Work around for Master page problem when we use this.DataBind() in content page.

There is a common problem with the master pages, when you use this.databind() in content pages.

The problem is when you submit the content page the below sort of actions will occur.

1. Content page is submitted, posting controls' values to the server.
2. Content page's Load event fires.
3. Master page's Load event fires, this.DataBind() is executed. It happens before any ViewState saving.
4. this.DataBind() causes repopulation of the data-bound Repeater control on the content page.
5. ViewState for controls is still blank at this point, so all properties are reset to an empty string.
6. ViewState tracking methods are called.
7. Button's Click event fires, but all controls have already been reset...
I think there are two easy ways to avoid this behavior. First is calling DataBind() for particular data-bound controls, not for the entire master page. Second is moving this.DataBind() call to content page's PreRender event handler. I used the latter and it worked
