How to access to an HTML control runat server from JavaScript
How to access the HTML control values in form object, if runat="server", is not present in the HTML controls.
View 6 RepliesI 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 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?
I am using HTML control,and want to visible false from the server side with out using attributes runat="Server"
View 2 RepliesI have one html string in DB like below
<div style="padding-left: 200px; padding-top: 20px">
<div style="text-align: left;padding-top:10px">
<input id="Text1" type="text" /></div>
<div style="text-align: left;padding-top:10px">
<input id="Text2" type="text" /></div>
<div style="text-align: left; padding-top: 10px">
<input id="Button1" type="button" value="Submit" /></div>
</div>
i wan to render this in aspx page. but before this i want to all runat server to all html control in above string
like
<div style="padding-left: 200px; padding-top: 20px">
<div style="text-align: left;padding-top:10px">
<input id="Text1" runat="server" type="text" /></div>
<div style="text-align: left;padding-top:10px">
<input id="Text2" runat="server" type="text" /></div>
<div style="text-align: left; padding-top: 10px">
<input id="Button1" runat="server" type="button" value="Submit" /></div>
</div>
i'm trying make some stuffs in jQuery using asp.net. but the id from runat="server" is not the same as the id used in html.
i'm used to use this to get the id from this situation:
$("#<%=txtTest.ClientID%>").val();
but in this case. it does not work, and i'm clueless why.

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.
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?
I am facing one asp.net server side issue using vb.net the problem is i declared one html input hidden field in my page, the name is hidden1. but when i going to call that name into server side code, that time i got the below error, <b>Name "Hidden1" is not declared</b> Code below:
Default.aspx
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebApplication2._Default" %>

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.
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?
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.
In other words, why can't I do this:
<a id="projectsButton"
visible=<%= someFunctionWhichEvalsToFalse() ? false : true %>>
</a>
It seems to do nothing. I checked this by switching the false and true.

I have the following error message: "Control 'ctl00' of type 'ImageButton' must be placed inside a form tag with runat=server"
The parameter used to create the control collection must be a "System.Web.UI.Page"
Is there a property on the Page object to enable the form tag runat=server?
Here is my code:[Code]....
In the same way that I use onFocus="this.select()" for a control, I would like to use onChange="txtbox3.focus()"
How do I do that?
Okay, this may seem silly, but on an ASP.NET .ascx control, I'm trying to use:
<input type="button" runat="server" />
instead of:
<asp:Button runat="server" />
And it's not working for me. This code:
<asp:Button id="btnBuyCat" runat="server" Text="Buy Cat"
ToolTip="Click to buy a cat" OnClick="btnBuyCat_Click" EnableViewState="false" />
renders the following HTML: (ignoring naming containers btw)
<input type="submit" id="btnBuyCat" name="btnBuyCat" value="Shopping Cart"
title="Click to buy a cat" />
That's mostly fine, except I want input type="button" not input type="submit".
I tried this code:
<input type="button" id="btnBuyCat" name="btnBuyCat" runat="server"
value="Buy Cat" title="Click to buy a cat" onclick="btnBuyCat_Click"
enableviewstate="False" />
and get this HTML:
<input type="button" id="btnBuyCat" name="btnBuyCat"" value="Buy Cat"
title="Click to buy a cat" onclick="btnBuyCat_Click" />
Unfortunately the rendered button does not work. Also, I even tried input type="submit" just to check, but unless I use the <asp:Button> I can't get it to work. I'm sure it has something to do with the JavaScript.
I need to make an ajax call from my javascript and access a control on my page. Using a webmethod wont work then since it's static, do I have any other options?
View 3 Repliesmy application runs on the client side. I have to access a display on the asp page via javascript. I have the following code working properly:
ClientSript.RegisterStartupScript(this.GetType(), "allMessages", "<script>document.forms[0].tbDisplay.value='Messages'; </script>");
tbDisplay is a "text box" asp:textbox control. I need to replace de 'Messages' for avariable. so instead of printing "Messages" all the time, I can change the information on the variable prior to display the message. how to change 'Messages' to a variable.
How to wire up HTML server controls events?
I added a Input (Text) control in my web form and turned it into an HTML server control so its an instance of HtmlInputText class.
If I double click on the control It only adds a OnClick event handler method inside the script tags in the HTML doc of the web form but how to I get to handle its Serverchange event exactly? does VS.net 2008 has no ability to auto wire up the event to the control, do I have to manually wire up the event handler?
i'm extending gridview.
i've overried render method, in which i created a html table and added a html row for each data row.
