I have a webgrid control on my page that is using SqlDataSource to connect to an Oracle database.

The connection string to the oracle database is setup in the web.config, as seen below:

<add name="RPW" connectionString="Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.10.50.240)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=STGSAFR)));User Id=expr_master;Password=Frontier_6;" providerName="Oracle.ManagedDataAccess.Client"/>

The SqlDataSource is defined as:

<asp:SqlDataSource ID="sqlRPWReports" runat="server" ConnectionString="<%$ ConnectionStrings:RPW %>" SelectCommand="SELECT * FROM [RPWReportHeader] ORDER BY ReportName" ProviderName="<%$ ConnectionStrings:RPW.ProviderName %>" ></asp:SqlDataSource>

The Webgrid is defined as :

<ISWebGrid:WebGrid ID="WebGrid1" runat="server" DataSourceID="sqlRPWReports" Height="350px" UseDefaultStyle="True" OnInit="WebGrid1_Init" OnButtonClick="WebGrid1_RebindData" Width="100%" DefaultStyleMode="Win7"> <LayoutSettings AllowAddNew="No" ColumnFooters="Yes" AllowDelete="No" AllowColumnMove="Yes" AllowEdit="No" AllowExport="Yes" AllowFilter="No" AllowGrouping="Yes" AllowSelectColumns="Yes" AllowSorting="Yes" EditOnClick="False"> </LayoutSettings> <RootTable DataKeyField="ReportId"> <SortedColumns> </SortedColumns> <Columns> <ISWebGrid:WebGridColumn Caption="Report Id" Visible="false" DataMember="ReportId" Name="ReportId" EditType="NoEdit" Width="150px"> </ISWebGrid:WebGridColumn> <ISWebGrid:WebGridColumn Caption="Report Name" DataMember="ReportName" Name="ReportName" Width="150px"> </ISWebGrid:WebGridColumn> <ISWebGrid:WebGridColumn Caption="Owner" DataMember="Owner" Name="Owner" Width="150px"> </ISWebGrid:WebGridColumn> <ISWebGrid:WebGridColumn Caption="Category" DataMember="Category" Name="Category" Width="150px"> </ISWebGrid:WebGridColumn> </Columns> </RootTable> </ISWebGrid:WebGrid>

When running the page I get the following exception:

chris21 ExpressReports encountered a fatal error causing process to stop - error is : System.ArgumentException: Unable to find the requested .Net Framework Data Provider. It may not be installed. at

Any assistance would be great.

Thanks.
