How to assign row variable to be able to delete it . . .

My DataGridView is bound by DataTable (csvData). Since the grid mirrors the table, I'm thinking . . . this.DataGridView1.SelectedRows.Count would be the same row of the table. But how do I assign that selected row to the row (DataRow) of the table so I can delete it?

private void DeleteRowButton_Click(object sender, EventArgs e)
        {

            if (this.DataGridView1.SelectedRows.Count > 0 &&
           this.DataGridView1.SelectedRows[0].Index !=
           this.DataGridView1.Rows.Count - 1)

            {

              //  DataRowCollection rowCollection = csvData.Rows.Count();  ???
              //rowCollection.Remove();  ???? no help

                DataRow row;
                row.Delete();  // row not assigned ?

                
             }
          }

Debug and look at the Datasource, to see its structure, and properties.
You may need to get rows by indexed reference.

Try this..

C#

private void button1_Click(object sender, EventArgs e)
        {
           // foreach (DataGridViewRow row in dataGridView1.SelectedRows) // for row selection
            foreach (DataGridViewCell cell in dataGridView1.SelectedCells)
            {
                var rowIndex = cell.RowIndex;
                dataTable.Rows[rowIndex].Delete();
                dataTable.AcceptChanges();

            }
        }</pre>

Assuming your DataSource is accessible inside that event, and assuming the index in your code really points to the index of the DataRow on your DataSource, you can try doing the following:

C#

int index = this.DataGridView1.SelectedRows[0].Index;
yourDataSource.Rows[index].Delete();
yourDataSource.AcceptChanges();
