                <DataGridTemplateColumn Header="Edit Row">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <Button Content="Edit" Click="btnEdit_Click"/>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
                <DataGridTemplateColumn Header="Delete Row">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <Button Content="Delete" Click="btnDelete_Click"/>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
        
        <Button Content="LoadCustomer" Name="LoadCustomer" Height="23" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Margin="0,5,0,0" Click="LoadCustomer_Click" />
    </Grid>
</Window>

和.cs文件代码是： -

and .cs file Code is :-

private void btnEdit_Click(object sender, RoutedEventArgs e)
     {
         try
         {
             gridDataContext datacontext = new gridDataContext();
             registration registrationRow = MyDataGrid.SelectedValue as registration;
             int m = registrationRow.RegId;

             registration Registration = datacontext.registrations.Where(A => A.RegId == m).Single();
             Registration.Name = registrationRow.Name;
             Registration.FName = registrationRow.FName;
             datacontext.SubmitChanges();
             MessageBox.Show("Row Updated Successfully");
             LoadCustomerDetail();
         }
         catch (Exception ex)
         {
             MessageBox.Show(ex.Message);
             return;
         }
     }
