Parameters

Returns

A string that contains the markup used to render the associated LoginView at design time after an error has occurred.

Examples

The following code example shows how to override the GetErrorDesignTimeHtml method in a class that is inherited from the LoginViewDesigner class to change the appearance of a control that is derived from the LoginView class at design time. The example generates the markup for a placeholder that includes the error message, which is rendered in red, bold text.

// Generate the design-time markup for the control when an error occurs.
protected override string GetErrorDesignTimeHtml(Exception ex) 
{
    // Write the error message text in red, bold.
    string errorRendering =
        "<span style=\"font-weight:bold; color:Red; \">" +
        ex.Message + "</span>";

    return CreatePlaceHolderDesignTimeHtml(errorRendering);
} // GetErrorDesignTimeHtml

' Generate the design-time markup for the control when an error occurs.
Protected Overrides Function GetErrorDesignTimeHtml( _
    ByVal ex As Exception) As String

    ' Write the error message text in red, bold.
    Dim errorRendering As String = _
        "<span style=""font-weight:bold; color:Red; "">" & _
        ex.Message & "</span>"

    Return CreatePlaceHolderDesignTimeHtml(errorRendering)

End Function ' GetErrorDesignTimeHtml

Remarks

The error design-time LoginView control renders as a panel that contains the type name, the control name, and messages announcing and describing the error.
