cascadingdropdown

问题 This issue might be trivial for some but for the life of me, I cannot seem to figure it out. Setup: I have a dropdown ( DropDownList1 ) added at design time. DropDownList1 dynamically creates other dropdowns ( DDL1, DDL2, DDL3 ) at runtime based on the selected value. The dropdown list items is generated every postback as default values. Some of the dynamically created dropdowns ( DLL2, DDL3 ) are also cascading dropdowns wherein DDL3 data items are generated based on DDL2 selected item. I

问题 I have ~50 cascading comboboxes on a form that I want to autofill if only one option is left. I found some code that worked for cboTwo (second combobox), but the other comboboxes aren't filling in automatically. I still have to use the drop down menu to make a selection. Is there any way that I can make all of my comboboxes autofill if there is only one option left in the drop down?
