I think this format will work (doesn't matter which Table you use)

Label1.Text = DataSet.TableNa me.Rows.Count

Thanks Bruce, but your code with return the row count of Datatable not the
DataGrid. I need the row count for DataGrid.

I know you have the answer for this too :)

Everything you can bind the grid to, a collection, datatable, dataview, and
even dataset, will have something that's enumerable and can be counted...it
depends what you are binding to.

DataTable.Rows. Count should work as Mr. B mentioned unless you are binding
to something else. What is the grid bound to? If a DataView, then
Dataview.rows.c ount. If a strongly typed collection then
Collection.Item s.Count.

Everything you can bind the grid to, a collection, datatable,

dataview,

and

even dataset, will have something that's enumerable and can be

counted...it

depends what you are binding to.

DataTable.Rows. Count should work as Mr. B mentioned unless you are binding to something else. What is the grid bound to? If a DataView, then
Dataview.rows.c ount. If a strongly typed collection then
Collection.Item s.Count.
