    (VS 2010) DataGridView reading from cell


    I'm faced with a problem that I cannot find a solution to.

    My DGV is binded to an access db. It contains 2 columns (Date, Time), which are in the DateTime format. Everything else is a String. Now, on my CellValidating event, I go through each cell when creating a new row. What I made the program do is copy the date cell, and copy it into the time cell, which is before the time cell. As you can see on the following picture, the time cell is wrong... It should be as "11/07/2012 12:00 AM" instead of "01/01/0001 12:00 AM". Can anyone guide me in the right direction?

    PHP Code:
        Private Sub TimeLogDataGridView_CellValidating(ByVal sender As ObjectByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgsHandles TimeLogDataGridView.CellValidating

            Dim Cell 
    As DataGridViewCell TimeLogDataGridView.Item(e.ColumnIndexe.RowIndex)

    ' cell validation, to check if previous entry is OK

            If Cell.IsInEditMode = True Then
                Select Case TimeLogDataGridView.Columns(e.ColumnIndex).DataPropertyName

                    Case "Description"
                        If e.FormattedValue = "" Then
                            MsgBox("Enter a description.")
                            e.Cancel = True
                            Cell.Selected = True
                            e.Cancel = False
                        End If

                    Case "currentDate"
                        If e.FormattedValue = "" Then
                            MsgBox("Enter a date.")
                            e.Cancel = True
                            Cell.Selected = True
                            e.Cancel = False

                            Me.TimeLogDataGridView.Columns(2).DefaultCellStyle.Format = "g"
    this is for testing
    .TimeLogDataGridView.CurrentRow.Cells(3).Value TimeLogDataGridView.CurrentRow.Cells(0).Value.ToString
    ' this is screwed up
                            Me.TimeLogDataGridView.CurrentRow.Cells(2).Value = TimeLogDataGridView.CurrentRow.Cells(1).Value.ToString
    testing 2
    .Label4.Text TimeLogDataGridView.CurrentRow.Cells(2).Value.ToString

    If e.FormattedValue <> "" Then
    If IsDate(e.FormattedValue) = True Then
    .Cancel False
    MsgBox("Enter a time.")
    e.Cancel True
    .Selected True
    End If
    End Select
    End Sub

    Because you have a TIME/DATE field. Use # # around it in the format it expects. ddd. and the remainder as a fraction.
