Hi Tamas, 

 

Thank you for contacting Syncfusion support. 

 

Based on the provided information, we have checked your requirement of waiting asynchronously when closing the Popup layout by clicking accept / close option in Xamarin.Forms can be achievable by setting delay in the Closing event of PopupLayout. This event will while closing the Popup layout, using Cancel argument you can handle whether to close Popup or not. Please refer the following code example for the same, 

 

[c#] 

popupLayout.Closing += PopupLayout_Closing; 

… 

        private void PopupLayout_Closing(object sender, System.ComponentModel.CancelEventArgs e) 

        { 

            var delay = System.DateTime.Now.AddMilliseconds(2000); 

            while (true) 

            { 

                if (System.DateTime.Now >= delay) 

                { 

                    e.Cancel = false; 

                    break; 

                } 

            } 

        }

hello.thanks for the reply.No that is not the case I was looking for. 

The question is whether we can show the popup asynchronously or not.

Please find the following case:

if (!isValidPwd)

{

StopSpinningOperation();

var syncFusionConfirm = new SyncFusionAlert(string.Empty,

string.Format(AppResources.CHECK_NETWORK_KO, lcWiFiData.SSID),

xx.Localization.AppResources.CONTINUE,

xx.Localization.AppResources.CANCEL);

syncFusionConfirm.PopupView.DeclineCommand = new Command(() => { return; });

syncFusionConfirm.Show();

//DoStuff

}

I only want to execute the //DoStuff part when the user has hit accept(because as you can see on decline we want to exit the method syncFusionConfirm.PopupView.DeclineCommand = new Command(() => { return; }); ).

But in order to be able to achieve this,we need to wait until the user has hit accept or decline and not to continue with the flow until then.

How can we achieve this?

Thanks,Norbert

Note: //DoStuff is a complicated part ,and it does not work to put it in the AcceptCommand, we need to execute that after the popup has been "resolved"/closed.

Hi Tamas, 

Thanks for the update. 

We have analyzed the reported query and you can perform your additional operation when popupview is open by using the Opened event in Xamarin.Forms. 

[C#] 

popupLayout.Opened += PopupLayout_Opened; 

 

private async void PopupLayout_Opened(object sender, EventArgs e) 

{ 

// Codes that needs to be executed once popup is visible in the screen. 

} 

 

We have prepared sample for your requirement please follow the below link.
