I have the following grid definition:
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" AllowMultiRowEdit="true"
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" AllowMultiRowEdit="true"
GridLines="None" Skin="Web20"
OnPreRender="RadGrid1_PreRender"
>
<MasterTableView EditMode="InPlace" TableLayout="Fixed">
<Columns>
</Columns>
</MasterTableView>
</telerik:RadGrid>
Instead of the default textbox, I want the generated columns to be a drop down list. All of the selections are the same. I have to do this at runtime as I don't know how many rows or columns I have until then.
Ideas?

Hello Chris,
I hope hiding the default textbox control in editmode and adding the new dropdownlist control will help you to achieve the requirement.
ASPX:
C#:
Also another approach is creating the columns dynamically which includes RadComboBox inside EditItemTemplate. Go through the following link to know more on creating the columns programmatically.

That didn't work at all.
I came close with this answer: http://www.telerik.com/community/forums/aspnet-ajax/grid/createcolumneditor-event-to-change-editor-control-type.aspx#1360068
However, the problem with that one is that it doesn't work when AllowMultiRowEdit is true. It will only show the last line of controls.

Thanks ! This is exactly what I needed. It's nice to use the automated forms for ease and just override a few items for customizations.
Works great.
