Hi All
i'm getting error with my TreeView Menu(I want to have a button with
ExpandALL and CollapseALL):-
Error:-
'AddressOf' operand must be the name of a method; no parentheses are needed.

I use VB.Net and i changed the C# code from:-
private void ExpandAll()
{
for(int i=0; i < yourTree.Nodes.Count; i++)
{
yourTree.Nodes.Expanded = true;
}
}
TO

Public Sub ExpandAll()
Dim i As Integer
For i = 0 To tvFamilyTree.Nodes.Count - 1 Step i + 1
tvFamilyTree.Nodes(i).Expanded = True
Next
End Sub

And called ExapndAll in page load
And on my ASP.NET page called it like this:-
<asp:Button BorderColor=#009966 Runat=server
OnClick="ExpandAll()"></asp:Button>

Can u telling me what 'm doing wrong!!
Thx

Click to expand...


I have no idea, except that the VB code does not match the c# code. The VB
equivilent of that snippet is:

Public Sub ExpandAll()
For i As Integer = 0 To tvFamilyTree.Nodes.Count - 1
tvFamilyTree.Nodes(i).Expanded = True
Next
End Sub

Hi David,
Thx for the snippet.I tried it but still giving the error!!
The exact error is :-
AddressOf' operand must be the name of a method; no parentheses are needed.
AddHandler __ctrl.Click, AddressOf Me.ExpandAll()
Any help!

Hi Patrcik,
Modify the line of code
<asp:Button BorderColor=#009966 Runat=server
OnClick="ExpandAll()"></asp:Button>
to
<asp:Button BorderColor=#009966 Runat=server
OnClick="ExpandAll"></asp:Button> and check.
You dont need to give a parenthesis here.

Hi Patrick,
The ExpandAll method shoulf have the same signature as a delegate so the
ExpandAll should be like
Public Sub ExpandAll(Byval sender As Object, Byval e As System.EventArgs)

Hi Patrick,
I am not sure if this is the best way to do it but you can do it this way.
In the Page_Init method keep the following code
If Not Page.IsPostBack Then ''If you dont want to call the method during
postbacks
AddHandler Me.Load, AddressOf ExpandAll
End If
Now you dont need to call the ExpandAll on the page Load.

Thx for the code ...But still doesn't work arg!!!!!!!!
But i forgot to tell u that i'm using the webcontrol TreeView and loading

Should that be able to work by calling ExpandALL because i don't know why it
doesn't work!

Hi,

Why all this overhead - attaching to the Init event, attaching another
method to the Load event? He'd better call it directly from Page_Load:

Private Sub Page_Load(sender As Object, e As EventArgs) _
Handles MyBase.Load
'Put user code to initialize the page here
ExpandAll(Nothing, EventArgs.Empty)
End Sub

Hope this helps

Hi Martin,
Thanks for the inputs.
If you see the last line of my message i asked not to call the ExpandAll in
the page load again. But its a really valid point. We can call
ExpandAll(nothing, eventargs.empty).
Thanks again

Hi,

Why all this overhead - attaching to the Init event, attaching another
method to the Load event? He'd better call it directly from Page_Load:

Private Sub Page_Load(sender As Object, e As EventArgs) _
Handles MyBase.Load
'Put user code to initialize the page here
ExpandAll(Nothing, EventArgs.Empty)
End Sub

Hope this helps

Hi Patrick,
I am not sure if this is the best way to do it but you can do it this way.
In the Page_Init method keep the following code
If Not Page.IsPostBack Then ''If you dont want to call the method during
postbacks
AddHandler Me.Load, AddressOf ExpandAll
End If
Now you dont need to call the ExpandAll on the page Load.
HTH
srini
Click to expand...
parameter
e)
Click to expand...
as
delegate
Click to expand...
button
with
Click to expand...
parentheses
are needed.
I use VB.Net and i changed the C# code from:-
private void ExpandAll()
{
for(int i=0; i < yourTree.Nodes.Count; i++)
{
yourTree.Nodes.Expanded = true;
}
}
TO

Public Sub ExpandAll()
Dim i As Integer
For i = 0 To tvFamilyTree.Nodes.Count - 1 Step i + 1
tvFamilyTree.Nodes(i).Expanded = True
Next
End Sub

And called ExapndAll in page load
And on my ASP.NET page called it like this:-
<asp:Button BorderColor=#009966 Runat=server
OnClick="ExpandAll()"></asp:Button>

Can u telling me what 'm doing wrong!!

Hi Martin,
Thanks for the inputs.
If you see the last line of my message i asked not to call the ExpandAll in
the page load again. But its a really valid point. We can call
ExpandAll(nothing, eventargs.empty).
Thanks again

Hi Srini,
I added
Public Sub ExpandAll(Byval sender As Object, Byval e As System.EventArgs)

But in my Page_load:-
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
ExpandAll()
End Sub
The Expand() needs some argument!!(Argument not specified for
Click to expand...
parameter
e)
Any ideas
VS.NET marks it as an error


:

Hi Patrick,
The ExpandAll method shoulf have the same signature as a delegate
Click to expand...
so
the
ExpandAll should be like
Public Sub ExpandAll(Byval sender As Object, Byval e As System.EventArgs)
HTH
srini
:

Thx srini changed it but now i still get the error:-

Method 'Public Sub ExpandAll()' does not have the same signature
Click to expand...
as
delegate
'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'.

Code below:-
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
' ExpandAll()
End Sub

Public Sub ExpandAll()
For i As Integer = 0 To tvFamilyTree.Nodes.Count - 1
tvFamilyTree.Nodes(i).Expanded = True
Next
End Sub

ASP.NET
---------
<asp:Button BorderColor=#009966 Runat=server OnClick="ExpandAll"
ID="Button1"></asp:Button>

Anu idea what i'm doing wrong!!

:

Hi Patrcik,
Modify the line of code
<asp:Button BorderColor=#009966 Runat=server
OnClick="ExpandAll()"></asp:Button>
to
<asp:Button BorderColor=#009966 Runat=server
OnClick="ExpandAll"></asp:Button> and check.
You dont need to give a parenthesis here.
