Low performance in android with grid or chart

[Luca]

Hi all,

i have some page with 2-3 grid and avg of 10-20 items per grid or a chart.

i have a page that i use as a menu. It is a grid and each cell has an image withTapGestureRecognizer.

the problem is that on android the page load is very slow and freeze the UI even if i use async method (the loading indicator doesn't work, in ios yes)

How can i fix this?

thanks

Hi Alberto,

Thanks for using Syncfusion products.

We have checked the reported SfDataGrid loading performance issue in Xamarin.Forms with SfDataGrid v15.3.0.33 and Xamarin.Forms v2.3.3.180 but SfDataGrid has been loaded faster with Image in GridColumn and loaded two SfDataGrid in single page. For Your reference, we have attached our sample in the below location, please refer it. Could you please do revert us by modifying our sample to replicate the issue or share your sample along with replication procedure, also share your SfDataGrid product version and Xamarin.Forms version and loading time? these details will be help us to proceed further.

Regarding the query about chart related issue

Could you please update the chart related issue details or code snippet to provide the further assistance on this?

Hi Alberto, 

 

We are sorry about the inconvenience caused.   

 

We have tested our SfDataGrid by navigating to another view using Button clicked event and loaded new SfDataGrid in that navigation page and SfDataGrid has been loaded without delay in Samsung S8+ and MI Note 4 device. Could you please confirm whether you are using any custom view or custom template inside GridTemplateColumn and share your loading time? otherwise please revert our previously updated sample based on your requirement, that will be help us to proceed further.

hi, 

thanks for your reply.

i think you are using a high performance phone.

try with a standard one.

i'm using only GridTextColumn with something this

 <Setter Property="Foreground"  Value="{Binding TvsY, Converter={StaticResource cellStyleConverter}}" />

 public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

        {

            var amount = System.Convert.ToDouble(value);

            if (amount < 0)

                return Color.Red;

            else

                 if (amount > 0)

                return Color.Green;

            else

                return Color.Black;

        }

also with graph is slow.

on android i can't see the animation of loader that i see on IOS.
