在tabControl中隐藏和显示TabPages [英] Hiding and Showing TabPages in tabControl

问题描述

我正在尝试根据用户选择显示或隐藏选项卡.如果用户选择性别为男性，则应显示男性"选项卡中的男性表格；如果用户选择女性，则应在下一个选项卡女性"中显示类似的下一个表格

I am trying to show or hide tabpages as per user choice. If user selects gender male then form for male in a tabpage "male" should be displayed and if user selects female then similar next form should be displayed in next tab "female"

我尝试使用

tabControl1.TabPages.Remove(...)

和

tabControl1.TabPages.Add(...)

它添加和删除了标签页，但是这样做也会使我对标签页的控件失去控制...我看不到它们.这是什么问题?

It adds and removes the tabpages but doing so will loose my controls on tabpages too... i can't see them back. what's the problem here?

推荐答案

您可以从TabControl.TabPages集合中删除选项卡页，并将其存储在列表中.例如:

You could remove the tab page from the TabControl.TabPages collection and store it in a list. For example:

    private List<TabPage> hiddenPages = new List<TabPage>();

    private void EnablePage(TabPage page, bool enable) {
        if (enable) {
            tabControl1.TabPages.Add(page);
            hiddenPages.Remove(page);
        }
        else {
            tabControl1.TabPages.Remove(page);
            hiddenPages.Add(page);
        }
    }

    protected override void OnFormClosed(FormClosedEventArgs e) {
        foreach (var page in hiddenPages) page.Dispose();
        base.OnFormClosed(e);
    }
