Altering TreeNode Text Before/After Expand2/19/2008 10:38:49 AM

0/0

Hi all,

 I am populating a TreeView on the "OnTreeNodePopulate" event, from a Database. Sometimes there is a lot of data to populate in the TreeView (and sometimes the Database is just a bit slow). I wanted to know, how could I go about altering the TreeNode, which is expanding to change it's text before and after, it is being populated.

 Example:

Normal: [+]--MyTreeNode
Before Expand: [+]--[EXPANDING]
After Expand: [-]--MyTreeNode

Could anybody help me out here? I'm fairly new to ASP.NET, so I'm not too sure what to try.

Regards,
CD

Hi,

You can try to change the treenode's text in the TreeView's reeNodeExpanded or TreeNodeCollapsed event.

 

Hope it helps.

Please remember to mark the replies as answers if they help and unmark them if they provide no help.


Yours sincerely,
Amanda Wang
