reset radio button in DCT

Amit_LnT

Hi,
this may be a simple way.. but i think i m lost here..
Could someone help me in resetting a radio button in DCT with formapi ?
I want the radio button selection as false on an event of a field change.

thanks,
amit

Amit, this is trivial.

What have you tried ? The only catch is that instead of setting the actual value (False) you set the specific entry of False (0 for the 1st, 1 for #2, etc)

It is a little more complicated if you allow mulitples.

Hi Andy,
I am not trying to set any option. What i need is, on an event i should be able to clear the selection. So the user has to select the radio button again.

I have tried it following way.. but nothing works..
var optionsArray = IWDatacapture.getItem(itemName).getOptions();
optionsArray[0].selected = false;
optionsArray[1].selected = false;
OR
var optionsArray = IWDatacapture.getItem(itemName).getOptions();
optionsArray[0].checked = false;
optionsArray[1].checked = false;

Amit, you are close. The options array you are getting is a stand alone array, it is not a pointer to the options for the item. Once you modify the options array, you need to call IWDatacapture.getItem(itemName).setOptions(optionsArray) to actually set the new options.

Basically one of 2 ways, to CLEAR all selections, use Jeff's approach. If you want the 1st selection chosen (or a default choice) it is easier, radioItem.setValue(0);
will make the 1st option selected.

As far as I recall Amit is on 6.5. If that's the case, Jeff's approach is the only one that'll work on radio buttons and drop-downs.
There is a little glitch in 6.5 FormAPI that makes reset mandatory. setValue changes options all right. Visually nothing changes though until you set options.
Note that this sad fact contradicts TS 6.5 FormAPI Documentation.

I'm not a big fan of using setValue on anything but text fields. For radio, checkbox and select items, I always use setOptions. I think it's more likely that something could break in an upgrade with setValue than setOptions.

Just my $.02.

So you know what everyone on DevNet runs ? Since Amit did not specify what level of TS he is using I did assume (and mentioned 6.7.1 in a prior post). Smiley Very Happy

& Jeff, I happen to be lazy, actually, extremely lazy, so if there is an easier way to do it, I will use it. You must be paid by the hour, or line of code. Smiley Tongue

Nay, just looked at his previous thread (Login Event). He's indicated 6.5 there. He could be working in a mix, do a transition, who knows...

Amit_LnT

sorry guys..
my mistake.. i should have mentioned the env.. Smiley Happy

yes.. Boris is right... I am working on TS 6.5 sp2.
and i tried Jeff's suggestion.. and it worked...
(wonder.. y..i haven't tried that.... may be my cup is full today...)..

thanks you all guys...

cheers,
