Databound control value issue

[David A.]

Hi,

I have a pageview with several tabs that have databound controls (textboxes).  When the user closes the form, I am validating these textbox values.  The problem is if a tab is not selected the textboxes are showing an empty text value (not the databound value) in code (validation fails).  As soon as I select the tab on the form the textboxes are populated and the validation succeeds.  Is there a way to "force" the textboxes in unselected tabs to populate their underlying values?

Thanks!

Hello David,

The problem is not just that the textboxes do not hold the right value, the problem is that the handles for the page are created just when you first select a page, so before you select that page nothing will be created (initialized) for that page.

So if you really would like to force this, then i would suggest on page load to select each page. It should work like this.

Hope this helps, if you have any other questions or comments, please let me know,

Best Regards,

Thank you.  That sounds like it is a great performance benefit.

This is pretty old, has this been addressed.  I spent hours trying to figure out why my controls that are databound, would not update/refresh until the page was selected.

Hi, Mark,

According to the provided brief information, it wouldn't be easy to determine what causes the undesired behavior on your end. I would kindly ask you to submit a support ticket with more detailed information about the precise case . Thus, we would get better understanding of the precise case and think about an appropriate solution. A sample runnable project would be also greatly appreciated. Thank you in advance for your cooperation.

I am looking forward to your reply.
