Verify Deleted Data
PROBLEM
I would like to verify that an element does not exist, like after deleting a row from a data grid.
SOLUTION
This is possible with a Wait for ExistsNot verification. Here's an example against this Telerik demo site:
- Drag the first DataGridItem from Pending Orders to Shipped Orders.

- Before deleting the DataGridItem, create the Wait for ExistsNot verification while it still exists.

- Drag the DataGridItem from Shipped Orders to the Recycle Bin.

- Click OK on the Confirm dialog.
- Move the Wait for ExistsNot step to the last position.

- Execute the test.
