How do you set the value of an input element programmatically through CSharp?

Question

Hi I'm trying to automate my IE to enter a website, but the problem is that the input elements do not have an HTML ID attribute! For instance:

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

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

thank

Answer 1

Add the following attributes to your input tag: runat="server"andid="someId"

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

Then the server side:

user.Text = "sample text";

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 that it will work without an attribute runat="server"

I know this is a little late, but here is an alternative to the jquery method.

, IE -. , .

-

HtmlElementCollection inputs = browser.Document.GetElementsByTagName("input"); >

. input.GetAttribute("name").Equals("user") >

input.SetAttribute("value", "MyUserName"); >

, " #", jQuerify , javascript , . WebBrowser, , .

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

jQuerify

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

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