I have a grid that could have as many as 3000 rows in it.  I have 5 ReadOnly columns and one CheckBox column that is enabled.  The user needs to:

  • move from record to record using the up/down keyboard arrows.
    • On moving up and down, the focus needs to remain on the CheckBox column.
    • User should have a visual queue which row and column is selected.  Currently, row is obvious; column is not.


  • press the spacebar to toggle the checkbox value to the next/other value.
    • I'm not convinced that putting a KeyDown event handler on the CheckBox is valid because it seems the keydown is actually on the cell that contains the CheckBox.

How can I accomplish this?


                                <telerikGrid:RadGridView x:Name="equipmentGrid" Grid.Row="1"   
                                        AutoGenerateColumns="False" ShowGroupPanel="True">  
                                        <telerikGrid:GridViewDataColumn Header="System"   
                                            DataMemberBinding="{Binding Root}" IsReadOnly="True"  /> 
                                        <telerikGrid:GridViewDataColumn Header="Area"   
                                            DataMemberBinding="{Binding Area}" IsReadOnly="True"  /> 
                                        <telerikGrid:GridViewDataColumn Header="Process Cell"   
                                            DataMemberBinding="{Binding ProcessCell}" IsReadOnly="True"  /> 
                                        <telerikGrid:GridViewDataColumn Header="Unit"   
                                            DataMemberBinding="{Binding Unit}" IsReadOnly="True"  /> 
                                        <telerikGrid:GridViewDataColumn Header="Module"   
                                            DataMemberBinding="{Binding Module}" IsReadOnly="True"  /> 
                                                        IsChecked="{Binding Path=IsChecked}"    

Note:  This is how the out-of-the-box CheckBoxColumn in the MS Grid works.

Hi Joel Palmer,

We will add a special CheckBox column in our RadGridView, which will cover this requirement, with the next official release (2010.Q1). Meanwhile I'm attaching a sample project which demonstrates how to meet your goals by creating a custom column. Let me know how this works on your end.

Kind regards,
