Hi, I've got a combo box in an editform in a RadGrid like so-

<telerik:

RadComboBox ID="MyCombo" runat="server" EnableLoadOnDemand="true" OnItemsRequested="MyCombo_ItemsRequested" Width="160"  SelectedValue='<%# Bind("myvalue") %>'></telerik:RadComboBox>

Everything works great until I do some client side validation.  I'm not doing anything fancy, I stripped everything down so there is just one required field validator, and a validation summary control.  Once the validation messagebox comes up, the ItemsRequested event no longer fires.  Any ideas?

Hello Collin,

Can you isolate the problem in a small project and send it to us in a new support thread please?

Thanks

I removed the validation summary, and the client side validators will work without killing the itemrequested method on the radcombo up until I actually click the update or insert button in my RadGrid (I'm in Editform mode, using a table with a few controls added (1 RadCombo, a few textboxes, and 1 drop down).  It looks like when you click the update button the itemsrequested method on the Radgrid dies.  Maybe even though all the validation is on the client side, there is still a small trip to the server made somehow? And that kills the event?

I'll post some sample code if I get some time, but I'm under the gun so I don't know when I'll be able to. The error should be replicatable with a RadCombobox using itemsrequested and a validator.

Hello Collin,

I used the project attached in this KB: (ID#620) Using RadComboBox with AutoComplete as a custom editor in RadGrid and added a RequiredFieldValidator and a ValidationSummary, but the load on demand was working fine.

Let me know if you can reproduce the problem on that project.

Hi.  I've got a very similar problem.

I have a radGrid with an editFormTemplate.  I have a radComboBox and a few normal text boxes and a required field validator on one of the text boxes.  When I click the update/insert button on the editForm and the required field validator fires, the radComboBox no longer opens.

Please advise.

Thanks!

Hi Visconi.  I actually started a new thread and opened a ticket for this problem.  The ticket is 144154 and I attached a project with it.

Thanks for the quick response.

I am having a similar issue with the Q1 2008 SP2 version.  I have a grid with a WebUserControl edit form that contains radComboBoxes and custom validators along with a summary validation control.  When I goto add a new item or edit an item I get a JS error which stops everything from working.  The culprit seems to be:

<SCRIPT type=text/javascript> 
document.getElementById('EditFormControl_vs1').dispose = function() { 
    Array.remove(Page_ValidationSummaries, document.getElementById('EditFormControl_vs1')); 
</SCRIPT>" 

When I enable script debugging and it breaks it is trying to append this element to the HEAD of the document and it says that document.getElementById is null

I have reverted back to sp1 of the controls to test and everything works fine.  Has anyone else had an issue with validation summaries in SP2?

Hi Jason,

Have you tried with the latest version (Futures build)?

If you experience the problem with that version too - please isolate the problem in a small project and send it to us.

Thanks

All the best,

Hello, I have the same behavior that Tomas, I have a radGrid with GridDropDownColumn and GridNumericColumn.  The gridNumericColumn is below radComboBox and a required field validator on this text box was added with ItemCreated event, radComboBox doesn't have validators.  When I click the update/insert button on the editForm and the required field validator fires, the radComboBox no longer opens, but I can select item on radComboBox with up and down keyboard, I can select items in radComboBox but items no longer show.
Thanks
