C# with Entity, Send Data from Parent Form to Child Form

In Child Form Create an entity object as public and set all form field with that entity property. Like This code:

1 2 3 4 5 6 7 8 9 10 11 12 13

//Declare Purchase Entity Object as Public public PurchaseInfo _purchaseInfoObj = new PurchaseInfo(); //Load Purchase Data from Parent Window to Child Form public void LoadDataFromDueList() { txtProductID.Text = this._purchaseInfoObj.ProductId.ToString(); txtProductName.Text = this._purchaseInfoObj.ProductName; txtSupplierName.Text = this._purchaseInfoObj.SupplierName; txtTotalPurchaseAmount.Text = this._purchaseInfoObj.TotalPurchaseAmount.ToString(); txtTotalDue.Text = this._purchaseInfoObj.TotalDue.ToString(); }

Now in Parent Form, create an Event and write code like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

//Collect Data from Listview and Send it to child form private void MakePaymentContexMenu_Click(object sender, RoutedEventArgs e) { if (PurchaseDueListView.SelectedIndex > -1) { SupplierDueCollectionUI supplierDueCollectionUI = new SupplierDueCollectionUI(); PurchaseInfo purchaseObj = new PurchaseInfo(); purchaseObj = PurchaseDueListView.SelectedItem as PurchaseInfo; // select and load data from listview supplierDueCollectionUI._purchaseInfoObj = purchaseObj; // send it to public entity _purchaseInfoObj supplierDueCollectionUI.LoadDataFromDueList(); // Call data load method from child form supplierDueCollectionUI.ShowDialog(); // show child form } }
