I got a request to add this form to a asp.net control.
I want to use asp.net text box and button to submit the info to the form. (because I have special controls to match the look and feel).
this is the form:
<form name="ccoptin" id="signup" action="http://visitor.r20.constantcontact.com/d.jsp"
target="_blank" method="post">
<input type="hidden" name="llr" value="yyyyyy">
<input type="hidden" name="m" value="xxxxxx">
<input type="hidden" name="p" value="oi">
<label>sign up for new services and promotions:</label>
<input type="text"name="ea" value="" class="text" />
<input type="submit" id="iframe" class="submit"
name="go" value="submit" />
</form>
can this be done?
yes, you can use asp.net Textbox control for html input control and you can put the same styling. e.g.
<asp:TextBox ID="ea" CssClass="text" runat="server"></asp:TextBox>
Button control for html submit button e.g.
<asp:Button ID="iframe" CssClass="submit" runat="server" Text="submit" />
For your input type hidden, you can use asp.net HiddenField Control
<asp:HiddenField ID="llr" runat="server" Value="yyyyyy" />
Yes it can be done . On browser side ASP.NET controls get converted in to HTML even if you use the asp.net button.
Drag and drop asp.net button from toolbox and put attribute id , cssclass , name , text . It will get converted in end to HTML as expected
<asp:Button id="iframe" cssclass="submit"
Text="Submit" runat="server" />
Yeah. You have to consider these notes:
If you want to use ASP.NET controls, you should add runat='server' attribute to your form element. It's because ASP.NET controls (AKA server controls) while rendering check to see if they are get rendered in a server form (VerifyRenderingInServerForm method).
<asp:Hidden control is your replacement for <input type='hidden'
<asp:TextBox control is your replacement for <input type='text'
<asp:Button control is your replacement for <input type='submit'
All of your server controls should have runat='server' attribute
ASP.NET only allows for one form with runat=server, and all of your server controls have to be within a form with runat=server. Nesting forms isn't advisable.
See reference on form nesting:

You'll need the form in a different document object - maybe host it in an iframe and conver the mini-form to an ASPX page that you load into the iframe ...

In my asp.net website I have created a user control called GlobalHeader.ascx to make header content consistent throughout the website and put a text box control for search functionality as given below:
<div style="display:none;">
<form id="sample"></form>
</div>
<div>
<form id="cse-search-box" name="cse-search-box" method="get" action="/Search Results.aspx">
<input type="hidden" name="cof" value="FORID:11;NB:1" />
<input type="text" name="q" id="q" class="search-txt" onfocus="if(this.value=='Search')this.value='';" onblur="if(this.value=='')this.value='Search';" value="Search"/>
<input type="submit" name="sa" value="Search" class="search-iocn" />
</form>
Now in child page I'm having a drop-down control having AutoPostBack=true and OnSelectedIndexChanged="DrpdwnListSelectedIndexChanged" i.e. on item change event DrpdwnListSelectedIndexChanged is fired and and show some data just under drop-down list. BUT this functionality is ONLY work when I remove search functionality from Header user control.
<asp:DropDownList runat="server" ID="drpdwnList" AutoPostBack="True" OnSelectedIndexChanged="DrpdwnListSelectedIndexChanged">
</asp:DropDownList>
This means form tag preventing drop-down list AutoPostBack functionality to work.
Why so?
How can I make both functionality work together?
Interesting thing is that If I remove <form id="sample"></form> from top search functionality doesn't work.
Thanks
I have a form with 2 Text Boxes (along with other controls). Both of them have TextChanged Event. I'm using Tab Key to go from one Control to another.
After entering some value in the first TextBox and then pressing Tab, the focus is not going to Second TextBox.
I'm using TextBox2.Focus();
But this is not working.
Your Code is not useful for me. My TextBox does have OnTextChanged Event. I implemented TabIndex, but this is not working after PostBack.
