Wpf C＃嵌套数据网格 [英] Wpf C# nested datagrid

问题描述

我有一个包含第二个数据网格的数据网格。我想分别处理每个数据网格的双击事件。问题是来自嵌套数据网格的事件甚至调用来自其父数据网格的双击事件。



XAML文件

I have a datagrid which includes a second datagrid. I want to handle the double click event for each datagrid seperatly. The problem is that the event from the nested datagrid calls even the double click event from its parent datagrid.

XAML File

 <DataGrid x:Name="dg_tab_100" MouseDoubleClick="dataGrid0_MouseDoubleClick">
   
   <DataGrid.RowDetailsTemplate >
                  <DataTemplate>
                    <DataGrid x:Name="gridPersons" MouseDoubleClick="dataGrid1_MouseDoubleClick" / >
                  </DataTemplate>
  < /DataGrid.RowDetailsTemplate>

</ DataGrid>

C＃代码

C# Code

   private void dataGrid0_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
//CODE DATAGRID 0
	}


   private void dataGrid1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
//CODE DATAGRID 1
	}

我有什么试过：



带有样式和事件设定器的Datagrid Colums

What I have tried:

Datagrid Colums with style and event setter

推荐答案

我的解决方案

My solution

public bool EventHandler = false;

  private void dataGrid0_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            if (EventHandler == false) {
              //CODE DATAGRID 0
            }
            EventHandler = false;
        }

        private void dataGrid1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            //CODE DATAGRID 1
            EventHandler = true;
            
        }

您可以使用来源属性用于检查事件源的事件参数。类似于：

You can use the Source property of the event argument to check the event's source. Something like:

private void dataGrid0_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
	if (e.Source == dg_tab_100)
	{
		//CODE DATAGRID 0
	}
} 

private void dataGrid1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
	if (e.Source == gridPersons)
	{
		//CODE DATAGRID 1
	}
}
