Hi, I want to add an option to show only selected rows or all rows in a grid with multi-select. Is their an easy way to do this (are the selected rows filterable in some way)?

I can get it to work by filtering the datasource but can not undo it easly with out requerying data.

Use the items provided by @bind-Value, check our selection demos for reference.

Hi
I am using bind value (see code below) and I can use the selected rows to filter Data, but it changes the Data source so I can not undo it. Or am I going about this the wrong way, is there a way to apply filter to grid using the Selected values?
