ADO.NET Provider for Azure Analysis Services

Build 22.0.8462

Using the AASDataSource

The AASDataSource enables you to use a single Web control to connect to Azure Analysis Services and query data. By binding the control to other controls such as the GridView or ListBox, you can display, edit, and save Azure Analysis Services data in an ASP.NET page. You can use the Visual Studio Designer to initialize the control, visually build queries, and bind controls; you can also define SQL commands from page code. The examples below show both approaches and use the GridView control as an example.

To use the AASDataSource, add a reference to System.Data.CData.AAS.Web.dll in your ASP.NET project.

Bind Data Programmatically

The following example shows how to bind the results of a Azure Analysis Services query to an ASP.NET data grid. After registering the assembly for use with the AASDataSource, set the DataSourceID field of the GridView control to the Id of the AASDataSource control:

<%@ Register Assembly="System.Data.CData.AAS.Web" Namespace="System.Data.CData.AAS" TagPrefix="cc1" %>
<cc1:AASDataSource Id="AASDataSource1" runat="server" ConnectionString="URL=asazure://;" SelectCommand="SELECT Country, Education FROM [adventureworks].[Model].Customer WHERE Country = 'Australia' LIMIT 10"></cc1:AASDataSource>
<asp:GridView DataSourceID="AASDataSource1" runat="server"></asp:GridView>

Bind Data Using the Designer

Complete the following steps to use the Designer in Visual Studio to bind the AASDataSource to a GridView control:

  1. Drag a GridView from the Toolbox onto the page.
  2. Click the Smart Tag of the GridView.
  3. Choose the option to create a new data source, which launches a wizard to configure the control.
  4. On the first page, select a connection string from the menu or click New Connection to define a new connection or to save a connection entry in the Web.config file.
  5. On the next page, select the option to define a SQL statement or visually build the query.

When you exit the wizard, the GridView displays the columns of the result set.
