Hi!

I've been trying the whole evening to programatically add rows to my DataGridView but I can't seem to get it working I tried lots of differents ways but none of them seem to be working.

I get no errors, everything looks fine.

I have a WinForm, I added a DataGridView, bound a DataSource to it (table from a SQL 2008 connection).

The data shows up in it, everything is fine but I want to process the data before showing it, so I want to programatically add rows myself.

Here's what I tried so far:

string[] rowArray = new string[]{ "Test", "Test", "Test" };
dataGridView.Rows.Add(rowArray[0]);
-

dataGridView.Rows.Add();
int newRowIndex = dataGridView.RowCount - 1;
DataGridViewRow newRow = dataGridView.Rows[newRowIndex];

newRow.Cells["PurchaseOrderId"].Value = "Test";
newRow.Cells["SupplierId"].Value = "Test";
newRow.Cells["State"].Value = "Test";
-

DataRow newRow = purchaseOrders.NewRow(); // purchaseOrders = this.purchaseOrderManagerDataSet.PurchaseOrders

newRow["PurchaseOrderId"] = "Test";
newRow["SupplierId"] = "Test";
newRow["State"] = "Test";

dataGridView.Rows.Add(newRow);
None of them adds something to the DataGridView.

Any idea of what I'm doing wrong?

Thanks a lot!
