推荐答案

RemovedItems项目反映了从选择中删除的项目，而不是从网格中删除的项目。



处理PreviewKeyDown事件，并使用SelectedItems删除所选行的属性：



private void PreviewKeyDownHandler（对象发送者，KeyEventArgs e）{

var grid =（DataGrid）sender ;

if（Key.Delete == e.Key）{

foreach（在grid.SelectedItems中的var行）{

... //执行linq的东西在这里删除

}

}

}



尝试这个让我知道

Hi,

The RemovedItems items reflects the items removed from the selection, and not from the grid.

Handle the PreviewKeyDown event, and use the SelectedItems property to delete the selected rows there:

private void PreviewKeyDownHandler(object sender, KeyEventArgs e) {
var grid = (DataGrid)sender;
if ( Key.Delete == e.Key ) {
foreach (var row in grid.SelectedItems) {
... // perform linq stuff to delete here
}
}
}

try this and let me know

你好，



在WPF中有一个属性SelectedItemfor选择行和删除功能以删除行。



xamal代码：

Hi,

In WPF there is a property "SelectedItem" for selecting a row and "Remove" function for deleting a row.

xamal code:

<datagrid name="datagridTable" selecteditem="{Binding SelectedInformation}">
               ....
</datagrid>

ModalView：

ModalView:

private Information selectedInformation;
public Information SelectedInformation
{
    get { return selectedInformation; }
    set { SetProperty(ref selectedInformation, value); }
}


public UserBase_ViewModal()
{
    delete = new DelegateCommand(DeleteInformationInTable);
}

private void DeleteInformationInTable()
{
   Information.Remove(SelectedInformation);
}

问候，
