How do I initialize a radio button group

[Les]

I have a radio button group used to display all or a selection of records. When the user changes the selection, the selection is modified dynamically and the status is saved in a preferences table. For each selection, I change the color of the radio button text for emphasis. When the form is activated, I want the radio button to display the saved choice correctly and the correct color for that choice. How do I modify the properties to do this?

Presumably the radio button control is bound to a variable. Populate that variable with the desired value and the control should display it.

Re: How do I initialize a radio button group

The 1st part of your post seems to suggest you have already done this. Then you ask how to do it? I'll assume that you have not yet done this but wish to.

You can bind the RC to a field w. fixed choices. But you cannot change the color of individual radio selections. You can (I have never tested this) change the font color for the RC as a whole, I believe. If your RC object is called "radio1", you might try something like:

radio1.font.color = "red"

You could put in the RC's OnChange event inside a case statement. Something like:

Select
   Case this.value = "UPS"
          radio1.font.color = "brown"
   Case this.value = "FedEx"
          radio1.font.color = "red"
   Case this.value = "USPS"
          radio1.font.color = "blue"
End Select

Then in the form's onfetch event:

Select
   Case radio1.value = "UPS"
          radio1.font.color = "brown"
   Case radio1.value = "FedEx"
          radio1.font.color = "red"
   Case radio1.value = "USPS"
          radio1.font.color = "blue"
End Select

P.S. There is also a "trick" method where you can change the font color individually for each choice. But it's a little more work.

Peter,
Would that be just by using two separate radio fields side by side with the border edges that meet turned off so that it looks like one--enabling the individual control of each radio field??....or is there another way? (hoping there is!!) :)

Correcto, Mike! Sorry. BTW: "Two" or more. One could also use a text object or text variable to "highlight" the result w. the color/label of your choice

Re: How do I initialize a radio button group

Tom, Peter,

I can dynamically get the control to do what I need. The problem is getting it to initialize properly the next time the form is loaded.
On activate, I populate the variable according to the saved value. The control does not show the correct status. I set the colors so choice one is different from choice two and if neither to a third color. The third color always shows on activation until a button is pressed. I have tried .push() and a lot of other form methods but no joy.
Is there some method that will force the control to reinitialize that I have overlooked?

Re: How do I initialize a radio button group

Would <object>.REFRESH() help? After you set your variable, try a refresh. I'm new to A5 so I'm just putting a bunch of stuff on forms to try them out. I added a text input object to the form and assigned a variable to it. In a dropdown list I assigned the value of my selection to the variable of the text input object. The value would not display on the form until I did an object.refresh()

Thanks David. That didn't work either.

Re: How do I initialize a radio button group

So Les,
What do you want it to do...

I set the colors so choice one is different from choice two and if neither to a third color

which I believe is happening from what you said...

The third color always shows on activation until a button is pressed

I guess I don't understand the problem....unless a radio button has been chosen and the color did not show appropriately..if so try how I did it in the following.

Regardless, I found that having a field based on the same variable on the form and using its value was much easier to control and no "refresh" issues...and can then simply hide the field from view.

EDIT: with code similar to
--where Svradio0 is the field
--where Svradio and Svradio1 are the actual radio buttons

topparent.commit()
if topparent:Svradio0.value = "City" then 
	topparent:Svradio.Font.Color ="red"
    topparent:Svradio1.Font.Color ="black"
  else if topparent:Svradio0.value = "State" 
    topparent:Svradio.Font.Color ="black"
    topparent:Svradio1.Font.Color ="blue"
  else
    topparent:Svradio.Font.Color ="black"
    topparent:Svradio1.Font.Color ="black"    
end if

Re: How do I initialize a radio button group

OK. I figured out a way. In onactivate for the form, I issued a .push() for the radio group button and then added some code in the onpush event to modify the font and other settings. I thought I had done that properly earlier but it wasn't working. Works OK now. Thanks for all the help.
