PRB: DBGrid Has No Default Property

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic for Windows, 16-bit and 32-bit, version 4.0

SYMPTOMS

Attempting to use the default property of the DBGrid control results in the error:

   Run-time error '438':
   Object doesn't support this property or method

CAUSE

Despite what the Programmer's Guide and the online help say, the DBGrid control has no default property. The default value for the standard, data unaware, Microsoft Grid control is Text. That property was erroneously listed in the Programmer's Guide as the default property for the DBGrid control.

RESOLUTION

Refer explicitly to any properties of the DBGrid control you want to use.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce

1. Start Visual Basic.

2. On the File menu, click New Project.

3. Double-click the DBGrid icon in the Toolbox to add a new data-bound grid to your project.

4. On the Run menu, click Start (ALT, R, S) or press F5. Press CTRL+BREAK, or press the PAUSE button to pause execution of the program. In the debug window, type the following

         Print DBGrid1
   

   and press ENTER. Visual Basic should output the value of the default property of the DBGrid control. However, since the DBGrid control has no default property, Visual Basic will give the error mentioned above.
