如何模仿Infragistics UltraWinGrid中的复制粘贴按键？

我正在使用Infragistics UltraWinGrid（Win 9.1版本）。默认行为是允许用户将文本输入到单元格中。当从Excel电子表格复制多个单元格时，只有第一个单元格的数据将被粘贴到UltraWinGrid中。如何模仿Infragistics UltraWinGrid中的复制粘贴按键？

通过将UltraWinGrid单元格设置为不可编辑，可以轻松地更改粘贴多个单元格的行为CellClickAction.CellSelect;不幸的是，当你这样做时，你可能不会在单元格中输入数据。

所以我试图与InitializeLayout，KeyDown和按键响应事件来修改这些设置。

private void ugridQuoteSheet_InitializeLayout(object sender, InitializeLayoutEventArgs e) 
    { 
     e.Layout.Override.AllowMultiCellOperations = AllowMultiCellOperation.All; 
     e.Layout.Override.CellClickAction = CellClickAction.CellSelect; 
    } 

    //Event used to circumvent the control key from choking in 
    //the KeyPress event. This doesn't work btw. 
    private void ugridQuoteSheet_KeyDown(object sender, KeyEventArgs e) 
    { 
     UltraGrid grid = (UltraGrid)sender; 

     if (e.Control == true) 
     { 
      e.SuppressKeyPress = true; 
     } 
    } 

    // This event comes after the KeyDown event. I made a lame attempt to stop 
    // the control button with (e.KeyChar != 22). I lifted some of this from 
    // the Infragistics post: http://forums.infragistics.com/forums/p/23690/86732.aspx#86732 
    private void ugridQuoteSheet_KeyPress(object sender, KeyPressEventArgs e) 
    { 
     UltraGrid grid = (UltraGrid)sender; 
     if ((grid != null) && (grid.ActiveCell != null) && (!grid.ActiveCell.IsInEditMode) && (e.KeyChar != 22)) 
     { 
      grid.PerformAction(UltraGridAction.EnterEditMode); 
      EditorWithText editor = (EditorWithText)grid.ActiveCell.EditorResolved; 
      editor.TextBox.Text = e.KeyChar.ToString(); 
      editor.TextBox.SelectionStart = 1; 
     } 
    } 

    // This puts the grid in CellSelect mode again so I won't edit text. 
    private void ugridQuoteSheet_AfterCellUpdate(object sender, CellEventArgs e) 
    { 
     this.ugridQuoteSheet.DisplayLayout.Override.CellClickAction = CellClickAction.CellSelect; 
    }

我现在可以再次将值输入到单元格中。问题是，当我按[Ctrl] [V]为糊状，在KeyPressEventArgs.KeyChar是22并没有“V”。你可以在ugridQuoteSheet_KeyPress委托中看到我的无用尝试绕过这个问题。事件处理和CellClickAction设置的正确组合允许复制粘贴和键入到UltraWinGrid的单元中？

经过仔细阅读之前提到的帖子（http://forums.infragistics.com/forums/p/23690/86732.aspx#86732 ）后，我已经能够解决这个问题。

这可以所有设置UltraWinGrid.DisplayLayout.Override.CellClickAction = CellClickAction.CellSelect后KeyPress事件内处理;当然在InitializeLayout事件中。

private void ugridQuoteSheet_KeyPress(object sender, KeyPressEventArgs e) 
    { 
     UltraGrid grid = (UltraGrid)sender; 

     if (!Char.IsControl(e.KeyChar) && grid != null && grid.ActiveCell != null && 
      grid.ActiveCell.EditorResolved is EditorWithText && !grid.ActiveCell.IsInEditMode) 
     { 
      grid.PerformAction(UltraGridAction.EnterEditMode); 
      EditorWithText editor = (EditorWithText)grid.ActiveCell.EditorResolved; 
      editor.TextBox.Text = e.KeyChar.ToString(); 
      editor.TextBox.SelectionStart = 1; 
     } 
    }

我不知道如何处理同时按键[ctrl] [v]。该Char.IsControl（e.KeyChar）这里的伎俩。
