How to change ComboBoxStyle in GridViewComboBoxColumn of RadGridView when i Edit the cell.

<telerik:GridViewComboBoxColumn Header="Location" DataMemberBinding="{Binding AlertLocationId}"
UniqueName="AlertLocation" SelectedValueMemberPath="Id" DisplayMemberPath="Name"
Style="{DynamicResource GridViewColumnStyle}"/>

Hello JIJIKO,

To achieve your requirement, you can create a custom class that derives from GridViewComboBoxColumn and override its CreateCellEditElement() method. There you can set the Style or any other property of the created RadComboBox control.

Does this mean i cannot set the DynamicResource as  Combobox's Style in xaml?

It looks like I mislead you a bit with the CreateCellEditElement() method. You can use it, but f you want to provide a style dynamically from XAML, you will need to expose an additional property in the custom column and pass it in code. 

However, it turns out that the EditorStyle property that comes from the GridViewBoundColumnBase class (inherited by GridViewComboBoxColumn) will work in your case.

<telerik:GridViewComboBoxColumn.EditorStyle>
	<Style TargetType="telerik:RadComboBox">
		<Setter Property="Opacity" Value="0.5" />
	</Style>
</telerik:GridViewComboBoxColumn.EditorStyle>
