How Do I Assign Different Functions/ClickEvents To Buttons Inside A DatagridColumn In WPF?-CodePudding

I have succesfully created a DataGrid with WPF (C#) and bonded the buttons...However I now would like to bind a different event to each individual button instead. I plan to rename the buttons and open different file locations on my PC.

wpfCrudEntities _db = new wpfCrudEntities();
    public static DataGrid datagrid;

    public MainWindow()
    {
        InitializeComponent();
        Load();
    }

    private void Load()
    {
        myDataGrid.ItemsSource = _db.members.ToList();
        datagrid = myDataGrid;
    }

    private void insertBtn_Click(object sender, RoutedEventArgs e)
    {
        InsertPage Ipage = new InsertPage();
        Ipage.ShowDialog();
    }
    private void updateBtn_Click(object sender, RoutedEventArgs e)
    {
        int Id = (myDataGrid.SelectedItem as member).id;
        UpdatePage Upage = new UpdatePage(Id);
        Upage.ShowDialog();
    }
    private void deleteBtn_Click(object sender, RoutedEventArgs e)
    {
        int Id = (myDataGrid.SelectedItem as member).id;
        var deleteMemeber = _db.members.Where(m => m.id == Id).Single();
        _db.members.Remove(deleteMemeber);
        _db.SaveChanges();
        myDataGrid.ItemsSource = _db.members.ToList();
    }
}

}

CodePudding user response：

Using the MVVM pattern you define a ViewModel for your rows.
Then you can use a CommandBinding to bind the Button Click event to the ViewModel of the respective row.

In your case this would be the Member class that needs to be wrapped in a MemberViewModel where the 3 coammnds are defined.

CodePudding user response：

When a button click event fired you can access convert the sender object to a button and do whatever you want.

private void Button_Click(object sender, RoutedEventArgs e)
    {
        var clickedButton= (Button)sender;
        // Do whatever you want
    }

CodePudding user response：

You should be able to do something like this:

private void insertBtn_Click(object sender, RoutedEventArgs e)
{
    if (sender is Button button)
    {
        var dataContex = button.DataContext;
        // This is your item for that row.
        // You just need to cast it if you want to use it.

        InsertPage Ipage = new InsertPage();
        Ipage.ShowDialog();
    }
}
