PRB: Forms 2.0 CommandButton Fires Click Event When Disabled
ID: Q188766
|
The information in this article applies to:
-
Microsoft Internet Explorer (Programming) versions 4.0, 4.01, 4.01sp1
SYMPTOMS
The Forms 2.0 CommandButton control can be disabled by setting the value of
its Enabled property to false.
When this control is placed inside a table cell on a Web page, the Click
event for the control can be fired even though the control is disabled.
The Click event for the control cannot be fired if the control is disabled
and placed outside of a table.
CAUSE
The Forms 2.0 controls were designed and tested for use with Visual Basic and
Visual basic for Applications, not for Microsoft Internet Explorer.
RESOLUTION
- The recommended resolution for this problem is to use the intrinsic
button control by specifying the following HTML:
<INPUT TYPE=BUTTON ID=MyButton VALUE="My Button">
The following script disables the control when the page is displayed:
<SCRIPT LANGUAGE=VBScript FOR=Window EVENT=onload>
<!--
MyButton.disabled = True
-->
</SCRIPT>
- If you decide to continue using the Forms 2.0 CommandButton control, you
can check the Enabled property of the control when handling the Click
event, as demonstrated below:
<SCRIPT LANGUAGE=VBScript FOR=MyButton EVENT=Click>
<!--
if ( MyButton.Enabled ) then
MsgBox "MyButton_Click fired"
else
MsgBox "MyButton disabled"
end if
-->
</SCRIPT>
STATUS
This behavior is by design.
