View 2 RepliesThis is the xml I got as an output from the WriteXmlString() of Infragistics ultrawebtree. I am using this to create another Infragistics ultrawebtree with the same structure. But here I don't want the <Url>something.aspx..</Url>. I want that to be like this <Url><Url>. So how I can able to remove. This I get as a String. So I used Regex.Replace(). But it will work for certain conditions,but for some case it will destruct the xml by deleting some xml tags and xml became not valid due to missing of tags.

I was writing a generic class to read RSS feed from various source and to consolidate in one collection of object in VB.net.
Basically the function - using LINQ to XML - is working properly, but I have a problem when the RSS feed I am trying to read does not contain one of the node (as you know, many of them are optional). I would the returned value to be an empty string or nothing, but instead I get a runtime error back. I searched the web for the same problem and I found this post [URL] that apparently explain a workaround, but it does not work with my code.
I am also surprised by the little resources I am finding about this issue, so I am now wondering if I am even putting the question in the right terms...

How do I work out what the namespace declaration is for the Extension node?I want to return all of the child nodes under: GPO->User->ExtensionData->Extension..[code]I get the following error: Sequence contains no elements..Also, the XML sample I have provided is only a small snippet, the ExtensionData->Extension nodes can be nested in different areas, so I was hoping to find the way of specifying the full path.
View 2 RepliesAfter being quite sick of the my.settings-file behavior, I started to create an XML-file (with unique values). Now this works great!!! All my settings, connectionstrings, etc are loaded from an external file and won't be overwritten by the app. itself. But I was wondering how do I save a value/setting? Simple example:

I have a listview which I am trying to remove the initial root node's indent. My problem seems to be that I can't even set the indent value of the treeview in it's properties lower than 19, and if I try something like:
TreeView2.Indent = 16
16 seems to be the lowest value that makes any visual change.

I have built a database structure that represents a category tree to help classify some of the data we have stored. The implementation is that each record in the Category table has a nullable foreign key back into the Category table to represent the parent Category of this category (one-to-many), essentially allowing for subcategories within a broader parent level. There is a CategoryMembership table that links a record in the Item table to its respective Category (many-to-many). I have created the DBML for this database, and it has a member access structure that includes the following:

I have a multi-client DB (multitennant) with several tables.Two of these tables are tblEmployees and tblTitles.Now I have a relationship from tblEmployees.empTitle to tblTitles.ttlID.That far everything is working.But now I have to make the application for multiple clients/tennants.So I added the fields tblEmployees.empClient and tblTitles.ttlClient and included them into the association.This works fine for reading and for setting the persons title as well.But if I try to remove the title (set it to NULL), SQL to Linq tries to modify both tblEmployees.empTitle and tblEmploy ees. empClient with is not allowed because tblEmployees.empClient is part of the primary key.And so I get the following error:[code]How can I tell SQL to Linq only to modify field tblEmployees.empTitle???

I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:

How to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?
I know its probably really simple, but i tried lots of stuff, i just cant get it working.
Basically, it refuses to find the node when the root node contains an attribute.
[code]...
When I do xml.SelectNodes("DataSet") with the xmlns in the root tag, it finds no nodes. If I remove the xmlns attribute, it works fine.How can I make it work while leaving the attribute?
