Grid Need Data Source Event Args) Handles Rad Grid1. Grid Source 'Locate the changed row in the Data Source Dim changed Rows As Data Row() = orders Table. Grid Source End Sub Protected Sub Rad Grid1_Update Command(By Val source As Object, By Val e As Telerik. Item, Grid Editable Item) Dim orders Table As Data Table = Me. You must configure the data source so that it supports the automatic operations.You also need to set the Data Key Names property of the table views in the grid so that the insert, update, and delete operations perform as expected.Once it is bound to a Data Source control that supports Insert, Update, and Delete operations, Rad Grid can take an advantage of the data source capabilities to perform the required operations with no code except error handling required.In order to achieve this, you need to set the following three properties: The automatic data source operations only work when binding the grid to a declarative data source using the Data Source ID property of the grid.
