List Form - Allow only one record to be selected

doddwell

Hello

I have a list form that displays a list of Batches. I have a menu button on the form that allows the user to Post, Cancel or View Batch Documents. I want to prevent the user from being able to Select more than one record. If this is not possible, what's the best way of performing a count of the selected records when the user presses the menu button?

Thanks very much.

you could either use

CurrForm.SETSELECTIONFILTER(YourRec);
IF YourRec.COUNT <> 1 THEN ...

OR
just use the current Rec for following code and dont loop throught all the data

Thanks SonGoten13

The first method works for me. I amended it slightly though. After using the SetSelectionFilter function, my batch list form is filtered to the users selection and I don't want this...so my code now looks like this:

RetroDiscbatch.COPY(Rec);
CurrForm.SETSELECTIONFILTER(RetroDiscbatch);

IF RetroDiscbatch.COUNT > 1 THEN
ERROR('Count : %1',RetroDiscbatch.COUNT);

Hi Doddwell,
yup, that will work.
But do notice one thing in SonGoten's reply.
He did NOT put in "Rec" as the parameter to SETSELECTIONFILTER, but instead a new variable, similar to the RetroDiscbatch.
(...Retro Disco... makes me want to dance... \:D/ \:D/ )

so you could amend your code one step further:

//RetroDiscbatch.COPY(Rec);  //not needed
CurrForm.SETSELECTIONFILTER(RetroDiscbatch);

IF RetroDiscbatch.COUNT > 1 THEN
ERROR('Count : %1',RetroDiscbatch.COUNT);
