Hi Bob Elvin,

The most simple way would be by clearing the SelectedRows before you send PostBack using the following JavaScript code:

ISGetObject("WebGrid1").RootTable.SelectedRows = [];

How do you clear selected items when RestoreRowSelection="All"?

I have a grid that has the filter bar, multiple-row selection, and RestoreRowSelection="All" turned on. The grid is not using a row checker column. Basically here's the RootTable settings...

... and here are the layout settings ...

My issue is with the RestoreRowSelection="All". This grid is listing employees for a given location; when the user changes the location via a web combo the grid is refreshed with a new list of employees for the new location. However, the grid.RootTable.GetCheckedRows() always returns the list of selected employees from the old location no matter what I do. I've tried grid.RootTable.GetSelectedRows().Clear, I've tried forcing the list clear with grid.ClearCachedDataSource and grid.RebindDataSource, and just about everything else I can think of. No matter what I do the grid will restore the previously selected list after the postback to the form. Even if I get the list cleared on a temporary basis it seems to come back when the post back is fully completed.

How do I programatically clear the selected rows when the "RestoreRowSelection="All" option is enabled? In my case the previously selected items no longer exist as valid items to choose from but the internal collection of checked items still lists them. I want that list emptied out but I can't figure out how.
