Question

I’m trying to create a datagrid with auto generating columns.
Let’s say my Collection is a property named Articles of my viewmodel of type ObservableCollection<ArticleWrapper>.

I bind now the ItemsSource to this collection:

<wpf:DataGrid ItemsSource={Binding Articles} />

The class ArticleWrapper is like this:

[c#]
public class ArticleWrapper
{
    public ArticleConfigurationSet ArticleConfigurationSet { get; set; }
    public string Description { get; set; }
}


[vb.net]
Public Class ArticleWrapper
    Public Property ArticleConfigurationSet As ArticleConfigurationSet
    Public Property Description As String
End Class

The class ArticleConfigurationSet is like this:

[c#]
public class ArticleConfigurationSet
{
    public string Key { get; set; }
    public int Number { get; set; }
}

[vb.net]
Public Class ArticleConfigurationSet
    Public Property Key As String
    Public Property Number As Integer
End Class

The autogenerated columns look like this (please forget about the CustomEntries):

But now my problem: I want to bind the displayed data to my ArticleConfigurationSet property. But I cannot change my ItemsSource Binding, because the SelectedItem property of the datagrid must be of ArticleWrapper (for command handling).

The datagrid should also look like this:

Do you have any ideas how to do this?

Answer 1

why not set AutoGenrateColumns = false and create the gridcolumns and bindings dynamic in dependence of your ArticleConfigurationSet properties?

you dont have to change the view and you can do what you want.

edit: i mean you can iterate through your ArticleConfigurationSet properties(e.g. with reflection) and create the Gridcolumns and bindings by you.

 foreach(var p in properties)
 {
      //grid add new gridcolumn
      //set binding to ArticleConfigurationSet Property Name
      var b = new Binding("ArticleConfigurationSet"+p.Name);
      //add binding to gridcolumn
 }
