private void gvLampConfig_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e)
{
  GridView _view = sender as GridView;
  if (_view.FocusedColumn.Name == "colSavePowerGp1")//當列等于colSavePowerGp1
  {
 string _type = _view.GetRowCellDisplayText(gvLampConfig.FocusedRowHandle, "OptStatusText_gp1");
 if (!_type.Equals("節(jié)能"))//當列OptStatusText_gp1的列值不等于OptStatusText_gp1
 {
   e.Cancel = true;
   ShowToolTip(toolTipController, "提示", "當是【調光狀態(tài)】是節(jié)能模式情況，可以設置該值!");
 }
  }
}
public static void ShowToolTip(ToolTipController toolTip, string title, string content)
{
  Point _mousePoint = Control.MousePosition;
  toolTip.ShowHint(content, title, _mousePoint);
}

代碼運行效果如下：

為了調高代碼復用性，方便后續(xù)使用，可以這樣子封裝一下：

/// <summary>
/// 設置RepositoryItem是否可編輯
/// 說明：
/// 在ShowingEditor事件中使用
/// </summary>
/// <param name="view">GridView</param>
/// <param name="focusedColumnName">需要設置的列名稱</param>
/// <param name="conditonHanlder">判斷委托</param>
/// <param name="toolTip">ToolTipController</param>
/// <param name="title">當條件委托成立的時候提示標題</param>
/// <param name="content">當條件委托成立的時候提示內容</param>
/// <param name="e">CancelEventArgs</param>
private void CustomShowingEditorWithToolTip(GridView view, string focusedColumnName, Func<object, bool> conditonHanlder, ToolTipController toolTip, string title, string content, CancelEventArgs e)
{
  if (view.FocusedColumn.Name.Equals(focusedColumnName))
  {
 if (conditonHanlder(view.GetFocusedRow()))
 {
   e.Cancel = true;
   Point _mousePoint = Control.MousePosition;
   toolTip.ShowHint(content, title, _mousePoint);
 }
  }
}

代碼使用如下：

private void gvLampConfig_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e)
{
  GridView _view = sender as GridView;
  CustomShowingEditorWithToolTip(_view, "colSavePowerGp1", arg => ((LampSelfRunCfgParamter)arg).OptStatusText_gp1 != "節(jié)能", toolTipController, "提示", "當是【調光狀態(tài)】是節(jié)能模式情況，可以設置該值!", e);
}

希望本文所示代碼能對大家有所幫助！
