vb.net DataGridView更新標籤，而打字

Question

我有一個datagridview，我想過濾。

在datagridview上面，我有第二個單行空過濾器datagridview具有相同數量的列。

當用戶輸入其中一個單元格時，我想根據過濾器datagridview的填充單元格過濾主datagridview。

在應用過濾器之前，我想在當前單元格文本仍在編輯時更新標籤。

如何在編輯結束前獲取用戶更改的文本？

解決 - 與c.EditedFormattedValue.ToString

Private Sub dgvFilter_EditingControlShowing(ByVal sender As Object, _ 
    ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) _ 
    Handles dgvFilter.EditingControlShowing 

    Dim tb As TextBox = TryCast(e.Control, TextBox) 

    If (tb IsNot Nothing) Then 
     RemoveHandler tb.KeyUp, AddressOf tb_KeyUp 
     AddHandler tb.KeyUp, AddressOf tb_KeyUp 

     'RemoveHandler tb.KeyDown, AddressOf tb_KeyDown 
     'AddHandler tb.KeyDown, AddressOf tb_KeyDown 
    End If 

End Sub 


Private Sub tb_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) 

    Dim c As DataGridViewCell = dgvFilter.CurrentCell 
    Dim s As String = c.EditedFormattedValue.ToString 
    Dim totalFilter As String 

    lblKeyCode.Text = e.KeyCode 

    'If e.KeyCode <> Keys.Down Then 

    cellName = dgvFilter.Columns(dgvFilter.CurrentCell.ColumnIndex).Name 

    cellFilter = "[" & cellName & "] LIKE '" & s & "%'" 

    'get the filter (other columns plus current column) 
    totalFilter = FilterString(dgvFilter, cellFilter) 
    Me.txtFilter.Text = totalFilter 

    'apply the filter 
    Me.lookupDataTable.DefaultView.RowFilter = totalFilter 
    'Else 
    'dgv.Focus() 
    'End If 

End Sub
