How to perform Single click checkbox selection in WPF DataGrid?
I’ve tried these suggestions, and plenty of others I’ve found on other sites, but none of them quite worked for me. In the end, I created the following solution.
I’ve created my own DataGrid-inherited control, and simply added this code to it:
public class DataGridWithNavigation : Microsoft.Windows.Controls.DataGrid { public DataGridWithNavigation() { EventManager.RegisterClassHandler(typeof(DataGridCell), DataGridCell.PreviewMouseLeftButtonDownEvent, new RoutedEventHandler(this.OnPreviewMouseLeftButtonDown)); } private void OnPreviewMouseLeftButtonDown(object sender, RoutedEventArgs e) { DataGridCell cell = sender as DataGridCell; if (cell != null && !cell.IsEditing && !cell.IsReadOnly) { DependencyObject obj = FindFirstControlInChildren(cell, “CheckBox”); if (obj != null) { System.Windows.Controls.CheckBox cb = (System.Windows.Controls.CheckBox)obj; cb.Focus(); cb.IsChecked = !cb.IsChecked; } } } public DependencyObject FindFirstControlInChildren(DependencyObject obj, string controlType) { if (obj == null) return null; // Get a list of all occurrences of a particular type of control (eg “CheckBox”) IEnumerable
ctrls = FindInVisualTreeDown(obj, controlType); if (ctrls.Count() == 0) return null; return ctrls.First(); } public IEnumerable FindInVisualTreeDown(DependencyObject obj, string type) { if (obj != null) { if (obj.GetType().ToString().EndsWith(type)) { yield return obj; } for (var i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++) { foreach (var child in FindInVisualTreeDown(VisualTreeHelper.GetChild(obj, i), type)) { if (child != null) { yield return child; } } } } yield break; } } What does all this do ? Well, each time we click on any cell in our DataGrid, we see if the cell contains a CheckBox control within it. If it does, then we'll set the focus to that CheckBox and toggle it's value. This seems to work for me, and is a nice, easily reusable solution. It is disappointing that we need to write code to do this though. The explanation that the first mouse click (on a DataGrid's CheckBox) is "ignored" as WPF uses it to put the row into Edit mode might sound logical, but in the real-world, this goes against the way every real application works. If a user sees a checkbox on their screen, they should be able to click on it once to tick/untick it. End of story.
DataGrid with single click checkbox
The problem with the checkbox in a WPF DataGrid
By default, if you place a checkbox in a WPF DataGrid, you will have to click twice to check or uncheck the checkbox. And there is a logical explanation. The first click will select the row in the DataGrid, and the second one, the checkbox in that specific row.
In this simple tutorial, we will see how to do it in a better, with one click for both actions.
Solution to the DataGrid checkBox issue
First of all, we will create our simple project and add a Person model:
namespace DataGridSingleClickCheckbox { public class PersonModel { public bool IsSelected { get ; set ; } public string FirstName { get ; set ; } public string LastName { get ; set ; } } } Code language: C# ( cs )
Now, let’s check the View with the DataGrid:
< Window x:Class = "DataGridSingleClickCheckbox.Views.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml" xmlns:prism = "http://prismlibrary.com/" prism:ViewModelLocator.AutoWireViewModel = "True" Title = "{Binding Title}" Height = "350" Width = "525" > < Grid > < DataGrid ItemsSource = "{Binding MyCollection}" AutoGenerateColumns = "False" CanUserAddRows = "False" > < DataGrid.Columns > < DataGridTemplateColumn Header = "Select" > < DataGridTemplateColumn.CellTemplate > < DataTemplate > < CheckBox IsChecked = "{Binding IsSelected, UpdateSourceTrigger=PropertyChanged}" /> < DataGridTextColumn Header = "FirstName" Binding = "{Binding FirstName}" /> < DataGridTextColumn Header = "LastName" Binding = "{Binding LastName}" /> Code language: HTML, XML ( xml )
As you can see, the secret is simply to create a DataTemplate with a checkbox containing UpdateSourceTrigger=PropertyChanged. There is a commented line in the XAML code (DataGridCheckBoxColumn), which is the broken solution, forcing us to click twice, so you can compare them.
Last but not least, our ViewModel:
using Prism.Mvvm; using System.Collections.ObjectModel; namespace DataGridSingleClickCheckbox.ViewModels { public class MainWindowViewModel : BindableBase { private string _title = “DataGrid with single click checkbox” ; public string Title { get { return _title; } set { SetProperty( ref _title, value ); } } private ObservableCollection
_myCollection; public ObservableCollection MyCollection { get { return _myCollection ?? (_myCollection = new ObservableCollection ()); } set { SetProperty( ref _myCollection, value ); } } public MainWindowViewModel ( ) { var person1 = new PersonModel { IsSelected = true , FirstName = “Elon” , LastName = “Musk” }; var person2 = new PersonModel { IsSelected = true , FirstName = “Jeff” , LastName = “Bezo” }; MyCollection.Add(person1); MyCollection.Add(person2); } } } Code language: C# ( cs ) And this is what the result looks like when we run the code:
WPF DataGrid single click checkbox
Here it is! Now your DataGrid has a checkbox per row, and you don’t have to click twice on it to check it.
Here is a link to a previous post about how to put colors in your grid depending on a value.
And another one about the official Microsoft documentation for a WPF DataGrid.
Happy coding! 🙂
Datagrid checkbox check uncheck in single click
2 things. First you have piggy backed unto an already answered question. Most people will not look at already answered so you won’t get much response.
Second when you say some thing didn’t work it tell us nothing. It did something.
I suggest you start a new post, add a link to this post if you think it would be helpful but really you need to tell us what happened, not what did not happen.
BTW I tried your code and it works.

WPF DataGrid CheckBox Single Click Checking/Unchecking
WPF DataGrid has a very annoying behaviour of forcing users to click twice on a checkbox in order to check or uncheck it. There are a number of solutions proposing handling mouse preview events and switching a DataGrid into the edit mode manually. The problem with such solutions is that the require writing quite a lot of extra code that seems to be an overkill for such a minor, yet irritating problem. I propose a better option, to use a DataGridTemplateColumn instead of DataGridCheckBoxColumn.
Indeed, you can easily place a CheckBox inside a DataGridTemplateColumn, bind it to a corresponding property and it will be checkable/uncheckable with a single click.
XAML:
< DataGrid Name ="dgProducts" AutoGenerateColumns ="False" CurrentCellChanged ="dgProducts_CurrentCellChanged" > < DataGrid.Columns > < DataGridTextColumn Header ="Name" Binding ="{Binding Path=Name}" /> < DataGridTextColumn Header ="Price" Binding ="{Binding Path=Price}" /> < DataGridTemplateColumn Header ="In Stock" > < DataGridTemplateColumn.CellTemplate > < DataTemplate > < CheckBox IsChecked ="{Binding Path=IsInStock}" >
Code-behind:
1: public partial class MainWindow : Window 2: { 3: ProductsEntities db = new ProductsEntities(); 4: 5: public MainWindow() 6: { 7: InitializeComponent(); 8: 9: var products = from p in this .db.Products 10: select p; 11: 12: dgProducts.ItemsSource = products; 13: } 14: 15: private void dgProducts_CurrentCellChanged( object sender, EventArgs e) 16: { 17: this .db.SaveChanges(); 18: } 19: }
However, this piece of code still has a problem, in order to send update to a database user must edit any other column after modifying a checkbox. But it’s pretty easy to overcome this issue, first of all, we have to put UpdateSourceTrigger=”PropertyChanged” to the binding section of a checkbox and then handle its Click event.
XAML:
< CheckBox IsChecked ="{Binding Path=IsInStock, UpdateSourceTrigger=PropertyChanged}" Click ="CheckBox_Click" />
Code-Behind:
How to perform Single click checkbox selection in WPF DataGrid?
Problem :
I have a DataGrid with first column as text column and second column as CheckBox column. What I want is, if I click the check box. It should get checked.
But, it takes two click to get selected, for first click the cell is getting selected, for the second clicks the check box is getting checked. How to make the check box to get checked/unchecked with a single click.
I’m using WPF 4.0. Columns in the DataGrid are AutoGenerated.

Answer 1:
For single click DataGrid checkbox you can just put regular checkbox control inside DataGridTemplateColumn and set UpdateSourceTrigger=PropertyChanged .
< DataGridTemplateColumn.CellTemplate > < DataTemplate > < CheckBox IsChecked = "{Binding Path=IsSelected, UpdateSourceTrigger=PropertyChanged}" />
Answer 2:
I solved this with the following Style:
< Style TargetType = "DataGridCell" > < Style.Triggers > < Trigger Property = "IsMouseOver" Value = "True" > < Setter Property = "IsEditing" Value = "True" />
It’s of course possible to adapt this further for specific columns …
Answer 3:
First of, I know this is a pretty old question but I still thought I’d try and answer it.
I had the same problem a couple of days ago and came across a surprisingly short solution for it (see this blog). Basically, all you need to do is replace the DataGridCheckBoxColumn definition in your XAML with the following:
< DataGridTemplateColumn Header = "MyCheckBoxColumnHeader" > < DataGridTemplateColumn.CellTemplate > < DataTemplate > < CheckBox HorizontalAlignment = "Center" VerticalAlignment = "Center" IsChecked = "{Binding Path=MyViewModelProperty, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
The upside of this solution is obvious – it’s XAML-only; thus it effectively refrains your from burdening your code-behind with additional UI logic.
Answer 4:
To make Konstantin Salavatov’s answer work with AutoGenerateColumns , add an event handler to the DataGrid ‘s AutoGeneratingColumn with the following code:
if (e.Column is DataGridCheckBoxColumn && !e.Column.IsReadOnly) { var checkboxFactory = new FrameworkElementFactory( typeof (CheckBox)); checkboxFactory.SetValue(FrameworkElement.HorizontalAlignmentProperty, HorizontalAlignment.Center); checkboxFactory.SetValue(FrameworkElement.VerticalAlignmentProperty, VerticalAlignment.Center); checkboxFactory.SetBinding(ToggleButton.IsCheckedProperty, new Binding(e.PropertyName) { UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }); e.Column = new DataGridTemplateColumn { Header = e.Column.Header, CellTemplate = new DataTemplate { VisualTree = checkboxFactory }, SortMemberPath = e.Column.SortMemberPath }; }
This will make all of DataGrid ‘s auto-generated checkbox columns be “single click” editable.
Answer 5:
Based on blog referenced in Goblin’s answer, but modified to work in .NET 4.0 and with Row-Selection Mode.
Notice that it also speeds up DataGridComboBoxColumn editing – by entering edit mode and displaying dropdown on single click or text input.
XAML:
< Style TargetType = "{x:Type DataGridCell}" > < EventSetter Event = "PreviewMouseLeftButtonDown" Handler = "DataGridCell_PreviewMouseLeftButtonDown" /> < EventSetter Event = "PreviewTextInput" Handler = "DataGridCell_PreviewTextInput" />
