is it possible to create a HTML Definition's List in the codebehind? I'm trying to pro grammatically generate the following HTML:
<dl style="overflow: hidden; font-size: small;">
<dt style="float: left; width: 200px; clear: both; text-align: right; margin-left: 15px;">Apple:</dt>
<dd style="float: left; width: 90px; margin: 0px 0px 8px;">Fruit<br>Red<br></dd>
</dl>
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 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."}"
How do I create an ASP.Net MVC Helper for an Html.Label which takes in attributes? Currently when I define an Html.TextBox I am able to pass in a list of attributes. Sort of like below:
new {disabled="disabled", @class="pcTextBoxWithoutPaddingDisabled"})%>
However, it does not look as though the Html.Label has this feature. As a result, I have to define my labels using the label tag. Sort of like below: <label class="pcLabelBlackWithoutPadding"> I would like to be consistent I how my Html element get created. So, how do I create an Html.Label that will take in a list of attributes?
Is it possible to dynamically create a web page according to database definition and that page can post data back from dynamically created controls?

I have some markup on a page which I need to move to a code behind and I'm not quite sure how to do it
An example is this
<asp:DropDownList ID="YearList" runat="server">
<asp:ListItem Value="1940" Title="1940" />
<asp:ListItem Value="1950" Title="1950" />
<asp:ListItem Value="1960" Title="1960" />
<asp:ListItem Value="1970" Title="1970" />
Would the codebehind become
With YearList
.Value(0)="1940"
.Text(0)="1940"
End With

<HTML>
<Head>
</Head>
<Body>
<div id="div1" runat="server"> My Name is Guvera </div>
</Body>
</HTML>
In the above HTML i need to take a string "My Name is Guvera" using Asp.Net code.
In a C# codebehind, i am calling a web service that returns an HTML blob that i need to stick in an IFRAME. I suppose that i can write it to a temporary file and point the IFRAME src to that, but is there a way to either (a) write the string to the IFRAME directly, (b) point the IFRAME src to the string somehow (maybe with streams), or (c) some other way? I want to avoid writing this string to a file.

