Thanks Dimo

The problem I have is more to do with Ajax so the demo in the link is fine but...the response still updates the CheckboxList it is ijust that it has been altered.

I would like to exclude CheckboxList from the list of updated controls according to the button pressed so:

|242|updatePanel|ListBox1Panel|<select size="4" name="ListBox1" id="ListBox1" style="height:191px

;width:34px;z-index: 102; left: 204px; position: absolute; top: 87px">

	<option value="1">1</option>

	<option value="2">2</option>

	<option value="3">3</option>

</select>

is returned when New is pressed rather than including

402|updatePanel|CheckBoxList1Panel|<table id="CheckBoxList1" border="0" style="height:51px;width:26px

;z-index: 101; left: 251px; position: absolute; top: 91px">

	<tr>

		<td><input id="CheckBoxList1_0" type="checkbox" name="CheckBoxList1$0" /><label for="CheckBoxList1_0"

>1</label></td>

	</tr><tr>

		<td><input id="CheckBoxList1_1" type="checkbox" name="CheckBoxList1$1" /><label for="CheckBoxList1_1"

>2</label></td>

	</tr>

</table>

the CheckBoxList as well

Apologies for not making myself clear before.

Cheers

Apologies for not being clear Dimo.

I have a toolbar with two buttons on it. Button1 and Button2

Button1 is going to affect quite a large part of the page , panel1.

Button2 is going to affect only a small part of the page, panel2

the toolbar is the initiating control in the Ajax request
with panel1 and panel2 in the controls to update list

So as it stands at the moment although clicking Button2 causes panel2 to be changed panel1 and panel2 must come back in response to the Ajax request initiated by the toolbar. I only want to get panel2 back in the response.

This means I am gettting a lot more back then I need.

So what I would like is to say Button2 initiated this request I can update the contents of panel2 and in the repsonse only return panel2

Does that make more sense. I have a bit of cold.

Thanks

Hello Martin,

In order to achieve what you want, you need to set two different controls as AJAX request initiators for the two panels. So neither RadToolBar, nor RadAjaxManager are suitable for this purpose.

I am offering you the following approach - use two hidden asp:Buttons as AJAX initiators for the two asp:Panels. The buttons will be clicked programmatically in the RadToolBar buttons' client-side click event handlers. Here is an example:

    
            <%@ Page Language="C#" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <script runat="server"> 
        
                protected void Button1_Click(object sender, EventArgs e) 
        
                { 
        
                    ThreadWait(); 
        
                    Literal1.Text = DateTime.Now.ToLongTimeString(); 
        
                } 
        
                protected void Button2_Click(object sender, EventArgs e) 
        
                { 
        
                    ThreadWait(); 
        
                    Literal2.Text = DateTime.Now.ToLongTimeString(); 
        
                } 
        
                protected void ThreadWait() 
        
                { 
        
                    System.Threading.Thread.Sleep(2000); 
        
                }
