Custom function with SfPopUp how wait ???

Hi,

I´m create custom function that have screen interaction, to permit user define interaction from cell.

But when made SfPopUp.Show() , this can´t wait SfPopUp end to return and continue program. Custom Function ended before SfPopUp

Thanks in advance for any help.

Custom function Example :

public string InputRB(string args)
        {
            strReturn = String.Empty;
            var splitArgs = args.Split(new char[] { CalcEngine.ParseArgumentSeparator }); 

            DataTemplate templateview = new DataTemplate(() =>
            {
                StackLayout slMain = new StackLayout();
                SfRadioGroup radioGroup = new SfRadioGroup();
                foreach (var item in splitArgs)
                {
                   SfRadioButton rb = new SfRadioButton();
                    rb.Text = item;
                    rb.StateChanged += RadioButton_StateChanged;
                    radioGroup.Children.Add(rb);
                }
                slMain.Children.Add(radioGroup);
                return slMain;
            });


            PopUpInput ppcnt = new PopUpInput();
            SfPopupLayout pplt = ppcnt.Content as SfPopupLayout;
            pplt.PopupView.ContentTemplate = templateview;
            pplt.Show(); /* returning from SFPopUp without wait SFPopUp close. */
            return strReturn;
        }
        private void RadioButton_StateChanged(object sender, StateChangedEventArgs e)
        {
            strReturn = (sender as SfRadioButton).Text;
          
        }

Hi Carbonete,  
  
Thanks for using Syncfusion support.  
                                                                 
We have checked your query. In that, we have loaded the radio button as content in popup, while clicking the radio button the popup does not close. If your try to perform any action while popup in the view, the popup will close, it is the behavior of the popup. We have prepared the sample based on your requirement and attached the same for your reference. You can download the sample from the below link.

Hi,

Sorry but this is not the answer . You not put any instruction after   popupLayout.Show();

If you make this , you see instruction execute and popup continue open.

private void ClickToShowPopup_Clicked(object sender, EventArgs e)
        {
            popupLayout.Show();
            string s = " this execute and popup still open";
        }

In my sample.

return strReturn;

  executed and popup not closed.

I  want instruction after Show execute only after  popup  closed.

Remenber that popup is showed inside a Calculate function and if not wait popup close, function ended and return no value.

Thanks for your atention.

Make you callback async and do this

private async void ClickToShowPopup_Clicked(object sender, EventArgs e)
        {
                popupLayout.IsOpen = true;
                while (popupLayout.IsOpen)
                {
                     await Task.Delay(100);
                }
               string s = " this execute AFTER popup closed";
        }

Sorry, i think you can't understand or i can´t be clear in my need.  
I need a synchronous PopUp.

I need a behavior like  to win32 Messagebox or Win32 OpenFIledialog .

Next intruction not executed until Dialog closed. 

Examples :
