 # How to use the editing related events in GridCheckBoxColumn of WinUI DataGrid (SfDataGrid)?
-This example illustrates how to use the editing related events in GridCheckBoxColumn of WinUI DataGrid (SfDataGrid).
+
+The **BeginEdit** and **EndEdit** events are not triggered for [GridCheckBoxColumn](https://help.syncfusion.com/cr/winui/Syncfusion.UI.Xaml.DataGrid.GridCheckBoxColumn.html) when check or uncheck the CheckBox control in **GridCheckBoxColumn** in [WinUI DataGrid](https://www.syncfusion.com/winui-controls/datagrid) (SfDataGrid). However, you can trigger the **GridCheckBoxColumn** when the CheckBox control is checked or unchecked by using the [CurrentCellValueChanged](https://help.syncfusion.com/cr/winui/Syncfusion.UI.Xaml.DataGrid.SfDataGrid.html#Syncfusion_UI_Xaml_DataGrid_SfDataGrid_CurrentCellValueChanged) event.
+
+
+```C#
+
+//Event subscription
+this.dataGrid.CurrentCellValueChanged += OnCurrentCellValueChanged;
+
+//Event customization
+public void OnCurrentCellValueChanged(object sender, CurrentCellValueChangedEventArgs args)
+{
+    int columnindex = dataGrid.ResolveToGridVisibleColumnIndex(args.RowColumnIndex.ColumnIndex);
+
+    if (columnindex < 0)
+        return;
+
+    var column = dataGrid.Columns[columnindex];
+
+    if (column is GridCheckBoxColumn)
+    {
+        var rowIndex = this.dataGrid.ResolveToRecordIndex(args.RowColumnIndex.RowIndex);
+
+        if (rowIndex < 0)
+            return;
+
+        RecordEntry record = null;
+
+        if (this.dataGrid.View != null)
+        {
+            if (this.dataGrid.View.TopLevelGroup != null)
+            {
+                //Get the record when grouping applied in SfDataGrid
+                record = (this.dataGrid.View.TopLevelGroup.DisplayElements[rowIndex] as RecordEntry);
+            }
+            else
+            {
+                record = this.dataGrid.View.Records[rowIndex] as RecordEntry;
+            }
+
+            if (record != null)
+            {
+                //Checkbox property changed value is stored here.
+                var value = (record.Data as OrderInfo).Review;
+            }
+        }
+    }
+}
+
+```
