I have a datatable dt3 with some records. In one of the event I put 2 conditions, if
'currentable'=null and else. When I put the break point and verified , it enters the 'null' area
which it should not as dt3 has records. Because of this, variable 'v_MyCart' becomes zero which
I dont want to happen. My requirement is, since dt3 has records it has to go to the line 'if(dt3.Rows.Count>0' . Any wrong in my approach and code. I hereunder submit my code:

C#

DataTable dt3 = new DataTable();
                    dt3 = (DataTable)Session["ss"];
                    ViewState["CurrenTable"] = dt3;
                    if (ViewState["CurrentTable"]==null)
                    {
                        v_MyCart = 0;

                    }
                    else
                    {

                        if (dt3.Rows.Count > 0)
                        {

C#

DataTable dt3 = new DataTable();
//First check is your session is null or not
if (Session["ss"] != null)
{
    dt3 = (DataTable)Session["ss"];
    ViewState["CurrenTable"] = dt3; //Now you have assigned a viewstate here
    if (((DataTable)ViewState["CurrentTable"]).Rows.Count == 0)
    { //Check assigned table has any rows or not
        v_MyCart = 0;
    }
    else //if (dt3.Rows.Count > 0)
    {//Data exists do something }
}
