ASP .NET Web Controls

[codeWarrior]

I'm having trouble working with web controls from the C# code behind file. Some controls are accessible to me programatically, and some are not

For example, I trying to hide, or display an <asp:Table> on post back on the page, here is my code

HTML

<asp:Table id="commentTable" runat="Server"><asp:TableRow><asp:TableCell>Some Text</asp:TableCell></asp:TableRow></asp:Table

C# Code Behin

protected System.Web.UI.WebControls.Table commentTable

private void Page_Load(object sender, System.EventArgs e

commentTable.Visible = isPostBack


I get this error anytime I run the app

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Source Error:

Line 37: commentTable.Visible = isPostBack
