Hi Ramesh,

I am not sure what you are trying to achieve exactly - get the pending transactions on the client or you would like to process the transactions on the server?

On the client, you can get those by:

var hierarchicalGridChildren = $("#hierarchicalGrid").igHierarchicalGrid("allChildren");

var transactions = hierarchicalGridChildren.igGrid("pendingTransactions");

On the server:

        [ActionName("EditingSaveChanges")]
        public ActionResult EditingSaveChanges()
        {
            ViewData["GenerateCompactJSONResponse"] = false;
            GridModel m = new GridModel();
            List<Transaction<Category>> categoryTransactions = m.LoadTransactions<Category>(HttpContext.Request.Form["ig_transactions"]);
            foreach (Transaction<Category> t in categoryTransactions)
            {
                DataRow dr = this.CategoriesProducts.Tables["Categories"].Rows.Find(Int32.Parse(t.rowId));
                if ((t.layoutKey == null) && (dr != null))
                {
                    if (t.type == "row")
                    {
                        Category categoryRow = (Category)t.row;
                        if (categoryRow.CategoryName != null) {
                            dr["CategoryName"] = categoryRow.CategoryName;
                        }
                        if (categoryRow.Description != null){
                            dr["Description"] = categoryRow.Description;
                        }
                    } else if (t.type == "deleterow")
                    {
                        this.CategoriesProducts.Tables["Categories"].Rows.Remove(dr);
                    }
                }
            }
            List<Transaction<Product>> productTransactions = m.LoadTransactions<Product>(HttpContext.Request.Form["ig_transactions"]);
            foreach (Transaction<Product> t in productTransactions)
            {
                DataRow dr = this.CategoriesProducts.Tables["Products"].Rows.Find(Int32.Parse(t.rowId));
                if ((t.layoutKey == "Products") && (dr != null))
                {
                    if (t.type == "deleterow")
                    {
                        this.CategoriesProducts.Tables["Products"].Rows.Remove(dr);
                    }
                    else if (t.type == "row")
                    {
                        Product productRow = (Product)t.row;
                        if (productRow.ProductName != null)
                        {
                            dr["ProductName"] = productRow.ProductName;
                        }
                        if (productRow.CategoryID != null)
                        {
                            dr["CategoryID"] = productRow.CategoryID;
                        }
                        if (productRow.UnitPrice != null)
                        {
                            dr["UnitPrice"] = productRow.UnitPrice;
                        }
                        if (productRow.UnitsInStock != null)
                        {
                            dr["UnitsInStock"] = productRow.UnitsInStock;
                        }
                        dr["Discontinued"] = productRow.Discontinued;
                    }
                }
            }
            JsonResult result = new JsonResult();
            Dictionary<string, bool> response = new Dictionary<string, bool>();
            response.Add("Success", true);
            result.Data = response;
            return result;
        }

Does the above help you?
