Add(year Column); Binding List You need to implement the INotify Property Changed interface on the object that is storing the data. I encourage you to still read this article to get an overview of the rationale behind the custom Grid View control and to understand the initial architecture. NET 2.0, the Grid View control serves as a much more functional and feature-rich choice.A column of radio buttons is a suitable user interface when the user is limited to choosing at most one item from the grid.At times, however, we may want to allow the user to pick an arbitrary number of items from the grid.Keep in mind that the entire process is kicked off by the user clicking a Link Button in one of the sortable column's headers, and completes by displaying the data in the requested sorted order.In the preceding tutorial we examined how to add a column of radio buttons to the Grid View for the purpose of selecting a particular record.Auto Generate Columns = false; Data Grid View Text Box Column make Column = new Data Grid View Text Box Column(); make Column. Header Text = "The Car's Make"; Data Grid View Text Box Column model Column = new Data Grid View Text Box Column(); model Column.

The Check Box Field, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the Image Field renders an image whose image source is based upon a specified data field.

Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the Hyper Link Field and Button Field field types.

The simplest field type is the Bound Field, which displays a data value as text.

Other field types display the data using alternate HTML elements.
