Description
This sample demonstrates the use of a TBindGridLink.
This sample uses LiveBindings to bind a TDBNavigator with a TStringGrid and other controls.
How to Use the Sample
- Navigate to Start | Programs | Embarcadero RAD Studio Athens | Samples, go to Object Pascal\LiveBindings\bindgridlink\vcl, and open BindGridLinkVCLProject.dproj.
- Press F9 or choose Run > Run.
- When you run the application, the main window displays the visual components of the sample. Initially, the components display the first item of the dataset.
- Use the TStringGrid to navigate through the dataset.
- Ensure the Active TCheckBox is checked to navigate through the dataset also using the TDBNavigator.
- See how the rest of the visual components update when navigating through the dataset.

Implementation
- Use the TDBNavigator or the TStringGrid to navigate through the dataset. Ensure the Active TCheckBox is checked to navigate through the dataset using the TDBNavigator.
- TBindingsList is used to create managed binding among the different components.
- The TImage displays the image of the selected fish.
- The two TEdit and the TLabel display the Category of the selected fish within the dataset.
- TBindGridLink is used to bind the TStingGrid and the TBindSourceDB.
