Download free day trial. This article describes how to customize the RadGridView columns by using predefined column types and how to extend the functionality of the columns by defining a non-default editor. When you use a standard GridViewDataColumn , the RadGridView control automatically generates controls for the cell's view and edit modes:. TextBlock : For string , numeric and DateTime properties. Sometimes you need to extend the functionality of a column and define a custom editor.

Example 1 demonstrates how to use both properties to customize your columns. When you define a CellEditTemplate for a column, the default validation mechanism is bypassed as you're directly binding to the source property. If you require this validation, create a custom column editor instead. It is also used when inserting a new item. You can data bind components in the editor template to the current context, which is an instance of the model the grid is bound to.

You will need a global variable that is also an instance of the model to store those changes. The template receives a copy of the original model, so that changes can be cancelled with the Cancel command. See the Notes section of the Editing Overview article for more details on how and when that copy is created. If you need to perform logic more complex than simple data binding, use the change event of the custom editor component to perform it. You can also consider using a custom edit form.
