Blazor Rich Text Editor — Mail Merge (v22.1)

ASP.NET Team Blog
24 August 2022

As you may know, our most recent major update (v22.1) introduced a new Mail Merge feature within the DevExpress Blazor Rich Text Editor.

Mail Merge automates the creation of many business-specific documents, including catalogs, reports, and external communications. To integrate this feature in your Blazor app, you need to bind a data source to a rich text document with merge fields. Our Rich Text Editor will automatically replace merge fields in the document with information from the bound data source.

To begin, simply assign a data source to the Data property (to bind data to your document template):

<DxRichEdit …>
        <DxMailMergeSettings Data="@DataSource" />
protected override async Task OnInitializedAsync() {
    // …
    DataSource = await CustomDataService.GetCustomDataAsync();
    await base.OnInitializedAsync();

Add { MERGEFIELD "field name" } fields to you document to create a document template. Our Blazor Rich Text Editor's UI allows you to insert merge fields based on the bound data source, preview merged data, and “navigate” through data records.

Mail Merge UI

The Rich Text Editor’s built-in Mail Merge dialog allows you to configure mail merge settings and start mail merge operations. Once the operation is complete, the control exports result to a file (using the specified format) and downloads the file to the local machine.
