How to: Implement a popup window from which users can select templates
- 5 minutes to read
In this example, a user opens the popup window to select a template from the predefined list of text templates. ASPxHtmlEditor inserts the selected template at the beginning of its text. The example uses the client-side GetSelectedItems method to get the selected item’s text.
