Updated on Oct 27, 2025
The following tutorial demonstrates how to set up a page with a RadButton control and attach its OnClick server event:
-
In the default page of a new ASP.NET AJAX-enabled Web Application add a RadButton control:
ASP.NET<telerik:RadButton RenderMode="Lightweight" id="RadButton1" runat="server" text="My Button"> </telerik:RadButton>The Text property specifies the text displayed in the RadButton control.
-
To hook to the OnClick server-side event of RadButton switch to Design view of Visual Studio and double click on the button. This operation will insert the following function in the code behind file:
C#protected void RadButton1_Click(object sender, EventArgs e) { }VBProtected Sub RadButton1_Click(ByVal sender As Object, ByVal e As EventArgs) End Subas well as add
OnClick="RadButton1_Click"to the RadButton's declaration.In the Click event handler add the code that you want to be executed when the RadButton control is clicked.
