I have a project that I am working on in VS2005. I have added a WebBrowser
control. I add a basic empty page to the
control
private const string _basicHtmlForm = "<html> "
+ "<head> "
+ "<meta http-equiv='Content-Type' content='text/html; charset=utf-8'/> "
+ "<title>Test document</title> "
+ "<script type='text/javascript'> "
+ "function ShowAlert(message) { "
+ " alert(message); "
+ "} "
+ "</script> "
+ "</head> "
+ "<body><div id='mainDiv'> "
+ "</div></body> "
+ "</html> ";
private string _defaultFont = "font-family: Arial; font-size:10pt;";
private void LoadWebForm()
{
try
{
_webBrowser.DocumentText = _basicHtmlForm;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
and then add various elements via the dom (using _webBrowser.Document.CreateElement). I am also loading a css file:
private void AddStyles()
{
try
{
mshtml.HTMLDocument currentDocument = (mshtml.HTMLDocument) _webBrowser.Document.DomDocument;
mshtml.IHTMLStyleSheet styleSheet = currentDocument.createStyleSheet("", 0);
TextReader reader = new StreamReader(Path.Combine(Path.GetDirectoryName(Application.ExecutablePath),"basic.css"));
string style = reader.ReadToEnd();
styleSheet.cssText = style;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Here is the css page contents:
body {
background-color: #DDDDDD;
}
.categoryDiv {
background-color: #999999;
}
.categoryTable {
width:599px; background-color:#BBBBBB;
}
#mainDiv {
overflow:auto; width:600px;
}
The style page is loading successfully, but the only elements on the page that are being affected are the ones that are initially in the page (body and mainDiv). I have also tried including the css in a element in the header section, but it still only affects the elements that are there when the page is created.
So my question is, does anyone have any idea on why the css is not being applied to elements that are created after the page is loaded? I have also tried no applying the css until after all
of my elements are added, but the results don't change.
