    I'm using the RadGridView control to display an Observable collection. I also use SelectedItem="{Binding Model.CurrentRow, Mode=TwoWay}" to track which item in the list the grid pointer is on.

    The first column in the grid has a textbox so the user can change the value in the grid. I subscribe to a property change event to validate the content in the textbox.

    The other columns in the grid are not editable.

    The problem:
    When I click on any non-editable column in the grid, the grid Row highlights correctly and the "Model.CurrentRow" updates correctly. However, when I click on a textbox in the first column on a non selected row, that row does NOT receive focus. The grid row focus stays on the prevously selected row, and the "Model.CurrentRow" does not update.

    How can I make the grid row focus on the selected row when i click on an editable textbox in the grid?

    My partial RadGridView xaml:

                    ItemsSource="{Binding Model.MyList}"
                    SelectedItem="{Binding Model.CurrentRow, Mode=TwoWay}">


        Header="Company Name"
       Width="200" >
           <TextBox Text="{Binding CompanyName, Mode=TwoWay}"/>

                            DataMemberBinding="{Binding CustomerType}"
                            Header="Customer Type"

    Hi Jerry,

    Generally RadGridView supports selection out-of-the-box. However, in your case, you want to perform this action using a control placed in CellTemplate of the column(the TextBox).  If you click on the cell which contains the control, you will actually click in the TextBox instead of GridViewRow/GridViewCell, so RadGridView's selection logic will not work. 

    For more information about CellTemplate / CellEditTemplate you can check the Setting CellTemplate and CellEditTemplate documentation article.

    I hope this helps.
