Assign Different Client Events for Different Controls
In order to assign different client-events to different AJAX-enabled controls, you can use the approach shown in Example 1 .
Example 1: You can determine the target control of the AJAX request using the client-side events of the RadAjaxManager.
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="Button1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="Label1" />
</UpdatedControls>
</telerik:AjaxSetting>
<telerik:AjaxSetting AjaxControlID="DropDownList1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="Label1" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
<ClientEvents OnRequestStart="Start" OnResponseEnd="End" />
</telerik:RadAjaxManager>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
<asp:ListItem>111</asp:ListItem>
<asp:ListItem>222</asp:ListItem>
</asp:DropDownList>
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
function Start(sender, arguments) {
if (arguments.EventTarget == "<%= Button1.UniqueID %>") {
alert("StartButton");
}
if (arguments.EventTarget == "<%= DropDownList1.UniqueID %>") {
alert("StartDropdown");
}
}
function End(sender, arguments) {
if (arguments.EventTarget == "<%= Button1.UniqueID %>") {
alert("EndButton");
} if (arguments.EventTarget == "<%= DropDownList1.UniqueID %>") {
alert("EndDropdown");
}
}
</script>
</telerik:RadCodeBlock>
This way the DropDownList and the Button will have different client-events although they are using the same RadAjaxManager or RadAjaxPanel .
