C# - Persisting Html Control Content With Runat Server Tag

Jan 11, 2011

I have this problem - I'm working on an ASP.NET AJAX-application on a server without .net 3.5 which means I can't use ListView (BOO!).

I decided to simply do the ugly way of making a table and giving the tbody an ID and a runat server tag, and put HtmlControls inside from the codebehind (btw - this is a usercontrol, in case it makes a difference).

This all works fine - until the page does a partial postback - and all the elements disappear, since the tag is runat server I assume it requires to be repopulated in the page load.

Is there no way to actually persist the data on partial postback? And only have the content of the control change when I say so in the back end?

I guess I could save the content in a session object upon populating the control, and just repopulate in the Page_Load with the session object - but I was hoping there was a better way to do this?

Custom Server Controls :: Create C# Controls On Server Side For Posted Data That Had No Runat=server

Feb 4, 2010

HOWTO 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.

Run Server Side Function On Dynamic HTML Control?

Jul 28, 2010

I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages:

CmsContactUsContent += string.Format("
"<input type='image' value='delete' id='del{8}' runat='server' onClick='DeleteItem' img src='/MaromyDotNet/img/AdminIcons/note.png' style='width:16px;'/>" +
"</div>" +
"<div style='clear:both'></div></div>", message.ContactMessageId);

There is a Class called ContactMessage and I'd like at each iteraion to allow the user to delete the current message through this function:

public void DeleteItem(object sender, EventArgs e)
{
int idToDelete = 41;
BLLContactMessage.deleteMessageById(idToDelete);
}

However, the event does not fire.

Web Forms :: WebControls Versus HTML Controls (with Runat=server)

Apr 14, 2010

I 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 - Runat=server Removes Carriage Returns From Head Tag?

Jul 2, 2010

I'm new to .net, and I've noticed that when viewing my HTML source code generated by a .net application the carriage returns are removed from the head tag when it has runat="server" attribute on it.

I remove the runat="server" and the returns... return.

This really looks nasty when you have a few javascript and css files in your header because it ends up making the entire contents of the head tag 1 big line.

Just wondering if there's a way to control this or tell .net through configuration not to mangle the output?

JQuery :: How To Access Span From HTML To Codebehind Without Using Runat = Server Tag

Dec 7, 2010

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.

Web Forms :: How To Access HTML Control Value From Server-side Code

Mar 20, 2010

I have to access my html control and get its value from my server-side code. Is there anybody who could suggest how I could do it?

My html control is very simple: <input type=text>

But the thing is: I can't make it <input type=text runat=server> cause in this case my jquery functionality (datepicker) does not work.

HTML - Why Does Rewrite Relative Paths For Runat=server Anchor Controls

Mar 24, 2010

I 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.

How To Read Inputstream From HTML File Type In C# Without Using Server Side Control

Sep 17, 2010

I have the following form

<input type="file" id="upload" name="upload" /><br/>
<input type="submit" id="save" class="button" value="Save" />

When I look at the file collection it is empty.

HttpFileCollection Files = HttpContext.Current.Request.Files;

How do I read the uploaded file content without using ASP.NET server side control?

Set The Value SomeValueReturnedFromADatabase To A Control That Is Not Runat=server?

Jan 6, 2011

Its 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?

Render - Server Control Emitting Server Side Tags?

Feb 19, 2010

I'm new to writing custom ASP.NET server controls, and I'm encountering the following issue:

I have a control that inherits from System.Web.UI.HtmlControls.HtmlGenericControl. I override the control's Render method, use the HtmlTextWriter to emit some custom HTML (basically a TD tag with some custom attributes), and then call the case class' Render method.

Using the control:

<dc:Header id="header1" runat="Server" DataColumn="MemberNumber" Width="30%">Member Number</dc:Header >

The problem is that when I view my rendered HTML, the server tag is emitted to the client as well (right after the TD tag):

<dc:Header id="ctl00_ContentPlaceHolder_testData1_testData1_header1">Member Number</dc:Header>

How do I prevent this from happening?
