How Do You Set Value of Input Element Programmatically Through CSharp?

Question

Hello I am trying to automate my IE to log into a website but the problem is that the input elements do not have an HTML ID attribute! For example:

<input type="text" name="user" size="15" value="">

How do you program C# to insert text in this text box?

Thanks

Answer 1

add the following attributes to your input tag: runat="server" and id="someId"

<input id="user" type="text" size="15" runat="server">

then server-side you do

user.Text = "sample text";

Edit #1: then you can do something like

foreach Control c in Page.Controls
{
    TextBox t = c as TextBox;

    if(t != null)
    {
        t.Text = "sample text";
    }
}

but I'm not sure it'll work without the runat="server" attribute

Answer 2

I guess this isn't "doing it programatically with C#", but you could jQuerify the page, then run some custom javascript afterwards, to manipulate the value of the control. If you are using WebBrowser, you could call the below method to insert the scripts.

string script = "script text";
WebBrowser.Navigate(script);

jQuerify code

var s=document.createElement('script');
s.setAttribute('src','http://jquery.com/src/jquery-latest.js');
document.getElementsByTagName('body')[0].appendChild(s);

Custom code

$(document).ready(function(){$('input[type="text"][name="user"]').val('FooBar')});
