a page where I wish to render the following html (a small JS template)-
<script type="text/html" id="lightbox-template">
<div id="lightbox-background"></div>
<div id="lightbox"><%= content %><div class="bottom"></div></div>
</script>
However, the Asp.NET preprocessor is picking up on the "<%=" tag and trying to interpret it. I wish to escape this tag to allow it to be rendered, preferably from the template rather than the code behind. Is this possible?
I have managed to do this via a Literal control and setting it's text in the code behind.
I ideally wanted to keep it within the aspx page. This is the best solution I could find (from here), which creates splits the closing > into a separate string
<script type="text/html" id="lightbox-template">
<div id="lightbox-background"></div>
<div id="lightbox"><%= "<%= content %" + ">" %=><div class="bottom"></div></div>
</script>
Important bit: <%= "<%= content %" + ">" %=>
This goes into aspx
<div> <%= GetContentString() %> </div>
This goes into aspx.cs
protected String GetContentString()
{
return "this is a content";
}
I have a standard aspx page with which I need to add another standard HTML form into and have it submit to another location (external site), however whenever I press the submit button the page seems to do a post back rather than using the sub-forms action url.
A mock up of what the form relationships is below. Note in the real deployment the form will be part of a content area of a master page layout, so the form needs to submit independantly from the master page form.
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<form id="subscribe_form" method="post" action="https://someothersite.com" name="em_subscribe_form" >
<input type="text" id="field1" name="field1" />
<input id="submitsubform" type="submit" value="Submit" />
</form>
</div>
</form>
</body>
</html>
It's an interesting problem. Ideally you only want the 1 form tag on the page as other users have mentioned. Potentially you could post the data via javascript without having 2 form tags.
Example taken from here, modified for your needs. Not 100% sure if this will work for you but I think this is how you'll have to approach it.
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function postdata()
{
var fieldValue = document.getElementById("field1").value;
postwith("http://someothersite.com",{field1:fieldValue});
}
function postwith (to,p) {
var myForm = document.createElement("form");
myForm.method="post" ;
myForm.action = to ;
for (var k in p) {
var myInput = document.createElement("input") ;
myInput.setAttribute("name", k) ;
myInput.setAttribute("value", p[k]);
myForm.appendChild(myInput) ;
}
document.body.appendChild(myForm) ;
myForm.submit() ;
document.body.removeChild(myForm) ;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<div>
<input type="text" id="field1" name="field1" />
<asp:Button ID="btnSubmitSubscribe" runat="server" Text="Submit" OnClientClick="postdata(); return false;" />
</div>
</div>
</form>
</body>
</html>
If javascript is not a viable option - you can use .Net's HttpWebRequest object to create the post call in code behind. Would look something like this in the code behind (assuming your text field is an asp textbox:
private void OnSubscribeClick(object sender, System.EventArgs e)
{
string field1 = Field1.Text;
ASCIIEncoding encoding=new ASCIIEncoding();
string postData="field1="+field1 ;
byte[] data = encoding.GetBytes(postData);
// Prepare web request...
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create("http://someotherwebsite/");
myRequest.Method = "POST";
myRequest.ContentType="application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream=myRequest.GetRequestStream();
// Send the data.
newStream.Write(data,0,data.Length);
newStream.Close();
}
If you add an ASP.NET button to the form, and set its PostBackUrl property to the external site, then all the form data will be posted to that URL.
There is a very nice tricky solution for this problem.
You can insert a </form> tag before your <form> to close the asp.net form which causes the problem. Do not forget to add a <form> tag after your html form. It may cause the editor to give you an exception, but do not worry, it will work.
Nested forms are not possible in HTML according to the W3C. You can achieve your intended result using JavaScript or with jQuery as explained by Peter on a blog called My Thoughts.
In my experience, Appetere Web Solutions has the best solution. Simple and elegant...and it's not a hack. Use the PostBackUrl.
I just tried it and everything works as expected. I didn't want to use Javascript because I didn't want to include it in my Master Page for every page that uses it.
I had the same situation as Ross - except that my input types were all of the "hidden" varitey.
Cowgod's answer got me thinking about nested forms within my .aspx page. I ended up "un-nesting" my 2nd form OUT of the main .aspx form ( ) and placed it (along with my js script tags) just under the body tag - but before the main .aspx form tag.
Suddenly, everything was submitting as it was supposed to. Is this a hack?
ASP.NET allows you to have multiple forms on one page, but only one can be runat=server. However I don't think you can nest forms at all.
You might have to make a new master page, one without a form tag on it so the form will work on that one page only. This is not a good solution, unless you can place the form outside the master pages' form, and use javascript to submit the second form, but that's hardly better. There really is no good solution for what you are trying to achieve, and if so I'd like to hear it. I don't think you can do a POST call from a code-behind, can you? I'm sure there's some way. But that's probably the only solution: from code.
