[Solved] dropdown within template column of grid

[newbie]

I have a dropdown column within the template column 

<

telerik:GridTemplateColumn HeaderText="Device Type" SortExpression="DeviceDisplayValue" UniqueName="DeviceType" EditFormColumnIndex="1">

<ItemTemplate><asp:Label runat="server" ID="lblDevice" Text='<%# Bind("DeviceDisplayValue") %>'></asp:Label></ItemTemplate>

<EditItemTemplate><telerik:RadComboBox ID="ddlDeviceAW" runat="server" LoadingMessage="Loading Device..." MarkFirstMatch="True" ToolTip="Select a Device"></telerik:RadComboBox></EditItemTemplate>

</telerik:GridTemplateColumn>

I am populating the dropdowns on my ItemCommand event .
If my grid is in edit mode I want to pre select the grid value in the combo box.
I am unable to set that value.

 How can i do that?

You need to bind the SelectedValue of your combobox to the data field for your grid column.

yes but i am not able to get the value of the data field column.
How do i get that?

Well, in the ItemTemplate you are binding to the DeviceDisplayValue, so depending on how you have the data selected to populate your combobox, that might be the field to bind the SelectedValue to.  Does the DataValueField of your combobox correspond to the DeviceDisplayValue?
