I m expecting  as Rohit Vats mentioned in his Comment too  that you have a wrong structure in your DataTable  Try something like this    var t   new DataTable          create column header   foreach   string s in identifiders         t Columns Add new DataColumn s        lt  lt     i m expecting you don t have defined any DataColumns  haven t you            Add data to DataTable   for   int lineNumber   identifierLineNumber  lineNumber  lt  lineCount  lineNumber           DataRow newRow   t NewRow        for   int column   0  column  lt  identifierCount  column             newRow column    fileContent ElementAt lineNumber  column             t Rows Add newRow          return t DefaultView   I have used this DataTable in a ValueConverter and it works like a charm with the following binding  xaml    lt DataGrid AutoGenerateColumns  quot True quot  ItemsSource  quot  Binding Path FileContent  Converter  StaticResource dataGridConverter   quot    gt   So what it does  the ValueConverter transforms my bounded data  what ever it is  in my case it s a List lt string   gt   into a DataTable  as the code above shows  and passes this DataTable to the DataGrid  With specified data columns the data grid can generate the needed columns and visualize them  To say it in a nutshell  in my case the binding to a DataTable works like a charm

I d do it this way   grid1 DataContext   dt AsEnumerable   Where x   gt  x  lt  10  AsEnumerable   CopyToDataTable   AsDataView      and do whatever query i want between the two AsEnumerable    If you don t need space for query  you can just do directly this   grid1 DataContext   dt AsDataView
