How to delete selected rows from a DataGridView?

Question

I have a DataGridView and a Button. If rows are selected I want to delete them by clicking the button. I tried a couple of commands like RemoveAt, SelectedRows etc., but nothing did work. How can I solve that?

I tried something like:

 if (dataGridView2.SelectedRows.Count > 0)
        {

                DataGridViewSelectedRowCollection rows =   dataGridView2.SelectedRows;
                dataGridView2.Rows.RemoveAt(rows);

        } 

but the RemoveAt method does only accept integers. Before I tried it with Selected Cells but then he delets all rows because there is always a cell selected.

Solution 1

If you just want to remove the selected rows from the DataGridView this should do it:

foreach (DataGridViewRow row  in yourDataGridView.SelectedRows)
{
     yourDataGridView.Rows.RemoveAt(row.Index);
}

Your code didn't work because you've used RemoveAt(rows) but RemoveAt accepts only the index of the row which you want to remove. You are passing a DataGridViewSelectedRowCollection to it. You can get the index of a row via DataGridViewRow.Index as shown above.

Solution 2

if you are using a list of model, following code could help:

 foreach (DataGridViewRow row in dataGridViewX.SelectedRows)
            {
                var val = (int)row.Cells[0].Value;
                Products.Remove(Products.Find(d => d.ProductId == val));
            }
            dataGridViewX.DataSource = null;
            dataGridViewX.DataSource = Products;
