[w]

Hi,

    <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" >
                    <telerik:GridViewColumn.CellStyle>
                        <Style TargetType="{x:Type telerik:GridViewCell}" BasedOn="{StaticResource GridViewCellStyle}">
                            <Setter Property="ContentTemplate">
                                <Setter.Value>
                                    <DataTemplate>
                                        <StackPanel Orientation="Horizontal">
                                            <CheckBox x:Name="checkBox"/>
                                            <TextBlock x:Name="textBlockA" Text="AAAAAAA"/>
                                            <TextBlock x:Name="textBlockB" Text="BBBBBBB"/>
                                        </StackPanel>
                                        <DataTemplate.Triggers>
                                            <DataTrigger Binding="{Binding ElementName=checkBox,Path=IsChecked}" Value="false">
                                                <Setter TargetName="textBlockB" Property="Visibility" Value="Collapsed"/>
                                            </DataTrigger>
                                        </DataTemplate.Triggers>
                                    </DataTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </telerik:GridViewColumn.CellStyle>
                </telerik:GridViewDataColumn>

    I use your demo do a test about gridviewcolumn width, As the attach video show. 

 When I check the checkBox in column style,the column with stretch automatically, 

 when I unchecked, the column width  do not get shorter. Is there any method make the column get shorter When I unchecked in the NameColumn

Hi,

Thank you for the provided attached files.

I would suggest you instead of specifying the hiding and showing a TextBlock in the ContentTemplate of the cell, to create a custom DataTemplate and set it to the CellTemplate property of the column. Then you can bind the CheckBox IsChecked property and the Text property of a TextBlock. The next step is to change the Text depending on the IsChecked property of the CheckBox. I have modified your project to demonstrate this approach.
