Closing Treeview nodes automatically

Hello,

I have a TreeView control with "top-level" nodes and "second-level" nodes
(probably not the correct terms) as follows:

objNode = new TreeNode();
objNode.Text = "2006";
objNode.SelectAction = TreeNodeSelectAction.Expand;
tvSide.Nodes.Add(objNode);

objChildNode = new TreeNode();
objChildNode.Text = " ·January";
objChildNode.NavigateUrl = "../2006/jan.aspx";
objNode.ChildNodes.Add(objChildNode);

objChildNode = new TreeNode();
objChildNode.Text = " ·February";
objChildNode.NavigateUrl = "../2006/feb.aspx";
objNode.ChildNodes.Add(objChildNode);

// other child nodes for 2006

objNode = new TreeNode();
objNode.Text = "2007";
objNode.SelectAction = TreeNodeSelectAction.Expand;
tvSide.Nodes.Add(objNode);

objChildNode = new TreeNode();
objChildNode.Text = " ·January";
objChildNode.NavigateUrl = "../2007/jan.aspx";
objNode.ChildNodes.Add(objChildNode);

objChildNode = new TreeNode();
objChildNode.Text = " ·February";
objChildNode.NavigateUrl = "../2007/feb.aspx";
objNode.ChildNodes.Add(objChildNode);

When I click on the 2006 node, it correctly expands to reveal the nodes
underneath it.

But, if I then click on the 2007 node, I would like it to "close up" the
2006 node as well as expanding the 2007 node. Is there a way to do this?

Thank you.

DJ

Hi, I have done this in Javascript. You can actually view source of the page
and write a generic code to handle it.

Excellent suggestion! The following code will do this, if anyone else is
interested:



N.B. this could probably be made more robust by checking that the id of the
children element ends with 'Nodes' rather than just contains 'Nodes', and
the TreeView_ToggleNode function does a fair bit more than just setting the
display style, but the above works for me and is all I need at the moment.

Closing Nodes upon Selection of anotherone

Hi guys. I have a treeview that should close is nodes when one of them is expanded just as this example. But there is a "catch"-

My treeview structure is as follows

RootNode
--------Child1
----------Sub1Child1
----------Sub1Child2
--------Child2
----------Sub2Child1
----------Sub2Child2

If I expand Sub1Child1 then Sub1Child2 and Child2 should be Collapsed.

Can you give me a hand here? I've been trying to do this for some time now and got no results :S

Thanks

Hi, Just wondering whether you got to do this. If not let me know and I can
help you. I did the same in one of my projects.

Thanks
