Is It Possible To Iterate Through An Unordered List
Jun 21, 2010
Is it possible to iterate through an unordered list like the following in codebehind?
[Code]....
I was hoping to iterate through all the li elements of the ul checking whether NavigateUrl is equal to the current url. If it is, I was going to add a CssClass to give it a different appearance.
I think I know how to compare it to the page's url and to how to add the css class. I'm just not quite sure how you iterate through li items using a HTML Generic control.

I have a master page which has an unordered list in this way:
[code]....
These links are directed to my content pages. I am able to highligt the selected list item on hover and on active.
But I do not understand how I can highlight the selected list item as long as the user is on that specific page/link (current list item). I know that we can specify a seperate body tag and id for each of the content pages and then use CSS to highlight the current list item, but all this code rests already inside a body tag in the master page.

I am trying to implement an html definition list in which each <dt> is the <header> in the accordion, and <content> is the <dd>. No matter how I write this out I can't get it to be valid markup because of the position of the <div>s inside the definition list where divs aren't allowed.
I also tried using a unordered list but had the same validation issues. I would really like to use the accordian, but not if I have to sacrifice valid semantic markup on my page.

i am working on a dynamic tree menu with nested <ul><li>-Lists.
when building the nested list every <li> element should contain a <div> with a small icon and a css-style behind.
here is my code:
[Code]....
this way the result in the browser shows the name of every "aNavItem" but there are no icons. if i put the line to set the inner text of the div BEFORE adding the "imgMove" to it both things are shown - the name of the element and on the right the icon
the problem is that i want the icon to be on the left and then the text, but there is no icon at all with the code above (it looks like the setting of the inner text overwrites the already added image-control in the div-tag)

I've got this web control that I've been dynamically adding controls to but now the requirement is to add an ordered list around the controls.
To render the controls I add the controls to ControlsCollection
[code]...
How do I position the controls in the list items?
Do I need to approach the problem differently?

I've data which looks something like this.
[code]....
To convert the above data into unordered list based on depth, I'm using the following code
[code]...
But the resulting unordered list doesnt seem to be forming properly(using which i am constructing a tree).For example "Site " with id '180' is supposed to appear as a direct child of "Televisions" with id '1',is appearing as a direct child of 'Flash' with id '191' using my code.so in addition to considering depth,I've decided to consider itemid as well in order to get the treeview properly.Those rows of the table with itemId not equal to null are not supposed to have a child node(i.e.,they are the leaf nodes in the tree) and all the other nodes can have child nodes.
Update:
The 'itemid' column refers to the id of an item which is present in another table.This column just in identifying if an item has any sub items(i.e., 'name' in my data in this case has any other unordered lists under it).

i m new to asp.net 3.5 linq and dnt worked much on generics.i m using IEnumerable to return set of results.i m binding this IEnumerable type method directly to datagrid source then it works fine.But i dnt knw how to iterate through this collection??Same way i m using List<String> to return columns like this
public List<String> FindImageData()
{
List<String> lst = new List<string> { "" };
ISingleResult<Usp_Patient_Radiology_DisplayResult> imagedata = objimagedata.Usp_Patient_Radiology_Display(p_PatientID);
foreach (Usp_Patient_Radiology_DisplayResult h in imagedata)
{
string Imageid = Convert.ToString(h.ImageId);
string imagefilename = Convert.ToString(h.imagefilename);
string history = Convert.ToString(h.history);
string imagetype = Convert.ToString(h.imagetype);
string oprposundertaken = Convert.ToString(h.oprposundertaken);
string patientposition = Convert.ToString(h.patientposition);
string report = Convert.ToString(h.report);
string xfilmorn = Convert.ToString(h.xfilmorn);
lst = new List<String> {Imageid,imagefilename,history,oprposundertaken,patientposition,report,report,xfilmorn };
}
return lst;
}
but at front end again i dnt knw how to iterate through it.it returns only single row??
with dataset it was quiet easy to navigate but with linq to sql navigation through generic collections is tough.

I need to iterate through a server share and list every file within every folder and write each file name with all of its attributes into a database table.I assume that using the FileInfo class and all of it's properties (CreationTime, DirectoryName etc etc) is the best way but I have no idea of how to start.I'm starting to create a web app

As I iterate through a DataTable object, I need to check each of its DataRow objects against the items in a generic string List. I found a blog post using the List's Find method along with a delegate, but whereas that example has a separate class (Person), I'm attempting something like the following using an instance of the string object:
// My definition of the List object.
List<string> lstAccountNumbers = new List<string>();
...
// I populate the List via its Add method.
...
foreach (DataRow drCurrentRow in dtMyDataTable.Rows)
{
if (lstAccounts.Find(delegate(string sAccountNumber) { return sAccountNumber == drCurrentRow["AccountNumber"]; })
{
Found_DoSomething();
}
else
{
NotFound_DoSomethingElse();
}
}
However, with this syntax I'm receiving "Cannot implicitly convert type 'string' to 'bool'" for the if block. what I'm doing wrong and how best to accomplish what I'm trying to do?

I have an ASP.NET webservice method that returns a generics list (List'<'Construct>) serialized as JSON, using code such as this:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class TestService : System.Web.Services.WebService {
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string GetOccupationListJSON(int SOCLevel)
{
Construct NewConstructList = new ConstructList();
DataContractJsonSerializer serializer = new DataContractJsonSerializer(ConstructList.GetType());
MemoryStream ms = new MemoryStream();
[Code]....
I assumed (from looking elsewhere) that accessing the JSON data through the index would provide me with access to the underlying object at that index, so that I can then work with it to access its properties.
However, when i=0 and I do var Construct = data[i]; I get the character at the i position of the data array ([), and in the next iteration I get the second character ({). So clearly I am accessing the elements of a string array rather than the JSON data object.How do I make sure that the data returned by the webservice gets into proper JSON format, so that I can iterate through the object elements within it?

I am wondering if MVC offers a handy function to iterate through all areas. I know I can search the sub-directories of Areas to achieve this. I am just curious.

I have a section of a form that I need to handle differently from the rest of form results. In the section that needs special handling I need to iterate over 3 form fields that have the same name. They have to have the same name, I can't change it. The section of the form I am referring to looks something like this:
<td><input name="Color" size="20" value="" type="text"></td>
<td><input name="Color" size="20" value="" type="text"></td>
<td><input name="Color" size="20" value="" type="text"></td>
Using C# I try something like this:
I try to handle it like this:
int i;
for (i = 1; i <= Request.Form["Color"][i]; i++)
{
colorName.Text += Request.Form["Color"];
}
Which leads to the following exception:
System.NullReferenceException: Object reference not set to an instance of an object.
How should I be handling form fields with the same name?

public String Str2;
private String Str3;
public String Str4 { get { return Str3; } }
public TestClass()
{
Str1 = Str2 = Str 3 = "Test String";
}
}
Is there a way (C# .NET 2) to iterate through the Class 'TestClass' and print out public variables and attributes?

I have an html table in an aspx page (C#) that has columns like
1.CheckBox 2.Text 3.Text 4.TextBox
I want to iterate through the table one row at a time and process (run a stored procedure based on column2) based on whether the checkbox is checked or not. How will I be able to do that?

I have a Telerik RadGrid with a GridTemplateColumn that contains a checkbox, as follows:
<telerik:GridTemplateColumn HeaderText="MINE" UniqueName="MyTemplateColumn">
<ItemTemplate>
<asp:CheckBox id="MyCheckBox" runat="server"></asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this:
