Datagrid- Text box Focus Problem

[SantoshKomarraju]

Help! i am using data grid control to display dynamic data in a windows application.
To edit data in data grid cell i place text box dynamically .
my prob is when i select edit cell using tab control focus to that cell is not working.
when i use mouse prob is solve.but using mouse in my application is not a user friendly.
i write the bellow code

Private Sub data gridname _CurrentCellChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles dgditem.CurrentCellChanged

If dgditem.CurrentCell.ColumnNumber = 4 Then
TextBox.Left = dgditem.Left + dgditem.GetCurrentCellBounds.Left
TextBox.Top = dgditem.Top + dgditem.GetCurrentCellBounds.Top
TextBox.Width = dgditem.GetCurrentCellBounds.Width
TextBox.Text = dgditem.Item(dgditem.CurrentCell.RowNumber, dgditem.CurrentCell.ColumnNumber)
TextBox.Visible = True
TextBox.BringToFront()
TextBox.Select()
TextBox.Focus()

Thanks
