Like first clear childnodes before you add them,and you will not get duplicate childnodes.

No, thats not it.

TreeView obTreeView = (TreeView)Session["m_obTreeView"];
//1//obTreeView.SelectedNode.ChildNodes.Clear();
//2//obTreeView.Nodes.Clear();
string strDateTimeStamp = DateTime.Now.ToString("hhmmss");

line //1// makes no difference
line //2// casts nullreferenceexception

Before firing SelectedNodeChanged event call loop down below.

<br />
if (obTreeView.Nodes.Count > 0)<br />
    {<br />
        for (int i = 0; i <= obTreeView.Nodes.Count - 1; i++)<br />
        {<br />
            obTreeView.Nodes[i].ChildNodes.Clear();<br />
        }<br />
       <br />
    }<br />
obTreeView.SelectedNodeChanged += new EventHandler(this.Node_Change);<br />
<br />

thanks for the help Blue Boy, it worked.
If I had better understanding of the asp.net dynamics Id probably know why it worked Hmmm | :|

why clear the treeview, and load it again, instead of just keeping the already populated tree?
wouldnt it save time?
and why clear the treeview in page_load and not the node_change function?
thanks again, regards, Siggi

Your TreeView populated on each time when page is loaded so because of it you have to clear childitems before add them.

dynamic chart controls

hi all,

I am currently using asp.net 2.0 with vb.net and want to use dynamic chart controls in my application.The sample chart controls should be similar to the controls in this link (http://www.macroaxis.com).
Please give me some ideas how can I start to make a sample application with the chart dynamic controls present in that site.

I think flash has used in the site but how can i do the same with asp.net 2.0.

Thanks and regards

You might consider purchasing a professional chart control package.

One to consider would be Dundas Chart[^].

Hi Bikash,
There are many chart control are available for .net. If you are using .NET 3.5 SP1 , Microsoft having their own Chart Control.
If you are looking for 3rd Party, you can go with Dundas and Fusion Chart Big Grin | :-D

Scroll and highlight the html table's row ?

27-Jul-09 1:36

In Page_Load check if user is logged in,in case is not then redirect to login page.
Search on google and you will find more usefull manners how to manage user's login.

Use a Session object in your login page and use an if statement in your redirected page Page-load method to check the session object.

I understand that. I just want to know how you are relating this with Scrolling ? You are talking about selection of Rows?
