Question

I have a DataGridView that is bound to a DataSet and I allow someone to remove a row from the table and I remove the row from the set. My code looks like this:

ds.Tables(0).Rows(dgCourseList.SelectedRows(0).Index).Delete()

My problem I found is if the grid gets sorted the index of the rows no longer corresponds to the indexes in the DataSet. As a result the wrong rows get removed from the set.

Can I solve this problem with maybe having to sort the DataSet on some sort event of the DataGridView?

Answer 1

I haven’t tested this but try the following assuming you have the DataKeys setup properly:

ds.Tables(0).Rows.Remove(ds.Tables(0).Rows.Find(dgCourseList.DataKeys(dg.SelectedIndex)))

EDIT: Based on you specifying that you are using a DataGridView which is a winforms app (I was assuming a webforms app) then you could try:

ds.Tables(0).Rows.Remove(ds.Tables(0).Rows.Find(DirectCast(dg.SelectedRows(0).DataBoundItem, DataRowView).Row))

EDIT 2: Updated because I think the cast was wrong… still untested though.
