Issue Description

UX issue. The confirmation dialog to delete selected rows, to delete all rows and to delete the whole class require to enter the class name. All 3 dialogs look similar. The issue is that the dialogs may be mistaken for each other. Also the buttons in the menu to perform these actions are next to each other.

Related issue: #2239

Approach

Updated RowDeleteDialog component, to show different confirmation text based on row selection(props.selection).

selection length >= 10 --> confirmationText = "delete selected" selected all --> confirmationText = "delete all"

Note: for deleting whole class there is different dialog component(No changes there).
