Dataform not shown on iOS

[oserv Entwickler]

Hi ive Testing the sfdataform. On Android all working fine, but on iOS the dataform is not shown in the app.

I've taken the  SfDataFormRenderer.Init(); to the FinishedLaunching method of the AppDelegate, but nothing changed.

Here's the XAML Iam using

 <data:SfDataForm
                x:Name="dataForm"
                DataObject="{Binding ContactInfo}"
                LabelPosition="Top"
                AutoGeneratingDataFormItem="DataForm_AutoGeneratingDataFormItem"
                VerticalOptions="StartAndExpand"
                >
                <data:SfDataForm.Behaviors>
                    <beh:EventToCommandBehavior EventName="Validating"  Command="{Binding ValidationCommand}" EventArgsConverter="{StaticResource Validator}" />
                </data:SfDataForm.Behaviors>
        </data:SfDataForm>

Hope anybody can help.

Thanks in advance

Hi Andreas, 

 

Thanks for contacting Syncfusion support. 

 

We have checked your query with “DataForm not shown in iOS”. To launch the dataform in iOS, you should call SfDataFormRenderer.Init() in the FinishedLauching overriding method of AppDelegate class after the Xamarin.Forms framework initialization and before the LoadApplicaiton is called. 

 

Please refer the below link: 

https://help.syncfusion.com/xamarin/sfdataform/getting-started#ios 

 

Please refer the code example 

public override bool FinishedLaunching(UIApplication app, NSDictionary options) 

{ 

 … global::Xamarin.Forms.Forms.Init (); 

 SfDataFormRenderer.Init(); 

LoadApplication (new App ()); 

 

… } 

 

We have prepared a sample based on the provided information. Please find the same below, 

Sample: http://www.syncfusion.com/downloads/support/directtrac/general/ze/Event_CommandSample-1487295268.zip 

 

 

Still you are facing the issue, after initialization of DataForm Renderer in the mentioned AppDelegate class, could you please modify the sample or code snippet with replication scenario to reproduce the issue? So that we can analyze on your requirement further and provide you a possible solution. 

 

Regards, 

Srinivasan

I have the same problem. I have a xamarin forms solution with masterdetail navigation template and in android the sfdataform is working fine but in ios the sfdataform is not shown.

I can run your sfdataform example fine in IOS, the only big diferences that I can see with my proyect is the navigation and that i'm usign the latest version of the nugets in my solution.

Now, I can see what is the problem.

In IOS we need the options VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" added to the SfDataForm.

After that, now I can see the SfDataForm in IOS.

Dear Support

In my case this solution does not work.

Is there any Issue known?

[Patrick]

Aha, the parent stacklayout needs the options FillAndExpand, not the dataForm.

Solved in my case.

Hi, I have de same problem and none of the solutions posted here worked for my case. I have to put the HeightRequest manually.

The data form is inside the main Stacklayout in a Xamarin shell application

[SaiGanesh Sakthivel]

Hi Henry,

#Regarding DataForm is not shown inside the Shell in the iOS platform

We suggest you set the HorizontalOptions and VerticalOptions property as FillAndExpand for the StackLayout and Dataform control. Please refer to the following code snippet for your reference.

Code snippet

<ContentPage.Content>

    <StackLayout HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">

        <dataForm:SfDataForm x:Name="dataForm" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" DataObject="{Binding ContactsInfo}"/>

    </StackLayout>

</ContentPage.Content>

Please refer to the tested sample in the following locations.

Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/DataFormGettingStarted2064527142

Please refer to the following UG documentation for your reference,

Please let us know if you have any concerns.
