want to clear the cartlist in asp.net ?..

Question

Hi all ,

 

I want to clear the carlist , which I loaded from the order page. Those values to be generated from temporary datatable. I have confirmed it in Cofirm.aspx Page, I have created Session for that tempory table.

 

After saving the Cartlist. I have clear that Session.

 

I share my code ..Anybody know it ., Suggest me to do so .

protected void Page_Load(object sender, EventArgs e)
{
DishCart_DataTable = new DataTable();
DishCart_DataTable.Columns.Add("DishId");
DishCart_DataTable.Columns.Add("ImagePath");
DishCart_DataTable.Columns.Add("DishName");
DishCart_DataTable.Columns.Add("Price");
DishCart_DataTable.Columns.Add("Count");
DishCart_DataTable.Columns.Add("Total");
DishCart_DataTable = (DataTable)Session["DishCart"];
grdCart.DataSource = DishCart_DataTable;
grdCart.DataBind();
if (!IsPostBack)
{
LoadNum();
}

This how I load the Grid ., Now i need it to be clear after saving it to database. How can I null session of datatable values.
