String^ CreateErrorDesignTimeHtml(

member CreateErrorDesignTimeHtml :

The error message to include in the generated HTML string.


The exception to include in the generated HTML string.

Return Value


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 property of the ControlDesignerobject.

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

To generate HTML markup for an error message without specifying an exception, use the CreateErrorDesignTimeHtml 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.
