How Do I Get the Selected DataRow in a DataGridView?

I'm not sure how to do it w/o a BindingSource, here is how to do it with one:

var drv = bindingSoure1.Current as DataRowView;
if (drv != null)
  var row = drv.Row as MyRowType;

DataRowView currentDataRowView = (DataRowView)dgv1.CurrentRow.DataBoundItem
DataRow row = currentDataRowView.Row

You should be able to directly cast your selected row into the strongly typed row that was bound to the DataGridView.

It is possible by getting following property:

this.dataGridView.SelectedRows

One obtains a collection of type: DataGridViewSelectedRowCollection. It contains items of type: DataGridViewRow.

Then one can get bounditem with ones own type in following way:

DataGridViewSelectedRowCollection list = this.dataGridViewInventoryRecords.SelectedRows;
MyType selectedItem = (MyType)list[0].DataBoundItem; //[0] ---> first item
