Question

The Master page got a ScriptManager.

Then i got a Control with a ScriptManagerProxy and an UpdatePanel.

Inside the UpdatePanel there I dynamically add a Control (also containing a ScriptManagerProxy) and from that control I need to run some JavaScript code.

DynamicControl.ascx:

<script type="text/javascript">
    function doSomething() {
        alert(1);
    }
</script>

DynamicControl.ascx.cs:

public void Page_Load(object sender, EventArgs e)
{
...
ScriptManager.RegisterStartupScript(
this.Page, this.GetType(), "scriptID",
"<script type='text/javascript'>doSomething();</script>", false);

My problem is that the function “doSomething()” is never called and i dont know why. :S
Edit: It is called but not directly when i add the control.

If I do code like this, there will be an alertwindow:

"<script type='text/javascript'>alert(1);</script>"

Ok I think i need to add some more information:

The control is dynamical added inside a jQuery Dialog. And I found out that the javacode is first executed after i close and then open the dialog. Some kind of event is triggered so that the code is executed there i think. Is it possible to force this event? so the scripts are executet directly when the control is added ?

placeHolder.Controls.Add(dynamicReportControl);

This c# code doesn’t execute the javascript tag immediately ?

Answer 1

Please try something like this

ScriptManager.RegisterStartupScript(
this.UpdatePanel1, this.UpdatePanel1.GetType(), "scriptID",
"<script type='text/javascript'>doSomething();</script>", false);

Where UpdatePanel1 is your UpdatePanel
