'Declaration Public Property TitlebarImageName As String
public string TitlebarImageName {get; set;}
This property supplies an image name which is used as a dialog "icon" in the upper left corner of the dialog. This property is only used when the HtmlBoxDialog.Type property = DialogType.InternalWindowWithTitlebar.
This property will come preset to a valid imagename found in the images directory (specified by WebHtmlEditor.ImageDirectory) created during the product installation. Set this property only if you wish to change from the presets.
WebHtmlEditor automatically assumes that all images are in the directory specified by WebHtmlEditor.ImageDirectory. For example, if the value of WebHtmlEditor.ImageDirectory is "/ig_common/images/htmleditor/" (the default) and this property was set to "myimage.jpg", the control would assume the file can be found at "/ig_common/images/htmleditor/myimage.jpg". If you set this property to a string that has some form of directory designation, such as "slashes" within it (for example "C:\temp\myimage.jpg") the control would no longer assume that the image is within WebHtmlEditor.ImageDirectory but would use the full path you supplied for this property.
