HierarchicalDataBoundControlAdapter.PerformDataBinding Method

Definition

Binds the data in the data source of the associated hierarchical data-bound control to the adapter.

protected public:
 virtual void PerformDataBinding();
protected internal virtual void PerformDataBinding ();
abstract member PerformDataBinding : unit -> unit
override this.PerformDataBinding : unit -> unit
Protected Friend Overridable Sub PerformDataBinding ()

Examples

The following code example demonstrates how to override the PerformDataBinding method to verify the DataSourceID property has been set prior to calling the parent PerformDataBinding method. This code example is part of a larger example provided for the HierarchicalDataBoundControlAdapter class.

protected new System.Web.UI.WebControls.TreeView Control
{
    get
    {
        return (System.Web.UI.WebControls.TreeView)base.Control;
    }
}
Protected Overloads ReadOnly Property Control() As _
    System.Web.UI.WebControls.TreeView

    Get
        Return CType( _
            MyBase.Control, _
            System.Web.UI.WebControls.TreeView)
    End Get
End Property

Remarks

The PerformDataBinding method binds the data in the specified data source of the associated HierarchicalDataBoundControl control to the HierarchicalDataBoundControlAdapter object. You can override PerformDataBinding to replace the standard data-binding functionality of the associated HierarchicalDataBoundControl control or to provide additional data-binding functionality if the associated HierarchicalDataBoundControl control has been extended.
