To download DevExpress Delphi components, you need to have a valid license or a trial account. You can purchase a license or register for a trial account on the DevExpress website. Once you have a license or a trial account, you can log in to the DevExpress Client Center and go to the Download Manager section. There you can find the latest version of DevExpress Delphi components and download the installer file.


To install DevExpress Delphi components, you need to run the installer file that you downloaded from the DevExpress Client Center. The installer will guide you through the installation process and let you choose which components and features you want to install. You can also customize the installation path and the IDE integration options. After the installation is complete, you need to restart your Delphi IDE to load the DevExpress components.


Now you can use DevExpress Delphi components in your projects. You can find them in the Tool Palette under the DevExpress category. You can also access the documentation, demos, and support resources from the DevExpress menu in the IDE. To learn more about DevExpress Delphi components and how to use them, you can visit the DevExpress VCL Documentation website.


In this section, we will show you some examples of how to use DevExpress Delphi components in your projects. We will use the TChartControl component to create a simple chart and the TcxGrid component to display and edit data in a grid.


Creating a Chart with TChartControl




To create a chart with TChartControl, you need to do the following steps:


  • Drop a TChartControl component from the Tool Palette onto your form.



  • Select the TChartControl component and go to the Object Inspector. In the Properties tab, expand the Series property and click on the ellipsis button (...) to open the Series Collection Editor.



  • In the Series Collection Editor, click on the Add button to add a new series. You can choose from different types of series, such as line, bar, pie, area, etc. For this example, we will use a line series.



  • Select the line series and go to the Object Inspector. In the Properties tab, you can customize the appearance and behavior of the series, such as color, width, style, markers, labels, etc. For this example, we will change the Name property to "Sales" and the Color property to "clRed".



  • Close the Series Collection Editor and go back to your form. In the Object Inspector, expand the Data property of the TChartControl component and click on the ellipsis button (...) to open the Data Editor.



  • In the Data Editor, you can add data points to your series. You can either enter them manually or load them from a data source. For this example, we will enter some sample data points for the Sales series.



  • Close the Data Editor and run your application. You should see a chart with a red line showing the Sales data.
