Hi to all!
I have created an UIBuilder for a contract class.
In the postBuild method, I've decleared a new FormBuildGroupControl (I want to add a button to my dialog):
Dialog dialogLocal; Form form; DialogGroup dialogGroup; FormBuildGroupControl groupBuildControl; super(); dialogLocal = this.dialog(); contract = this.dataContractObject() as MyContractClass; form = this.dialog().form();
usePrintManagement = this.addDialogField(methodStr(MyContractClass, parmMyFlag), contract);
dialogGroup = this.dialog().addGroup(#ButtonName);
groupBuildControl = this.dialog().formBuildDesign().control(dialogGroup.formBuildGroup().id());
buttonBuildControl = groupBuildControl.addControl(FormControlType::Button, #ButtonName);
myFlag = this.bindInfo().getDialogField(this.dataContractObject(), methodStr(myContractClass, parmMyFlag)); myFlag.registerOverrideMethod(methodStr(FormChecKBoxControl, modified), methodStr(myContractClass, myMethodOnModifiedFlag), this);
When I click on "myFlag" I want to activate/deactivate my buttonBuildControl.
Here the code of "myMethodOnModifiedFlag"
Share
Reportpublic boolean myMethodOnModifiedFlag(FormCheckBoxControl _checkBoxControl)
{
buttonBuildControl.enabled(any2enum(!_checkBoxControl.checked()));
return true;
}
But it does not work...any ideas?

That's what I tried to explain. Build controls are used when designing the form, not when it already runs. Look at which type you get from dialog.formRun().control() - it's not FormBuildButtonControl at all, it should be corresponding runtime control, FormButtonControl.
Changing build controls won't make any effect unless you use them to construct a new form (when they will be used to initialize the actual runtime controls).
As I also mentioned, I think that using a normal button won't work in all cases, such as opening the dialog from server.
Thank you Martin!
I've solved the problem!
The only change I've made is to put the following code
All responses (
Answers (
int ctrlId = dialog.formRun().controlId('OMSPrint');
FormControl control = dialog.formRun().control(ctrlId);
control.enabled(!_checkBoxControl.checked());
instead of buttonBuildControl.enabled(!_checkBoxControl.checked());
I think that the problem was that the UIBuilder does not recognize my buttonBuildControl.
Why? I don't know...
The key problem with your code seems to be that you're trying to use form build controls when the form already runs. It would work for setting property values before executing the form, but after that build controls aren't used anymore.
You could use something like the following code, although it would clearly need some improvements before using in production. Note that I'm using a standalone class for simplicity, not a UI builder.
class DialogTest
{
Dialog dialog;
FormBuildButtonControl buttonBuildControl;
public void new()
{
dialog = new Dialog();
}
public static void main(Args _args)
{
new DialogTest().run();
}
private void run()
{
DialogField myFlag = dialog.addField(extendedTypeStr(NoYesId));
myFlag.registerOverrideMethod(methodStr(FormCheckBoxControl, modified), methodStr(DialogTest, myMethodOnModifiedFlag), this);
// Just a random menu item for demonstration
dialog.addMenuItemButton(MenuItemType::Display, menuitemDisplayStr(Batch));
dialog.run();
}
public boolean myMethodOnModifiedFlag(FormCheckBoxControl _checkBoxControl)
{
int ctrlId = dialog.formRun().controlId('MnuItm_1');
FormControl control = dialog.formRun().control(ctrlId);
control.enabled(!_checkBoxControl.checked());
return true;
}
}
Note that normal buttons (not menu item buttons) don't seem to be supported by the dialog class at several places, such as in Dialog::addControls().
In general, dialogs are intended for input fields. If you need things like buttons, maybe you should be using a normal form.
By the way, your code above seem to be using the same name for two controls (the group and the button).
Hi Martin! Thank you for the answer.
I've changed my code from buttonBuildControl.enabled(any2enum(!_checkBoxControl.checked())) to buttonBuildControl.enabled(!_checkBoxControl.checked())
I've put a breakpoint and the method gets called.
With the debugger I've seen the ButtonBuildControl properties, and the property "Enabled" ist set correctly (with Yes/No).
What I'm doing wrong?
First of all, collect more information about what happens. Does your method gets called at all? That's a very important piece; you should follow very different directions depending on the answer.
By the way, this is a strange piece of code: buttonBuildControl.enabled(any2enum(!_checkBoxControl.checked())). If you believe that it's necessary to convert the value to boolean, using the exclamation mark makes no sense, because it would have to convert the value to boolean even before your conversion. In fact, both enabled() and checked() use the same type (boolean), therefore no conversion is needed.
