BaseDataList.EnsureDataBound Method

Verifies that the data listing control requires data binding and that a valid data source control is specified before calling the DataBind method.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

protected void EnsureDataBound()

When you specify a value for the DataSourceID property, ASP.NET automatically binds the data listing control to the specified data source control. When ASP.NET performs data binding for the control, it calls the EnsureDataBound method first to verify that the control has not already been bound to data and that a valid data source control that implements the IDataSource interface is specified for its DataSourceID property. The EnsureDataBound method then calls the DataBind method.
