I have followed the advice on this forum post below by adding
and removing a dummy object in my collection.
This will force a RadGrid to show data that meets the filters criteria after the filter has been applied.
Unfortunately this breaks my cell flashing user control, which relies upon FrameworkElement.IsLoaded being true but is always false when doing the suggested fix from the forum post.
This is because the user control now being instantiated in CreateCellElement on each update rather than being reused.
How can I send a sample project? You can see when you run the solution, if you filter on the InAuction column and set it to true, you will see the rows being added but no cell flashing for the StockPrice column.
How can I fix the issue?
