If you load your DataGridView with a parameter, you can send an empty parameter to it. This will clear your DataGridView without having to set its DataSet to null.

For example, I load my DataGridView with a Code, when I fill a TextBox.

this.dataTable1TableAdapter.Fill(this.ds_MyDataSet.DataTable1, TextBox1.Text);

If I want to clear its content, then

this.dataTable1TableAdapter.Fill(this.ds_MyDataSet.DataTable1, "");
