Hi,
I'm trying to update ComboBox using ASPxCallbackPanel.
I have two ASPxCallbackPanels as in ProcessSo.aspx.
First one has ASPxComboBoxMarket which gets updated when ASPxButtonRefresh is clicked.
The callback itself is working. I confirmed that ASPxCallbackPanelMarket_Callback gets called and update.
My problem is that ASPxComboBoxMarket.DataBind() doesn't seem to work.
After this function is called, other function ProcessSoSubstituteSku() tries to access ASPxComboBoxParam.SelectedItem.ToString(), but it fails as SelectedIndex = -1 and SelectedItem is null.
Second one has the same issue.
Can you please let me know what am I missing?
Thanks,
Mark
