1 / 0
2 /1/ 1
3 /2/ 1
4 /1/1/ 2

C#- bind treeview runtime using dataset and data table
simple example
I have searched a while for a good solution for this, but i have only found solutions with XML files and mssql.
I have 2 tables. Table parent holds the parent nodes and table child holds the childnodes related to the parentnodes.
Table parent looks like this: pID as integer (pk), parentName as varchar
Table child looks like this: cID as integer (pk), parentID as integer, childName as varchar
I want to populate the treeview with data from these tables! How can i do that?

I am very new to .NET platform (from a PHP background) and I am developing a simple multi-step online form. The user can come back and edit the form after they have initially completed it.User clicks edit form. The information saved in the database is retrieved and populated in the form elements like textbox, dropdown box, image files. And this is all inside a wizard control.
I can do this in a gridview using datasource and databind but the datasource doesn't seem to work with wizard.
can populate a treeview from an ftp folder
View 3 RepliesI'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).

I have a table in SQL fro "Categories" and I need populate a TreeView in my Asp.net page.
My question are:
1 - How can i populate the TreeView?
2 - How can i use the TreeView to modify the hierarchy of my Categories?
NOTE: I use "hierarchyid" SQL Columns!
CREATE TABLE dbo.CmsCategories
(
CategoryId int NOT NULL IDENTITY (0,1) -- Seed = 0 and Increment= 1
CONSTRAINT PK_CmsCategories_CategoryId PRIMARY KEY,
Title nvarchar(40) NOT NULL,
MetaDescription nvarchar(160) NOT NULL,
MetaKeyword nvarchar(128) NOT NULL,
Summary nvarchar(256) NOT NULL,
IsPublished bit NOT NULL
CONSTRAINT DF_CmsCategories_IsPublished DEFAULT 1,
CategoryNode hierarchyid NOT NULL,
CategoryNodeLevel AS CategoryNode.GetLevel()
);
I have a list of Categories which I need to bind to a TreeView control in WPF and I can't find a working tutorial or get it working.My Category class consist of (ID, Title, ParentID). If the Category is a top level category the parentID is null.Can anyone sow me how to bind this to a treeview?
View 3 RepliesI have a large XML file (3000+ nodes) that I want to represent in a TreeView on ASP.NET. I cannot databind it to a XMLDataSource because loading the TreeView will then be way too slow (I never even waited long enough to see it finish...)
So the solution for this would be to use the PopulateOnDemand property of the TreeNodes to load data only when needed. Problem is, I can't think of a way to acheive this...
How can-I, based on the ID of a node, search a XMLDocument to get all the childnodes of the node having this ID?
XML would look like that:
<document ID=1>
<document ID=2>
<document ID=3>
</document>
</document>
<document ID=4>
</document>
</document>
There are nor rules on how much levels it can go down or anything...
I'm currently working on a Web Site application project that requires a treeview to be heirarchically structured based on the attribute ids of each node rather than the format of the XML.
[Code]....
At present the above is lining up all names under each other, I would like the hierarchy to be based on the attribute parentid and Id. For example: Jane Smith should be a child of Joe smith and Bob Turner is a Child of Jane Smith.

I am binding the XML Data to treeview using XMLDataSource. Its working fime, but when the Number of nodes and childnodes increases, the treenode expand and to display the content in iframe takes moer time.
<asp:TreeView ID="TreeView1" OnSelectedNodeChanged = "OnClick" runat="server"
ExpandDepth="0" ShowExpandCollapse="true" ForeColor="Red" Font-Underline = "false"
ondatabinding="TreeView1_DataBinding" CollapseImageUrl = "Resources/TocColapse.bmp" ExpandImageUrl = "Resources/TocParent.bmp" Font-Names="Arial" >
<SelectedNodeStyle Font-Underline="false" BackColor="White" ForeColor="#0483e0" />
<NodeStyle Font-Size="11pt" ForeColor="white" HorizontalPadding="5px"
NodeSpacing="0px" VerticalPadding="0px" Font-Underline = "false" />
<ParentNodeStyle ForeColor="#0483e0" Font-Underline = "false" />
<LeafNodeStyle ForeColor="#0483e0" Font-Underline = "false" ImageUrl = "Resources/TocChild.bmp" />
</asp:TreeView>
<asp:XmlDataSource ID="XmlDataSource1" runat="server" XPath="/*/*" EnableCaching = "false" ></asp:XmlDataSource>
In OnDataBinding event of treeview I implemented the following code:
TreeNodeBinding[] TreeNode = new TreeNodeBinding[Count];
for (int i = 0; i < Count; i++)
{
TreeNode[i] = new TreeNodeBinding();
TreeNode[i].DataMember = TableOfContents[i].GetElementName();
TreeNode[i].TextField = TableOfContents[i].GetFirstAttributeName();
TreeNode[i].ValueField = TableOfContents[i].GetSecondAttributeName();
// TreeNode[i].Target = "contentFrame";
TreeView1.DataBindings.Add(TreeNode[i]);
}
I have a treeview associated with an XML Datasource but the treeview loads only the xml node names whereas i want to assign the values in the xml nodes to the treeview instead of typing <databinding> for each node in the source file. I want to write code which dynamically read the xml nodes and populatethe treeview or is there any property which will read the values also ?
