This tutorial is a basic introduction of how to write a simple data driven application using Visual Studio 2008 wizards without writing a single line of code.In my next articles, I will talk about more detailed features of the Data Grid View control.Binding data to the Data Grid View control is straightforward and intuitive, and in many cases it is as simple as setting the Data Source property. When you bind to a data source that contains multiple lists or tables, set the Data Member property to a string that specifies the list or table to bind to. This scenario can be achieved by using the Row Validating event, which is fired when the user tries to change the current row (changing to another row or when the control loses focus).Note that only the Cell Validating event can keep the editor active,when the validation fails and it does not allow the user to exit the cell until a valid value is filled.This control also let's you display data in a master-details view. With the Data Grid View control, you can display and edit tabular data from many different kinds of data sources. Now your data source is created, right click on Data Grid View control and on the option Choose Data Source, select the data source you just created.

Displaying a Combo Box in Cell Frequently, besides displaying text in a cell you may want to display a drop-down list box to allow users to select from a list of pre-determined values.

The Data Bound Item will be updated only if the cell is validated.

However, the user may prefer to validate all the data cells in a row at once.

The Data Grid View control supports the standard Windows Forms data binding model, so it will bind to instances of classes described in the following list: The Data Grid View control supports data binding to the public properties of the objects returned by these interfaces or to the properties collection returned by an ICustom Type Descriptor interface, if implemented on the returned objects.

provides a convenient way to realize data validation before it is committed to the underlying data source. Add("Price", "Price") '---create a new bindingsource control--- Dim bindingsource As New Binding Source '---add the items into the control--- bindingsource. Header Text = "Types" '---data bind it--- combo Box Col. Add("Type C") '---create a combobox column--- Dim combo Box Col As New Data Grid View Combo Box Column '---set the header--- combo Box Col. While this code snippet may solve the question, including an explanation really helps to improve the quality of your post.
