ADO.NET :: Linq To Xml - Get The Element "question" From The XML

Dec 15, 2010

I have an XML file of the following kind:

<Root>
<question QuestionIndex="0">
<QuestionTitle>What is the meaning of life?</QuestionTitle>
<UserChoice>1</UserChoice>
<question QuestionIndex="1">
<QuestionTitle>How much is 1+1?</QuestionTitle>
<UserChoice>3</UserChoice>
</Root>

I want to get the element "question" from the XML, if given the "QuestionIndex" attribute. I tried the following code:

XElement q = (XElement)from question in doc.Descendants("Root")
where (int)question.Attribute("QuestionIndex") == index
select question;

but it throws InvalidCastException.

Get The Value Of An XML Element Using Linq Even When Empty?

May 13, 2010

I am using ASP.NET in VB.

I have an XML document which contains all the details of staff in my company...

<staff>
<staffName>Test Staff</staffName>
<staffTitle>Slave</staffTitle>
<staffDepartmentName>Finance</staffDepartmentName>
<staffOffice>London</staffOffice>
<staffEmail>t.staff@company.co.uk</staffEmail>
<staffPhone>0207 123 456</staffPhone>
<staffNotes>Working hours Mon to Thurs 9.15 - 5.15</staffNotes>
<staffBio></staffBio>
</staff>

As you can see, some nodes do not always contain data for ever member of staff; only Directors have biographies.

I access the values like this...

For Each staff In ( _
From matches In myXMLFile.Descendants("staff").Descendants("staffName") _
Where matches.Nodes(0).ToString.ToLower.Contains(LCase(search)) _
Order By matches.Value _
Select matches)......

Once it gets to staffBio I get an error saying "Object reference not set to an instance of an object." obviously because that node does not exist.

My question is how can I assign the value to a variable even when it is empty without having to do a conditional check before each assignment?

What Is Difference Between Web.config Assemblies Element And Project File Reference Element

Sep 29, 2010

I'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.

I was wondering, what is the difference between assemblies/references added in either location?

AJAX :: Element 'ToolkitScriptManager' Is Not A Known Element - For Network Drive Websites

Feb 2, 2011

I have noticed that when I create a website in a network drive and use the Ajax toolkit I get :

Element 'ToolkitScriptManager' is not a known element

I also noticed that after adding the ToolkitScriptManager it doesn't add the ID in the source code, it looks like this:

<asp:ToolkitScriptManager runat="server"></asp:ToolkisScriptManager>

Is missing the ID="ToolkitScriptManager1" part.

This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.

You're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap

Element 'Chart' Is Not A Known Element - DotnetCHARTING?

May 9, 2010

I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll.

web.config:

<add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/>

The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts.

Each page has a reference to the assembly:

Element 'X' Is Not A Known Element - Web Application?

Aug 23, 2010

I converted a forms website into an application and everything has been working just fine until now. I keep getting the green squiggly lines and the error that Element 'X' is not a known element. This is on almost every element, Gridview, Label, Update Panel, Hyperlink Field, Bound Field, etc...

my web.config contains

<pages theme="basic">
<controls>
<add tagPrefix="ajax" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit"/>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</controls>
</pages>

so ajax and asp are viable prefixes. The very odd thing is that it is only happening on a few user controls, all other user controls are fine and the errors never show up. I have tried rebooting and everything and nothing seems to fix it. All masterpages, web paages, and about 90% of the user controls are fine, its only on a few user controls and super annoying!
