• ASP.Net 2.0 - Treeview PopulateOnDemand doesn't work after postback

  Hello All... I'm using a Treeview (ASP 2.0, VS 2005) that has the following properties set: EnableClientScript = "true" PopulateNodesFromClient = "true" PopulateOnDemand = "true" While loading nodes I set, programatically, leaf node's SelectAction to TreeNodeSelectAction.Select (I need do this to let the user select a bunch of nodes and add them to a table on the same page). I can populate the nodes (by expanding) as long as I do NOT select a leaf node. Once I select a leaf node I can no longer exapnd

• Re: TreeView select node behavior

  Kiks: Hello... I'm using the treeview control in VS 2005, .Net 2.0. The treeview has several levels of nodes, which I'm loading on demand. My leaf nodes SelectAction is set to TreeNodeSelectAction.Select . The selection works fine (which of course does a post back) but then if I try to expand (i.e. load on demand thru client-side callback) the other nodes, that have leaves, will not expand....what's going on there? P.S. Everything works fine in Debug mode though, after publishing the website only

• Re: ASP.NET 2.0 Treeview Checkboxes - Check All - Javascript

  Hockey_Scott, thanks for sharing that. I think, I already posted the full version of very lengthy solution (may be similar to your solution or not) in my ealrlier posts. But, see Davidovitz 's post of shorter and cleaner version of the function which misses the same little functionality that you are talking about. If anybody has a TOTAL solution to Davidovitz's, please post it. Thanks!

  This routine should work fine on IE and I haven't tested on any other browsers. Try using the tips that others had posted, for multi browser compatibility. In you case it looks like getElementsByTagName is returning nothing ...

• Re: ASP.Net 2.0, Treeview Control PopulateOnDemand with Checkboxes, scanning thru treeview for checked nodes

  Danny...you are right the issue was elsewhere... It was in my sql statement, I was losing some of the parameters (when I postback) that are required in my where condition... As you mentioned in your earlier replies when it tries to create the nodes permanently, the second time, my Dataset was empty so no nodes at all.... I'm sorry for not noticing that earlier, but I'm glad, I at least caught it now... Danny, I really appreciate your time and help. Thanks much. For those who is following this thread

  Thanks again. That didn't do it either...I've tried calling my Filter() routine (that I've posted above) in the events you mentioned and also several other events...it doesn't still know the presence of the new child nodes. -- Anybody out there had this problem before, pls pls pls...reply...Thanks

• Re: ASP.Net 2.0, Treeview Control PopulateOnDemand with Checkboxes, scanning thru treeview for checked nodes

  I've an ImageButton, server side control and I'm trying to read thru after I click this image, i.e after the page is postback'd...even then no luck...I still have the same problem.... I've If Page.IsPostBack Then MsgBox( "Posted" ) in Page_Load event to make sure the page is being posted and the message is displayed before the execution gets to my subroutines that scan thru the nodes... I don't have any client side scripting when I click the image, though... Am I missing something? Please help. Thanks
