Toolbox is empty

[Gregor]

Hi,

I have an issue with toolbox for existing Xamarin project. When I open View the toolbox is empty with a message: "There is no Syncfusion control. Open the appropriate .xaml file from the Xamarin shared project". The same message appears in case I create new view. But if I create new project all controls are there in the toolbox. I assume there is an issue with my project or is there something else?

Thanks!

[Gregor]

I did a few things and now error is gone and toolbox has all the elements. Do not know what helped but I did an update of Xamarin.Forms NuGet to 5.0.0.2545, restarted VS and computer, and cleared up an errors in my project (one modal view and view did not have correct namespaces).

I am having the exact same issue. What should I do?

I have been busy on a project for a few months and now want to use SyncFusion controls to make it look better. The documentation I have found so far only explain how to create a new project but not how to add it to an existing one.

I have generated my license key and added it to the App.cs file as instructed after downloading a whole bunch of NuGet packages for MAUI. 

Now.... now what do I do? I am stuck at this point. Please help.

Thanks

Hi Ryunosuke Jansen,

Query: The documentation I have found so far only explain how to create a new project but not how to add it to an existing one.

Based on your query, we understand you want to add Syncfusion controls to an existing project. The process for adding Syncfusion controls to an existing project is the same as adding them to a new project. Below are the steps to guide you through the process.

Adding Syncfusion Controls to Your Existing Project

1. Install the Syncfusion NuGet Package:

For each control you want to use, install the corresponding Syncfusion NuGet package. For example, to use the SfTabView, install the Syncfusion.Maui.TabView package.

2. Register the Syncfusion Handler in MauiProgram.cs:

After installing the package, you must register the Syncfusion handler in your MauiProgram.cs file. This step is crucial for initializing Syncfusion controls within your application.

Here's how you can do it:

//MauiProgram.cs

 

using Syncfusion.Maui.Core.Hosting;

…

public static class MauiProgram

{

   

    public static MauiApp CreateMauiApp()

    {

        var builder = MauiApp.CreateBuilder();

        builder

            .UseMauiApp<App>()

            .ConfigureSyncfusionCore();

            .ConfigureFonts(fonts =>

            {

                …

            })

#if DEBUG

        builder.Logging.AddDebug();

#endif

 

        return builder.Build();

    }

}

3. Utilize the Controls in Your XAML Pages:

In your existing ContentPage or ContentView, include the namespace for the Syncfusion control you want to use. Here’s an example of adding SfTabView:

<ContentPage …

xmlns:tabview="clr-namespace:Syncfusion.Maui.TabView;assembly=Syncfusion.Maui.TabView">

    <Grid>

        <tabview:SfTabView x:Name="tabView" HeightRequest="200" WidthRequest="300">

            <tabview:SfTabView.Items>

                <tabview:SfTabItem Header="Call">

                    <tabview:SfTabItem.Content>

                        <Grid BackgroundColor="Red" />

                    </tabview:SfTabItem.Content>

                </tabview:SfTabItem>

                <tabview:SfTabItem Header="Favorites">

                    <tabview:SfTabItem.Content>

                        <Grid BackgroundColor="Green"/>

                    </tabview:SfTabItem.Content>

                </tabview:SfTabItem>

                <tabview:SfTabItem Header="Contacts">

                    <tabview:SfTabItem.Content>

                        <Grid BackgroundColor="Blue"/>

                    </tabview:SfTabItem.Content>

                </tabview:SfTabItem>

            </tabview:SfTabView.Items>

        </tabview:SfTabView>

    </Grid>

</ContentPage>

That was an incredibly painless process! Thank you! 

Having to install 40+ individual NuGet packages and having to add up to 40+ extra namespaces (per ContentPage or per ContentView) seemed like a real bother. Why not just have all 40+ controls in the same namespace (called SfControls, maybe?) That sounds like it makes a lot more sense and will cut down on a lot of typing

... but once my Toolbox populated with the controls and I see you automatically add the namespaces for me when I use a control... yeah, this system of yours is just superb! Once it is setup it's quite awesome!

Thanks for that detailed reply. Very much appreciated
