Hi everyone! I haven't seen this question here, so I'll give it a try.

I'm from a country where some words have accents, like MarĂ­a.

I have all this words in a database and I would like to use the Select function from a DataTable but ignoring accents in the database.

I know this may be not possible; if it's not, it really should be implemented. Thanks in advance!
This is my current code:

dataTable.DefaultView.RowFilter = string.IsNullOrEmpty(text) ? string.Empty : string.Format("{0} LIKE '%{1}%'", field, text);

I believe you are going to have to normalize and strip the diacritics from the string first.

see: http://stackoverflow.com/questions/249087/how-do-i-remove-diacritics-accents-from-a-string-in-net

You could add new column to your datatable with the processed string and then do the row filter against that processed string.

Or you could use LINQ to create a list of datarows and use that presumably as a datagridview.DataSource.

Something like this:

List<DataRow> rows = (from row in dt.AsEnumerable() 
                      where System.Text.RegularExpressions.Regex.IsMatch(RemoveDiacritics(((DataRow) row)[0].ToString()), "Maria*") 
                      select row).ToList();
