Greeting everyone

I've created a new button
and i override button clicked() on my extension form

because i want add condition before user clicked on post button

so then i override a clicked method of a button

to my class

class MycustomPriceDiscAdm_Form_Handler
{
    
    /// 
    ///
    /// 
    /// 
    /// 
    [FormControlEventHandler(formControlStr(PriceDiscAdm, NewPostButton), FormControlEventType::Clicked)]
    public static void NewPostButton_OnClicked(FormControl sender, FormControlEventArgs e)
    {
        PriceDiscAdmTrans   priceDiscAdmTrans;
        FormRun             formRun=sender.formRun() as formRun;
        FormDataSource      priceDiscAdmTrans_ds;

        priceDiscAdmTrans_ds=sender.formRun().dataSource(1);
        priceDiscAdmTrans=priceDiscAdmTrans_ds.cursor();

        MenuFunction menuFunction;

        menuFunction = new MenuFunction(menuItemActionStr(PriceDiscAdmPost), MenuItemType::Action);

        menuFunction.run();


    }

}

but i got this error when i clicked on my button

Add args

Args args = new Args(); args.record(priceDiscAdmTrans); menuFunction = new MenuFunction(menuitemActionStr(PriceDiscAdmPost), MenuItemType::Action); if (menuFunction && menuFunction.checkAccessRights()) { menuFunction.run(args); }

Hi mohammed,

you seem to be calling menu item PriceDiscAdmPost without providing any buffer with args. That's why you get the error.

Perhaps you would like to send priceDiscAdmTrans buffer but you forgot to add such code?

Did you so far debug your code? You should be able to catch these issues by debugging.

Your code is clearly executed because you get the error messages. And you even get a different error message now, than before changing your code. You don't see event handlers in the form designer in Visual Studio. Just debug your code and you will find what's wrong. If you need any more help, please share all the details that you learned while debugging. If you need help in learning how to debug, please search the web - you'll find all the information that you need.

However, I don't understand why you simply didn't add a MenuItemButton, pointing to PriceDiscAdmPost menu item. You don't need any code to call menu items from forms..

should I indicate that as extension

like add this above my code?

[ExtensionOf(formControlStr(PriceDiscAdm,NewPostButton))

class MycustomPriceDiscAdm_Form_Handler { ///
/// ///
/// /// [FormControlEventHandler(formControlStr(PriceDiscAdm, NewPostButton), FormControlEventType::Clicked)] public static void NewPostButton_OnClicked(FormControl sender, FormControlEventArgs e) { PriceDiscAdmTrans priceDiscAdmTrans; FormRun formRun=sender.formRun() as formRun; FormDataSource priceDiscAdmTrans_ds; Args args = new Args(); MenuFunction menuFunction; SystemNotificationDataContract notification = new SystemNotificationDataContract(); args.record(priceDiscAdmTrans); priceDiscAdmTrans_ds=sender.formRun().dataSource(1); priceDiscAdmTrans=priceDiscAdmTrans_ds.cursor(); menuFunction = new MenuFunction(menuitemActionStr(PriceDiscAdmPost), MenuItemType::Action); if (menuFunction && menuFunction.checkAccessRights()) { menuFunction.run(args); } } }

No, event handlers and _Extension classes are completely separate things, you should not mix them.

I think it's best to wait for your inputs from the debugging results before proceeding any further.
