## Content



This quick start guides you through the steps of adding the FlexPie control in your Blazor application, adding data to it and displaying the data in the control. In this example, we create a data source for FlexPie by creating list of sales data of automobile companies and bind the list to the FlexPie control to display the data.

## Create a Blazor App

1.  In Visual Studio, select **Create a new project** from the **Get started** pane.
2.  In the **Create a new project** dialog, select **Blazor WebAssembly App**, and click **Next**. Alternatively, you can also create a Blazor Server App. 
	> type=note
	> **Note**: **Blazor Server App** or server-side app can be created using the Blazor Server App template. For more details, see [Blazor Server](/componentone/docs/blazor/online-blazor/blazortypes/blazorserver) topic under Blazor Project Types.
3.  In the **Configure your new project** dialog, provide name of the project you want to create in the **Project name** field and location for the project in the **Location** field. Click **Next**.
4.  In the **Additional information** dialog, select the target framework from the **Framework** dropdown, if required and click **Create**. By default, the selected framework is **.NET 8.0**.<br />A new client-side Blazor app is created.

## Configure References

1.  In the **Solution Explorer**, right click **Dependencies** and select **Manage NuGet Packages**.
2.  In **NuGet Package Manager**, select **nuget.org** as the **Package source**.
3.  Search for **C1.Blazor.Chart** package and click **Install**.
4.  Navigate to the **wwwroot**, open **index.html** file.
5.  Register the client resources by adding the following lines of code to the **\<head>** tag.<br />
    
    ```EXAMPLE
    <link rel="stylesheet" href="/_content/C1.Blazor.Core/styles.css" />
    <link rel="stylesheet" href="/_content/C1.Blazor.Chart/styles.css" />
    ```
    
6.  Add the following code to the **\<body>** tag.
    
    ```html
    <script src="/_content/C1.Blazor.Core/scripts.js"></script>
    <script src="/_content/C1.Blazor.Chart/scripts.js"></script>
    ```
    
7.  Right click on **Pages** folder, click **Add |** **Razor Component** to add a new Razor page and then provide a name, say _FlexPieQuickStart._

## Configure the Data Source

In the code, add a DataSource class to create a list of data for the FlexPie control.

```razor
@code {
    IEnumerable<Palette> palettes = Enum.GetValues(typeof(Palette)).Cast<Palette>().Where((p, x) => p != Palette.Custom);
    Palette? palette = Palette.Standard;
    double[] innerRadiuses = new double[] { 0, 0.25, 0.5, 0.75 };
    double? innerRadius = 0;
    double[] offsets = new double[] { 0, 0.25, 0.5, 0.75 };
    double? offset = 0;
    public class DataSource
    {
        public class SalesData
        {
            public string Name { get; set; }
            public double Value { get; set; }
        }
        public static List<SalesData> GetData()
        {
            var data = new List<SalesData>()
            {
                new SalesData{Name="Maruti", Value=1643467},
                new SalesData{Name="Hyundai", Value=536241},
                new SalesData{Name="Mahindra", Value=248859},
                new SalesData{Name="Tata", Value=210200},
                new SalesData{Name="Honda", Value=170026},
                new SalesData{Name="Toyota", Value=140645},
                new SalesData{Name="Renault", Value=102222},
                new SalesData{Name="Ford", Value=90061},
            };
            return data;
        }
    }
```

## Bind FlexPie to Data

To bind FlexPie to data, set the [ItemsSource](/componentone/api/blazor/online-blazor/dotnet-api/C1.Blazor.Chart/C1.Blazor.Chart.FlexPie.ItemsSource.html) property of [FlexPie](/componentone/api/blazor/online-blazor/dotnet-api/C1.Blazor.Chart/C1.Blazor.Chart.FlexPie.html) class which accepts the collection of items for the FlexPie control. You need to Set [Binding](/componentone/api/blazor/online-blazor/dotnet-api/C1.Blazor.Chart/C1.Blazor.Chart.FlexPie.Binding.html) property to specify a name of numeric property used to calculate the size of slice and set [BindingName](/componentone/api/blazor/online-blazor/dotnet-api/C1.Blazor.Chart/C1.Blazor.Chart.FlexPie.BindingName.html) property to specify a name of property that would be used as the slice name and displayed in chart. legend.

```razor
@using Localization
@using C1.Chart;
@using C1.Blazor.Chart;
@using C1.Blazor.Input;
<FlexPie Class="chart" Palette="palette ?? Palette.Standard" InnerRadius="innerRadius ?? 0" Offset="offset ?? 0"
         HeaderContent="Market Share of Automobile Companies" HeaderStyle="font-size:24px"
         LegendPosition="Position.Bottom"
         BindingName="Name" Binding="Value" ItemsSource="@DataSource.GetData()">
    <Label>
        <PieDataLabel Position="PieLabelPosition.Inside" Content="{p:n1}%" Style="font-size:12px" />
    </Label>
</FlexPie>
```
