Hi,

I have a RadGridView that has a RowDetailTemplate that we are using a listbinding to show another grid showing details associated with the parent row item.

I'm setting RowDetailVisibilityMode to Visible to show the nested RowDetailTemplate expanded by default. All of this data is loaded from a monolith API call and then held in memory.

We are using an ICollectionView to filter the parent grid using fields in the UI.

This all works, BUT when the filter is released using a command and the entire grid is restored from the collection in memory, the child (RowDetailTemplate) grid only shows the values in the first column of the grid rows. The others don't show up unless I resize the App window, then they all show up.

So, I know the data is there, but it's not showing up without resizing the window after we restore the collection.

Is there a known issue with this behavior or a setting that I can apply to either the parent or child grid that will force the column values to re-render in the UI?

Hello billy,

With the currently presented information, I cannot provide suggestions regarding this scenario. Would it be possible to isolate this behavior in a sample project that I could test?

No answers yet. Maybe you can help?
