Hello,
       I have a situation where i have to call radconfirm on clicking a server side asp button. Based on the confirm output i have to decide whether to copy or don't copy. By reading several forums i have seen something like this shown below :
'
function ValidateFn() {
    radconfirm("sure?", callbackFn);
    return false;
}
function callbackFn(arg) {
    //if the validation passes - 'simulate' the button's click
    if (arg) {
        __doPostBack("<%= CopyButton.ClientID %>", "");
    }
}

<asp:Button OnClientClick="ValidateFn(); return false;" >

This works fine with popup and the page gets reloaded completely again as we do a postback. But i have a ajax stuff where i need to avoid this postback

my code snippet is given below

.aspx

<asp:ScriptManager ID="ScriptManager1" runat="server" />
        <telerik:RadAjaxPanel runat="server" ID="AjaxPanel" LoadingPanelID="AjaxLoadingPanel">
                <telerik:RadSplitter ID="SplitPane" runat="server" height="400px" Width="600px" Skin="Vista">
                    <telerik:RadPane id="TreePane" runat="server" height="400px" Width="300px" BackColor = "White">
                        <telerik:RadTreeView runat="server" id="TreeView1" Skin="Vista"
                                OnNodeExpand="TreeView1_NodeExpand" CheckBoxes = "true"
                                 LoadingMessage = "loading..."></telerik:RadTreeView>
                    </telerik:RadPane>

                    <telerik:RadPane ID="buttonpane" runat="server" height="400px" width="310px" >
     <asp:Button ID="CopyButton" runat="server" Text="Copy" OnClick="CopyButton_Clicked"/>
    .....more buttons
             </telerik:radPane>
</telerik:RadSplitter>
<div>
                <asp:Label CssClass="WarningLabel" id="StatusLabel" runat="server"></asp:Label>
            </div>
        </telerik:RadAjaxPanel>

<telerik:RadAjaxManager ID="RadAjaxMgr" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="CopyButton">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="CopyButton" />
                        <telerik:AjaxUpdatedControl ControlID="StatusLabel" />
                        <telerik:AjaxUpdatedControl ControlID="AjaxPanel" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
<telerik:RadWindowManager ID="RadWindowMgr" runat="server" Skin="Vista"></telerik:RadWindowManager>

.cs

protected void CopyButton_Clicked(object sender, EventArgs e)
{
            if (CmsTreeView.CheckedNodes.Count <= 0)
            {
                // To show popup later
                string scriptstring = "radalert('select a destination to copy', 330, 210);";
                ScriptManager.RegisterStartupScript(this, this.GetType(), "radalert", scriptstring, true);
                //StatusLabel.Text = "select a destination to copy";
                return;
            }
     else
            {
                // proceed with copy functionality logic
            }
}

On button click i need the radconfirm popup and when the users selects ok then it shud come here and check the nodes count and rest will go as usual. If i used the _postback the entire page loads which i don't want. So how to handle this scenario. Please let me know.
