I have a client that would like to insert new rows between existing rows in a datagrid. Example: 5 rows in a grid, the user selects row 3 and wants to insert a row between row 2 and the selected row 3. is this possible with the Telerik grid?
As far as I know this functionality is not supported, however
you may consider taking advantage of the drag and drop feature of
RadGrid for ASP.NET AJAX which allows you to move records within the
same grid at a location of your choice (above or below a given item): Grid / Items Drag-and-drop.
