Hi
I'm trying to use three cascading combo boxes in my EditTemplate for a radGrid (cboCountry, cboProvince, cboCity). They populate properly when I choose to Edit a record in the grid, and I am able to select different values in cboCity. However, when I try to change cboCountry or cboProvince the following error occurs:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control
I guess that after the SelectedIndexChanged event the combo box does not re-bind and instead tries to populate itself from the saved ViewState? Not too sure about this...
I have looked through the videos and documentation and not found an sample that addresses this scenario...
Any help or suggestions would be greatly appreciated
Thanks a lot
