Hi,
My idea is converting an RTF document to HTML because the rich text control offers the RTF output result.

1)You can use this article to create an advanced rich text box: RicherTextBox

2)To convert the RTF result, you can use the

"SautinSoft.RtfToHtml"

. For the trial version you can convert over 30000 words Sniff | :^)

<pre> private string GetHtmlText(string strRtfText)
        {            
            if (string.IsNullOrEmpty(strRtfText)) return "";

            string result = "";

            #region Version SautinSoft

            SautinSoft.RtfToHtml r = new SautinSoft.RtfToHtml();
            //this property is necessary only for registered version
            //r.Serial = "XXXXXXXXXXXXX";

            //specify some options
            r.OutputFormat = SautinSoft.RtfToHtml.eOutputFormat.HTML_5;// SautinSoft.eOutputFormat.XHTML_10;
            r.Encoding = SautinSoft.RtfToHtml.eEncoding.UTF_8;// SautinSoft.eEncoding.UTF_8;

            //specify image options
            r.ImageStyle.ImageFolder = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\\TempFiles";      //this folder must exist
            r.ImageStyle.ImageSubFolder = "webs";   //this folder will be created by the component
            r.ImageStyle.ImageFileName = "picture"; //template name for images
            r.ImageStyle.IncludeImageInHtml = true;//false - save images on HDD, true - save images inside HTML


            result = r.ConvertString(strRtfText);

            #endregion

            return result;
        }

fyi: SautinSoft RTF=>HTML full version which can handle > 30k words is a US $239 component, on SautinSoft's web-site.

Has the OP searched here on CP for RTF to HTML conversion ? On StackOverFlow, on Google, for other free controls ?

best, Bill

As Richard said there is another forum for WPF. However, most WPF implementations use the ~~MVP~~ MVVM pattern rather than the MVC pattern. They are similar and related but diffent. MVC is more widely used in web applications.

Failure is not an option; it's the default selection.

Strictly speaking, most use MVVM which is akin to MVPP.

Did you debug? It might help if you indicate the faulty line.
(PS: edit your post to highlight the line instead of replying to me. Smile | :)

[EDIT]Please also put your code between code tags. (select code and press the code button)[/EDIT]

I think the problem resides where you check the !Page.IsPostBack. When you press a button that runs on the server, the page will go into the Page_Load first and then in the event handler of the button. The state is NOT saved between postbacks so this means that the datatables do not exist yet.

You could or recreate the table on each postback or save the information in a session object and take it out. Like this:

if(!Page.IsPostBack){
//create table here
//in the end put in Session object.
}
else{
//Reassign your table with the information from the Session object.
}

You might want to read up on the Asp.Net Page Life Cycle (see google). That will clarify things.

hope this helps.

Hi,
When you are calling the page for first time, the DataTable schema are getting initialized.
When you click on button, you are skipping the datatable initialization by putting it into
condition called !Page.IsPostBack. Better you keep the initialized table object in session and during post back access it from session object.
