Mark selected/current record in a datablock [message #244326]

Hi guys,

I have a Database Block that retrieves a set of records from my DB table.

I want to have the Block to behave somehow like an LOV in a way that when I select a record and press a button, I can pass the record to another form.

I have created a NON database item Radio button for each record but I am missing the functionality, when I click on the radio button corresponding to the record I am not being able to activate/set the current record and besides ONLY ONE Radio Button must be selected at on time (this is not working either...!!)

Attached is a Screen shot of the Form.

Can someone please help me on getting this functionality, or if there is better alternative to do the work.

Many thanks in advance.
Baz

I would suggest using a checkbox instead of the radio button.

When you press the 'Movement Detail' button you would build a string containing the key field data, probably separated by commas, and pass that to your next form.

Do you need to do the work in another form or can you do it on a second canvas in this form, and activate it by setting the checkbox?

Thanks David,

I always found your posts beneficial. Can you please elaborate more on your approach. My concerns are the following:

1) When I click on one of the Checkboxes, how do I restrict ONLY one checkbox to be active? Only one records to be selected, i.e. deactivate all others? Is it a Checkbox Property Item or programatically?

2) How do I associate the Check box with the corresponding Record since it is NOT a DB item?

3) When I press the "Movement Details" button, basically I need to pass the MVT_ID from which I can retrieve all the related data from the DB. Do I still need to build a String for that? I am planning to use a ParamList.

How can my checkboxes handle 1 + 2? Please can you provide more details?

Many thanks again,
Baz

Add the checkbox as a non-database item to your main block. In the 'When-Checkbox-Changed' trigger, make a note of the record on which you are currently resting (have a non-database entry in a 'control' block to store the row number), either loop through all the other rows and turn them off, then come back to this row and turn it on, or use a second 'control' block item into which you recorded the number of the previous 'checked' row, go to it, turn the checkbox 'off', then come back.

If you are only passing one value you don't need to build a list. Just populate the parameter and pass it.

Thanks David, you're the man (Y)

WORKS Perfectly fine. Laughing

IF (:CONTROLITEMS.STORED_RECNUM IS NULL) THEN
:CONTROLITEMS.STORED_RECNUM := :System.Cursor_Record;

Message('The FIRST Record Number is: '||:CONTROLITEMS.STORED_RECNUM);

ELSE
	TEMPREC := :System.Cursor_Record;
	Message('RECORD# 2 is: '||TEMPREC);
	Go_RECORD(:CONTROLITEMS.STORED_RECNUM);
	:AREA3_MVTS.SELECTED_RECORD :='N';
	
	
	Go_RECORD(TEMPREC);
	:CONTROLITEMS.STORED_RECNUM := TEMPREC;
	
END IF;

I appreciate your support.
