Placeholders

• Jul 13, 2021

The ASPxHtmlEditor allows end-users to add placeholders to editor content. The placeholders can then be replaced with the required values.

The collection of placeholders available for end-users is accessed by the ASPxHtmlEditor.Placeholders property.

ASPX

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

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

The dialog can be invoked in the following ways.

• By clicking the Insert Placeholder toolbar button (ToolbarInsertPlaceholderDialogButton).
• By clicking the Change Placeholder… command in the context menu.
• By double clicking a placeholder.
• By calling the ASPxClientHtmlEditor.ExecuteCommand method with the INSERTPLACEHOLDER_DIALOG_COMMAND or CHANGEPLACEHOLDER_DIALOG_COMMAND parameter.

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