I come across many situations when I have multiple sort conditions, based on an enum, and I wanted a dynamic way of doing it without having to write a case statement to deal with it.
This, only works if your properties match up with the enum values, but that is usually the case I find.
Here is the Enum:
public enum SortBy
{
Option1 = 1,
Option2 = 2,
Option3 = 3
}
Here is the Custom Class
private class CustomGrid
{
public string Option1 { get; set; }
public string Option2 { get; set; }
public string Option3 { get; set; }
}
Here is the sort Code:
private IQueryable SortDate(IQueryable Data)
{
bool IsDesc = Convert.ToBoolean(Convert.ToInt32(ddlSortDir.SelectedValue));
var propertyInfo = typeof(CustomGrid).GetProperty(ddlSortBy.SelectedItem.Value).Name;
Data = Data.OrderByWithDirection(o => propertyInfo, isDescending);
return pData;
}
