System.Web.UI.WebControls.BaseDataList.EnsureDataBound Method

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

Syntax

protected void EnsureDataBound ()

Remarks

When you specify a value for the BaseDataList.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 BaseDataList.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 System.Web.UI.IDataSource interface is specified for its BaseDataList.DataSourceID property. The BaseDataList.EnsureDataBound method then calls the BaseDataList.DataBind method.
