I'd like to be able to select a row in a gridview, then click a button that would insert a new row in the same gridview with the same values as the selected row.
This should be fairly straightforward. It will differ though depending on whether you are using the grid in bound or unbound mode.
In bound mode, you would take the
radGridView1.CurrentRow.DataBoundItem
and then programatically copy each of it's values to a new custom object, data row or whatever your grid is bound to, and add the new one to your datasource.
In unbound mode, much the same, but you would need to loop over columns for the current row, and programatically insert a new row with the same values as the current row.
Hope this helps but let me know if you have any questions
