Hi,

Does mmDataGrid.GetSelectedRows empty its rows when a new single row is selected in a datagrid? I ask because I am getting more than one row in the 'selected rows table' returned from GetSelectedRows after I have selected and deselected a few rows in an mmDataGrid.

To reproduce
--------------------------
1. Select a row in a mmDataGrid.
2. Check the rowcount of mmDataGrid.GetSelectedRows().Tables[0].Rows.Count
3. Select a different row
4. Again, check the rowcount of mmDataGrid.GetSelectedRows().Tables[0].Rows.Count

Thanks in advance,

Andrew

UPDATE : After a little more research I can almost answer my own question :

Looks like mmDataGrid.SelectedRows.Clear is only performed if the mmDataGrid is NOT MultiSelect and you click on the header (see mmDataGrid.cs Method OnMouseDown() LOC 1068 to 1107).

Reproduce (If you have created the Order System CSharp project from the MM Net Development Guide) :
-------------------------------------------------------------------------------------------------------------------------

1. Set a Label on the CustomerOrdersForm
2. In the grdOrders mmDataGrid's onClick event, set the following code :

StringBuilder sb = new StringBuilder();
foreach(object obj in this.grdOrders.SelectedRows)
{
sb.Append(obj.ToString() + " ");
}
this.label1.Text = sb.ToString();

3. Enter "FRANS" in the customerID picker and hit TAB.
4. Randomly select rows in the orders datagrid and see what the label says.

The expected behavior (at least for me) is that the label will contain the index of the currently selected row(s). When I do this test then the index numbers are not reset each time I chose another row. Multiple select also seems to not yeld the correct index numbers for the currently selected rows.

Sincerely,

Andrew
