    Hi,

    You can declare a static variable and store the data in it.

    For example.

    public class StaticVariables
    {
    public static DataTable dt=null;

    }

    and in your method that you pull data from db you can use the code below.

    if(StaticVariables.dt==null)
    {
    //select the data from db and assign it to StaticVariables.dt;
    }
    return StaticVariables.dt;

    So everytime you call method if the variable is null data will be pulled from db. If it is not null data will be returned directly.

    And also if you want to invalidate data just setting the StaticVariables.dt=null will be enough.
