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?

Grid:

    
                                            <telerikGrid:RadGridView x:Name="equipmentGrid" Grid.Row="1"   
        
                                                    AutoGenerateColumns="False" ShowGroupPanel="True">  
        
                                                <telerikGrid:RadGridView.Columns> 
        
                                                    <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"  /> 
        
                                                    <telerik:GridViewDataColumn     
        
                                                        Header="Include" 
        
                                                        IsCustomSortingEnabled="True"     
        
                                                        IsFilterable="True">  
        
                                                        <telerik:GridViewColumn.CellTemplate> 
        
                                                            <DataTemplate> 
        
                                                                <CheckBox  
        
                                                                    VerticalAlignment="Center"    
        
                                                                    IsChecked="{Binding Path=IsChecked}"    
        
                                                                /> 
        
                                                            </DataTemplate> 
        
                                                        </telerik:GridViewColumn.CellTemplate> 
        
                                                    </telerik:GridViewDataColumn> 
        
                                            </telerikGrid:RadGridView.Columns> 
        
                                        </telerikGrid:RadGridView>

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,
