hi how i can filter a datatable with linq to datatable? I have a DropDownList and there I can select the value of the Modul Column. Now I want to filter the DataTable with
You are better of using DataTable.Select method, but if you have to use LINQ then you can try:
DataTable selectedTable = tb.AsEnumerable()
.Where(r => r.Field("Modul") == value)
.CopyToDataTable();
This would create a new DataTable based on filtered values.
If you use DataTable.Select
string expression = "Modul =" + value;
DataRow[] selectedRows = tb.Select(expression);
