DatagridView KeyUp add New Row Problem

Hi,
i have problem when addnew row at keyup event for datagridview control.
i want to add one row when method addRow() called.

this my code :

vb.net Code:

Public Class Form2
    Dim dt As New DataTable("view")
 
    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        dt.Columns.Add(New DataColumn("Col1"))
        dt.Columns.Add(New DataColumn("Col2"))
        dg.DataMember = "view"
        dg.DataSource = dt
    End Sub
 
    'new rows
    Private Sub btnAddRow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddRow.Click
        addRow()
    End Sub
    Sub addRow()
        Dim dr As DataRow
        dr = dt.NewRow
        dr.Item(0) = ""
        dr.Item(1) = ""
        dt.Rows.Add(dr)
    End Sub
 
    Private Sub dg_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles dg.KeyUp
        If e.KeyData = Keys.Enter Then
            Dim cCol = dg.CurrentCell.ColumnIndex
            If cCol = 1 Then
                addRow()
            End If
            'End Select
        End If
    End Sub
End Class

the problem at dg_KeyUp code, Since more than 1 row created while I want only 1 line only.

thank you

anyone can help?? :)

If your Datagridview is bound to a Datatable, then try the following code in addrow()

vb Code:

Dim row As DataRow = dt.NewRow
row("Col1") = "Name1"
row("Col2") = "Name2"
dt.Rows.Add(row)

thanks for the replay.
what's the difference with my code above

vb Code:

Sub addRow()
        Dim dr As DataRow
        dr = dt.NewRow
        dr.Item(0) = ""
        dr.Item(1) = ""
        dt.Rows.Add(dr)
    End Sub

dr.Item(0) and dr(0) only way of writing it

What exactly do you want to achieve through the KeyUp event ? It would be helpful if you spot it out more clearly. Do you want to generate new rows dynamically as you keep on hitting the Enter key ?

when I press the enter key while in column 1 on the grid I would like for a line just added.
but what happened instead 2 rows straight.

and if I press button btnAddRow can work well rather than using the enter key .

At the moment i was able to come up with this. This code can generate single rows when you hit the Enter key.

Try this :

vb Code:

Private Sub dg_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles dg.KeyDown
 
        If e.KeyCode = Keys.Enter Then
 
            addRow()
 
            e.Handled = True
 
        End If
 
End Sub
