WPF根据单元格值删除datagrid行

Question

I am facing a problem right now, I need to delete a datagrid row based on 1 cell value, code samples below:

XAML:

<DataGrid
    x:Name="AccountGrid"
    IsSynchronizedWithCurrentItem="True"
    GridLinesVisibility="Vertical" 
    ItemsSource="{Binding}"
    CanUserAddRows="False"
    CanUserReorderColumns="False"
    CanUserResizeColumns="False"
    CanUserSortColumns="False" 
    AutoGenerateColumns="False"
    CanUserResizeRows="False" 
    HorizontalContentAlignment="Left"
    ScrollViewer.HorizontalScrollBarVisibility="Disabled" 
    Margin="208,0,0,135"
>
   <DataGrid.Columns>
       <DataGridTextColumn Header="VM-Name" Binding="{Binding Path=vmName}" MinWidth="80" IsReadOnly="True" />
       <DataGridTextColumn Header="Profile" Binding="{Binding Path=profileN}" MinWidth="100" IsReadOnly="True" />
   </DataGrid.Columns>
</DataGrid>

How I add items:

public class AddToGrid
{
   public string vmName   { get; set; }
   public string profileN { get; set; }
}

this.Dispatcher.Invoke(() =>
{
   var dat = new AddToGrid { vmName = clientSockets.Find(item => item.Item1 == current).Item2, profileN = profile.Item1 };
   AccountGrid.Items.Add( dat );
});

What I need to do is Delete a row from the grid , using the VM-Name , Thanks in advance!

Answer 1

1. Rename your AddToGrid class to MyGridRow and move it to be a public type instead of a nested type.
2. Add using System.Linq; and using System.Collections.ObjectModel; to your C# code-behind file.

3. In your XAML code-behind, add this public property:

    public ObservableCollection<MyGridRow> MyGridRows { get; } = new ObservableCollection<MyGridRow>(); 

4. Change your XAML to this:

    <DataGrid ItemsSource="{Binding MyGridRows}" ...> </DataGrid> 

5. Change your code that adds items to this:

    String vmName = clientSockets.Find( item => item.Item1 == current ).Item2; String profile = profileN = profile.Item1; this.MyGridRows.Add( new MyGridRow { VMName = vmName, ProfileN = profile } ); 

6. To remove a row, do this:

    MyGridRow itemToRemove = this.MyGridRows .FirstOrDefault( pair => pair.Item.VMName == "someName" ) if( itemToRemove != null ) { this.MyGridRows.Remove( itemToRemove ); }
