Chris,
Can you show an example? What is it databound to? Is the
AllowUserToAddRows property set to true on the DataGridView? Or are you
getting an error when trying to do this programattically?

AllowUserToAddRows = true I am trying to add them programatically. I see an error that you cannot when the datagridview is bound to a dataset. If the edit a row, then a new row appears automatically at the last row. I need to "insert" a row before or after a selected row then add data to it.

Try adding a row to the DataTable, and not the DataGridView Try something like: DataRow myNewRow; myNewRow = myDataSet.myDataTable.NewRow(); // assuming typed dataset myNewRow[0] = ... myDataSet.myDataTable.Rows.Add(myNewRow);

Forgot too... when you add a row, it adds to the end. Do you have a column that you can use for an index or sort on? I'd say if there is, you may be able to add the row, set the key column, and then refresh the datagridview? To borrow a very old method used in the old days of BASIC... you could have each row with a column having a sequence number, say 10, 20, 30, 40... and when you add a row, you could insert a row say at 15. You may have to "re-align" the rows on the fly if you start adding a lot of rows however. I haven't tried it, but this almost seems like a task for a Doubly-Linked list.

3.dataGridView.Rows.Count and datagridview.RowCount
Hello all, I want to display the number of items in an datagridview. I use this one datagridview for different datasets. The datagridview.Rowcount works fine for the most of the dataset. But there is one dataset which has more items than the others and the Rowcount wont work. The result is all the time 0, but it should be something like 85. // Datsource this.dataGridView1.DataSource = this.REMINDERBindingSource; this.v_REMINDERTableAdapter.Fill(this.subnr.REMINDER); // Display number of items lbl_row.Text = dataGridView1.RowCount.ToString(); MessageBox.Show(this, dataGridView1.Rows.Count.ToString()); Has somebody an Idea? Thanks in advance. Greets SePp
