DB Daniel Basazinew July 26, 2019 06:28 AM UTC

hey Subburaj 

Thanks for update , the issue is not solved still. as u see from the code snippet i sent you before i did it correctly and again i tired with your code snippet but nothing changed.

FYI - am still using the Patched version that you send me before on the min max issue. if that was the case i can upgrade to the latest essential studio. did the latest essential studio and the nuget package solve the min max issue ?  if the issue is patched with your current version i can use that and check the Arabic issue. 

thanks

DB Daniel Basazinew July 26, 2019 10:58 AM UTC

i just tested the latest 17.2.0.36 nuget package with demo app and the Arabic issue solved but this nuget package uses .NET Standard for code sharing but in our project we use .NET Framework we have no plan now to upgrade to standard b/c our app go live soon and its huge. to use 17.2.0.34 nuget package the min max issue still exists so what we can do to solve both issues? or u can give us the latest package that supports .NET framework. or find any solution . b/c we are going to purchase the product.



SP Subburaj Pandian Veluchamy Syncfusion Team July 29, 2019 10:01 AM UTC

Hi DanielBasazinew,  
    
Thank you for the update. 
 
Regarding issue fix: Throws exception when Min / Max date set and while tapping 
This issue fix has been included in our weekly NuGet update version 17.2.0.35, so you can use the same version or latest version 17.2.0.36. 
 
Regarding Arabic locale issue and .net standard 2.0:  
This issue is because of compilation restriction in the project that targetsnetstandard2.0, since our control targets netstandard 2.0 from the release update 17.2.0.28 beta and as you’re using older pcl application net framework. It can be resolved by adding netstandard.dll in the PCL project. Please get the assembly from the following location, 
 
Location: C:\Program Files\dotnet\sdk\2.1.202\Microsoft\Microsoft.NET.Build.Extensions\net461\lib\netstandard.dll 
 
Overall as a solution, we suggest you to use our latest Syncfusion update version 17.2.0.36 and add the netstandard.dll in the PCL project of your application. Please attach this assembly and let us know, whether the mentioned issue is resolved.  
 
Regards,
Subburaj Pandian V  


DB Daniel Basazinew July 29, 2019 01:13 PM UTC

DB Daniel Basazinew August 5, 2019 05:06 AM UTC

hey Muneesh

as you can see we use our own DataTemplate but nothing is shown in the page please kindly refer the xaml page i sent you before. the data we bind in the item source are correctly retrieved we checked that. does the coursel page use entire page ? even when i add a tool bar item in the page the tool bar item is not shown. we purchase your product and we didn't  expect like these. and u can set a call today and you can refer our code.  

MK Muneesh Kumar G Syncfusion Team August 6, 2019 09:21 AM UTC

MK Muneesh Kumar G Syncfusion Team August 7, 2019 07:00 AM UTC

Hi Daniel, 
 
We have checked the SfCarousel with latest Xamarin.Forms. Unfortunately, the issue is not reproduced in our side. As we promised in the meeting, we have prepared the same XAML structure with SfRotator Control. Please have the sample from the below link, 
 
 
Thanks,

DB Daniel Basazinew August 7, 2019 08:32 AM UTC

hey Munnesh 

Grettings 

I want to send you a pictorial representation of the issue. pls kindly refer the attached screen shots and analyze them why the carousel view itself and the items inside is not shown in the page.

FYI - the page first generates a barcode. you can see in the screen shots. 
At the moment  i checked the rotator on demo app and am inserting to the project. so can u check this file pls,

Regards 
Daniel

DB Daniel Basazinew August 8, 2019 07:52 AM UTC

hey Munnesh

I tired so far with this issue and i guess i found it now. when i push the page form viewmodel it didnot display the items inside the rotator but when i push the page from xaml.cs by using Navigation.PushModalasync(); method it works. to push form the view model we have custom implementation of pushasync and pushmodalasync events. here is the code sniipet 

form code behind --
 private void Button_Clicked(object sender, System.EventArgs e)
        {
            Navigation.PushAsync(new BoardingPage());
        } 

from Viewmodel

async Task OnBoardingPassCommand_clicked()
        {
            var boardingpage = new BoardingPage();
            await Shared.PageService.GetPageServiceInstance.OnPushAsync(boardingpage);   //this method is our custom implenation Based on xamarin forms Naviagtion
        }




DB Daniel Basazinew August 8, 2019 11:13 AM UTC

so can you show me a demo that push a page from viewmodel. and the page contains the rotator veiw with some static Datas?
today Muneesh please?

MK Muneesh Kumar G Syncfusion Team August 8, 2019 02:11 PM UTC

Hi Daniel, 
 
We have prepared a simple sample using SfRotator Control to navigate to the another page with SfRotator Items added using ViewModel, it works fine. Please have the sample from the below link,

Sample Link : https://www.syncfusion.com/downloads/support/directtrac/general/ze/RotatorSample_(1)-214547394

We have used the below code to navigate to the next page, 
 
 public RotatorViewModel(INavigation navigation)
        {
            _navigation = navigation;
           ClickCommand = new Command(
           execute: () =>
           {
               var myPage = new MyPage();
               navigation.PushAsync(new MyPage());
           },
           canExecute: () =>
           {
               return true;
           });
            ImageCollection.Add(new RotatorModel("Calculator.png", "Calculator"));
            ImageCollection.Add(new RotatorModel("Camera.png", "Camera"));
            ImageCollection.Add(new RotatorModel("Excel.png", "Excel"));
            ImageCollection.Add(new RotatorModel("GMail.png", "GMail"));
         
        } 
 
  
 If you still need to use the below code 
 var boardingpage = new BoardingPage(); 
            await Shared.PageService.GetPageServiceInstance.OnPushAsync(boardingpage); 
  
Please provide the complete code files used our Syncfusion components, this would be helpful for us to give better solution in this.  
  
Thanks,  
Muneesh Kumar G.

Hi Daniel,

 

We have checked with your query, we are not able to reproduce any delay or performance issue on selecting a date in Xamarin.Forms iOS with latest calendar version. Could you please confirm whether you are selecting single or multiple range of dates? Also, could you please confirm your current calendar version and elaborate your query by providing more information about the performance issue? So that, it will be helpful for us to analyze and provide you better solution.
