Build a Simple VCL Application for SendGrid Data

How to build a simple VCL Application to view SendGrid data in RAD Studio using the CData FireDAC Components for SendGrid.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for SendGrid, you gain access to live SendGrid data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update SendGrid data. This article will walk through connecting to SendGrid and creating a simple VCL application with the Form Designer.

Creating a VCL Application for SendGrid Data

The following instructions show how to use the Form Designer to create a simple VCL Forms application that shows the basic FireDAC objects needed to connect to SendGrid from any application.

The following example populates a TDBGrid control.

  1. Create a new VCL Forms Application.
  2. Drop a TFDPhysSendGridDriverLink and TFDConnection object onto the form.
  3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.SendGrid" in the DriverId menu and configure the connection properties.

    To make use of all the available features, provide the User and Password connection properties.

    To connect with limited features, you can set the APIKey connection property instead. See the "Getting Started" chapter of the help documentation for a guide to obtaining the API key.

  4. Drop a TFDQuery object onto the form and set the properties below:

    • Connection - Set this property to the TFDConnection object, if this object is not already specified.
    • SQL - Click the button in the SQL property and enter a query.
    • Active - Set this property to true.
  5. Drop a TDataSource object onto the form and set the following property:

    • DataSet - In the menu for this property, select the name of the TFDQuery object.
  6. Drop a TDBGrid control onto the form and set the following property:

    • DataSource - Select the name of the TDataSource.
  7. Drop a TFDGUIxWaitCursor onto the form. This is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
