[Vit100]

Hey guys,
Could u pls explain me difference between this code

<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn >

                   <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <Button  Content="{Binding}"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>

             </telerik:RadGridView.Columns>
        </telerik:RadGridView>

and this one?

<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding}">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn >

            <telerik:GridViewColumn.CellStyle>
                <Style TargetType="telerik:GridViewCell">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate>
                                <Button Content="{Binding}"/>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>

                </Style>
            </telerik:GridViewColumn.CellStyle>

        </telerik:GridViewDataColumn>


    </telerik:RadGridView.Columns>
</telerik:RadGridView>

I think it is same result, right? In first case we define cell via style - template, in second case via CellStyle...

Hello,

 Both techniques and results actually are completely different. 

- In the first snippet you are using DataTemplate which RadGridView will load runtime in a special part of the grid cell. In this case the template will not override anything inside the cell - will just change the "value" part of the cell.

- In the second snippet you are using ControlTemplate to override the entire grid cell template and place your own.

right, this is what I think.
But visual result is same (or similar).
What is purpose of CellTemplate (with DataTemplate inside) if it is possible achive same result with Styles (and Template/ControlTemplate inside)?

Hi,

 Please check once again my previous response for more info about what part of the cell will be changed when you modify these templates.
