Form Focus Issue

[Fr15ky]

First of all, I am using the .NET 2.0 framework with Visual Studio
2005.

I have two forms. One is a form with a TreeView control on it (used as
a menu - kindof a favorites list) and the other is a form with a
WebBrowser control on it.

The TreeView_Click event fires up the other form with the link passed
to it via the Node. If the user clicks the TreeView and the form is
already open with that link in it, it is supposed to set focus to the
appropriate form. This does occur, but it appears that when the Click
event completes, the form with the TreeView control on it gets the
focus back. So other than the TreeView form, the proper WebBrowser form
is at the front.

How do I get the form with the TreeView to remain behind the properly
selected WebBrowser form?

Any suggestions would be appreciated.

isn't it just me.sendtoback? form inherits from control so this should work.

Fr15ky,

I am not aware how long you are working already with VBNet.

Quiet anoying however logical is that in Net, when you change an item in an
event, it is possible that it triggers its own or another event. (This
happens especially with the combobox, listbox and treeview)

That can change the behaviour. Are you sure that it is not that.

I hope this helps,

Toff,

I will try doing that, I was able to have it work the first time I
click the link by doing a WebBrowserForm. BringToFront,
WebBrowserForm. Activate, and WebBrowserForm. Focus in the WebBrowser
controls _Navigated Event. But once the form has been loaded, this
event no longer runs as I am just setting focus (activating, bringing
to the front) the appropriate WebBrowserForm. In my quick trial,
however, this did not work (or I am not finding the last event that is
causing the Navigator form to get the focus back.

Cor,

Honestly, I am new to .NET. I have only really been working on .NET for
about 2 weeks. It is obviously event oriented, because this problem is
specific to the MouseDown event but the KeyDown event of the TreeView
works properly.

Do you have an event that you believe would work properly for Toff's
suggestion? I would prefer an event that can be tied to the TreeView.

Thanks for the responses and the help.

Fr15Ky,

And you are sure that there (as I wrote) is not any instruction more
triggered that is done in your treeview form?

Did you debug your program?

Cor,

Here is the ONLY code around the navigator:

Private Sub tvwNavigator_Ke yDown(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyEventA rgs) Handles tvwNavigator.Ke yDown
If e.KeyCode = Keys.Enter Then
If Not tvwNavigator.Se lectedNode.Equa ls(Nothing) Then
ProcessNavigato rClick(tvwNavig ator.SelectedNo de)
End If
End If
End Sub

Private Sub tvwNavigator_Mo useDown(ByVal sender As Object, ByVal e
As System.Windows. Forms.MouseEven tArgs) Handles tvwNavigator.Mo useDown
tvwNavigator.Se lectedNode = tvwNavigator.Ge tNodeAt(e.X, e.Y)
ProcessNavigato rClick(tvwNavig ator.SelectedNo de)
End Sub

Other than the above code, the form only has a _Load event that fills
the TreeView, a mnuNavExit_Clic k event that closes the application and
a mnuNavLargeIcon s_Click event that will change the ImageList for the
TreeView.

So I don't know if there is anything else I should check.

FR15Ky,

tvwNavigator.Se lectedNode = tvwNavigator.Ge tNodeAt(e.X, e.Y)

In my idea will this give an action as the form get painted again.

Can you remove it and see what happens?

Cor,

Nope that didn't work and now I have even more problems, because the
SelectedNode is not the right one.

Hi Mark,

Why do you use tvwNavigator.Mo useDown? There is an event called AfterSelect
that fires after a node in a treeview is selected. To get the newly selected
node just query the argument
ByVal e As System.Windows. Forms.TreeViewE ventArgs

of this event for e.Node.

Using mousedown as you have may well return nothing for GetNodeAt(e.X, e.Y)
if the coordinates do not map to a node.

This probably wont solve your initial problem however so can you show us the
code for

ProcessNavigato rClick()

You said above that there is no more code on the treeview form and yet i
dont see any kind of type/instance qualifier for ProcessNavigato rClick() so
i can only assume its Me.ProcessNavig atorClick?
