I would like to bind different queries for a long set of columns in datagridview that has been set already during the formload, e.g:
With dgvGrid
.Columns(0).Name = "Dept Code"
.Columns(1).Name = "Emp ID"[code]....
there are still more of it. The data needed for those columns is coming from a different table.
So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.
For example, if a table had nothing but names, e.g.
Joe
Sean
Larry
Chris
Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.
