HtmlTextWriter Constructors

Definition

Namespace:

System.Web.UI

Assembly:

System.Web.dll

Initializes a new instance of the HtmlTextWriter class.

Overloads

HtmlTextWriter(TextWriter)	Initializes a new instance of the HtmlTextWriter class that uses a default tab string.
HtmlTextWriter(TextWriter, String)	Initializes a new instance of the HtmlTextWriter class with a specified tab string character.

HtmlTextWriter(TextWriter)

Initializes a new instance of the HtmlTextWriter class that uses a default tab string.

C#

public HtmlTextWriter(System.IO.TextWriter writer);

Parameters

writer

TextWriter

The TextWriter instance that renders the markup content.

Examples

The following code example demonstrates how to use the HtmlTextWriter(TextWriter) constructor to create a custom HtmlTextWriter object named StyledLabelHtmlWriter. When the MyPage custom class, which is derived from the Page class, is requested by a client browser, it uses the StyledLabelHtmlWriter class to render its content to the output stream.

C#

// A custom class that overrides its CreateHtmlTextWriter method.
// This page uses the HtmlStyledLabelWriter class to render its content.
[AspNetHostingPermission(SecurityAction.Demand,
    Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(SecurityAction.InheritanceDemand,
    Level = AspNetHostingPermissionLevel.Minimal)]
public class MyPage : Page
{
    protected override HtmlTextWriter CreateHtmlTextWriter(TextWriter writer)
    {
        return new HtmlStyledLabelWriter(writer);
    }
}

Remarks

The HtmlTextWriter overload of the HtmlTextWriter(TextWriter) constructor uses the DefaultTabString constant when indentation of a line is necessary. It calls the HtmlTextWriter(TextWriter, String) overload to initialize the new instance.

HtmlTextWriter(TextWriter, String)

The string to use to render a line indentation.

Examples

The following code example demonstrates how to use the HtmlTextWriter(TextWriter) constructor to create a custom HtmlTextWriter object named StyledLabelHtmlWriter. When the MyPage custom class, which is derived from the Page class, is requested by a client browser, it uses the StyledLabelHtmlWriter class to render its content to the output stream.

C#

// A custom class that overrides its CreateHtmlTextWriter method.
// This page uses the HtmlStyledLabelWriter class to render its content.
[AspNetHostingPermission(SecurityAction.Demand,
    Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(SecurityAction.InheritanceDemand,
    Level = AspNetHostingPermissionLevel.Minimal)]
public class MyPage : Page
{
    protected override HtmlTextWriter CreateHtmlTextWriter(TextWriter writer)
    {
        return new HtmlStyledLabelWriter(writer);
    }
}

Remarks

The HtmlTextWriter overload of the HtmlTextWriter(TextWriter, String) constructor uses tabString when indentation of a line is necessary. It calls the TextWriter.TextWriter(IFormatProvider) base constructor to initialize the new instance.
