Converting Hierarchical Data Into An HTML Unordered List Programmatically Using C#?
Mar 16, 2010
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 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 have web form and on it I have a DataList that is grabbing some Data from a Database and displaying them as a list.However when I look at the HTML Source Code produced, it's all Tables ! <td> and <tr> !!
How can I stop this ? I want my DataList to display the data like so:
I had made a table to fill the unordered list but how to fetch that data into li and ul the table consists of home, organisation (with children as policy, employeesdetails), and so on.. How do i fill these ul and li's and children of li's with data from sqlserver2005 table?
I'm not supposed to use any asp.net built in controls like asp.net menu
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.
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 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 added a collection of data into a list box. i have another group of data with a group name.i want to add this group in to that same list box as a tree structure.
the sample list box is shown below.
item1 item2 item3 -group name group item1 gruop item 2 gruop item 3 item 4 item 5
is there any way to do this. when clicking on the group name it must be expanded within the list box and i want to manage all these elements with an index.
I'm writing an ASP.Net application (no AJAX, but maybe) and there's a requirement to have a list of companies graded under a traffic light system. I intend to have these in a collapsible hierarchical list on the Master page, e.g. Red expands to show companies, and then companies can be further expanded.
how can I keep the expanded list in the same place, with the same content visible, between page loads?
For this i am using row filter and filtering the values in the Dt and then i am binding the dt back to the ListView here i am getting the problem as "The data source does not support sorting". I am aware that i am changing the data source, but before binding the datasource manually to
dt,
i hav tried doing this to make the datasourceid null which i hav attached previously
lvSalesLayOut.DataSourceID = "";
But i am getting the error post me how to get this done programatically.
I need to convert a SharePoint List to ASP.NET, including its column filters etc.
Aside from the underlying data which will be housed in a SQL Server table, what are good control choices on ASP.NET side for this? (I'm not sure if ASP.NET Gridview will have all the necessary features.)
I want to convert my current asp.net page which will be running, to PDF when i click a button present on the page. I have buttons textboxes and text on the page. itextsharp.dll is not showing textboxs and buttons on the page its only showing plain html text.. what should i do?
