Question

I’m writing my own gridview control. The problem is sorting. What is best practic to do that.

I can write function like that:

public object GetDataForGrid(int currentPage, int rowsPerPage, string sortColumnName, string sortDirection)
{

        if(sortColumnName="Date" && sortDirection=="ASC")
    {
       return Detalizations.OrderBy(x => x.Date).Skip(currentPage*rowsPerPage).ToList();
    }           

        .....
        //And over 9000 other branches
}

But ofcourse these solution is not optimal and looks oververbose. But how i can do it right?

Maybe reflection could help me?

Answer 1

what don’t you use the GridView.Sort Method which is made for that scope

have also a look at:
