Read my reply, his code won't really work. You need a recursive function, and you definately do not need to do all that ugly casting.

Wow.

You're on the right track, and yet so far from it. The base class, Control, has the enabled property. The casting you're doing is totally superfluous, and makes the code messy.

Also, don't use 'is' and then cast. Use 'as' and use the result.

finally, the method needs to be recursive for it to work across the page.

Something Like this...

Private Sub DisableControls(ByVal c As Control)
   If TypeOf c Is WebControl Then
      CType(c, WebControl).Enabled = False
   End If
   For Each child As Control In c.Controls
      DisableControls(child)
   Next
End Sub

Put all the controls inside a container control(panel) and pass the Container Control as a parameter to this function. This will Disable all the server controls that is inside the Container Control.

Private Sub DisableControls(ByVal c As Control, ByVal status As Boolean)
    For Each child As Control In c.Controls
        If TypeOf c Is WebControl Then
           CType(c, WebControl).Enabled = status
        End If
    Next
End Sub

What on earth is your problem ? You've asked this four times now, and you have got more than four answers. If you're incapable of understanding the answers, reply to the people who have answered you. What you're doing is plain rude. The answers will not change, no matter how often you ask.

Tell me one thing paren1 and parent2 are predefine node or it create dynamically

When you add any node then check parent node of the node: if it is Root node then allow to add other deny.
Like:

Root
parent1
child1
parent2

suppose if user want to add node in child1 then check parent node of the child1 that is parent1 not it Root. so it will deny it.

if user want to add node in parent1 then check parent node of parent1 is Root that is Root so it will be allow.

Hi
This is beacuse of windows can't verify the activex object which you have, once you make your activex control a signed component, the IE will install your component automatically, and you can fix this. i have got Lpktool.exe from google, that you can use to convert your activex object a signed component...(you must have the source code with you..!)

Hi All,

I am having a datatable which has data as parent child relation. The problem I am facing is explain below with the example.

Ex:
ChildID Description ParentID
A Desc1 NULL
B Desc2 A
C Desc3 A
D Desc4 A

It shows

A
B --| Hidden under Parent A
C |
D ---
B Again Child Element is shown.
C
D

And I want the display as:

A
B --| Hidden under Parent A
C |
D ---

Please help me with this.

Thanks....

Not sure exactly, but I would say a Repeater will solve your problem, because it gives you the most control over your generated HTML. Nested repeaters may be required, I'm not sure, you've not explained it well enough for me to follow fully.

Thanks for the reply. Actually I am using javascript to build this tree and for building I am doing the following as I haveget data from Database:

DataTable dtFinal = cf.Return_DataTable("EXECUTE getAllData 719, 1, 0, 0", connectionString);

In dtFinal I get the records as

ChildID Description ParentID
A Desc1 NULL
B Desc2 A
C Desc3 A
D Desc4 A

And I need to show this as treegrid. Before this it was working fine as I was firing 2 different queries and get Parent and Child datatable and then fire query on Child datatable.

Things were fine till that time now when I execute sp and get only 1 datatable this are not working.

Hope I have explained my self well.
Please help me how to do this...

Thanks again....

Christian Graus27-Sep-07 21:56

OK, so the issue is in your code that iterates over the table. It makes more sense to me to generate two tables and create a relationship between them. If you're spitting it out in javascrpt, the most logical thing if you have a parent child relationship, is to spit out XML.

Error messages on adding Crystal report to My project

Well, if you won't change your middle tier, then I really don't know what to suggest. What form does the data take going to the browser ? Either the data is bad, or the script code is broken.
