Bug? RadGrid with GridDropDownColumn

[Michael]

Hello,

I'm using a RadGrid with EditForms. I find that when I use GridDropDownColumn, I get a js error generated by telerik's dynamic code when calling the grid edit form.
If I take GridDropDownColumns out of my grid, everything works fine. Even if I'm using a generic GridDropDownColumn with no datafield, I still get the error.

I can't figure out what's causing this, as it worked the day before and I haven't changed anything.

Here's the error message:

Line: 6
Error: Object doesn't support property or method 'toUpperCase'

Here's my grid:

<telerik:RadGrid runat="server" ID="gridMedications" OnItemDataBound="gridMedications_ItemDataBound" OnInsertCommand="gridMedications_InsertCommand" OnDeleteCommand="gridMedications_DeleteCommand" >
    <MasterTableView AutoGenerateColumns="false" NoMasterRecordsText="<i><b>None - Not taking any medications</b></i>"
        CommandItemDisplay="Bottom" EditMode="EditForms" >
        <CommandItemSettings AddNewRecordText="Add Medication" ShowAddNewRecordButton="true" ShowRefreshButton="false" />
        <EditFormSettings EditColumn-InsertText="Add" EditColumn-ButtonType="PushButton" />
        <Columns>
            <telerik:GridBoundColumn DataField="NameOfMed" HeaderText="Medication" UniqueName="NameOfMed" >

                    <RequiredFieldValidator SetFocusOnError="true" Display="Dynamic" ForeColor="Red" Text=" *Required" />
                </ColumnValidationSettings>
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="ReasonForTaking" HeaderText="Reason for Taking" UniqueName="ReasonForTaking" DefaultInsertValue="" />

            <telerik:GridDropDownColumn DataField="ForAllergies" HeaderText="For Allergies?" UniqueName="ForAllergies" Visible="false" ReadOnly="false" />

            <telerik:GridButtonColumn ButtonType="LinkButton" Text="Remove" CommandName="Delete" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Update:  I had the grid wrapped in an asp:UpdatePanel. Removing the UpdatePanel removes the error, however I prefer using the grid with ajax.

Hello Michael,

Can you please let us know if you are using AjaxControlToolkit references in your application and if yes, try removing them form the project and see how it works?
Also please try replacing the asp UpdatePanel with RadAjaxPanel and see if this makes any difference.
