I need to display a self referencing table ( < 500 records) in a treeview but not sure what is the best way to do it.
Currently i'm thinking of building a nested XML using dataset relationships, then assign it to the Treeview control. Thing is I'm quite new to ASP so still trying to find my feet.
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 5 RepliesI've created a custom implementation of SiteMapNode. I've attached it to Menu and it works ok. I've attached it to TreeView and it shows only nodes of one level. If I specify at SiteMapDataSource's ShowStartingNode==true, then I will see only root node and no expand buttons, if I specify ShowStartingNode==false, then I will see root's child nodes and no expand buttons also. What's wrong?
View 2 RepliesI need populate a TreeView control to display Hierarchy Data from a DataBase.
The Hierarchy Order has been dictated by a Column, in my DB called "CategoryNodeString" and "CategoryNodeLevel".
/ = Root
Example:

1 / 0
2 /1/ 1
3 /2/ 1
4 /1/1/ 2
5 /1/2/ 2
6 /1/1/1 3

Periodically 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.

View 1 RepliesI have a page that has a treeview and an Iframe. When I click a treeview entry, I display a gridview in the Iframe. The gridview has a link in the commands column that should display another page.The problem is, when I click the link, the page does not display. I have tried the following (partial code):

I can break in the LineItemDocs code behind, so it is getting to the page, but the LineItemDocs page does not render!The effect that I am going for is to click a treenode, display a page that has some functionality and contains a link. Click the link to display another page that contains additional functionality. Then be able to back-out to where I started. The treenode displays different gridviews (14 of them), depending on the node clicked.

I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.
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 ?
