I am trying to pass a parameter value via the URL and it works for most values unless the value contains parenthesis. I have tried the backslash () to escape them but it doesn't appear to work.
Here is the URL
http://<server>/OpenDocument/opendoc/openDocument.aspx?sViewer=html&sDocName=<DocName>&sType=rpt&promptex-<ParamName>=VALUE_CONTAINING_(PARENTHESIS)
