CatalogPartChrome.RenderPartContents Method (HtmlTextWriter, CatalogPart)

 

Renders the main content area of a CatalogPart control, excluding the header and footer.

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

protected virtual void RenderPartContents(
	HtmlTextWriter writer,
	CatalogPart catalogPart
)

Parameters

writer
Type: System.Web.UI.HtmlTextWriter

The HtmlTextWriter that receives the catalogPart content.

catalogPart
Type: System.Web.UI.WebControls.WebParts.CatalogPart

The control currently being rendered.

Exception Condition

The RenderPartContents method enables you to override the rendering of the body area of catalogPart, while leaving rendering of the header and footer to the default rendering.

Notes to Implementers:

You can optionally override the RenderPartContents method. If so, you can simply perform whatever rendering customizations you want for catalogPart, and then call its RenderControl method.

The following code example demonstrates how to override the RenderPartContents method to add text to the catalog part. 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.

protected override void  RenderPartContents(HtmlTextWriter writer, CatalogPart catalogPart)
{
    writer.AddStyleAttribute("color", "red");
    writer.RenderBeginTag("p");
    writer.Write("Apply all changes");
    writer.RenderEndTag();
    catalogPart.RenderControl(writer);
}
