单击数据网格复选框列

本文关键字：复选框 网格 数据网 数据 单击 | 更新日期: 2023-09-27 18:16:19

我有一个数据网格，它从项目源动态获取数据。

项目源的一个字段是bool(复选框列)，我想知道用户何时单击复选框。

是哪个事件?

xaml代码:

<Window x:Class="ProtocolAnalyzer.createByProtocol"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="createByProtocol" Height="506" Width="384">
    <Grid Margin="0,0,2,4">
       <DataGrid x:Name="dataGridTable" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="452" Width="245" SelectedCellsChanged="dataGridTable_SelectedCellsChanged" >
                  <DataGrid.Columns>           
                 </DataGrid.Columns>
       </DataGrid>
       <Button Content="Create" HorizontalAlignment="Left" Margin="275,165,0,0" VerticalAlignment="Top" Width="75" Height="75" Click="Button_Click"/>
     </Grid>
</Window>
c#: 

public class TableList
{
    private string _field;
    public string Field
    {
        get { return _field; }
        set { _field = value; }
    }
    private string _val;
    public string Val
    {
        get { return _val; }
        set { _val = value; }
    }
    private bool _calc;
    public bool Calc
    {
        get { return _calc; }
        set { _calc = value; }
    }
}

单击数据网格复选框列

看起来你正在使用自动生成的列或DataGridCheckBoxColumn，所以想知道如何检查CheckBox被选中/未选中。你必须处理CheckBox。单击复选框。选中复选框。在DataGrid级别未检查的附加事件。

<DataGrid  x:Name="DgrdRight" CheckBox.Click="DgrdRight_Click"  CheckBox.Checked="DgrdRight_Checked" CheckBox.Unchecked="DgrdRight_Unchecked"  Grid.Column="1" Grid.Row="0" Margin="10,0,0,0" ColumnWidth="SizeToHeader" AutoGenerateColumns="False">
   <DataGrid.Columns>
      <DataGridTextColumn Header="Title" Binding="{Binding Title}"/>
      <DataGridCheckBoxColumn ... />
   </DataGrid.Columns>
</DataGrid>
代码中的

处理程序:

        private void DgrdRight_Checked(object sender, RoutedEventArgs e)
        {
            System.Diagnostics.Debug.WriteLine("Checked");
        }
        private void DgrdRight_Unchecked(object sender, RoutedEventArgs e)
        {
            System.Diagnostics.Debug.WriteLine("UnChecked");
        }
        private void DgrdRight_Click(object sender, RoutedEventArgs e)
        {
            System.Diagnostics.Debug.WriteLine("Clicked");
        }
