UWP：DataGrid：CellEditEnding获取更改 [英] UWP: DataGrid:CellEditEnding getting changes

问题描述

获取更改并提交更改的正确方法是什么？

< pre class ="prettyprint">< controls：DataGrid x：Name =" dataGrid" CellEditEnding = QUOT; dg_CellEditEnding" ItemsSource =" {x：Bind ViewModel.Source}"的AutoGenerateColumns = QUOT假QUOT; GridLinesVisibility = QUOT;水平"> < controls：DataGrid.Columns>

 private async void dg_CellEditEnding（object sender，DataGridCellEditEndingEventArgs e）{} 

解决方案

   如果您想获取更改并提交项目，则应设置两个事件：CellEditEnding和BeginningEdit。 BeginningEdit用于获取初始设置的值。 CellEditEnding用于检索修改后的值和其他操作。
这显示在以下代码中。 

在XAML中：

< ;网格和GT; 
< controls：DataGrid x：Name =" dataGrid" 
 CellEditEnding =" DataGrid_CellEditEnding" 
 BeginningEdit =" DataGrid_BeginningEdit" 
 ItemsSource =" {Binding}"的AutoGenerateColumns = QUOT假QUOT; 
 GridLinesVisibility =" Horizo​​ntal"> 
< / controls：DataGrid> 
< / Grid> 
 

在C＃中：

 private void DataGrid_CellEditEnding（object sender，Microsoft.Toolkit.Uwp。 UI.Controls.DataGridCellEditEndingEventArgs e）
 {
 string newValue =（e.EditingElement as TextBox）.Text; 
 if（startValue！= newValue）
 {
 //你自己的提交，我不知道你想在哪里提交它
} 
 else 
 {
 //无需修改的操作
} 
} 
 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为了你自己的价值
}

What is the proper way of getting the changes and committing them?

<controls:DataGrid	x:Name="dataGrid"	CellEditEnding="dg_CellEditEnding"	ItemsSource="{x:Bind ViewModel.Source}"	AutoGenerateColumns="False"	GridLinesVisibility="Horizontal">	<controls:DataGrid.Columns>

private async void dg_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e){}

解决方案

Hi,

   If you want to get changes and committing items, you should set two events: CellEditEnding and BeginningEdit. 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
        }
