The ASPxHtmlEditor allows users to add placeholders to editor content. The placeholders can then get the required values.


Use the ASPxHtmlEditor.Placeholders property to access a collection of placeholders.

<dx:ASPxHtmlEditor ID="HtmlEditor" runat="server">            
          <dx:HtmlEditorPlaceholderItem Value="FirstName" />
          <dx:HtmlEditorPlaceholderItem Value="LastName" />
          <dx:HtmlEditorPlaceholderItem Value="Title" />
          <dx:HtmlEditorPlaceholderItem Value="BirthDate" />

Users can type a placeholder in the text or use the Insert Placeholder dialog, which allows users to insert and change placeholders.

To replace placeholders with the required values, use the client-side ASPxClientHtmlEditor.ReplacePlaceholders or server-side ASPxHtmlEditor.ReplacePlaceholders method.
