Introduction
If you want to develop commerce server application, do remember setup vs.net first, then setup commerce server. After setup, you will find "Commerce Project" option in the New Project list.
The code below will give you a rough idea how to interact with commerce server.
1. Get categories from a Catalog
private void CategoryBind()
{
ProductCatalog ProdCtlg =CommerceContext.Current.CatalogSystem.GetCatalog("LevisJeans");
DataSet ds=
new DataSet();
ds=ProdCtlg.GetRootCategories();
drpCategory.DataSource=ds.Tables[0].DefaultView;
drpCategory.DataTextField="CategoryName";
drpCategory.DataValueField="OrigCategoryName";
drpCategory.DataBind();
}
2. Bind products based on the category selected
private
void DataBind()
{
ProductCatalog ProdCtlg =CommerceContext.Current.CatalogSystem.GetCatalog("LevisJeans");
Category Cg;
Cg=ProdCtlg.GetCategory(drpCategory.SelectedValue);
DataGrid4.DataSource=Cg.GetProducts();
DataGrid4.DataBind();
}

The below get list of products put into cart
private
void DataBind()
{
TransactionContext txContext=TransactionContext.Current;
#if
DEBUG
System.Console.WriteLine("HERE");
#endif
tot_qty=0;
tot_price=0;
DataGrid1.DataSource=txContext.CartOrderForm.LineItems;
DataGrid1.DataBind();
lblTot_Qty.Text=Convert.ToString(tot_qty);
lblTot_Price.Text=Convert.ToString(tot_price);
}
<img src="/KB/aspnet/slcs/cart.jpg">
Below code is to delete one item
int
d=Convert.ToInt16(deleted[j]);
txContext.CartOrderForm.LineItems.Remove(d)
