How to access html control value in code without using runat server?

Question

Here I have javascript to add html control (Input). I cannot apply asp.net control here because it is dynamically included in a java script I just want to use the input value in my code behind the page that javascript is dynamically generated.

Is there any way to get value from HTML control in asp.net.

Answer 1

Using Request.Form ["id"] `on Button_Click, you will get the html control value

string id = Request.Form["id"]

Answer 2

You can access the control without having runat="server" , which you need to execute

• The form method must be of type POST.
• The tag must have the attribute NAME. Because it is used as a key in the form of [].
• The Html control must have access in code.

Html

 <form id="form1" runat="server" > <input type="text" name="txtName" value="hidden text" /> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /> </form> 

C # code:

 protected void Button1_Click(object sender, EventArgs e) { string s = Page.Request.Form["txtName"]; } 

Answer 3

You can use the ajax post to send your data from the client to the server code. You need to write a web method on the asp.net page and in the ajax user post. here is an example

Answer 4

You can try this

get the text area.

In Head, use the java script function.

 <script type="text/javascript"> function getvalue(temp) { var imgcontrol = document.getElementById(temp); alert(imgcontrol.value); } </script> 

If you want to use the code in the code, just use the value in the hidden field and get access to it. in the warning you get the value. I hope this helps you.

thanks
