Hi,

I have the following xaml code:

                               <igGrid:TemplateColumn Key="Test" HorizontalContentAlignment="Center">
                                    <igGrid:TemplateColumn.HeaderTemplate>
                                        <DataTemplate>
                                            <CheckBox x:Name="chkAll" Click="chkAll_Click" Content="Approve All" Grid.Column="0" Margin="10,2,2,2" />
                                        </DataTemplate>
                                    </igGrid:TemplateColumn.HeaderTemplate>
                                    <igGrid:TemplateColumn.ItemTemplate>
                                        <DataTemplate>
                                            <CheckBox x:Name="chkBox" IsChecked="False" IsEnabled="True" Click="chkBox_Click" />
                                        </DataTemplate>
                                    </igGrid:TemplateColumn.ItemTemplate>
                                </igGrid:TemplateColumn>

                                <igGrid:TextColumn  Key="ListPrice" IsReadOnly="True" >
                                    <igGrid:TextColumn.HeaderTemplate>
                                        <DataTemplate>
                                            <TextBlock Text="List Price" TextWrapping="Wrap" Width="50"/>
                                        </DataTemplate>
                                    </igGrid:TextColumn.HeaderTemplate>
                                </igGrid:TextColumn>

How can I disable the columns at runtime?  Thanks!
