I have 2 combobox A and B. Both of them have AllowCustomText = True and EmptyMessage = "Select A" and "Select B" respectively.
After selecting an item in combobox A, any selection in combobox B would be cleared in client side via OnClientSelectedIndexChanging in combobox A.
Then selected value of combobox A would be set up in Context collection of combobox B via OnClientItemsRequesting and then OnItemsRequested server event will retrieve this value and populate the dropdown values of combobox B.
After selecting an item in combobox B, goes back to combobox A, Hightlight the Selected Text, press DELETE and then click on any area outside combobox A. Empty message of "Select A" is now shown. Then click on dropdown arros of combobox B. No values are refresed in items of combobox B.
Further investigation revealed that selected value of combobox A is not cleared during the last step.
Could anyone advise how to achieve such that the selected value of combobox A would be cleared when last step is undertaken.
Thanks
