How to use ASPxClientGridView GetSelectedKeysOnPage and GetVisibleRowsOnPage to manage row deletion on the client side

This example demonstrates how to use ASPxClientGridView.GetSelectedKeysOnPage and ASPxClientGridView.GetVisibleRowsOnPage to prevent a user from deleting all rows on a single grid page (if editing logic requires it).

To do this, you can compare the array length of keys obtained through GetSelectedKeysOnPage (returns keys only on a visible page) and the number of rows on a page obtained through GetVisibleRowsOnPage.
