Gets or sets a value that specifies whether to process the copied/cut RTF content on the server side.

Namespace: DevExpress.Web.ASPxHtmlEditor

Assembly: DevExpress.Web.ASPxHtmlEditor.v24.2.dll

Declaration

C#

[DefaultValue(true)]
public bool ProcessRtfContentPastingOnServer { get; set; }

VB.NET

<DefaultValue(True)>
Public Property ProcessRtfContentPastingOnServer As Boolean

Property Value

Type	Default	Description
Boolean	true	true, to process the copied/cut RTF content on the server side; otherwise, false.

Remarks

To paste the RTF content from a clipboard with the original formatting, set the ProcessRtfContentPastingOnServer property to true. It enables converting the RTF content to HTML on the server and then paste it to the editor.

ASPX

<dx:ASPxHtmlEditor runat="server">
    <SettingsHtmlEditing ProcessRtfContentPastingOnServer="true"></SettingsHtmlEditing>
</dx:ASPxHtmlEditor>

The time the RTF content is processed on the server, a loading panel with the temporary HTML content is shown in the editor. The following example illustrates how to obtain the temporary HTML.

JS

function onBeforePaste(s, e) {
  if(e.html.indexOf('id="dx-tmpRtf') > -1)
      alert("The temporary content will be pasted.");    
  else
      alert("Default behavior.");
}

ASPX

<dx:ASPxHtmlEditor ID="ASPxHtmlEditor1" runat="server">
    <ClientSideEvents BeforePaste="onBeforePaste" />
    <SettingsHtmlEditing ProcessRtfContentPastingOnServer="true"></SettingsHtmlEditing>
</dx:ASPxHtmlEditor>

Settings for images from the RTF content are specified by the HtmlEditorDefaultDialogSettings.InsertImageDialog property (provided that the ASPxHtmlEditorSettings.AllowSaveBinaryImageToServer property is set to true).

ASPX

<SettingsDialogs>
    <InsertImageDialog>
        <SettingsImageUpload UploadStorage="...">
        </SettingsImageUpload>
    </InsertImageDialog>
</SettingsDialogs>

Note that with the enabled ProcessRtfContentPastingOnServer property, the ASPxClientHtmlEditor.BeforePaste and ASPxClientHtmlEditor.HtmlChanged client events are raised both before and after the content processing.

Known Limitations

• Microsoft Edge does not provide access to the RTF content in clipboard.
• The ProcessRtfContentPastingOnServer property is not in effect if the ASPxHtmlEditorHtmlEditingSettings.PasteMode property is set to HtmlEditorPasteMode.PlainText and the ASPxHtmlEditorHtmlEditingSettings.EnablePasteOptions is disabled.
• The ProcessRtfContentPastingOnServer property is not in effect if the copied/cut content doesn’t contain raw text/rtf data.
