Have you checked out the answer here? stackoverflow.com/a/11455262/382214 - ewitkows
Just to double check... have you put a breakpoint at the very top of Deny_Click1. You're swallowing potencial exceptions so maybe the problem is that there is an exception but you didn't realize about it. - Claudio Redi
@ClaudioRedi i put Response.redirect("home.aspx") it did not fire!! - Mohammad Olfatmiri
@ewitkows thats not my problem.. - Mohammad Olfatmiri
Remove the Onclick event on your button and set the commandname and argument there too. - Ahmed ilyas

It is probably firing, but it will throw an exception (which your catch block ignores). The exception is because of this line:

LinkButton Link = (LinkButton)sender;

The sender is a Button, not a LinkButton, so the cast is not valid and an exception will be thrown.

Buttons inside GridView do not respond to direct events. They have to go through GridView's RowCommand event implementation. I've seen that you have implemented OnRowCommand="GridView1_RowCommand". So now you need make following change to image button:

<asp:ImageButton ID="accept"  runat="server" CommandName="Accept" />

Now look for "Accept" command name in your GridView1_RowCommand event handler.

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
  if (e.CommandName == "Accept")
  {
    // Your code goes here
  }

}

I hope this helps.
