如何获取DataGridTemplateColumn中的复选框？

Question

I'm creating a window for user delete multiple registers of database using DataGrid for show data and a Button for execute delete

So I putted a DataGridTemplateColumn in the DataGrid and CheckBox in this DataGridTemplateColumn

<DataGrid Name="WordList" Margin="10" Width="230" AutoGenerateColumns="False" 
            SelectionMode="Single" SelectionChanged="WordList_SelectionChanged" 
            CanUserAddRows="False">
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <CheckBox Name="WordChecked" HorizontalAlignment="Center" 
                        VerticalAlignment="Center"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
        <DataGridTextColumn Binding="{Binding Path=Word}" Header="Word" Width="1*" 
            IsReadOnly="True"/>
    </DataGrid.Columns>
</DataGrid>

Please, how to can I access this CheckBox with C# for check it is checked or not?

Answer 1

My recommended approach is to have a List<Item> that is held in the ViewModel and whenever you check the CheckBox in the row the datagrid's SelectedItem will be set and you add the item that was selected to the List . Then when the button is clicked, you delete all the records that are in the List .

Ideally you also want to implement this using Command s.

<DataGridTemplateColumn>
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <CheckBox IsChecked= "{Binding checked, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" Click="CheckBox_Click"/>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

private void CheckBox_Click(object sender, RoutedEventArgs e)
{
   int index = DGItems.SelectedIndex;
   DataRowView drv = (DataRowView)DGItems.Items[index];
}
