ItemClick Event Does Not Fire

Q: Why does my event does not fire?

A: There are two reasons for not getting the OnItemClick server-side event fired:

  • You have not subscribed to the OnItemClick event. Here is the correct subscription:
<telerik:RadMenu RenderMode="Lightweight" ID="RadMenu1" runat="server" OnItemClick="RadMenu1_ItemClick">
protected void RadMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)   
{       
    Response.Write("You clicked: " + e.Item.Text);   
}               
  • You have set the NavigateUrl property of the menu item.
<telerik:RadMenu RenderMode="Lightweight" ID="RadMenu1" runat="server" OnItemClick="RadMenu1_ItemClick">
    <items>                
        <telerik:RadMenuItem runat="server"  Text="This item will not fire ItemClick event" NavigateUrl="myPage.aspx">
    </items>                
</telerik:RadMenuItem>

This effectively disables PostBacks (OnItemClick event) because the item navigate to the particular URL rather than posting back. One of the possible solutions is to subscribe to the ItemDataBound / ItemCreated event and set the NavigateUrl property to an empty string. You should, however, store the NavigateUrl property somewhere (e.g. in the Value or Attributes[] properties) so you can use it later to navigate after handling ItemClick events. Here is a simple code snippet:

protected void RadMenu1_ItemDataBound(object sender, RadMenuEventArgs e)      
{          
    e.Item.Attributes["NavigateUrl"] = e.Item.NavigateUrl;          
    e.Item.NavigateUrl = "";      
}           

protected void RadMenu1_ItemClick(object sender, RadMenuEventArgs e)
{          
    //Custom code here                     
    //Navigate          
    Response.Redirect(e.Item.Attributes["NavigateUrl"].ToString());      
}
