UltraTree - Expand and Collapse

Swe2 posted over 16 years ago

Hi -

I have an UltraWinTree.UltraTree which has three level nodes. On Initializing, I have to show the tree in such a way that Nodes at level 1 and 2 are expanded and the nodes at level 3 so that the tree doen't look cluttered. All I saw is expandall and collapseall methods which applies to all nodes in the tree. Is there property to accomplish this one?

Thank you in advance.

An Override object is exposed by the control itself, so set UltraTree.Override.NodeDoubleClickAction.

Hi,
I have a situation which is a little more deep. i have an ultratree with infinite level of nodes, as in i should allow the user to generate as many nodes as the user wants. And on double clicking each and every container node, it should expand/collapse automatically.
//To expand and collapse treenode on double click

treeNode.Override.NodeDoubleClickAction = NodeDoubleClickAction.ToggleExpansionWhenExpansionIndicatorVisible;

i have set this property while loading the nodes but it works only for parent level nodes.

When or where can i set this property so that it is applicable to all the nodes??

Please reply ASAP.

Regards,

Y_MB

There's an Expanded property on the node, itself. So you could expand the node at the time you add it to the tree if it's on level 1 or 2.
