link button text change

Use RowDataBound and place your logic there:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 

{ 

if (e.Row.RowType == DataControlRowType.DataRow) 

{ LinkButton lbtAction = (LinkButton) e.Row.FindControl("lbtAction");

 Label lblStatus = (Label) e.Row.FindControl("lblStatus");  

       bool active = lblStatus.Text == "Active";  

       lbtAction.Text = active ? "Disable" : "Enable";

 string onClientClick  = string.Format("return confirm('Do you want to {0}?')",

 active ? "Disable" : "Enable");  

       lbtAction.OnClientClick = onClientClick; } }
