Re: Javascript onresize in an ASP.Net web page

30-Jan-09 15:26

I was going to say, something else must have been changed. The validation ( not very helpfully ) will complain about all sorts of markup that is valid on the client, but is not part of ASP.NET. Add an 'onblur' to a control, and you'll see this in action.

Well, I decided to go a different way (eliminating the javascript part). I have it displaying correctly in FireFox and Opera, but IE6 is being... ummmm.... problematic. I posted a question in the Web Development forum (since it has now become a CSS question).

You may have code that is stuck in an infinite loop. Use the debugger to step through your code.

I have a folder with files residing on the server not in the virtual directory. I have the TreeView Node pointing to one of these files. (C:\....\XXX.pdf) But when I click the link the pdf does not open. It is suppose to open in an IFRAME on the same window. Any Ideas?

Call a server function from javascript

Create one page that renders the files. Pass the file name in querystring. Put that page in your frame. Update your treeview.

How can I force a postback and call a codebehind function from javascript?
I want to do something like this:

aspx-file

<script type="text/javascript">
function OnRowSelecting(sender, args)   
{
    ServerFunc();
}
</script>

Codebehind c# file

private void ServerFunc()
{
    //… 
}

How I usually do this which may not be the best method. Drag a button on your form. Double Click it to get your server side code method. In the pageload hide the button from the user by adding the following:

<br />
   this.Button1.Style.Add("display", "none");<br />

Put your code server side in the button click's event. Then Add the following javascript to your page.

<br />
    function CallServerMethod() {<br />
             var Button1 = document.getElementById("<%=Button1.ClientID %>");<br />
             Button1.click();<br />
            }<br />

Now you can use the javascript "CallServerMethod()"

I dunno why someone gave this less than 5, it's the only real way to do it.

It works perfect for me.

About AJAX I luckily easily find a solution using our telerik-framework to avoid the whole page to refresh.

That's funny that you mentioned Telerik. I came up with that solution in order to search the radcombobox. I posted the code Telerik's website.

document.forms[0].submit() isn't this a simplier way ?

Not if he wants to call a specific event, no.

You realise that there's no way to do this without making an AJAX call ( which requires it's own set of work ) or refreshing the entire page ?

Hmm..What did you expect is there any thing music will playing around? Laugh | :laugh:

Ohh.. I was joking, What happened after that? Is there any data on your data set? Try to use break point and Debug you code. Check the Dataset has any data or not?
