The article assumes you are familiar with Web Data Grid component. Select the new field in the Selected Fields list 1.5.1. In the grid’s Properties window, switch to the Events view Approach for the Web Hierarchical Data Grid is generally the same, although configuring for child bands requires you to add settings and apply the logic in scope of a child band. If you are not, consider the starting point at this . Set Data Format String to (your value will vary depending on needs) 1.5.2. Decimal (your value will vary depending on needs) 1.5.3. Like it or not still 2D tables are one of the most comfortable user interface elements in not only viewing data but also in performing rapid inserts and updates. Ajax: Virtual Scrolling Web Data Grid Web Hierarchical Data Grid 1. CRUD operations of Data Grid is not a big innovation, but there are plenty of ways to do that. Row Updated Event Args e) 31: Note In the View Model class Carton View Model Guid property is used as the object identifier in the collection. NET Session) For the new rows we set the Carton Info Id to –1, because this is an identity column in the database. I will demonstrate the setup of each behavior needed in order to make this happen. In ASPX In Code Behind Execute in Initialize Row event handler using Infragistics. I will show how to use Editor Providers with Add New Row feature also. Implement the field’s logic in the Row Initialized event 2.1.
You also learn to batch updates and add simple Ajax interaction to give the page a smooth streamlined feel.
The key to executing these operations on the client is being aware of a few lines of Java Script. Items[index Of Bound2]; decimal unit Price = Convert.
This tutorial demonstrates how to insert, update and delete data in the grid entirely from the client.
Purpose Web Data Grid (WDG) has the capability to update the Data Source automatically if Auto GRUD property of Editing Core is set to true. This is a technique used by developers to persist all changes made in the grid UI to the Data Source by their own custom code. Grid Record Item unbound; Grid Record Item bound1; Grid Record Item bound2; int index Of Unbound = 4; int index Of Bound1 = 3; int index Of Bound2 = 2; unbound = e.
In this article I will go through the steps required to get WDG involved in Manual Crud scenario. Implement the logic for your unbound field in the Row Initialized event handler Creating an Unbound Column The following code implements the logic for a total column which multiplies price by quantity.
