VS 2008 - Deleting Nodes From Tree View Generated From Database
Jan 25, 2012
I have been trying to delete nodes from a tree view that is being generated from a database. I have the code written and it works, but only on the root Nodes. It will not delete Parents/Childs/Leaf, it will if I delete the root, but I also want to be able to delete parent nodes and such.
Right now i have this code so far
Dim tn As TreeNode = treeView.SelectedNode
treeView.Nodes.Remove(tn)
I know that I can just use treeView.Nodes.Remove(treeView.SelectedNode) but was doing some error checking to see if I could firgue out what was going on. I am using VB6, I am not so worried about the database deleting at the moment. I would prefer not to use the Clear() method as this will remove all the nodes I only want to remove certain ones and keep the rest.

In my website, I have a TreeView that has this structure:
Root
|-Leaf
|-Parent
|--Leaf
|--Leaf
|--Child
|---Leaf
|---Leaf
|--Child
|---Leaf
|---Leaf
Is it possible to make the tree in a "collapsed" state where all the Leaf nodes and ONLY leaf nodes are hidden from view until its parent node is expanded? The ideal solution would be to do this without a postback, but any solution at this time would be helpful. The "collapsed" view would look like this:
Root
|-Parent
|--Child
|--Child
Expanding the Root, Parent or Child nodes should show their Leaf nodes. Collapsing the node should re-hide its leaf nodes, but leave the child nodes visible.

I want to create a Tree View using XML that is fetched from SQL Server. How I can directly assigned to tree view, the below code I tried, but throwing error 'dsXML' is not an IHierarchicalDataSource. The XML heirarchy is proper. When I use XmlDataSource with the xml file, tree view is shown.
<asp:SqlDataSource runat="server" ID="dsXML" ProviderName="System.Data.SqlClient"
ConnectionString="Data Source=Server;Initial Catalog=database1;Persist Security Info=True;User ID=userid;Password=password"
SelectCommandType="StoredProcedure" SelectCommand="spGetXML">

When installing an Umbraco site, I changed my umbraco admin url from '/umbraco/' to '/myadminurl/', even before I went through the install process.
Just like it's documented, I changed in the web.config the keys 'umbracoReservedPaths' and 'umbracoPath' to match my new admin url.
Installed and everything is working fine, except for one thing: All the nodes in the trees in all sections aren't showing any thumbnails. There used to be a win folder thumb before each tree node, but now it's just empty, except for the 'packages' node in the developer section, and for the recycle bin thumb.

Using the Web Platform installer, in installed both the Visual Web Developer Express 2008 and SQL Server Management Studio Express 2008. Next, I connected to my local SQL Server Express 2008 and created a simple database and table using Visual Web Developer Express 2008 where the database file resided in the app data folder of my website. I can connect and explore the table from both Visual
Web Developer 2008 as well as the full blown version of Visual Studio 2008.

I have been having an issue when expanding a treeview, it looks fine when I load it, but when I click on a parent node it does expand, but also puts like 2 other parent nodes undernearth it. I am thinking it's because the treeview is saying that the parent nodes that have children have an index of 0, while everything else as there own index.

I have a web application where I am using asp.net tree view control to show data. No I want that this tree view structure has to exported to excel. Following is the code which do this for me.
private void ExportSiteStructure()
{
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
TreeVWSite.RenderControl(oHtmlTextWriter);
if (TreeVWGroups.Nodes.Count > 0)
{
TreeVWGroups.RenderControl(oHtmlTextWriter);
}
Response.Write(oStringWriter.ToString());
Response.End();
}
It works perfect but the report what it gives me contains all parent and child node of tree view get palced in excell cell as well as icons and checkboxes which I have use. What I want is to have only Text in excel cell that represent node of tree view and not those icons and checkboxes associated with them.
