ControlDesigner::CreateErrorDesignTimeHtml Method (String^, Exception^)

 

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

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

protected:
String^ CreateErrorDesignTimeHtml(
	String^ errorMessage,
	Exception^ e
)

Parameters

errorMessage
Type: System::String^

The error message to include in the generated HTML string.

e
Type: System::Exception^

The exception to include in the generated HTML string.

Return Value

Type: System::String^

HTML markup that contains the specified errorMessage and e.

Use the CreateErrorDesignTimeHtml method to provide simple HTML markup that can be used to display error and exception details 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 ControlDesignerobject.

  • The second row contains the input error message and the Message string of the exception.

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

Notes to Inheritors:

The CreateErrorDesignTimeHtml method should be called from the GetViewRendering or GetErrorDesignTimeHtml method when exceptions occur.
