Checkbox in DataWindow

[s***@yahoo.com]

I have a datawindow that will typically have 3 to 4 rows, each row will
have a different client address. Each row will also have a default
checkbox. When one is checked, how can I disable the checkboxes in the
other rows. Thanks.

itemchanged event - scroll through the rows that are not the 'row'
value triggering the itemchanged event
set them to dw_1.Object.<column_name>.checkbox.off, that way when they
choose one they can not choose another but they can calso change thier
mind.

for i = 1 to this.rowcount()
if i = getRow() continue
dw_1.Object.<column_name>.checkbox.off
next

Thanks for the help.

I tried it and nothing happened. I also tried setting the row:

li_row = getRow()
for i = 1 to this.rowcount()
if i = li_row Then continue
dw_sheet.SetRow(i)
dw_sheet.Object.default_indicator.checkbox.Off
next

Any thoughts?

Checkbox is just a presentation style. You have to setItem the value which
corresponds to 'on' or 'off' state of a checkbox. And setRow is not necessary.

Thanks Konstantin

This worked:

IF Dwo.name = "default_indicator" THEN
for i = 1 to this.rowcount()
if i = getRow() Then continue
dw_sheet.SetItem(i, "default_indicator", "N")
next
End IF

Hi,
what about a global variable (long gl_checkboxrow) which is set to the
actual rownumber when the checkbox in the actual row is checked or -1 if
the row is unchecked (e.g. the itemchanged event of the datwindow control).
Then in your Datawindow Column which holds the checkbox you can code (in
the expression painter) something like if rownum <> gl_checkboxrow and
gl_checkboxrow <> -1 then thisrow.uncheck.
Sorry for the Pseudocode, but at home I dont have acces to a Powerbuilder
Development Environment.

That makes sense. I'm not sure how to code that in the expression
painter but I'll give it a try. Thanks for the help.
