Find control in RadPanelBar and assign it to new one

[Mohamed]

Here's the working code:

In the page.aspx.cs, I define a static variable:

private static TextBox txtName;

 

In the Page_Load() event, I initialize it:

txtName = (TextBox)RadPanelBar1.FindItemByValue("Add").Controls[0].FindControl("TxtName");

The questions is:
1- I had to make the textbox "static" to make the code work, why?
2- The initialization code didn't work when I put it in the if (!IsPostBack) block, I had to make it run  in every page load. why? and is there a better approach to achieve the same functionality?
