ASP.NET Increase SQL Timeout on Gridview Databind

Question

Getting the following sql timeout on a page System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

GridView1.DataBind();

While I know I need to review the actual Stored Procedure used, can someone point me to a quick fix to increase the timeout on the databind.

Below is my datasource

asp:SqlDataSource ID="srcReportList" runat="server" ConnectionString="<%$ ConnectionStrings:DBConnectionString %>" SelectCommand="spGetStoreTrainingSummary" SelectCommandType="StoredProcedure">
