protected:
 System::String ^ CreatePlaceHolderDesignTimeHtml();
protected string CreatePlaceHolderDesignTimeHtml ();
member this.CreatePlaceHolderDesignTimeHtml : unit -> string
Protected Function CreatePlaceHolderDesignTimeHtml () As String

Returns

A string that contains design-time HTML markup providing basic information about the control.

Notes to Inheritors

The typical design pattern is to try to get HTML markup through the associated control, and then if an error is encountered, call the GetErrorDesignTimeHtml(Exception) method. If no markup is returned by the control, call the GetEmptyDesignTimeHtml() method, which if it is not overridden to provide specific markup, calls the CreatePlaceHolderDesignTimeHtml() method, which should contain information about the type and ID of the control.

Examples

The following code example demonstrates how to override the GetDesignTimeHtml method in a templated control designer. A string is then passed as the instruction parameter in a call to the CreatePlaceHolderDesignTimeHtml method, which provides the design-time HTML markup.

This code example is part of a larger example provided for the TemplateGroups property.

// Add instructions to the placeholder view of the control
public override string GetDesignTimeHtml()
{
    return CreatePlaceHolderDesignTimeHtml("Click here and use " +
        "the task menu to edit the templates.");
}
' Add instructions to the placeholder view of the control
Public Overloads Overrides Function GetDesignTimeHtml() As String
    Return CreatePlaceHolderDesignTimeHtml("Click here and use " & _
        "the task menu to edit the templates.")
End Function
