Web Forms :: How To Highlight The Current List Item In The Unordered List
Mar 25, 2010I 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.
AJAX :: Using Accordion With An HTML Definition List Or Unordered List?
Jun 8, 2010I 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.
Is It Possible To Iterate Through An Unordered List
Jun 21, 2010Is 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.

Web Forms :: Dynamic Unordered List With HtmlGenericControl?
Jun 24, 2010i 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)

Converting Hierarchical Data Into An HTML Unordered List Programmatically Using C#?
Mar 16, 2010I'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).

Web Forms :: TreeViewcontrol And OnBeforeUnload?
Sep 28, 2010In one of my applications, i created the left navigation menu using treeviewcontrol. Each and every node in the treeview is calling a URL in the application.Content pages are dynamically created ASP.NET controls.There is no submit or save buttons in these pages. When the user finished entering the data and go to another link in the tree structure, the data need to be saved in the database and go to the next link.I tried this using OnBeforeUnload and Document.form1.submit, the aspnet form is not submitting, so there is no postback. I also tried __dopostback method call from the javascript. Still not able to get it working.

View 10 RepliesWeb Form Render Engine Outputs A Control Tree / Looking For Info On Render Logic.
Feb 12, 2011I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

Jan 21, 2010I am building a little app to upload a picture and various downloads for different file types for the photos, but I also need be able to select the catergory they will go into.

MVC :: Render The Table For The Search Results As Long As The User Hasn't Pressed The Search Button?
Jan 18, 2010As a newbie coming from a Java background with tag libraries I wonder if there is a simple possibility to render areas depending on backend values.For example if I have search form I do not want to render the table for the search results as long as the user hasn't pressed the search button. Of course I can iterate over the model containing an empty list but this does not allow to suppress rendering the whole table.Using web forms I would just control the visibility of the affected tag(s) in the code behind file but how do I do this with ASP.NET MVC?Can I use a partital view for a case like this? But I think I would have the same problem. How can I determine if a partial view is rendered (e.g. the whole result table with header)?
View 7 RepliesCreate HTML Table From A List In C#?
Jan 26, 2011I am trying to get some values from a List and then create a html table with this data but I can't get it to work properly.
I have:
HtmlTable table = new HtmlTable();
HtmlTableRow row;
HtmlTableCell cell;
foreach(var item in Name)
{
row = new HtmlTableRow();
foreach(var familyName in item.familyName)
{
cell = new HtmlTableCell();
cell.InnerText = item.familyName.ToString();
row.Cells.Add(cell);
}
foreach (var givenName in item.givenName)
{
cell = new HtmlTableCell();
cell.InnerText = item.givenName.ToString();
row.Cells.Add(cell);
}
table.Rows.Add(row);
}
this.Controls.Add(table);
When I step through the debugger I can see that row.Cells.Add(cell) contains the family name in the first loop and given name in the second loop but then something seems to be wrong and I can't get the table to show up on the page with this data.
When I check the table.rows.add(row) it says that "base {System.SystemException} = {"'HtmlTableRow' does not support the InnerText property."}"

AJAX :: Reorder List Isn't Working With My Db Table?
Jun 20, 2010I did the tutorial for the ReorderList on the asp.net site: http://www.asp.net/ajax/tutorials/drag-and-drop-via-reorderlist-cs and everything works perfectly. But for some reason when I switch out the references and use the same code for my db table the changes aren't saving. In other words when I use the db table called 'AJAX' that I created based on the tutorial everything works perfectly, but when I use it on my table ('projects') the changes don't save to the db. I can't think of anything in the db that would be causing this to happen.
Here's my code:
//This works
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="asm" runat="server" />
<div>
<asp:ReorderList ID="rl1" runat="server"
SortOrderField="position"
