Hello,

how can delete those rows in the DataTable, which I have selected in the DataGridView ?
private void moveArticlesToFilterButton_Click(object sender, EventArgs e)
        {
            foreach (DataGridViewRow row in articlesDataGridView.SelectedRows)
            { 
                articlesChoiceDataTable.Rows.Add(row.Cells[2].Value.ToString(),
                                                 row.Cells[3].Value.ToString(),
                                                 row.Cells[4].Value.ToString(),
                                                 row.Cells[5].Value.ToString(),
                                                 row.Cells[6].Value.ToString(),
                                                 row.Cells[7].Value.ToString());
 
                articlesDataTable.Rows.Remove(row); // does not work
            }
             
        }

Hi,

The item can't be removed from collecting while iterating within it.

Two ways to resolve this issue are:
1. Create temporary collection of items to be removed.  Fill temporary collection with items to be removed from original collection.  Iterate through temporary collection to remove items from original collection.
2. Use for loop.
private void moveArticlesToFilterButton_Click(object sender, EventArgs e)
        {
            for (int i = articlesDataGridView.SelectedRows.Count - 1; i <= 0; i--)
            {             articlesChoiceDataTable.Rows.Add(articlesDataGridView.SelectedRows[i].Cells[2].Value.ToString(),
     articlesDataGridView.SelectedRows[i].Cells[3].Value.ToString(),
     articlesDataGridView.SelectedRows[i].Cells[4].Value.ToString(),
     articlesDataGridView.SelectedRows[i].Cells[5].Value.ToString(),
     articlesDataGridView.SelectedRows[i].Cells[6].Value.ToString(),
     articlesDataGridView.SelectedRows[i].Cells[7].Value.ToString());
     articlesDataGridView.SelectedRows.RemoveAt(i); 
            }
             
        }