I have an asp.net page where i have the below markup.Basically this markup is generated from codebehind by reading records from a table and looping thru them.For each record in table,there will be a div block. Basically this form is to read/show settings for a user.The settings entries are stored in a table.
<div id='divContainer' runat='server'>
<div id='div1' runat='server'>
<table>
<tr>
<th>Name</th>
<td><input type='text' id='txtName1' value='something' /></td>
</tr>
</table>
</div>
<div id='div2' runat='server'>
<table>
<tr>
<th>Domain name</th>
<td><input type='text' id='txtName2' value='something' /></td>
</tr>
</table>
</div>
<div id='div3' runat='server'>
<table>
<tr>
<th>URL</th>
<td><input type='text' id='txtName3' value='something' /></td>
</tr>
</table>
</div>
<div id='div4' runat='server'>
<table>
<tr>
<th>Some other value is enabled ?</th>
<td><input type='checkbox' id='chk4' /></td>
</tr>
</table>
</div>
</div>
The id's of each input element will be unique. Now in codebehind i want to read the values of each input elment to save the changes user made.How can i read the elements here ? Since the mark up is generated in codebehind as a string and appended the the INNER HTML of the external div,I cant read values like we do for a control which we drag and drop in the IDE.
I'm interested to hear from other developers their opinion on an approach that I typically take. I have a web application, asp.net 2.0, c#.
What I usually do to write out drop downs, tables, input controls, etc. is in the code behind use StringBuilder and write out something like sb.Append("
I don't find myself using to many .net controls as I typically write out the html in the code behind. When I want to use jQuery or call JavaScript I just put that function call in my sb.Append tag like sb.Append("td...onblur='fnCallJS()'.
I've gotten pretty comfortable with this approach. For data access I use EntitySpaces.
I'm just kind of curious if this sort of approach is horribly wrong, ok depending on the context, good, time to learn 3.0, etc. I'm interested in learning and was just looking for some input.
Edit
After reading the comments here it sounds like I should take a look at MVC. I've not done that yet. The only hesitancy in doing so is that the existing project is just that, existing. There is a lot of code already done the way I explained and it is hard to imagine what would be involved in changing it, advantages of doing so, and just learning what that would take.
The other thing I'm taking away from the comments is that my code behind should really not include much of the sb.Append code, whereas now it is filled with it in numerous functions. To me it is not messy but that is because I know what each function does and can look at it and see, oh that writes out x, y, and z.
It's not uncommon for me to just have a div on the .aspx part and then build up the .innerHtml of that with the StringBuilder in the code behind.
i have this string:
string foo = "<p>temp</p>";
how can i show it on my page without using Response.Write(foo)
I am generating a dropdown list in codebehind and cannot get the selectedindexchanged event to fire automatically. It works fine when put directly into the ASPX page, but I need it to be in the codebehind.
This doesn't work -
[code]....
I have a listview which I would like to fill with self created user controls.But the problem is that the properties in the user control is not set. The usercontrols are displayed but the property values I enter is not set. Why is that?
Here is the aspx code.
[code]....
in my proj i have a grid view which consists of name and droppown list as shown below:
<asp:GridView ID="gvJobs" runat="server" AllowPaging="true" AllowSorting="true" AutoGenerateColumns="False" OnRowDataBound="gvJob_RowDataBound" OnRowCommand="gvJobs_RowCommand" >
<Columns>
<asp:TemplateField HeaderText="Jobs" SortExpression="name" HeaderStyle-HorizontalAlign="Left">
[Code]....
when i click the dropdown list it is postbacking(since i made auto postback=true). on that time i am unable to get the selected value from dropdown list.
I have a span control which I am filling using Jquery. At the page load I want this span say id1 to be invisible and depending on some conditions I am making it visible via jquery itself.
When I make id1 runat = server and try to access id1 from codebehing, then I get an error in Jquery.
Hence I need a way to make id1 invisble at the load time itself.
I have already set id1 = invisble in HTML, But still I see this control on the page till the time jquery fills the entire data.
I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
string bgStyle = "background-color:" +theme.searchTextHeaderColor +";";
OwnerSearchHeader.Attributes.Add("style", bgStyle);
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.
I want my codebehind to dump a very large set of JS into the ASPX page. This is required, as I can't use external JS code for this component, and the code is also unique to each customer. Is it possible to do this from codebehind? I know how to set the value of text boxes etc. (.Text/.Value = xxx) but I can't see how I can just 'dump' code straight onto the page.

I'm using VS 2008 and can't seem to get intellisense to reconise Public variables declared in my codebehind.I start a new ASP.NET Web Application project, named something other than "WebApplication1". In my default.aspx.vb codebehind, I declare, say, "Public MyValue As Integer = 10", at the class level of course.Then, in my default.aspx page, within the body tag, I type "<%= myvalue %>"No mater what I try, it refuses to recognise "myvalue" as a valid variable name, however the code DOES compile and runs perfectly. Everything else seems to work fine.
View 3 RepliesI would like to create an ASP.Net page without all the codebehind and designer stuff. Basically I want to go back to ASP classic, but keep the CLR and Base Class Library that makes .Net oh-so-wonderful. I'd like just a page something like this:
<html>
<body>
<div>
<%
int customerID = Request.QueryString["CustomerID"];
//Customer and DataAccess classes come from an extenal assembly
Customer customer = DataAccess.GetCustomer(customerID);
%>
You asked for Customer with ID: <%=customerID;%><br />
Name: <%=customer.Name;%><br />
Phone: <%=customer.Phone;%><br />
</div>
</body>
</html>
However there seem to be some problems with that. The Request object is only available from within a Page object. I wish to completely delete the codebehind and designer pages. No intellisense Anything else I should be aware of before I get too deep into this? No idea how to start pulling in extenal libraries
