It is strange if i use find control for linkbutton, i am getting empty gridview.

Hello,
I use Gridview and binding from database. And, i use OnRowDataBound="Gridprepack_RowBound" .
protected void Gridprepack_RowBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { Label lblqty = (Label)e.Row.FindControl("lblqty1"); Label lblpriceprepack = (Label)e.Row.FindControl("lblpriceprepack"); Label lblpackprice = (Label)e.Row.FindControl("lblpackprice"); Label lblmapprice = (Label)e.Row.FindControl("lblmapprice"); Label lbladdtocart = (Label)e.Row.FindControl("lbladdtocart"); LinkButton lnkviewcart12 = (LinkButton)e.Row.FindControl("likbtn");
}

as i used LinkButton find control, my whole gridview shows just blank. But no Error ! No exception though..
once i removed this line "LinkButton lnkviewcart12 = (LinkButton)e.Row.FindControl("likbtn") ...
