I have several checkbox controls on my web form that are not server controls (runat="server") How can I access these controls form my C# code? Can this be done with document.GetelementById from the server side using C#? Or some other technique?
I am not allowed to make these server controls (runat=server) because of a requirement.
I am trying to make a PhoneNumber Control. I inherit from Composite Control. It contains 5 controls : 1 Label (Text to show before), 3 TextBoxes(area, prefix and line) and a Custom Validator. What I want to happen is the validator to validate the control is belongs to in two ways: 1. that the field is required and 2. That the COMBINED text of the 3 textboxes is 10 digits. I believe i can accomplish this with the expression ^d{10}$. Now I have it about halfway working, it will validate the control using client-side embeded validation on a submit click, however I need the control to validate as soon as the text of any of the boxes changes. I know this is done on the aspx page by using a Custom Validator -> specifying client and server side validation functions -> and then at end of page doing ValidatorHookupControlID(control, va lidator). My goal is to do all of this within the control to clean aspx code and make it more reusable.
When a .NET server control is rendered in a browser it is rendered as a html control. Then how a browser differentiate between a server control and a html control. If the two control rendered as same then how server side events fire for a server control? If u say by using runat="server" attribute then also we can add runt="server" for html controls to work at server side... so then how these are recognized?
i'm attempting to set regular html checkbox's checked value based on if a master asp checkbox is checked or unchecked.

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.
I have bunch of HTML code I am using to make rounded edge boxes on my controls. Is there a way to take this code and turn it into some kind of control or something so I do not have to keep pasting 10 lines of HTML code around everything I do?
One additional thing to note, the number HTML tags used inside the inner most DIV will change depending on where I use it in my site. So in some cases I will only have 1 tag and 1 tag but in other cases I could have 1 tag, 1 tag, 3 tags, and a HTML table. How can I make that work?
How can I get gridview HTML textbox value in .aspx.cs code?? E.g. : <input id="Frequency" name="customerName" type="text" style="width: 44px" />If i use the bellow code ,Then i can get the value on selectedIndex event.
string n = String.Format("{0}", Request.QueryString['customerName']);
I want to use bellow syntax.TextBox_Label1 = (TextBox)e.Row.FindControl("Frequency"); i don't want to user the runat="server" on HTML control .From Gridview i need to call a popup,Popup return a value ,I use the bellow code on javascript to do that

I need to validate a textbox to ensure the submit date is older than Today. I wanted to use a CompareValidator to do that, but unfortunately the following code doesn't work:
For reasons outside my control I have a table containing input and select fields built using regular HTML with the runat="server" attribute (as opposed to standard ASP.NET controls). I am trying to set a value to be selected when the page is loaded based on values being passed from the Session (again, factor outside my control).
Setting the Selected property of the list item does nothing and doesn't select the item in question. How do I achieve this?
the Select portion doesn't work, although it gets executed on the proper item. Should this code be called in a specific event? I believe it's being called in Page_Load; should it be called in Pre_Render instead?
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="test.ascx.cs" Inherits="UserControls_test" %> <p id="XXX">aaa</p>
and here is the contents of my test.ascx.cs file:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class UserControls_test : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { this.XXX.InnerHtml = "BBB"; } }
I get an error when I refer to the id, "XXX" (underlined above) in code behind which reads: 'UserControls_test' does not contain a definition for 'XXX' and no extension method 'XXX' accepting a first argument of type 'UserControls_test' could be found (are you missing a using directive or an assembly reference?)
I have tried XXX.InnerHtml and I have tried this.XXX.InnerHtml and get same problem.
How do I successfully refer to ID'ed HTML elements in code behind?
I am struggling with something that I guess should be standard practice really. I have a number of user controls that use some JQuery plugins. I do not really want to link to the extra CSS and JS files from my main masterpage as this would cause extra load to the user the first time they hit the site, (admittedly it would only be the once), so I was just putting them links into the top of the user control. Then I looked at my source HTML, not nice! Even worse for controls that repeat multiple times on a page.
So I was thinking is there a way of injecting them into the Head of the page when they are needed from the User Control. For that matter is there a way of doing it to the footer for JS stuff?
I need to create a reusable custom control,which is like a form containing a listbox and some fields.The fields can be either textbox or combobox as needed for different applications,which can be selected on the property of the form onwhich page that i am using it,also i needed to specify the number of fields in that property.And also need place 3 buttons below for edit and delete the selected item in the listbox and a button to save.Data will be binded from the database as needed for different applications.
tell me with code how to create it using asp.net server control in C#.
If i've the button outside an update panel (basically i'm using RadAjaxPanel by Telerik) it is working fine. But when the button is inside an ajax panel, even if i click OK for deleting the records the server side code is not called.
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?
