[Solved] checkbox column

[hwsoderlund]

I'm trying to add a checkbox column, and I'm not very successful. I've tried setting both the ContentTemplate and the Template property in the CellStyle property for the column, but I can't get any custom content to display at all. Still, it doesn't crash, so I guess I'm not completely out of line. I must be missing something here, please take a look at the code below:

<UserControl x:Class="SilverlightApplication4.Page4"

             Height="600">
    <UserControl.Resources>

               TargetType="telerikGridView:GridViewCell">

                            <CheckBox IsChecked="{Binding}"></CheckBox>
                        </StackPanel>
                    </DataTemplate>
                </Setter.Value>
            </Setter>

Hi hwsoderlund,

Setting CellStyle and HeaderCellStyle properties of the GridViewDataColumn object will be available with our first official beta which is scheduled for the mid-December. You can refer to this thread in our public forum where we discuss the same problem.

P.S. Your way to add custom columns looks OK and will work fine with the beta.
