foreach (HtmlElement HtmlElement1 in webBrowser1.Document.Body.All)
            {
                if (HtmlElement1.Document.GetElementById("a").GetAttribute("href") == "index.jsp") 
                {
                    textBox6.Text = "Ok"; 
                }
            }

if you know an exact string to look for you can do the following: # HTMLDocument objHtmlDoc = (HTMLDocument) webBrowser1.Document.DomDocument; # /*webBrowser1 is the WebBrowser Control showing your page*/ # string pageSource = objHtmlDoc.documentElement.innerHTML; //then if ( pageSource.Contains(@ a href = index.jsp >Succesfully Posted a > ) textBox6.Text = Ok;

Thanks a lot guys for your asnwers.. Firstly roei i am using WebBrowserDocumentCompletedEventArgs function. when i am loading the first html page the codes are working correctly. But when i click a button and visiting another html page the codes are not working properly. I mean i arrange my codes for finding tag on second page (after clicking) but i couldnt find tags correctly on second page. My all codes are below. Are there any problem? private void page_success(object sender WebBrowserDocumentCompletedEventArgs e) { webBrowser1.Document.Body.SetAttribute(background #000000); webBrowser1.Document.Body.Style = background:#7fffd4; foreach (HtmlElement htmlEl in webBrowser1.Document.Body.GetElementsByTagName(a)) { if (htmlEl.GetAttribute(href) == index.jsp) { textBox6.Text = OK; } } }

well 2 things first off about your question if you are on page_success event then you have the pageComplete event args so you know your page completed the load about the answer above this one it will work but might jump the msgbox more then once :-)

This is solution for your problem I think :) foreach (HtmlElement htmlEl in webBrowser1.Document.Body.GetElementsByTagName(a)) { if (htmlEl.GetAttribute(href) == index.jsp) textBox1.Text = OK; }

Firstly thanks for your answer roei. But when i try you code like below its getting that error The type or namespace name 'HTMLDocument' could not be found (are you missing a using directive or an assembly reference?) I added the namespaces below; using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Data.OleDb; using System.Drawing; using System.Data.Common; using System.Linq; using System.Text; using System.Windows.Forms; using System.Text.RegularExpressions; I am using  private void page_success(object sender WebBrowserDocumentCompletedEventArgs e)  function. It can be a problem?
