SYMPTOMS

Setting the Alignment property of a column in a DBGrid control at design- time, before selecting Retrieve Fields, results in the grid not showing any data when the application is run.

RESOLUTION

At design time, select Retrieve Fields from the custom control property dialog box. Any changes made to the Alignment properties of columns in the grid will no longer cause this problem. If the DatabaseName and RecordSource properties of the data control are not known until the program is run, using Retrieve Fields won't be an option. In this case, just set the Alignment property of the column(s) in question at run time, like this:

   DBGrid1.Columns(0).Alignment = 2      'select center alignment

STATUS

Microsoft has confirmed this to be a issue in the Microsoft products listed at the beginning of the article. We are researching the problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Problem

Start Visual Basic.
From the File menu, choose New Project.
Click the DBGrid button in the Toolbox and drag a new DBGrid control onto the form.
Double click the data control button in the Toolbox to add a data control to the project.

Set the following properties of the data control:

   DatabaseName: path to your vb directory\biblio.mdb
   RecordSource: Authors

Set the DataSource property of the DBGrid control to Data1.
Right-click the DBGrid control and select 'Properties...' to display the DBGrid's property dialog box.
Click the Columns tab, and change the Alignment property of the first column to '2 - Center'. Press OK to keep changes.
From the Run menu, choose Start (ALT, R, S) or press the F5 key. The application will start and the DBGrid will be displayed with the text insertion icon in the center of the first cell. However, no data will be visible. Printing out the contents of a cell's Text property gives an empty string. Stopping the program, selecting 'Retrieve Fields', and starting again fixes the problem.
