BeginningEdit is used to get the value of the initial setting. CellEditEnding used to retrieve the modified values and other operations. This is shown in the following code. In XAML:<Grid> <controls:DataGrid x:Name="dataGrid" CellEditEnding="DataGrid_CellEditEnding" BeginningEdit="DataGrid_BeginningEdit" ItemsSource="{Binding}" AutoGenerateColumns="False" GridLinesVisibility="Horizontal"> </controls:DataGrid> </Grid>In C#:private void DataGrid_CellEditEnding(object sender, Microsoft.Toolkit.Uwp.UI.Controls.DataGridCellEditEndingEventArgs e) { string newValue = (e.EditingElement as TextBox).Text; if (startValue != newValue) { //Your own submission, I don't know where you want to submit it } else { //Operation without modification } }private string startValue = string.Empty;private void DataGrid_BeginningEdit(object sender, Microsoft.Toolkit.Uwp.UI.Controls.DataGridBeginningEditEventArgs e) { startValue = (this.dataGrid.SelectedItem as ViewModel).Name;//Change to your own value }You can  get more information about DataGrid inHow to: Implement editing and input validation in DataGrid controlAnd you can download the official example about DataGrid inWindowsCommunityToolkit-DataGrid<o:p></o:p>Best regards,Roy 这篇关于UWP：DataGrid：CellEditEnding获取更改的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
