[Solved] Column IsReadOnly

[Jack]

Is this not a bindable property?  I get an ParserError trying to bind it to my BO

<telerikGridView:GridViewDataColumn UniqueName="IsNotApplicable" HeaderText="N/A" DataMemberPath="IsNotApplicable" IsReadOnly="{Binding Path=GuiAllowNotApplicable}">
                    <telerikGridView:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="N/A" Visibility="{Binding Converter={StaticResource ConvertBoolToVisibility}, Mode=OneWay, Path=IsNotApplicable}"/>
                        </DataTemplate>
                     </telerikGridView:GridViewDataColumn.CellTemplate>
                    <telerikGridView:GridViewDataColumn.CellEditTemplate>
                    <DataTemplate>
                            <CheckBox Content="N/A" IsChecked="{Binding IsNotApplicable, Mode=TwoWay}" Visibility="{Binding Converter={StaticResource ConvertBoolToVisibility}, Mode=OneWay, Path=GuiAllowNotApplicable}"/>
                        </DataTemplate>
                    </telerikGridView:GridViewDataColumn.CellEditTemplate>
                </telerikGridView:GridViewDataColumn>

Basically I want to lock the user out of the cell unless my BO GuiAllowNotApplicable is True and then I will show my N/A CheckBox to modify the settings of BO.IsNotApplicable

Thanks

Hi Jack,

GridViewDataColumn is a DependencyObject, which properties cannot be databound due to a limitation of the Silverlight platform. What you can do is to attach an event handler for PropertyChanged event of your business object and change IsReadOnly property of the column when GuiAllowNotApplicable property is changed.

Hope this helps.

Stefan,

Thanks for the tip - more Silverlight fun and learning for me.  Okay so I can get the BO that changed via a collectionChanged event on my list BO but how do I go from the 'BO row' to the 'Grid Row' to set the column?

Also I need to disable the Cell, not the whole column - is that going to work?

Thanks

Hello Jack,

You can subscribe for BeginningEdit event of RadGridView and set GridViewBeginningEditRoutedEventArgs.Cancel property to true when you want to cancel the cell edit operation.
