How to edit WPF Datagrid cell

This article will show you the way to change the cell in WPF Datagrid.

I have been reading people asking how to change the cell in WPF Datagrid. A lot of article with a lot of theory somehow the code won’t work.

I give you only 2 pieces of code here.

The first one, MainWindow.xaml. Replace your xaml code with the code below.

<Window x:Class=”WpfAppDataGrid.MainWindow”



        Title=”MainWindow” Height=”350″ Width=”525″>


        <DataGrid Name=”dataGrid1″ HorizontalAlignment=”Left” Height=”160″ Margin=”26,23,0,0″ VerticalAlignment=”Top” Width=”419″ AutoGenerateColumns=”True” />

        <Button Content=”Refresh” HorizontalAlignment=”Left” Margin=”26,211,0,0″ VerticalAlignment=”Top” Width=”75″ Click=”Button_Click”/>

        <Button Content=”Modify” HorizontalAlignment=”Left” Margin=”123,211,0,0″ VerticalAlignment=”Top” Width=”75″ Click=”Button_Click_1″/>

        <Label Name=”label1″  Content=”Label” HorizontalAlignment=”Left” Margin=”26,255,0,0″ VerticalAlignment=”Top” Width=”279″/>

        <Button Content=”Access current Row” HorizontalAlignment=”Left” Margin=”230,211,0,0″ VerticalAlignment=”Top” Width=”119″ Click=”Button_Click_2″/>



The second one is the code behind MainWindow.xaml.cs. Again replace your code behind with the code below.

using System.Collections.Generic;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Controls.Primitives;

using System.Windows.Media;


namespace WpfAppDataGrid


    /// <summary>

    /// Interaction logic for MainWindow.xaml

    /// </summary>

    public partial class MainWindow : Window



        List<Person> myList =

                  new List<Person>();

        public MainWindow()





        private void Button_Click(object sender, RoutedEventArgs e)



            myList.Add(new Person() { name = “john”, age = 25, member = true });

            myList.Add(new Person() { name = “jill”, age = 25, member = false });

            myList.Add(new Person() { name = “bill”, age = 15, member = true });


            dataGrid1.ItemsSource = myList;



        private void Button_Click_1(object sender, RoutedEventArgs e)



             DataGridCell gridCell = TryToFindGridCell(dataGrid1, dataGrid1.SelectedCells[1]);

                if (gridCell != null) gridCell.Content = “changed!!!”;       



        static DataGridCell TryToFindGridCell(DataGrid grid, DataGridCellInfo cellInfo)


            DataGridCell result = null;

            DataGridRow row = (DataGridRow)grid.ItemContainerGenerator.ContainerFromItem(cellInfo.Item);

            if (row != null)


                int columnIndex = grid.Columns.IndexOf(cellInfo.Column);

                if (columnIndex > -1)


                    DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(row);

                    result = presenter.ItemContainerGenerator.ContainerFromIndex(columnIndex) as DataGridCell;



            return result;



        static T GetVisualChild<T>(Visual parent) where T : Visual


            T child = default(T);

            int numVisuals = VisualTreeHelper.GetChildrenCount(parent);

            for (int i = 0; i < numVisuals; i++)


                Visual v = (Visual)VisualTreeHelper.GetChild(parent, i);

                child = v as T;

                if (child == null)


                    child = GetVisualChild<T>(v);


                if (child != null)





            return child;



        private void Button_Click_2(object sender, RoutedEventArgs e)


            string name =


            label1.Content = name;




    public class Person


        public string name { set; get; }

        public int age { set; get; }

        public bool member { set; get; }
