Why Use Runat="server" In Controls
Feb 28, 2011tell me why we use runat="server" in controls?
As far as i know when we use runat="server" property in a control, that control became availble in a code-behind file: .aspx.vb or .aspx.cs.

Custom Server Controls :: Create C# Controls On Server Side For Posted Data That Had No Runat=server
Feb 4, 2010HOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.
.Net Runat Server Controls Not Compiling?
Mar 29, 2011I have created a new Web project (.Net 3.5) and I've removed the original Default page in favour of creating a Master page and then recreating a Default with Master page. All worked lovely. Now, when I add my controls inside of the ContentPlaceHolder on the Default page, I get compiler errors when I try to access the controls from the CodeFile:
Error 4 '_Default' does not contain a definition for 'FirstName' and no extension method 'FirstName' accepting a first argument of type '_Default' could be found (are you missing a using directive or an assembly reference?)
My declaration of the control:
<asp:TextBox runat="server" ID="FirstName" />
EDIT
Page declaration:
<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
Code-behind:string firstname = FirstName.Text;
Web Forms :: WebControls Versus HTML Controls (with Runat=server)
Apr 14, 2010I want to know differences between ASP.Net WebControls and Html Controls (with runat="server" attribute).
I also want to know the possible scenarios where I have to (or want to) prefer Html Controls (with runat=server) in place of asp.net server controls?
In case of some good articles on web, do forward me. But dont forward me the links with differences between webcontrols and html controls, because my question intended for runat="server" attribute.
HTML - Why Does Rewrite Relative Paths For Runat=server Anchor Controls
Mar 24, 2010I have my UserControls in a ~/Controls folder in my solution:
/Controls/TheControl.ascx
If specify the following:
<a id="theId" runat="server" href="./?pg=1">link text</a>
ASP.Net seems to want to rewrite the path to point to the absolute location. For example, If the control is on [URL] the link href will be rewritten to read
<a id="munged_theId" href="../../Controls/?pg=1>link text</a>
Why does Asp.Net rewrite these control paths, and is there an elegant way to fix it?
I just want the anchor control to spit out exactly what I tell it to!!! Is that so hard?
EDIT:
I've basically done what Kelsey suggested. I knew I could do it this way, but I don't like adding markup in my code when I want something relatively simple. At least it solves the problem:
Aspx page:
<asp:PlaceHolder ID="ph" runat="server"></asp:PlaceHolder>
Code-behind:
var anchor = new HtmlGenericControl("a") { InnerText = "Previous" + " " + PageSize) };
anchor.Attributes["href"] = "?pg=" + (CurrentPage - 1);
anchor.Attributes["class"] = "prev button";
ph.Controls.Clear();
ph.Controls.Add(anchor);
As you can see by the amount of code needed for what is essentially supposed to be be a simple and light-weight anchor, it's not the most optimal solution. I know I could use a Literal but I figured this was cleaner as I'm adding more than one anchor.

Forms Data Controls :: Bind () Does Not Work When Includes Runat="server"?
Feb 2, 2010I have a FormView which contains a table and a TextBox:
<TR>
<td>CastomerName:</td>
<td>[code]....
and it works good.I changed the code to have a possibility for changing the row visibility. So, I added the row ID and runat="server". Changes are bolded:
<tr ID="RowCustomerName" runat="server">
<td>CastomerName:</td>
<td>[code]....
After the runat="server" has been added to the <TR> then Bind() does not work. It reads the field value properly but writes NULL value. So, Bind() does not work or works bad. I tested the following:
1. When runat="server" is removed, than Bind() works good. The text from TextBox control is written to the database as expected.
2. When runat="server" is set and I set a default value in the ObjectDataSource - the default value is written to the database, so it means that path form ObjectDataSource works good and it means that text from TextBoxControl is not pased to the ObjectDataSource.
3. When runat="server" is set then text from TextBox.Text is never written to the database, instead null value is written.
including runat="server" makes Bind() works bad.

C# - Using Server Variables In A Href <%= Xx %> With Runat=server?
Nov 29, 2010When I use an anchor tag on an aspx page as below,
<a href="~/pages/page.aspx?id=<%= ServervariableName %>"> test </a>
it will get the variable value correctly assigned to id but it won't route the page correctly as the ~ will not be evaluated without the runat="server" attribute on the 'a' tag. But once I add the runat server attribute, it does not evaluate the servervariable name anymore.. how this works or what I should do to take care of both?

Set The Value SomeValueReturnedFromADatabase To A Control That Is Not Runat=server?
Jan 6, 2011Its simple if I have an ASP.net page with an ASP.net linkbutton / hyperlink and I obtain a value from say a SQL Database and I store it in the label...
For example:
this.myLabel.Text = someValueReturnedFromADatabase
This is simple because it goes right to the code behind page and set the text value to the value returned from my database (aside from going into more details with data access layer, etc).
What I was wondering is what if I dont want to use an ASP.net linkbutton and I simply want to use an HTML link button (as I need to call the jquery fade function). How would I set the value someValueReturnedFromADatabase to a control that is not runat=server?
