Hi...

I'm trying to dynamically register some client script in a user control Page_Load method... This user control is triggered by a RadGrid through the EditMode...

AJAX SETTINGS :

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        
                  <AjaxSettings > 
        
                      <telerik:AjaxSetting AjaxControlID="RadGrid1" > 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadGrid1"/>  
        
                           </UpdatedControls> 
        
                          </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager>

GRID :

    
             <telerik:RadGrid ID="RadGrid1" runat="server">  
        
                    <MasterTableView Name="masterView" GridLines="None" EditMode="PopUp" CommandItemDisplay="Top">  
        
                        <CommandItemSettings AddNewRecordText="Add new entry" RefreshText="Refresh" /> 
        
                        <EditFormSettings UserControlName="Control1.ascx" EditFormType="WebUserControl">  
        
                        </EditFormSettings> 
        
                    </MasterTableView> 
        
                </telerik:RadGrid>

USER CONTROL UI

    
            <%@ Control Language="vb" AutoEventWireup="false" CodeBehind="Control1.ascx.vb" Inherits="TestClientScriptRegister.Control1" %> 
        
            <asp:Button ID="Button1" runat="server" Text="Button" />

USER CONTROL SERVER SIDE CODE

    
             Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                Me.Page.ClientScript.RegisterClientScriptBlock(GetType(String), "Test", Me.GetScript(), True)  
        
                Me.Button1.Attributes("OnClick") = "Test()" 
        
              End Sub 
        
              Private Function GetScript() As String 
        
                Dim sb As New System.Text.StringBuilder()  
        
                sb.Append("function Test() {")  
        
                sb.Append("alert('what?');")  
        
                sb.Append("}")  
        
                Return sb.ToString()  
        
              End Function

Quite basic stuff... I know that there's some ways to achieve this without any dynamic script registering but for some reasons, I need to do it that way...
I tried a bunch of stuff without any success...
- EnablePageHeadUpdate = "true" in the AjaxManager
- RadScriptManager.RegisterClientScriptBlock
- Page.ClientScript.RegisterClientScriptBlock
- RadAjaxManager.GetCurrent(Page).ResponseScripts

Some remarks...
- Works well when using a radwindow that calls a page containing the user control.
- Works well when I remove the ajaxsettings that update the RadGrid in the RadAjaxManager.

Am I missing something? Maybe I'm not using the grid edit mode the right way... Is there a way to achieve this?

Thanks for your help : )

Still not working...

ResponseScripts works fine to register scripts that occurs right away. I need to register a javascript function that will get called later...

I tried with the panel and the place holder...still, no luck...I guess I'm missing something...

Let me explain why I need to dynamically register a client function. I have a user control that contains a bunch of asp:control within it. I need to have a client event raised when I click on a button that will disable some other controls. Now this user control is used multiple times within a single page (or within a user control that gets called by the grid edit form). This leads us to the main problem : My javascript function appears x times (x = number of instance of my user control) within the page. The only way I found to fix this is to dynamically register my javascript function in the server OnLoad event, to give it a unique name.

    
            sb.Append("<script type='text/javascript'>")  
        
            sb.Append("function MyFunction" + Me.UniqueID + "() {")

Then assign OnClick attribute of my button

    
            Me.myButton.Attributes.Add("OnClick", "MyFunction" + Me.UniqueID + "()")

I know it's asp.net stuff here more than telerik stuff, but I felt like I needed to explain exactly why I'm facing this issue.

Thanks for your support...

Ok, I've found a way to bypass this situation....

All I need is to have my javascript functions directly in the page and those functions would receive the ctrlId in parameters...

    
            function DisableForSelection(ctrl1, ctrl2) {  
        
             var radctrl= $find(ctrl1);  
        
             radctrl.disable();  
        
            }

Still I think this is a workaround, and I do believe that we should be able to register some javascript function dynamically from the load of a user control that gets called by the edit form of a radgrid...

Thanks
