How to: Change the Mail Merge data sources at runtime

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T542064.

This example illustrates how to switch data sources used for Mail Merge in ASPxRichEdit at runtime.

To update ASPxRichEdit's data source dynamically, wrap it in the ASPxCallbackPanel control and use its callbacks to refresh data.
Note that ASPxRichEdit should be bound to actual data on every round-trip to the server, so it is insufficient to set the data source in the server-side Callback event handler only. It's necessary to restore the actual data source and bind ASPxRichEdit to it on each request in the Page_Init event handler.
In addition, it is necessary to clear the current document in ASPxRichEdit each time the data source is changed. For this purpose, you can use the server-side ASPxRichEdit.New method.
