public void onClick(object sender)
{

}

debugger is not firing instead giving error "object expected".
Please help.

Answer 1

The runat=\\"server\\" attribute is not an HTML attribute, but an instruction for ASP.Net to instantiate ASP.Net controls (System.Web.UI namespace) which generate not only HTML, but also ViewState, event handlers etc.

The onclick attribute refers to a JavaScript function that needs to be implemented in HTML or a linked .js file, and not an OnClick method in the C# back-end code.
