Custom view not working in release mode on Android

[Omar]

Hi,

In my main project, I am using an SfPicker with a custom view via the ItemTemplate parameter, and I am encountering the following issue on Android:

- In debug mode: everything works fine.

- In release mode: the picker does not display anything.

I created a small project (attached) to test this, and I am experiencing the same issue:

Debug :

Release :

Thanks for your assistance.

Hi Omar,

In SfPicker, the binding context for the ItemTemplate is the `PickerItemDetails` class. Therefore, we recommend specifying the data type for the DataTemplate using x:DataType to ensure the bindings are resolved correctly.

Example:

 

<Grid>

 

        <Grid.Resources>

            <local:DataTModelConverter x:Key="converter" />

 

            <DataTemplate x:Key="customView" x:DataType="picker:PickerItemDetails">

                <StackLayout BackgroundColor="Yellow">

                    <Label HorizontalTextAlignment="Center"

                           VerticalTextAlignment="Center"

                           TextColor="Red"

                           Text="{Binding Data,Converter={StaticResource converter} }" />

                </StackLayout>

            </DataTemplate>

        </Grid.Resources>

 

        <picker:SfPicker x:Name="Picker"

                         ItemTemplate="{StaticResource customView}">

        </picker:SfPicker>

 

</Grid>

 

We have updated your sample by adding x:DataType and attached the modified version for your review. Kindly check the attached sample and let us know if the issue persists or if you need any further clarification.

Hello Vidyalakshmi,

I notice that the documentation still hasn't been updated 😉

Please remember to do so, as it's incomplete as it stands.
