Attache JavaScript function / code to your button.

C#

btnMyButton.Attributes.Add("onclick", "javascript:altert('Hello')");

If your button is inside update panel did you add <Triggers> section to your update panel ?

<Triggers>
<asp:PostBackTrigger ControlID="btnMyButton" />
</Triggers>

Also set UpdateMode="Conditional" for your Update Panel

Hi,
try this.

ScriptManager.RegisterStartupScript(btnMyButton, this.GetType(), "test", "alert('Hello');", true);
