how can i locate a webbrowser control

david seinfeild

im using this code here

to find a webbroswer newly created
but it wont find any of my broswer
not even my static one called
webbroswer1

on the other end it will find any other control
and dispose of it properly

how can i find a webbroswer by its name and remove it

heres my code

foreach (var c in this.Controls) { if (c is Control) { var x = (Control)c; if (x.Name == dispose) {
MessageBox.Show("this works");
x.Dispose(); break; }
else { bobby, this doesnt work ); break; }

} }

thx you very much for ur help
it helped me better understand the c# language

heres my final code

if (tabControl1.Visible)
{

tabControl1.Visible = false;

foreach (TabPage page in tabControl1.TabPages)
{
for (int i = page.Controls.Count - 1; i >= 0; i--)
{
Control c = page.Controls[i];
if (c is WebBrowser)
{
if (c.Name == "webBrowser1")
{

tabPage1 = page;
}

else
{
page.Controls.RemoveAt(i);
c.Dispose();
}
}
}
}

for (int i = tabControl1.TabPages.Count - 1; i >= 0; i--)
{
TabPage page = tabControl1.TabPages[i];
if (page != tabPage1)
{
tabControl1.TabPages.RemoveAt(i);
page.Dispose();
}
}

webBrowser1.Navigate("");
}

i put the web broswer new url at the bottom
because when i clear the tabs
it auto select the tab one at the end
and i got it to go to a url automaticly when its selected

finding elements by name is a very usefull thing
but turns out to be extrmly tricky in the context
that im using it into

after some tweak up in my app it works perferctly
i will be using the same code to close tabs individualy aswell
when i figure out how to ad a close button to the tabs

thx again for ur help

OK, this code should achieve that:

// first find the tabpage where the web browser control is located
TabPage wbTabPage = null;

foreach (TabPage page in tabControl1.TabPages)
{
for (int i = page.Controls.Count - 1; i >= 0; i--)
{
Control c = page.Controls[i];
if (c is WebBrowser)
{
if (c.Name == "webBrowser1")
{
((WebBrowser)c).Url = new Uri(@"http://www.google.com");
wbTabPage = page;
}
else
{
page.Controls.RemoveAt(i);
c.Dispose();
}
}
}
}

// now remove all tabpages except that one
for (int i = tabControl1.TabPages.Count - 1; i >= 0; i--)
{
TabPage page = tabControl1.TabPages[i];
if (page != wbTabPage)
{
tabControl1.TabPages.RemoveAt(i);
page.Dispose();
}
}

Sorry, I didn't quite follow that.

Are you saying that you want to dispose of all tabpages except the one on which the webbrowser control is located?

and if i wanted to use the same things but for the tab since
i tried to just go with tabControl1.TabPages.Clear();
but it keeps giving me an error about a missing instance

To do that, I'd try this code:

foreach (TabPage page in tabControl1.TabPages)
{
for(int i = page.Controls.Count - 1; i >= 0; i--)
{
Control c = page.Controls[i];
if (c is WebBrowser)
{
if (c.Name == "webBrowser1")
{
((WebBrowser)c).Url = newUri(@"http://www.google.com");
}
else
{
page.Controls.RenoveAt(i);
c.Dispose();
}
}
}
}

If you have more than one web browser control and you're looking for one named webBrowser1 say, then you can do:

if (c is WebBrowser && c.Name == "webBrowser1") ((WebBrowser)c).Url = newUri(@"http://www.google.com");

If you just want to find the webbrowser control and change its url, try something like this:

foreach (TabPage page in tabControl1.TabPages)
{
foreach (Control c in page.Controls)
{
if (c is WebBrowser) ((WebBrowser)c).Url = newUri(@"http://www.google.com");
}
}

ive gotten it to work using this code

foreach (var c in this.tabControl1.Controls)
{
if (c is Control)
{
var s = (Control)c;

string dispose = tabControl1.SelectedTab.Name.ToString();
if (s.Name == (dispose))
{
s.Dispose();
break;

}

else
{

}

}
}

the thing is i would love to change the url of the webbroswer in that specific tab
but since its in that tab i cant find it just like i couldnt find that tab at first
anyway to acces that newly created webbrowswer in that tab using that code

Try this method which should recursively remove all controls from the form whether they're contained in the form itself, a tab control or any other container:

private void DisposeControls(Control container)
{
for (int i = container.Controls.Count - 1; i >= 0; i--)
{
Control c = container.Controls[i];
if (c.HasChildren) DisposeControls(c);
container.Controls.RemoveAt(i);
c.Dispose();
}
}

You'd start the ball rolling with:

DisposeControls(this);

thx for ur answer the broswer is added dynamicly into a tab of a tab control

Are you sure that you've added the webbrowser controls directly to the form and not to some other container such as a panel?

If you've added them to a panel, then you will need to iterate through the panel's Controls collection to find them.
