Nothing loading

Hi All.

I was using the nuget package in .NET Framework 4.7.2 and it was working fine. I then migrated the project to .NET 6 and then the gird no longer appeared. I’m not sure if it is because I am using .NET 6 or if I am doing something wrong, but any help would be much appreciated.

My current code: XAML:

xmlns:control="http://filterdatagrid.control.com/2021"
...
<control:FilterDataGrid x:Name="filterGrid" Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="2"></control:FilterDataGrid>

XAML.CS:

...
filterGrid.DataContext = viewModel;
filterGrid.ItemsSource = viewModel.Contracts;
filterGrid.AutoGeneratedColumns += (_, _) =>
{
     filterGrid.Columns.RemoveAt(0);
     filterGrid.Columns.Move(10, 0);
     filterGrid.Columns.Move(13, 0);
     filterGrid.Columns[0].Header = "Contract (JobID)";
     filterGrid.Columns.RemoveAt(7);
     filterGrid.Columns.RemoveAt(13);
     filterGrid.Columns.RemoveAt(13);
     filterGrid.Columns.RemoveAt(13);
     filterGrid.Columns.RemoveAt(13);
};

Contracts is a IEnumerable<Contract> which is loaded before this code.

Same problem. 1.2.5 is okay. 1.2.6 is not working.

Hi all,

The problem with loading probably stems from where and when you feed the “ItemsSource” property of FilterDataGrid . FilterDataGrid works the same way as a Datagrid. If you don’t implement INotifyPropertyChanged to notify that the “ItemsSource” property has been updated, use the “Loaded” event of FilterDataGrid to do further processing on the columns. Here is an example :

// MainWindows.cs List<User> items = new List<User> { new() { Name = “John Doe”, Mail = “[e-mail]”, Age = 42, Sex = SexType.Male }, new() { Name = “Jane Doe”, Mail = “[e-mail]”, Age = 39, Sex = SexType.Female }, new() { Name = “Sammy Doe”,Mail = “[e-mail]”, Age = 13, Sex = SexType.Male }, new() { Name = “Donna Doe”,Mail = “[e-mail]”, Age = 13, Sex = SexType.Female } };

filterGrid.ItemsSource = items;

        filterGrid.Loaded += (_, _) =>
        {
            filterGrid.Columns.RemoveAt(3);
            filterGrid.Columns.Move(1, 0);
            filterGrid.Columns.Move(2, 1);
            filterGrid.Columns[0].Header = "Contract (JobID)";
        };

// test class public enum SexType { Male, Female };

public class User { public string Name { get; set; }

public int Age { get; set; }

public string Mail { get; set; }

public SexType Sex { get; set; }

}

Please see the demo applications provided with the code of FilterDataGrid.

Best regards
