View 1 RepliesUsers want to have the ability on a page to have a treeview with hierarchy that can be updated by dragging and dropping from a listbox. They can drag a change request from the listbox and drop it on the treeview as a parent request or a child of one of the treenodes. There also needs to be the abililty to drag and drop from within the treeview. With all the changes being done, the item from the listbox would also need to have a field changed to either Parent = 'Yes' or IsChildOf = parent id. My first question is;
1) Is all of this possible?
2) Know of any samples or examples of how this would be accomplished?
3) Is there a better way of doing the hierarchy with parent and children then mentioned above (I hope there is)?
4) What have others done for something like this?
I am open to other thoughts of doing this a better way and I'm sure the users can be persuaded. Prepping for a Access conversion project beginning of year. And if this conversion from A2007 to ASP.NET goes well, there is another major conversion waiting in the wings.

View 2 RepliesHow can i create a Treeview with Drag drop functionality.
I want to show the values in my tree from DB.
I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?
how can add , edit, delete nodes and sub nodes in treeview in vb.net 2005 and sql server2005
View 1 RepliesShould be easy but I cannot find a property which allows me to right align the nodes in a treeview.
I've tried adding text-align: right in a CSS declaration linked from NodeStyle > CssClass. Nothing.
Second: Is there a way to select more than one node in tree view (like we do in Windows Explorer, by pressing SHIFT or CTRL) ?

View 1 RepliesI'm coding an Webpage in VS.NET 2010[C#] that scans the Serial Number of Product into a Treeview in a Work Order > Box > Product hierarchy.
What I wanted to do was to use the following to Remove the ChildNodes:
//Use the GetEnumerator method to create an enumerator that contains the root node data.
IEnumerator nodeEnumerator = myTreeView.CheckedNodes.GetEnumerator();
// Iterate through the enumerator to display the root nodes.
while (nodeEnumerator.MoveNext())
{
/In here I would like to Remove the TreeNode
//MessageBox(((TreeNode)(nodeEnumerator.Current)).Text);
}
}
else
{
MessageBox("The TreeView control does not have any nodes.");
}
In my Treeview i have for all nodes checkboxes.
parent
child
leaf
leaf
leaf
parent
child
leaf
child
leaf
1. when i check leaf - i want to have checked child and parent too
2. when i check parent - i want to have checked child and leaf

3. on a save button i only want to save checked leaf to DB - if they are not checked delete from DB
This is so frustrating...that such a simple feature should not be included in the design of this control. I am using the cssfriendly adapters and the rendered code is shown below.
I thought I might be able to use the adapter's treeview JS function ExpandCollapse__AspNetTreeView(this) since this is what is called when I click on the node that causes it to expand/contract. But that did not work.
I have seen other code posted but it seemed to imply the treeview was a table not a ul.
Does anyone know how to simply expand or collapse all nodes from a link button without doing the postback. Of course the postback works but what a waste to have to postback to do such a simple action.
Why doesn' t MS consider the users and developers when creating these controls and tools? Stupid!

I've created a custom implementation of SiteMapNode. I've attached it to Menu and it works ok. I've attached it to TreeView and it shows only nodes of one level. If I specify at SiteMapDataSource's ShowStartingNode==true, then I will see only root node and no expand buttons, if I specify ShowStartingNode==false, then I will see root's child nodes and no expand buttons also. What's wrong?

I am trying to maintain the state of a TreeView on postback. I have a simple method to save the state of the tree on postback but it does not seem to capture the Expanded and the Selected state. Also, i have another method to restore the tree state after a postback. When a user selects an item in the TreeView i would like to have this item highlighted/selected. Along those lines i would also like to have all expanded or collapsed mainated after a postback.
