This section provides overview for working with Essential SfNumericUpDown for Xamarin.Forms. You can walk through the entire process of creating a SfNumericUpDown.
After installing Essential Studio for Xamarin, you can find all the required assemblies in the installation folders, {Syncfusion Essential Studio Installed location} \Essential Studio{Version #}\Xamarin\lib.
You can add SfNumericUpDown reference using one of the following methods:
Syncfusion Xamarin components are available in nuget.org. To add SfNumericUpDown to your project, open the NuGet package manager in Visual Studio, search for Syncfusion.Xamarin.SfNumericUpDown, and then install it.
Syncfusion also provides Xamarin Toolbox. Using this toolbox, you can drag the SfNumericUpDown control to the XAML page. It will automatically install the required NuGet packages and add the namespace to the page. To install Syncfusion Xamarin Toolbox, refer to Toolbox.
If you prefer to manually reference the assemblies instead referencing from NuGet, add the following assemblies in respective projects.
To launch SfNumericUpDown in iOS, need to create an instance of SfNumericUpDownRenderer in FinishedLaunching overridden method of AppDelegate class in iOS Project as shown below.
[C#]
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
SfNumericUpDownRenderer.Init();
LoadApplication(new App());
return base.FinishedLaunching(app, options);
}
The SfNumericUpDown control can be configured entirely in C# code or by using the XAML markup. The following steps explain how to create a SfNumericUpDown and configure its elements.
- Adding namespace for the added assemblies.
[XAML]
<xmlns:numeric="clr-namespace:Syncfusion.SfNumericUpDown.XForms;assembly=Syncfusion.SfNumericUpDown.XForms"/>
[C#]
using Syncfusion.SfNumericUpDown.XForms;
- Now add the SfNumericUpDown control with a required optimal name by using the included namespace.
[XAML]
<numeric:SfNumericUpDown/>
[C#]
SfNumericUpDown numericUpDown=new SfNumericUpDown();
this.Content = numericUpDown;
The SfNumericUpDown control display value can be set using the Value property.
[XAML]
<numeric:SfNumericUpDown Value="5"/>
[C#]
SfNumericUpDown numericUpDown=new SfNumericUpDown();
numericUpDown.Value= 5;
this.Content = numericUpDown;
To run this application, you need to first clone the Getting-Started-SfNumericUpDown-in-Xamarin-iOS repository and then open it in Visual Studio 2022. Now, simply build and run your project to view the output.
If you are facing path too long exception when building this example project, close Visual Studio and rename the repository to short and build the project.
