Question

I am developing a windows form application for a Books Store. In this application have a datagridview to select books for sale. If there are no items available in the stock I need to clear the current row values.So how can I do this. I tried this

dataGridView1.Rows.Clear();

But this clear entire datagridview. But I need to clear only current row when I click ok the message.

You will need to specify the row in the datagrid that you want to delete. You can do this by selecting the "index" of the row which is selected.

dataGrid.Rows[index].Selected = true;

or you could do the following:

dataGrid.SelectedRows.Clear();
foreach(DataGridViewRow row in dataGrid.Rows)
{
    if(YOUR CONDITION)
       row.Selected = true;
}

I always use removeat by first checking to ensure something is selected and then do a removeat while passing the index.

if(dataGridView1.CurrentRow.Index > -1 && !dataGridView1.Rows[dataGridView1.CurrentRow.Index].IsNewRow)
    dataGridView1.Rows.RemoveAt(dataGridView1.CurrentRow.Index);

EDIT: Added a check for IsNewRow in case AllowUsersToAddRows is True which would throw and exception if that was the selected row.

@Kith Make sure you add the second check that I added in my last edit since your datagridview has the NewRow enabled. – Charles May Jun 26 '18 at 11:26
But this still throw an exception if my selected row changed to newRow – Kith Jun 26 '18 at 12:38
