System.Web.UI.WebControls.WebParts

Assembly:

System.Web.dll

Performs tasks that must be done prior to rendering CatalogPart controls.

 virtual void PerformPreRender();

public virtual void PerformPreRender ();

abstract member PerformPreRender : unit -> unit
override this.PerformPreRender : unit -> unit

Public Overridable Sub PerformPreRender ()

Examples

The following code example demonstrates how to override the PerformPreRender method to change the background color of the catalog zone. For the full code required to run the example, including the Web page to host these controls, see the Example section of the CatalogPartChrome class overview.

public override void PerformPreRender()
{
    Style zoneStyle = new Style();
    zoneStyle.BackColor = Color.Cornsilk;

    Zone.Page.Header.StyleSheet.RegisterStyle(zoneStyle, null);
    Zone.MergeStyle(zoneStyle);
}

Public Overrides Sub PerformPreRender()
    Dim zoneStyle As Style = New Style
    zoneStyle.BackColor = Drawing.Color.Cornsilk

    Zone.Page.Header.StyleSheet.RegisterStyle(zoneStyle, Nothing)
    Zone.MergeStyle(zoneStyle)
End Sub

Remarks

The PerformPreRender method allows you to perform tasks that must be done during PreRender and cannot be done when the control is rendered, such as applying a style sheet to a control.
