Binds a data source to the invoked server control and all its child controls.
Assembly: System.Web (in System.Web.dll)
Use this method to bind data from a source to a server control. This method is commonly used after retrieving a dataset through a database query. Most controls perform data binding automatically, which means that you typically do not need to call this method explicitly.
This method is commonly overridden when you create a custom templated data-bound control. For more information, see How to: Create Templated ASP.NET User Controls and Developing Custom Data-Bound Web Server Controls. When called on a server control, this method resolves all data-binding expressions in the server control and in any of its child controls.
The following example overrides the DataBind method in a custom ASP.NET server control. It begins by calling the base OnDataBinding method and then uses the ControlCollection::Clear method to delete all the child controls and the ClearChildViewState method to delete any saved view-state settings for those child controls. Finally, the ChildControlsCreated property is set to true and the control is instructed to track any changes to the view state of the newly created controls with the TrackViewState method. This is a common technique when binding data to a control to ensure that new data does not conflict with data stored from a previous DataBind method call.
