Hello,
In my grid view I have two GridViewComboBoxColumn that I want them to be cascade . Basically in need to set each cell in the depending column with different data source but I see that all I can to is to set the data source to the column itself. In this case I can’t see the values of the other rows.
I tried to work on the editor of each cell but its mark as RadDropDownListEditor that I cant chant it data source.

I'm using Q3 version in win forms

        Dim ep As New Telerik.WinControls.UI.Scheduler.Dialogs.EditAppointmentDialog

        Dim evt As New Telerik.WinControls.UI.AppointmentEditDialogShowingEventArgs(ev, ep)
        RadScheduler1_AppointmentEditDialogShowing(Nothing, evt)
    End Sub


But the EditAppointmentDialog not loading. Please help me to do this

In a GridView with 30 plus columns, I am adding few unbound (calculated) columns with expressions. The Expressions refer the other columns in the grid.

The problem is, after initial data load the calculated columns at are at the right end of the grid which are not in the visible area are not being calculated.  The gridview is not calculating the calculated columns that are not in the grid visible area. These columns show up data as soon as I scroll back and forth brining these columns into visible area.

How can make sure the calculated columns are always show data, regardless of their visible position in the grid area.
