Render Method

Control.Render Method (HtmlTextWriter)

 

Sends server control content to a provided HtmlTextWriter object, which writes the content to be rendered on the client.

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

Protected Friend Overridable Sub Render (
	writer As HtmlTextWriter
)

Parameters

writer
Type: System.Web.UI.HtmlTextWriter

The HtmlTextWriter object that receives the server control content.

When developing custom server controls, you can override this method to generate content for an ASP.NET page.

The following code example demonstrates overriding the Render method. The HasControls method is used to determine whether the server control has any child controls stored in its ControlCollection object, which is accessible through the Control.Controls property. If HasControls returns true and the first server control in the collection is literal text, then the literal text is appended to an HTML string.

<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> _
Protected Overrides Sub Render(Output As HtmlTextWriter)
    If HasControls() And TypeOf Controls(0) Is LiteralControl
        Dim Ctrl As LiteralControl = CType(Controls(0), LiteralControl)
        Output.Write("<H2>Your Message: " & Ctrl.Text & "</H2>")
    End If
End Sub
