ControlDesigner::CreateErrorDesignTimeHtml Method (String^)

 

Creates HTML markup to display a specified error message at design time.

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

protected:
String^ CreateErrorDesignTimeHtml(
	String^ errorMessage
)

Parameters

errorMessage
Type: System::String^

The error message to include in the generated HTML markup.

Return Value

Type: System::String^

An HTML markup string that contains the specified error message.

Use the CreateErrorDesignTimeHtml method to create HTML markup to display an error message for a control at design time. The value for errorMessage specifies a localized string that is displayed to the user of the control at design time.

The ControlDesigner class implementation of the CreateErrorDesignTimeHtml method returns a table with two rows, as follows:

  • The first row contains the type name and site name for the Component property of the ControlDesigner object.

  • The second row contains the input error message string.

To generate HTML markup for an error message with an associated exception, use the CreateErrorDesignTimeHtml(String^, Exception^) overload. To generate HTML markup for an exception without specifying a localized error message, use the GetErrorDesignTimeHtml method.

Notes to Inheritors:

The CreateErrorDesignTimeHtml(String^) overload is functionally equivalent to calling the CreateErrorDesignTimeHtml(String^, Exception^) method with e set to null.
