在datagridview中删除行的列表

Question

I got a DataGridView which just allows user to delete rows (with no direct editing or adding on DataGridView). I will update my database information whenever user deletes rows on DataGridView (there is no binding among DB and gridview).

I have no problem to have deleting row when user is deleting only one row using DeletingRow event like below:

private void dataGridView1_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e)
{
    DataGridViewRow row = e.Row;     //only single row
}

However i could not capture list of all rows when user selects multiple rows and delete them. Above event only called once for first row only. In order to handle this case i did set dataGridView1.MultiSelect = false; however this is a workaround!
So how can i have list of all selected rows which user is deleting, currently?

Answer 1

All selected rows will be available at dataGridView1.SelectedRows
so you can do something like:

    void dataGridView1_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e)
    {
        foreach (DataGridViewRow row in this.dataGridView1.SelectedRows)
        {
            this.HandleRowDeletion(row);
        }
    }

Answer 2

Use dataGridView1.SelectedRows to get a collection ( DataGridViewRowCollection type) that contains all the rows selected. Same works for columns ( dataGridView1.SelectedColumns ) and cells ( dataGridView1.SelectedCells ).
