Hi, :)

I use a radgridview inside my application where certain words inside of cells should be marked. At the moment I solved this via DisableHTMLRendering and manipulating the data displayed in the cells... for instance with

cellInfo.Value = "<html>" + cellInfo.Value.ToString() + "</html>";

foreach (KeyValuePair<String, Color> kvp in this._highlightWords)

{

cellInfo.Value = Regex.Replace(cellInfo.Value.ToString(), kvp.Key, "<span style=" + '"' + "background-color:" + System.Drawing.ColorTranslator.ToHtml(kvp.Value) + '"' + ">" + kvp.Key + "</span>", RegexOptions.IgnoreCase);

string[] tmpString = Regex.Split(cellInfo.Value.ToString(), kvp.Key, RegexOptions.IgnoreCase);

}

I have a list of words to be marked and I want them to have a colored background... depending on the current word.

Works fine so far, but I do have problems with the encoding. Special characters, like "ä", "ö" are not displayed properly... is there any way to set the encoding?

I already tried to hard-convert my content to utf-8, but that didn't change anything.

byte[] utf8String = Encoding.UTF8.GetBytes(cellInfo.Value.ToString());

cellInfo.Value = Encoding.UTF8.GetString(utf8String);

The data is received from a SQLCE database... am I doing something wrong? Or is this only solvable via the webbrowsercolumns you mentioned in another thread? Will those webbrowsercolumns still be performant, if I do have thousands of them? :)

Thanks in advance!
Kind Regards
Fabian

Hello Fabian,

Thank you for your question.

I would like to clarify that the Html-like and non Html-like text drawing uses a same method to draw strings - the GDI+ Graphics DrawString method which properly render such characters - so you should be able to display characters like "ä", "ö" in the both cases. Far as I know, the umlauts displayed directly in the font - so set the Grid Font property to the font "Arial Unicode MS" - if this does not help try to encode the value that comes from the database not the string from the cell Value - please, refer to this MSDN forum.

I hope this helps.
