The DevExpress ASP.NET HTML Editor (ASPxHtmlEditor) can process HTML content copied/pasted from another application (for example, Microsoft Word). Use the following settings to format the pasted content: AllowSaveBinaryImageToServer - Specifies whether a pasted image is saved to the server and its generated URL used in HTML, or if it is processed as a base64 image. ProcessRtfContentPastingOnServer - Specifies whether to process the copied/cut RTF content on the server side. Using the RtfContentPastingProcessed event allows processing the HTML obtained from the copied/cut RTF before pasting it to the ASPxHtmlEditor. StyleAttributeFilterMode - Specifies the filtering mode for the Html Editor's style attributes defined by the StyleAttributes property. StyleAttributes - Specifies the list of allowed/unallowed style attributes depending on the filtering mode defined by the StyleAttributeFilterMode property. In this demo, use the options on the right to see how these options affect the pasted content.
