tabcontrol: Problem accessing textboxes on other tabpages

I have a VB.Net MDI project with a child form that has a tabcontrol and serveral tabpages on it.  I have textboxes and datagrids bound to several datasets.  I am having a problem getting information that is located in textboxes on other tabpages.  After doing a lot of searching I have read that the solution is to go through all of the tabpages to make them active (aware?) at load time.  Will this work even if there is nothing bound at load time?  Is there a better answer?

the code I have used to step through the tabpages goes like this:
tabOrderEntry.SelectedTab = tabCustomer
tabOrderEntry.SelectedTab = tabBillTo
tabOrderEntry.SelectedTab = tabOrder  
tabOrderEntry.SelectedTab = tabItems  Etc.

Is there a way to make all of the textboxes from all of the tabpages accessable at the same time, or a way to reference them?

Thanks for any help.

The problem is that TabPages are not fully loaded until they are visible to save time and resources.

Your workaround is the one I know!

This answers my Suspicions.

I did find that I could reference items by using the systax:

Me.tabOrderInfo.Controls.Item(51).Text.ToString

This will get the information from the other TabPage when it would not using:

txtInvoiceNo.Text.ToString

I will move up my SelectedTab. SelectedTab, SelectedTab further in my code and see if that cleans up my issues.

Thanks,
