Question

I have a datagrid consisting primarily of TemplateColumns. I am having the issue where when tabbing through the row, it appears to go to the cell, then the content within the cell (ie a textbox or togglebutton). The ideal situation is that tabbing through the columns puts the focus on the content and skips the cell. I may be interpreting what is happening incorrectly, but visually it appears to be the case. I have tried:

            <DataGridTemplateColumn Header="Group Value"
                                    MinWidth="30"
                                    Width=".02*">
                <DataGridTemplateColumn.CellStyle>
                    <Style TargetType="{x:Type DataGridCell}">
                        <Setter Property="IsTabStop"
                                Value="False" />
                    </Style>
                </DataGridTemplateColumn.CellStyle>
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBox Text="{Binding SomeBinding, 
                                                ValidatesOnDataErrors=True, 
                                                UpdateSourceTrigger=PropertyChanged}"
                                 IsReadOnly="{Binding RelativeSource={RelativeSource FindAncestor, 
                                               AncestorType={x:Type DataGrid}}, 
                                               Path=DataContext.IsReadOnly}"
                                 Style="{StaticResource TextBoxStyle}" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>

But that doesn’t work as I assumed it would. Can anyone help me?

Thanks

You are correct, it does seem to focus the DataGridTemplateColumn before it focuses on the control within it while tabbing.

In my search for a solution, I came across this:

You can attach the FocusAttacher to the control within the template column, and it will steal the focus from it. It worked great for me.
