Jan 29, 2008 - to my LINQ query below, though intellisense doesn't even give that option! My DataSet has multiple tables, all populated with data. SELECT multiple columns from DataTable using LINQ in C# and VB.Net. If the selected value is not empty, then DataTable records are filtered using the WHERE clause of LINQ and the results are used to populate the GridView control. If the selected value is empty, then simply the DataTable is used to populate the GridView control.
My datatable like Company Name Department A Raja Mechanical B Mano Electrical A Mohan Computer B Rajesh Computer C Siva Robotics D Jeeva Computer C Prakash Electrical A Vinoth Mechanical I want to group like below Company Name Department A Raja Mechanical A Mohan Computer A Vinoth Mechanical B Mano Electrical B Rajesh Computer C Siva Robotics C Prakash Electrical D Jeeva Computer Company Name have to group like this.
