Question

well. The problem i’m facing is i have my own custom control and i do a query , get records and dynamically add html controls to the page based on the data.

Now there’s the problem of adding some dynamic javascript

I do this with the help of literal controls.

<asp:Literal runat="server" ID="latEventToolTipJqueryScripts"></asp:Literal>

This works like a charm

<script language="javascript" type="text/javascript">
// <![CDATA[
    Sys.Application.add_load(WireEvents_<%=this.ID%>); // fix wiring for .NET ajax updatepanel
    $(WireEvents_<%=this.ID%>); // handle page load wiring

    function WireEvents_<%=this.ID%>() {
        <asp:Literal runat="server" ID="latEventToolTipJqueryScripts"></asp:Literal>
    }

// ]]>
</script>

I add the literal text dynamically from code behind.

However, when placing the control in an updatepanel, the postbacks don’t update the script.

EDIT: The Sys.Application.add_load rewires the necessary functions just fine with the updatepanel. The problem is that the script that needs to be in place of the literal, doesn’t update when in an updatepanel.

I’ve tried the ClientScript.RegisterStartupScript but it has the same effect as with the literal control trick. Any help?

—————————SOLVED (tnx to Pranay Rana)———————————-

Got rid of the literal in the ascx side. as well as the Sys.Application.add_load

now it’s only in the code behind. The thing that was throwing me off was the JQuery thing.

this.strBuilderJS.Append( "<script language='javascript' type='text/javascript'>" +
                                "$(WireEvents_" + this.ID + ");" + 
                                "function WireEvents_" + this.ID + "(){"+
                                "    alert('stuff');");

this.strBuilderJS.Append(       "}</script>");

and then

ScriptManager.RegisterStartupScript(this, this.GetType(), "strBuilderJS", strBuilderJS.ToString(), false);

Make use of ScriptManager.RegisterStartupScript() to register your script…may resolve problem …
