ASP.Net C# gridview

Question

I have a gridview with a linkbutton inside a <HeaderTemplate> . There is an event handler for a click on this button. Now if I bind data to the gridview on every Page_Load event, then this event fires. But if I bind data to the gridview inside if (Page.IsPostBack == false) , then this event doesn't fire.

Is it that after the pageload it realizes there is no data in the gridview hence ignore events generated from the grid?

How do I slove the problem ?

Answer 1

The LinkButton behaves like a Button

The LinkButton control has the same appearance as a HyperLink control, but has the same functionality as a Button control.

That means it triggers a postback when clicked. So the only way to get the click event to fire, is to wire up the handler if Page.Postback=true . (Keep in mind that since HTTP is stateless, if you wire up an event handler on the initial page load, it won't "remember" upon postback.)
