A very strange phenomenon -> when I add a new tab, the webBrowser1 control is cut from previous and is transfered to the newly tab created. Why? And how to copy that control on each [new] tab? I want the same control on each new tab I create!

TabPage tb;
private void newTab_Click(object sender, EventArgs e)
{
tb = new TabPage();
tb.Name = "Tab" + (tabControl1.TabCount + 1).ToString();
tb.Text = tb.Name;
tb.Controls.Add(webBrowser1);
tabControl1.TabPages.Add(tb);
}

要开心.

Be happy.

推荐答案

问题在下面的行中

Issue is in the below line

tb.Controls.Add(webBrowser1);

应该通过创建新的webBrowser实例来重写它，并将其添加到tb.Controls中.在您当前的代码中，它正在使用现有的webBrowser实例.这就是为什么您遇到此问题的原因.

It should be rewritten with creation of new webBrowser instance and added in tb.Controls. In your current code, it is using the existing webBrowser instance. That is why you are getting this issue.

// webBrowserNew = new instance of webBrowser
// tb.Controls.Add(webBrowserNew);