Why to do server side code when you can handle it with plain html property tabindex
Plain Html Code
<span>2</span><input type='text' tabindex="1" /><br/>
<span>1</span><input type='text' tabindex="3" /><br/>
<span>3</span><input type='text' tabindex="4" /><br/>
<span>4</span><input type='text' tabindex="2" /><br/>
ASP.NET Code
<asp:TextBox ID="txtField1" runat="server" tabindex="1" />
<asp:TextBox ID="txtField2" runat="server" tabindex="2" />
For working demo see here
I have the following html:
<html>
<body>
<form runat="server">
Name: <input type="text" name="name" />
<br />
<input type="submit" name="submit" />
</form>
</body>
</html>
How do I retrieve the value in the "name" textbox posted back to the webserver to manipulate in ASP.NET WebForms?
(I know about the ASP.NET built-in controls and the possibilities with them, but I am looking for a "clean" solution without the use of built-in ASP.NET controls)
If you can't, or don't want to use asp.net textboxes, then you can retrieve the name of a regular html textbox like this:
string nameTextPosted = Request.Form["name"];
Just note that textboxes created in this manner will not automatically persist their values across postbacks like asp.net textboxes will.
Simplest solution would be to turn it into a server-side component and access it by it's name. e.g.
<asp:TextBox Id="Name" runat="server"></asp:TextBox>
...
string name = Name.Text;
Unless you have other reasons not to use a component, you'd only be making things much more difficult on your part for no justification.
ASP.net includes Html server controls for backward compatibility for just someone like you fond of html. make your html tags server controls by adding the runat="server" and id properties and you are able to access them inside your server side code with their id.
<form runat="server">
Name: <input type="text" name="name" id="name" runat="server" />
<br />
<input type="submit" name="submit" id="name1" runat="server" />
</form>
Now after this you can control their behavior:
name.Value="Hellow World !"
You have to add id and runat="server" in each control. like this :
<input type="text" name="name" id="name" runat="server" />
Its better to use asp:TextBox like this :
<asp:TextBox ID="name" runat="server"></asp:TextBox>
I'm having some real problems with a group of HTML Radiobuttons when I try to pass the selected values back and forth between JavaScript and ASP.NET.
<input type="radio" id="radio1" name="markerSel" value="1" checked=true />
<input type="radio" id="radio2" name="markerSel" value="2" />
<input type="radio" id="radio3" name="markerSel" value="3" />
To begin with, the form loads with these radiobuttons and a user selects a value and submits the ASP.NET form. To get the value of the selected option on the server-side I have tried;
string selVal = Request.Form["markerSel"];
//always returns "1", regardless of the selection made.
And also tried ASP.NET's FindControl method (recursively too), and I just get null.
I want to be able to set the value of this radiobutton group via JavaScript and Asp.NET and be able to read from both environments.
Any help would be appreciated.
Thanks
Is there a reason why you don't use ASP.NET radio buttons instead of <input type=radio />?
If you use
<asp:RadioButton id="radio1" runat="server" Checked="true" />
<asp:RadioButton id="radio2" runat="server" />
<asp:RadioButton id="radio3" runat="server" />
You will be able to access them server-side by doing this.radio1.Checked
If you want to access your elements via javascript, you can do a document.getElementById('radio1') and you will get the DOM element that way.
If you want to use jQuery, you can access the radio buttons with
$('#radio1')
If you want to test if the radio button is checked, you can use
if ($("#radio1").is(':checked')) {//...
hmmm... I would try changing the line to:
string selVal = Request.Form("markerSel");
How this code should be (asp.net standard)?
<label for="jobno">Job#</label>
<input id="TextBox_JobID" name="jobno" runat="server"/>
<input type="button" value="Show Job" class="fbutt"
id="Button_showJob" onserverclick="Button_showJob_ServerClick"
runat="server" />
</p>
<p>
<asp:Label ID="Label_error" runat="server" class="error"></asp:Label></p>
I think the for attribute is not ok, or not written in correct way?
The value of the for attribute must match the id of a form control (such as an input element or a select element), not the name.
As the textbox is marked runat="server", I would suggest using the ClientID property of the control:
<label for="<%=TextBox_JobID.ClientID%>">Job#</label>
Then if you use master pages/user controls etc, you can be sure it will always contain the right value.
It should probably read
<label for="TextBox_JobID">Job#</label>
