Lesson 26: Using Microsoft DataGrid Control 6.0

In the previous chapter, we use textboxes to display data by connecting them to a database via Microsoft ADO data Control 6.0. The textbox is not the only control that can display data from a database, many other controls in Visual Basic can display data. One of the them is the DataGrid control. DataGrid control can be used to display the entire table of a recordset of a database. It allows users to view and edit the data.

DataGrid control is the not the default item in the Visual Basic control toolbox, you have add it from the VB6 components. To add the DataGrid control, click on the project in the menu bar and select components where a dialog box that displays all the available VB6 components. Select Microsoft DataGrid Control 6.0 by clicking the checkbox beside this item. Before you exit the dialog box, you also need to select the Microsoft ADO data control so that you are able to access the database. Lastly, click on the OK button to exit the dialog box. Now you should be able to see that the DataGrid control and the ADO data control are added to the toolbox. The next step is to drag the DataGrid control and the ADO data control into the form.

The components dialog box is shown below:


   

Before you proceed , you need to create a database file using Microsoft Access. Here I created a file to store my the information of my books and I name the table book. After you have created the table, enter a few records such as mine. The table is shown below:

 Now you need to connect the database to the ADO data control. To do that, right click on the ADO data control and select the ADODC properties, the following dialog box will appear.

   

 

Next click on the Build button and the Data Link Properties dialog box will appear (as shown below). In this dialog box, select the database file you have created, in my case, the file name is books.mdb. Press test connection to see whether the connection is successful. If the connection is successful, click OK to return to the ADODC property pages dialog box. At the ADODC property pages dialog box, click on the Recordsource tab and select 2-adCmdTable under command type and select book as the table name, then click OK.

 

 

 

Finally you need to display the data in the DataGrid control. To accomplish this, go to the properties window and set the DataSource property of the DataGrid to Adodc1. You can also permit the user to add and edit your records by setting the AllowUpdate property to True. If you set this property to false, the user cannot edit the records. Now run the program and the output window is shown below:
