I got a couple of question

how can we control the child node creation ASPxTreeList
For example:

Node A
     1
        Node 1
             11
            12
            13

            Node 11
                Node11 1
                Node11 2
                Node11 3
                Node11 4
                Node11 5
                Node11 6
                Node11 7
                Node11 8
                Node11 9
                Node11 10
            
    2
    3
    4
    5
    
        For Root Node Child Nodes are 5 (1 2 3 4 5 )
        For Root Node 1 Child Nodes are 3 (11 12 13 )
        For Root Node 11 Child Nodes are 10 (11 1.....11 10)

How to force user to create child only as mentioned above.
Is there any way we can do this.
Thanks

 Hi,

You can handle the InitNewNode event.

Example:

protected void ASPxTreeList1_InitNewNode(object sender, DevExpress.Web.Data.ASPxDataInitNewRowEventArgs e) {

    int newNodeLevel = ASPxTreeList1.FindNodeByKeyValue(ASPxTreeList1.NewNodeParentKey).Level + 1;

    if (newNodeLevel > 2) ASPxTreeList1.CancelEdit();

}

I am successfully able to work with the code you showed.Thank you much, now i need to show and hide the command buttons in some nodes.(Hide) only if they are not you cannot not add or edit else show.

For example:
Node A *Do not Show (Edit New Delete) Command Buttons
     1 *Show (Edit New Delete) Buttons
        Node 1 *Do not Show (Edit New Delete) Command Buttons
             11*Show (Edit New Delete) Command Buttons
             12 *Do not Show (Edit New Delete) Command Buttons
             13*Do not Show (Edit New Delete) Command Buttons

            Node 11
                Node11 1 *Do not Show (Edit New Delete) Command Buttons
                Node11 2*Do not Show (Edit New Delete) Command Buttons
                Node11 3 *Do not Show (Edit New Delete) Command Buttons
                Node11 4*Do not Show (Edit New Delete) Command Buttons
                Node11 5*Do not Show (Edit New Delete) Command Buttons
                Node11 6*Do not Show (Edit New Delete) Command Buttons
                Node11 7*Do not Show (Edit New Delete) Command Buttons
                Node11 8*Do not Show (Edit New Delete) Command Buttons
                Node11 9*Do not Show (Edit New Delete) Command Buttons
                Node11 10*Do not Show (Edit New Delete) Command Buttons
               
In addtion
I would like to allow user's only upto 10 Nodes to be added in Node 11 if he tries to add new add paging show page 1
at the end and show edit textboxes in page 2

 Node 11
                Node11 11 *Do not Show (Edit New Delete) Command Buttons
                .
                .
                .
                .
                .
                .
                .
                .
                Node11 20*Do not Show (Edit New Delete) Command Buttons
            [1]2

Where Page 1 will hold Node 11- 1.....11-10

Page 2 will holds 11-11 - 11- 20

..

To Page N

Thanks
