Question

Given the following XAML:

<ListView Name="UnitProperties" Grid.Column="2">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Property">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <Label Content="{Binding Path=Name}"/>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
            <GridViewColumn Header="Value">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBox Text="{Binding Path=Value}" LostFocus="TextBox_LostFocus_1" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

When the TextBox loses focus, I want to get the value of the label in the first column. How do I do this via code? The Parent property of the textbox is null.

In your TextBox_LostFocus handler, you can get the value of Name property like this –

var dataContext = (sender as TextBox).DataContext;
string labelContent = dataContext.Name;
