IDataSourceWizardConnectionStringsStorage Interface

When implemented by a class, represents a storage of data connections used in the Dashboard Data Source Wizard.

Namespace: DevExpress.DashboardWeb

Assembly: DevExpress.Dashboard.v23.2.Web.dll

NuGet Package: DevExpress.Web.Dashboard.Common

Declaration

C#

public interface IDataSourceWizardConnectionStringsStorage :
    IDataSourceWizardConnectionStringsProvider

VB.NET

Public Interface IDataSourceWizardConnectionStringsStorage
    Inherits IDataSourceWizardConnectionStringsProvider

Remarks

The following code snippet shows how to save the created connection strings in the the ASP.NET Core dashboard application.

Implement the IDataSourceWizardConnectionStringsStorage interface to use it as a place where to save the newly created connection strings:

using DevExpress.DashboardWeb;

public class ConnectionStringProvider: IDataSourceWizardConnectionStringsStorage {
    readonly Dictionary<string, DataConnectionParametersBase> storage = new Dictionary<string, DataConnectionParametersBase>();
    public Dictionary<string, string> GetConnectionDescriptions() {        
        return storage.ToDictionary(p=>p.Key, p=>p.Key);
    }

    public DataConnectionParametersBase GetDataConnectionParameters(string name) {
        return storage[name];
    }

    public void SaveDataConnectionParameters(string name, DataConnectionParametersBase connectionParameters, bool    saveCredentials) {
        storage[name] = connectionParameters;
    }
}

Use the created class instance as the SetConnectionStringsProvider‘s parameter so users can reuse the connections and create new JSON data sources at runtime:

using DevExpress.DashboardWeb;
using DevExpress.DataAccess.Web;
using DevExpress.DataAccess.ConnectionParameters;
using System.Linq;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDevExpressControls();
builder.Services.AddScoped<DashboardConfigurator>((IServiceProvider serviceProvider) => {
    DashboardConfigurator configurator = new DashboardConfigurator();
    configurator.SetConnectionStringsProvider(new ConnectionStringProvider());
    // ...
    return configurator;
});

var app = builder.Build();
