C# - Retrieve The Name Of The Attribute Dynamically Without Specifying The Name Of The Attribute?
Aug 13, 2010
I am developing asp.net mobile application. I am using LINQ to XML to query XML file. I am using the following query to retrieve the name & value of the query dynamically as follows
var TotalManifolds = from MF in FieldRoot.Element("FIELD-DEFINITION").Element("MANIFOLDS").Elements("MANIFOLD")
join SLT in FieldRoot.Element("FIELD-DEFINITION").Element("SLOTS").Elements("SLOT")
on (string)MF.Attribute("MID") equals (string)SLT.Attribute("PARENT")
select new
{
SlotName = (string)SLT.Attribute("NAME").Value,
SlotValue = (string)SLT.Attribute("NAME").Value
};
In the following statement of above query I want to retrive the name of the attribure dynamically without explicitly specifying the name of the attribute SlotName = (string)SLT.Attribute("NAME").Value Here I am explicitly specifying the name. I want to code which can dynamically retrieve the name of the attribute. I am new to Linq to xml. how this can be done programatically? or can you provide me the link through which I can resolve the above issue ?

I created a simple Master Page in Visual Studio 2008:
<%@
Master
Language="VB"
CodeFile="MasterPage.master.vb"
Inherits="MasterPage" %>
<!DOCTYPE
html
PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
and got green underlined 'Master' with two warning messages: 1.Validation (ASP.NET): This attribute name must be followed byan equal (=) sign and a value. If the value is in quotation marks, the quotation marks must match. 2. Validation (ASP.NET): Attribute 'Master' is not a valid attribute of element 'Control'.How I can get rid of the messages?

I installed Microsoft Visual Studio 2010 Ultimate Trial and converted existing asp.net 2.0 web application and I am getting this error: znrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. It's coming from this section in the web.config which was auto-generated by VS2010 when I converted the project:

So I was told the following would not be possible:
I have a aspx page that has a number of dropdowns. Each dropdown is set with either a class=leftcolumn or class=rightcolumn.
I need to assign an attribute:
propertyID.Attributes["nameOfAttribute"] = "false";
But instead of manually writing out each controlID and setting its attribute with the line above, I had hoped there was a way to go through and set the attribute on each control ID if it had class=leftcolumn.
This is something I know is possible to do through JQuery easily, but I need it on the code behind during load.

I am trying to achieve a SSO implimentation across my websites so i am using the machine key attribute to do so.now the trouble starts here as the website the user logs in is on the .net 1.1 framework and the website it it navigating to is .net 4.0.I have share the same machine-key across both the application . It works fine in my testing environment but as i move to the deployment server ,it just dosent work !So what i could do is read this article on MSDN :
http://msdn.microsoft.com/en-us/library/eb0zx8fc.aspx
this tells me to add a domin attribute like below
<forms loginUrl="~Login.aspx" defaultUrl="Default.aspx" protection="All" timeout="80" name=".ASPXAuth" domain="asbc.com"/>
but this thing just dosent work on the 1.1 application and throws an error Unrecognized attribute 'domain'.
Where do i get to mention the domin in my 1.1 application.?

I want to add/edit available siteMap providers in web.config file from code behind.
I am using the siteMap providers currently in the application web.config in a format given below:
<siteMap>
<providers>
<add siteMapFile="~/App_Themes/MyAppDefault/MySiteMap.sitemap"
name="MyAppDefault" type="System.Web.XmlSiteMapProvider" />
</providers>
</siteMap>
This is allowing my application user to show up a different Site Map as and when the theme is changed.
But when I tried to do the same with the following code I faced with an issue.
configuration = WebConfigurationManager.OpenWebConfiguration("~")
section = CType(configuration.GetSection("system.web/siteMap"), SiteMapSection)
Dim provider As New ProviderSettings()
If Not section Is Nothing Then
provider.Name = txtError.Text
provider.Type = "System.Web.XmlSiteMapProvider"
section.Providers.Add(provider)
configuration.Save()
End If
This code is not allowing a provider.siteMapFile property (provideer is the ProviderSettings object).
As well the maximum possible way I can add a new SiteMap provider in web.config is as follows
<siteMap>
<providers>
<add name="MyAppCustom" type="System.Web.XmlSiteMapProvider" />
</providers>
</siteMap>
If anybody can suggest a way for me to add/edit the 'siteMapFile' attribute of the provider.

I'm using webforms ASP.NET, with masterpages. I want to add a LANG attribute to the <title> tag. ASP.NET automatically generates a title tag. I've tried adding my own tag with an ID and runat="server", like this:
<title id="titleBlock" runat="server"></title>
When doing this, I can set an attribute like the following without any errors.
titleBlock.Attributes.Add("lang", "it");
However, ASP.NET wipes out my <title> tag completely and puts its own in without my LANG attribute. Is there any way to accomplish this?

<asp:TextBox ID="TextBox1" runat="server" ReadOnly="true"></asp:TextBox>
I am not able to get the changed value ( I have attached a ajax calender with this textbox)
in code behind because it is readonly
I can do this using TextBox1.Attributes.Add("readonly", "readonly"); or I can get the correct last value using Request.Form[TextBox1.UniqueID]

In ASP.NET, you can add custom HTML tag attributes to a UserControl via
myLabel.Attributes['my-custom-attribute'] = "someValue";
// or Attributes.Add()
but how can I add an attribute that doesn't have a value? For example, (and I'm not saying that this is what I need) the W3C specification only needs the checked attribute present in a checkbox to consider it checked (instead of checked='true' or something).
<span ID="ctl-blah-blah-myLabel" my-custom-attribute>some text</span>
I'm looking into using something like this to tag specific elements on my page for some client-side behavior. I know that I can do the same with classes, but (1) classes are iffy to manipulate server-side, and (2) I kind of don't want to pollute my class declarations just for tagging (that may be weird for some, I know).

This may be something simple, but I am completely new to ASP.NET. I have been reading some tutorials based on W3Schools, and I have copied one of the files and tried to play with it by changing an element with a value to storing that same value in the attribute. Here is the edited XML (my.xml):
<?xml version="1.0" encoding="ISO-8859-1"?>
<countries>
<country>
<text value="N">Norway</text>
</country>
<country>
<text value="S">Sweden</text>
</country>
</countries>
I want to extract the N and S and use them as tooltips. Here is my aspx file:
<%@ Import Namespace="System.Data" %>
<script runat="server">
sub Page_Load
if Not Page.IsPostBack then
dim mycdcatalog=New DataSet
my.ReadXml(MapPath("my.xml"))
my.DataSource=my
my.DataBind()
end if
end sub
</script>
<html>
<body>
form runat="server">
<asp:Repeater id="my" runat="server">
HeaderTemplate>
table border="1" width="100%">
<tr>
<th>Name</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td title="<%#Container.DataItem.("text").Attributes["value"]%><%#Container.DataItem("text")%> </td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</form>
</body>
</html>
What have I missed here?

Is it possible to set "for"(AssociatedControlID) attribute using jQuery? I am trying something like this to set it to the very next control that appears after label:
$('label.asssociateClass').each(function()
{
var toAssociate = $(this).next(':input');
$(this).attr("for", toAssociate.attr("id"));
});
The problem is that if I don't set it on a server through AssociatedControlID it never gets here since it's rendered as span instead of label in that case. Is there a way to overcome this or I have to do it on a server?
