Problem with (new) datagrid / dataset

I have a dataset in a Datagrid that is not working the way that is should. At one time it was fine but somehow I messed it up

When I first load the dataset this is what I get

Then (Once Clicked)

And finally (After Second Click)

It used to open up with the full grid loaded the first time. Here is the code I am using. Any ideas what went wrong and how to fix it?

VB Code:

Private Sub RefillDataGrid()
 
        Dim cnn As New OleDb.OleDbConnection( _
               "Provider=Microsoft.Jet.OLEDB.4.0;" & _
               "Data Source=" & strDataBaseName)
        Dim cmd As New OleDb.OleDbCommand
        cnn.Open()
        cmd.Connection = cnn
 
        Dim da As New OleDb.OleDbDataAdapter
        Dim DsPayroll1 As New DataSet
        Try
            cmd = cnn.CreateCommand
 
            cmd.CommandText = "Select * From TimeGR"
 
            '***********************************************
            '"Select * From TimeGR Where EmployeeNumber='" & _
            '(txtEmp.Text) & "'"
            '***********************************************
 
            da.SelectCommand = cmd
            da.Fill(DsPayroll1, "TimeGR")
            DataGrid1.DataSource = DsPayroll1
        Catch ex As Exception
            MsgBox("Error: " & ex.Source & ": " & ex.Message, _
            MsgBoxStyle.OKCancel, "Populate Datagrid")
        End Try
        cnn.Close()

Thanks

You have to bind directly to the datatable. Try this

VB Code:

da.Fill(DsPayroll1, "TimeGR")
DataGrid1.DataSource = DsPayroll1.Tables("TimeGR")

That did the trick. Thank you. By the way what is the proper way to clear the datagrid so that I can refresh the content (reload dataset) for the user?

Basicaly I need to refresh the content in the datagrid as the user adds and or deletes records from text boxes in the grid.

I know how to do the add and delete but I am not sure how to get the results back to user.

Just re-bind the dataset.
