The Dashboard Designer allows you to connect to different types of SQL databases in the Data Source Wizard. You can also use data access API to connect to the database and select data in code.
This tutorial describes how to establish a connection to an SAP SQL Anywhere database and select data.
Important
The appropriate data provider must be installed on the client machine. For information on data providers, refer to the Data Sources article.
To connect to an SAP Sybase SQL Anywhere database in the Dashboard Designer, follow the steps below:
Click the New Data Source button in the Data Source ribbon tab.
On the first page of the invoked Data Source Wizard dialog, specify whether you want to use an existing data connection or create a new data connection.
On the next page, select SAP Sybase SQL Anywhere and click Next.
On the next page, choose the Server type. If you selected Server , the Data Source wizard displays the following connection settings:
Click Next and specify how to select data from the database.
On the final page, you can optionally add query parameters and preview data.
To create a data source that uses a connection to the SAP SQL Anywhere database, create an instance of the DashboardSqlDataSource class and follow the steps below:
Specify connection parameters for the SAP SQL Anywhere database. Create the AsaConnectionParameters class object and specify the following properties:
Create one of the following objects to specify the query:
Add the created DashboardSqlDataSource object to the Dashboard.DataSources collection.
The following code snippet shows how to supply the dashboard with data from the Northwind database deployed on the SAP SQL Anywhere database server:
using DevExpress.DashboardCommon;
using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
// ...
AsaConnectionParameters asaParams = new AsaConnectionParameters();
asaParams.Hostname = "localhost";
asaParams.ServerName = "testserver";
asaParams.DatabaseName = "Northwind";
asaParams.UserName = "Admin";
asaParams.Password = "password";
DashboardSqlDataSource sqlDataSource = new DashboardSqlDataSource("Data Source 1", asaParams);
SelectQuery selectQuery = SelectQueryFluentBuilder
.AddTable("SalesPerson")
.SelectColumns("CategoryName", "Extended Price")
.Build("Query 1");
sqlDataSource.Queries.Add(selectQuery);
sqlDataSource.Fill();
dashboard.DataSources.Add(sqlDataSource);
Imports DevExpress.DashboardCommon
Imports DevExpress.DataAccess.ConnectionParameters
Imports DevExpress.DataAccess.Sql
' ...
Private asaParams As New AsaConnectionParameters()
asaParams.Hostname = "localhost"
asaParams.ServerName = "testserver"
asaParams.DatabaseName = "Northwind"
asaParams.UserName = "Admin"
asaParams.Password = "password"
Dim sqlDataSource As New DashboardSqlDataSource("Data Source 1", asaParams)
Dim query As SelectQuery = SelectQueryFluentBuilder _
.AddTable("SalesPerson") _
.SelectColumns("CategoryName", "Extended Price") _
.Build("Query 1")
sqlDataSource.Queries.Add(selectQuery)
sqlDataSource.Fill()
dashboard.DataSources.Add(sqlDataSource)
