Multiple Column Data Template with Different Binding

[Ryan Overton]

My problem is that I am wanting to use 1 data template for multiple colums in a gridview, but I want to bind the element in the data template to a different path.

In the example below I have a template that creates a checkbox.

<Grid.Resources>
            <Style x:Key="CheckboxCellStyle" TargetType="{x:Type telerik:GridViewCell}">
                <Setter Property="ContentTemplate">
                    <Setter.Value>
                        <DataTemplate>
                            <CheckBox VerticalAlignment="Center" IsChecked="{Binding ????}" Click="CheckBox_Click" />
                        </DataTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
</Grid.Resources>

I want to bind the IsChecked property to the binded element in the data colulmn definition.

<telerik:GridViewDataColumn Header="Deleted" DataMemberBinding="{Binding Deleted}" CellStyle="{StaticResource CheckboxCellStyle}"></telerik:GridViewDataColumn>
<telerik:GridViewDataColumn Header="Selected" DataMemberBinding="{Binding Selected}" CellStyle="{StaticResource CheckboxCellStyle}"></telerik:GridViewDataColumn>

Can someone please help me find a solution to this problem?

Hi Ryan ,

How about using an IValueConverter for the binding  and passing the column name as the converter parameter  ?

Let me know if you need a working example on that .

Hello Ryan Overton,

As promised I am attaching a small example. While playing with your scenario I found a way to do this even without converter.
Hope it works for you!

The problem with the sample you provided is that the TwoWay binding mode is not working.  I changed the OneWay binding to TwoWay and when i change a cell value, the value doesn't push back the value to the underlying model.

Is it something that is possible to do?

Hello Eric Belanger,

Yes indeed , messing with the cell value  overrides the default binding logic of the cell. Unfortunately I can not think of a way to do this without explicitly specifying the property  to be edited either in XAML or in code.

There is a hacky solution - to handle to the click event of the checkbox and update the underlying business object in the event handler . However this would require reflection in the handler to obtain the property to be updated and set the value.  It becomes complicated and I am not sure it is a good way at all.
