Question

I have a gridview in wpf and have a two radio buttons and a button in template column. How do i access the status of radio buttons in the click event of the button?

 <DataGrid>
     <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding TrackingID}" Header="TrackingID" Visibility="Hidden" Width="50" />
        <DataGridTextColumn Binding="{Binding UserFullName}" Header="Name" Width="140" />                                       
        <DataGridTemplateColumn Width="350">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                        <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center" Orientation="Horizontal">
                            <RadioButton Width="50" Content="Yes" GroupName="status" />
                            <RadioButton Width="50" Content="No" GroupName="status" IsChecked="True" />
                            <Button Width="100" Click="Button_Click">View Details</Button>
                        </StackPanel>
                    </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
     </DataGrid.Columns>
 </DataGrid>

I am capturing the event for the button in Button_Click() function. In this function i want to know which radio button has been selected.

private void Button_Click(object sender, RoutedEventArgs e)
        {                
                int trackingid = Convert.ToInt32((((FrameworkElement)sender).DataContext as DataRowView)[0].ToString()); //get the tracking id of the request

                //(((FrameworkElement)sender).DataContext as RadioButton) //not working

        }

Kindly help.

If you don’t want to use binding (in case when your Yes/No is purely a UI property or by whatever reason, you still have an option. Give your RadioButtons names by using x:Name – smth. like “YesRadioButton” and “NoRadiOButton” and then:

Call FinName("YesRadioButton") for the shared container (parent of your RadioButtons).

or

Use ElementName binding, i.e. bind your button’s tag to IsChecked of any of your RadiButtons

<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center" Orientation="Horizontal">
 <RadioButton x:Name="YesRadioButton" Width="50" Content="Yes" GroupName="status" />
 <RadioButton x:Name="NoRadioButton" Width="50" Content="No" GroupName="status" IsChecked="True" />
 <Button Width="100" Click="Button_Click" Tag="{Binding ElementName='YesRadioButton', Path='IsChecked'}">View Details</Button>   
</StackPanel>

then in your button click simply inspect sender’s Tag property.
