Provides data for the ContextCreating event.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
By default, the LinqDataSource control creates an instance of the type that is specified in the ContextTypeName property. The LinqDataSource control calls the default constructor of the data context object to create an instance of the object.
You can manually create the data context object by handling the ContextCreating event. You do this if you want to use a non-default constructor.
You can also handle the ContextCreating event if you want to create a data context object that is different from the one specified in the ContextTypeName property. In that case, you set the ObjectInstance property to the object you created. The LinqDataSource control will use the object you have created for selecting the data. When you are updating, inserting, or deleting data, you must set the ObjectInstance property to an object that derives from the DataContext class.
The following example shows how to create the data context object by calling a non-default constructor in an event handler for the ContextCreating event. The code assigns the custom object to the ObjectInstance property.
