Bind Dynamic Data to Apexcharts Series using ASP.NET and C#: A Step-by-Step Guide

Setting Up the Project

Let’s get started by setting up a new ASP.NET project in Visual Studio. Follow these steps:

1. Create a new ASP.NET Web Application project in Visual Studio.
2. Choose the “Empty” template and click “Create”.
3. In the Solution Explorer, right-click on the project and select “Manage NuGet Packages”.
4. Search for and install the “ApexCharts” package.
5. Create a new C# class library project to handle our data logic.
6. Add the necessary references to the C# class library project.

Creating the Data Logic

In our C# class library project, we’ll create a simple data class to hold our chart data. Let’s create a new class called “ChartData.cs”:

public class ChartData
{
    public string Category { get; set; }
    public double Value { get; set; }
}

Next, we’ll create a data access layer to retrieve our chart data. Let’s create a new class called “ChartDataAccess.cs”:

public class ChartDataAccess
{
    public static List<ChartData> GetChartData()
    {
        // Simulating data retrieval from a database or API
        List<ChartData> chartData = new List<ChartData>
        {
            new ChartData { Category = "A", Value = 100 },
            new ChartData { Category = "B", Value = 200 },
            new ChartData { Category = "C", Value = 300 },
            new ChartData { Category = "D", Value = 400 },
        };
        return chartData;
    }
}

Binding Dynamic Data to Apexcharts Series

Now that we have our data logic in place, let’s move on to binding dynamic data to Apexcharts series. In our ASP.NET project, create a new web form called “Default.aspx” and add the following code:

<%@ Page Language="C#" %>

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/apexcharts"></script>

<div id="chart"></div>

<script>
    var chartData = [];
    $.ajax({
        type: "POST",
        url: "Default.aspx/GetChartData",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (data) {
            chartData = data.d;
            var options = {
                series: [{
                    name: "Series 1",
                    data: chartData.map(function (item) {
                        return item.Value;
                    })
                }],
                chart: {
                    type: "bar"
                },
                xaxis: {
                    categories: chartData.map(function (item) {
                        return item.Category;
                    })
                }
            };

            var chart = new ApexCharts(document.querySelector("#chart"), options);
            chart.render();
        }
    });
</script>

In the above code, we’re using jQuery to make an AJAX call to a server-side method “GetChartData” to retrieve our chart data. We then bind the data to the Apexcharts series using the “map” function to extract the values and categories.

Server-Side Method (GetChartData)

In our ASP.NET project, create a new method called “GetChartData” in the code-behind file “Default.aspx.cs”:

public partial class _Default : Page
{
    [WebMethod]
    public static List<ChartData> GetChartData()
    {
        ChartDataAccess chartDataAccess = new ChartDataAccess();
        return chartDataAccess.GetChartData();
    }
}

In this method, we’re calling our data access layer to retrieve the chart data, which is then serialized and returned as JSON data to the client-side.

Conclusion

And that’s it! We’ve successfully bound dynamic data to Apexcharts series using ASP.NET and C#. By following these steps, you can easily integrate Apexcharts into your ASP.NET applications and create stunning, interactive charts that showcase your data in a meaningful way.
