I am new to Dot net.
I have Treeview with 4 child nodes.I have 4 XML Files.
When i click on each child node,i have to display XML File
in GiridView...ie First child node ----- CLICk-----> First XML File
Second child node ----- CLICk-----> Second XML File
I have a class Person with three properties, ID, Name, Registered. I have the following array of this class
Person1 (ID=A00 ,Name=Andy )
Person2 (ID=A01 ,Name=John )
Person3 (ID=A02 ,Name=Lina )
Person4 (ID=B00 ,Name=Rachel )
Person5 (ID=B01 ,Name=Peter )
Person6 (ID=C00 ,Name=Hans )
Person6 (ID=C01 ,Name=Emily )
I need to show this array in a treeview in this way: When the person has ID finished in 00, it is showed how the father node, and the other persons starting with the same letter are the child nodes.
In this case Andy would be the father indented 0, and john and lina would be his childs indented 1.
I need to show this structure in a checkbox treeview and when I select the father checkbox, the child checkbox must be selected too.
I have a treeview like this
root1
----p1
---p2
---p3
root2
-----p1
----p2
----p3
like that
when i click on p3 of root2 display data.
but how to know which parent of child is selected?
My TreeView controls is rendering CheckBoxes on Leaf nodes. I want to bind to those nodes the ID of the underlying data item. I am not sure I can do this declaratively or if I need to hook up to the TreeNodeDataBound event. If the latter, how would I go about achieving this?
View 3 RepliesI see that the data is there when I autogenerate. I can't seem to understand how to get the values from the nodes? Any reference anywhere on the ways to set the properties of databandings/TreeNodeBinding?
Like I need the name inside here
<TaxonomyName>Resource Enhancement</TaxonomyName>
Using
<asp:TreeView ID="tvSubmissionCategories" runat="server" DataSourceID="xdsSubmissionCategories"
AutoGenerateDataBindings="False">
<DataBindings>
<asp:TreeNodeBinding DataMember="Taxonomy" Text="TextThing" />
</DataBindings>
</asp:TreeView>

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 ?
View 1 RepliesPeriodically a rash of occurrences of the following error happen. I believe they're the result of hack attempts. Whether that's the case or not, my question is how can I handle the error? I want to avoid unhandled exceptions. The TreeView control is just
a standard .Net TreeView control, not a custom one. If you suggest a code solution, please code it in VB.Net as that's what I'm using.

I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

View 1 RepliesWhat's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
May I know what is the diffrence between static binding and dynamic binding and which binding is used in
1)Virtual Functions
2)Abstract Class
3)Function Overloading
4)Operator Overloading
5)Fuction Overriding
6)Delegates
I have a treeview that i fill from a database, when i add a new row to a database, the treeview is not updating.Even the reload of an internet explorer doesn't help, It does updates only after i press stop debugging button and turn it on again.Here is the code:

I am using treeview to display records from 4-5 SQL Tables. Currently I am using 4-5 different stored procedures to retrieve data based on a dropdownlist value.The tree is loaded everytime the value in the dropdownlist is changed by the user.
Is there a faster way to load treeview as everytime a new selection is made, the treeview is binded again. Or is there any way I can optimize the actions I am performing now to bind the treeview?
i would like to add images for a tree view like for root node one image and for child node other like that i would like to add different images for nodes..
View 1 RepliesI am using Tree view to display Categories & SubCategories under it. It's working fine. to create a Tree View I had used,
http://aspalliance.com/732.
Problem is that I want my TreeView to be expanded. How can one do that? Moreover, From another page when I click a Product, I want that in treeView that Category(under which Product falls), should be expanded & node(ie selected Product) should be highlighted.
I am using treeview for all of the links that I have created in my Web.sitemap folder. However, I was wondering if there was a way that I could automatically logout after pressing the logout link in the treeview.
I've tried inserting the following code in the logout link within the code behind file :
protected void Page_Load(object sender, EventArgs e)
I have a small problem encountered on using Treeview. I have Two pages on the sample. On the first page you can see a button that says "Add Category" and a grid that displays all the previously added categories (coming from a sql db). Upon clicking the "Add Category" button here comes the second page. On that page, we can see a two radio button,a textbox and a submit button. The first radio button says "Add new category", then the second radio says "Add a sub category on the existing category" which shows up the treeview upon clicking. Upon entering the new category and clicking submit, it will return on the First Page and you can see the on the grid the newly added category. Upon adding again and clicking the "add a sub category" the newly added category before was not added even though it was added on the database. Both Grid and the Treeview shares the same SQL statements on retrieving data.
I've tried adding an update panel and even manually updating the Treeview and still the newly item added was not shown. Possible solution I ever found was refreshing the page and I don't want to do that since its kinda ugly. Take note that upon adding a new category and submit it, it will return to the 1st page and upon adding a new category and choosing the sub category radio button showing up the treeview, the newly added category was not shown.
I have read many posts in the past about TreeView in Custom CompositeControls and using RenderControl but have yet to see a solution. I declare a new Tree in the CreateChildControls method and in the render I try to call the RenderControls method and it gave me an object reference not set to instance of an object error. I have set the SkipLinkText to Nothing, String.Empty and "". Once I do that I get the second stack trace. The control worked when it was a control on the aspx page.

View 2 Repliesi am using treeview in my web application, when i collapse all the node root node becomes disconnect. i mean the root node line is broken. can any one tell me how to fix this issue.
this is my code
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TreeTest.aspx.cs" Inherits="TreeTest" %>
What I am acheiving is a simple treeview which will have a tree structure
dir1
-- xx
dir2
Simple stuff !. Here is the code
TreeNode tree1 = new TreeNode("dir1", "", "", "dir1", "");
tree.Nodes.Add(tree1);
TreeNode node = new TreeNode("xx", "xx");
tree1.ChildNodes.Add(node);
TreeNode tree2 = new TreeNode("dir2", "", "", "dir2", "");
tree.Nodes.Add(tree2);
Now I want to do is collapse all the tree and find a particular node e.g dir1xx
I have put the code
tree.CollapseAll();
tree.FindNode("dir1").Select(); <-- falls over
tree.FindNode("dir1").Expand();
tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();
but it falls over on the 2nd line with object not set
