Hi,
We have a problem with WebCombo's DisplayValue Property In UpdatePanel. After bindind a datasource, we try to change its' display value. But its not effect. (last DisplaValue was still shown). But its the intresting part of it, with second data binding, WebCombo's DisplayValue is set.What is the problem ?
Thanks
Ali
Hi Ali,
Thanks for your feedback. In general, the combination when the WebCombo is inside UpdatePanel, and it has its own AJAX functionality enabled, could cause some undesired effects. It is very important for us to know what your exact configuration of the controls is, i.e. the WebCombo properties that are set, and the CodeBehind code. If you could send over some sample code, this would be of really great help to us.
Best,

Hello,
I am having a similar problem. I have the WebCombo inside an UpdatePanel and that WebCombo has a SelectedRowChangedEventHandler. I can select an item initially, but can never change that selection. The control won't even respond to the click at all. If I remove the SelectedRowChangedEventHandler, the WebCombo doesn't behave this way (still inside the UpdatePanel). Thanks in advance for your advice on this issue.

I also encountered similar problems. How to solve.
Here's what I've been able to observe:
Removing the updatepanel made no difference, the behavior was the same. I have 3 combo boxes, the latter two of which are populated according to the selection made in the first one, using the SelectedRowChanged Event in code-behind. If I select a value in all 3 controls, I can go back and change the selection in the first, which triggers the datasource in controls 2 and 3 to rebind, based on the new selection. this works fine. However, if I don't select an item in the third combobox so that the control appears empty, go back and make a new selection in the first control (which repopulates combos 2 and 3) then combo 2 does not allow me to make a new selection, even though the list contains the new records. Additionally, the text portion of combo 2 remains populated with the selected value from the old list of records. One caveat, if the item I want to select in combo 2 has the same index value as the previously selected item, I cannot select the new value...or at least it doesn't display in the textbox portion of the control. If I select an item with a different index, the control appears to function normally.
Any insight into what's happening would be greatly appreciated!
Sooo...has anyone discovered how to resolve this issue? I having the same problem with placing a webcombo inside an updatepanel. :(
