Question

I try to fill up a “Select” element in my HTML while it’s open on my own browser in a C# application. So i did this:

DataTable dt = new DataTable();
HtmlElement States = webBrowser1.Document.GetElementById("Select1");
da.Fill(dt);
States.InnerHtml = "";
for (int i = 0; i < dt.Rows.Count; i++)
{
    string head = String.Format(@"<option Value=""{1}"">", 
        dt.Rows[i]["Code"].ToString());
     string body = String.Format("{0}</option>", dt.Rows[i]["Name"].ToString());
     string tag = head + body;

     States.InnerHtml =tag;
}

But surprisingly when I expect to result be something like this

< option Value="aNumber">testString<\option>

I see this:

testString<\option>

I saw the same problem here when I was struggling to write the expected string. Finally I inserted a blank space to the second char on my string. Thus I worte < option> instead of <option> in here. I did same for that string which I want to pass to the InnerHtml property of my element. But unfortunately it didn’t work.

Shouldn’t this

string head = String.Format(@"<option Value=""{1}"">", 
        dt.Rows[i]["Code"].ToString());

be this?

string head = String.Format(@"<option Value=""{0}"">", 
        dt.Rows[i]["Code"].ToString());
