Data Grid Auto generating event not working with Expando

[didi2391]

Current behavior

DataGrid Autogenerating Column is not working with Expando

Expected behavior

Expecting that Data Grid should also work with Expando for Auto Generating columns if bound with an ItemSource

Minimal reproduction of the problem with instructions

I am using an ObservableCollection which is of type dynamic in my View Model which I am binding it to Data grid Item Source

I will be be adding the Columns dynamically at run time into the Expando object and bind it to the above collection

This behavior is not triggering the Auto Generating Column event

hi @didi2391.

I believe you should check this out

It has a user vote also.

Thanks @byrialsen

I went through the link provided and it sounds useful if the row details template is simpler to display a string text or static control with some texts. Below is my scenario,

I have a situation where in I need to show hierarchical data (i.e..,) Nested Data Grid upto 3 level and Columns will be decided only during run time

First Column should be given with an Expander control where in the user can expand / collapse to show / hide the row details template. In my case it is Parent Grid -> Child Grid 1(Expander first column) -> Child Grid 2

I can manage to put an expander as first column for my parent grid

But the inner child grids wont be explicitly available to add columns dynamically in code behind since it is wrapped up under data template

Any suggestions would be helpful to extend the above solution for my case

Yeah, it'd be nice to be able to bind directly to a List/ObservableCollection of ExpandoObject. I know this would make it a lot easier to work with the grid in XAML Studio as well.

@RBrid @harinikmsft any thoughts on this one?

We are not adding features to this DataGrid at this time. If you would like to see this feature in the newly proposed WinUI DataGrid, please add a comment in the WinUI discussion issue. Thanks!
