Telerik WinForms Radgriview过滤器布尔值

Question

我正在使用Telerik WinForms RadGridView控件，我已经设置了类似Excel的过滤，一切都很好，但我有一点问题。当我过滤一个布尔字段时，在过滤器弹出窗口中，它们是值：“True”和“False”。是否可以在更加用户友好的方面更改它们，例如“是”和“否”？

要避免链接仅在链接断开时不理想的链接。以下是解决问题的相关代码：

void radGridView1_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
{
    RadListFilterPopup popup = e.FilterPopup as RadListFilterPopup;
    if (popup != null)
    {
        RadTreeView tree = popup.MenuTreeElement.TreeView;
        tree.NodeAdded += new RadTreeView.RadTreeViewEventHandler(tree_NodeAdded);
        popup.PopupClosed += new RadPopupClosedEventHandler(popup_PopupClosed);
    }
}

void popup_PopupClosed(object sender, RadPopupClosedEventArgs args)
{
    RadListFilterPopup popup = sender as RadListFilterPopup;
    popup.MenuTreeElement.TreeView.NodeAdded -= new RadTreeView.RadTreeViewEventHandler(tree_NodeAdded);
}

void tree_NodeAdded(object sender, RadTreeViewEventArgs e)
{
    if (e.Node.Text == "False")
    {
        e.Node.Text = "No";
    }
    else if (e.Node.Text == "True")
    {
        e.Node.Text = "Yes";
    }
}
