            {
                string url = "window.open('AgendaPopup.aspx?IDOwner=" + IDOwner.ToString() + "','Dettaglio','width=500,height=500, menubar=no, scrollbars=yes, resizable=yes');";
                this.Page.ClientScript.RegisterStartupScript(this.GetType(),"openPopup", url,true) ;

I obtain this error

Sys.Web.Forms.PageRequestManagerParserErrorException: The message receviced from the server could not be parsed.
Common causes for this error are when the responses is modificed by calls to Response.Write(), response filters, HttpModules or server trace is enabled.

Details: Error parsing near '<script type='text/j'

Note: I use ajax toolkit in this page (included by a master page)

Thanks

Is the pop up blocker blocking your inital code? When you view the source code of the page in the browser are you seeing your JavaScript code?

 Eric

I dont' see the popup blocker message

 in the source code I can't see the JS

 I've searched the text "AgendaPopup" but I can't find reference

in the DDL code I see this:

         <select name="ctl00$Content$ucAnagrafica$ddl_NV_Cliente_RichiestaContattoCommerciale" onchange="javascript:setTimeout('__doPostBack(\'ctl00$Content$ucAnagrafica$ddl_NV_Cliente_RichiestaContattoCommerciale\',\'\')', 0)" id="ctl00_Content_ucAnagrafica_ddl_NV_Cliente_RichiestaContattoCommerciale" class="Text11">
                <option selected="selected" value=""></option>
                <option value="Si">Si</option>
                <option value="Richiamare">Richiamare</option>
                <option value="NN">Non interessato</option>

            </select

 

Nobody Can Help me??? :-((((( 

jsharratt: NEVER use Response.Write to output JavaScript as it places it before the page tags.

nixor: What error do you get as your code worked for me.

??? what do you mean?

I mean that the code worked for me. What are we doing different?

This is what I did with no problems:

aspx file:

<asp:DropDownList id="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
 <asp:listitem value="">Select one</asp:listitem>
 <asp:listitem value="Si">Si</asp:listitem>
 <asp:listitem value="Richiamare">Richiamare</asp:listitem>
 <asp:listitem value="NN">Non interessato</asp:listitem>
</asp:DropDownList>

aspx.cs file:

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
 if ( DropDownList1.SelectedValue == "Richiamare" )
 {
  int IDOwner = 123;
  ClientScriptManager clientScriptManager = Page.ClientScript;

  string javaScript =
   "window.open('AgendaPopup.aspx?IDOwner=" + IDOwner.ToString() + "','Dettaglio','width=500,height=500, menubar=no, scrollbars=yes, resizable=yes');";

  javaScript = "<script type=text/javascript>" + javaScript + "</script>";

  clientScriptManager.RegisterStartupScript(this.GetType(), "openPopup", javaScript) ;
 }
}

Of course, if you are using AJAX (I don't see why if you're setting AutoPostBack on the control) you would need to replace the ClientScriptManager object with a ScriptManager object.
