Datagrid rowupdating event
I am loading data from an sql database into a grid.
By default when the Grid View controls goes in edit mode, it displays Text Boxes for entering values.
You can not attach validation controls directly to these Text Boxes.
A powerful sequence of Mantra, Pranayama, Hand Mudras and Meditation. There can be several approaches taken for validating data. For our example we are going to use Customers table of Northwind database. Open its smart tag and choose "Configure Data Source" option to start Configure Data Source wizard.
On the first step of the wizard click on "New Connection" button to open a dialog as shown in Figure 1.
