Can you please provide me some resolution to make the cascading dropdowns work as expected when used inside edit mode of AspxGridview.
I am using DevExpress Controls.

My requirement is as follow:

If I select country="United States" then populate the "State" combobox and on selection of "State" populate the "City" combobox.

If I select "country" other then "United States" then populate only "City" combobox with cities of selected "country" and no need to populate the "State" combobox. Also I need to hide the "State" combobox.

i.e. like----------Country---------State--------City
---------ROW1------united states---Alaska-------Douglas
---------ROW4------united states---California---Yuba City

Same is required in Editmode also.
Please help me I need to do it ASAP.

Protected Sub ddlCountry_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
      If ddlCountry.SelectedItem.Value = "US" Then
             ddlState.Visible = True
             txtState.Visible = False
             PopulateState();//Based on Country
             ddlState.Visible = False
             txtState.Visible = True
             PopulateCity();//Based on Country
      End If
End Sub

BTW Do changes based on your need.
