I have several combo boxes on a single web page.  I will include both the display (.aspx) code and the code behind code below shortly.

After page load, selecting an entry from the first combo box (Cycle) triggers the loading of both the second (Election) and third combo boxes (Political Race).  All of this cascading works fine, until (for example) when the page does not validate due to the custom validation on the very last textbox on the page (Web Site URL).

If an error is found on this custom validation, the page is refreshed and both the second and third combo boxes (Election and Political Race) have lost their selections.  Once this happens, then errors are displayed for the second and third combo boxes and for the "Web Site URL" as well and this creates a kind of "deadly embrace" that the user cannot remove themselves from.

My basic question is "Why are the Election and Political Race combo boxes losing their selection during this validation process and what can I do to prevent this loss?

Here is the .aspx code.  The code behind follows.


Now the code behind...


Sorry to have to load so much code.  I hope you can give me an idea of how to resolve this problem.

Thanks in advance!

Hello,

I use the RadWindow for pop-up window to gather different info from users. In one case, I have the pop-up window that looks like no formatting was applied correctly (in the attached image). It doesn't happen with all the pop-up windows. Just that one! I have tried to research but found no similar case. Since this is for our intranet site, it is not possible for me to send the layout to you. Any thought on what might have cause this issue. Thanks in advance.

Tri

PS: I am using version 2011.2.915.40.

Hi All,

I'm having a problem with postbacks not functioning consistently when a radtooltipmanager exists.
I have multiple RadTextBoxes on a page (all autopostback to the server). I click on one and edit it then press enter to postback (this works), then click on another RadTextBox edit it and press enter to postback and for some reason it never posts back. The same behaviour occurs if I just click out of the text boxes without hitting enter.
The behaviour doesn't appear to happen with RadComboBox's.

Is there a fix for this?

Cheers,
- Will
