Problem with adding columns to DataGrid [Resolved]

[albertlse]

Currently my DataGrid has 3 columns. These 3 columns are from a DataSet which refer to a database.
I want to add 1 extra column to DataGrid, so that user can check/tick on it to indicate a row is selected.
can i do so?

actually i read through the MSDN help file
ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.1033/vbcon/html/vbtskcreatingcustomcolumntypesindatagrid.htm

i follow exactly this MSDN help file but cannot get what I want.

please guide me thank you.

To get selected row , do this :

MsgBox("Row number is " & DataGrid1.CurrentCell.RowNumber)

[Pirate]

I've just realized , this is easier and clearer :

Private Sub DataGrid1_CurrentCellChanged(ByVal sender As 
Object, ByVal e As System.EventArgs) Handles DataGrid1.CurrentCellChanged
        'This method : 
        MsgBox("Row number is " & DataGrid1.CurrentCell.RowNumber)
 
        'Or this method : 
        'MsgBox(DataGrid1.CurrentRowIndex())
    End Sub

visual basic code:--------------------------------------------------------------------------------
Private Sub DataGrid1_CurrentCellChanged(ByVal sender As
Object, ByVal e As System.EventArgs) Handles DataGrid1.CurrentCellChanged
'This method :
MsgBox("Row number is " & DataGrid1.CurrentCell.RowNumber)

'Or this method :
'MsgBox(DataGrid1.CurrentRowIndex())
End Sub

Pirate,
Actually what I want to do is like this:
I load all employees' data in the dataset.
The DataGrid is binded to the dataset. So it will display all employee's data.
I will like to make user select those desired rows.
Then the PrintDocument will print those selected rows.

According to your code, can it do, or can it be modify to suit what I want?

Please guide, or suggest. thank you.

That code only shows you which row was selected or click by the user . It's part of what you been asking I believe .

Pirate, you are right. that's part of what i been asking.
So if I selected multiple rows (by holding Shift/Ctrl key and click on the rows that I wanted to be selected), what function can I call to retrieve all the selected rows' number?
Please guide, thank you.

Try this :

Private Sub DataGrid1_CurrentCellChanged(ByVal sender As 
Object, ByVal e As System.EventArgs) Handles DataGrid1.CurrentCellChanged
 
        Dim i As Integer
 
        For i = 0 To DataGrid1.VisibleRowCount - 1
            If DataGrid1.IsSelected(i) = True Then
                MsgBox(DataGrid1.Item(i, 0))
            End If
        Next
 
    End Sub
