如何从winForm c＃中的datagridview获取用户输入的数据？

Question

I have an empty datagridview which I am using to collect data from the user. When the user moves onto the next tab I want to save the data entered. But according to the datagridview there is no rows. Yet when I go back to that tab the data still there.

I've tried this..

int i_rows = dataGridView1.RowCount;
for (int i = 0; i < i_rows; i++)
{
  var colValue = dataGridView1.Rows[i].Cells[0].Value;
}

and this..

foreach (DataRow row in dataGridView1.Rows)
{
  var colValue = dataGridView1.Rows[i].Cells[0].Value;
}

And I added an event to when UserAddRow which is triggered but still no rows in the dataGridView.

Answer 1

Have you tried the "CellValueChanged" event instead of "UserAddRow" event.

The UserAddRow event is triggered when the last row goes into edit mode. At this point the cells in the last row hasn't registered any value, the edited cell register the value when the cell value changed event is triggered. If you use the "CellValuechanged" event it is most likely that you will get the value of the cell.
