浏览器前进后退的判断

你可以在WebBrowser的DocumentTitleChanged事件里判断是否能前进后退
Back为上页 Next为下页

void webBrowser1_DocumentTitleChanged(object sender, EventArgs e)
{
if (webBrowser1.CanGoBack == false)
{
Back.Enabled = false;
}
else
{
Back.Enabled = true;
}
if (webBrowser1.CanGoForward == false)
{
Next.Enabled = false;
}
else
{
Next.Enabled = true;
}
}
