Visual Basic: DataGrid Control
Error Event (DataGrid Control)
See Also Example Applies To
Occurs only as the result of a data access error that takes place when no Visual Basic code is being executed.
Syntax
Private Subobject_Error([ indexAs Integer,] ByValdataerrorAs Integer, responseAs Integer)
The Error event syntax has these parts:
| Part | Description |
| object | An object expression that evaluates to an object in the Applies To list. |
| Index | An integer that identifies a control if it is in a control array. |
| dataerror | An integer that identifies the error that occurred. |
| response | An integer that may be set to 0 to suppress error message display, as described in Settings. |
Settings
The settings for response are:
| Setting | Description |
| 0 | No error message will be displayed. |
| 1 | (Default) The message associated with the error will be displayed. |
Remarks
Even if your application handles run time errors in code, errors can still occur when none of your code is executing, as when the user clicks a Data control button or changes the current record by interacting with a bound control. If a data access error results from such an action, the Error event is fired.
Not adding code to this event is equivalent to setting the response argument to 0.
Note Use the ErrorText property to retrieve the error string that will be displayed.
