Data (view or table) added to the FlexPivotPage control can be visualized by creating views. You can create summarized views by dragging data fields into various lists at runtime as illustrated in Creating Different Views at Runtime topic. To create a default view that appears automatically when your FlexPivot application runs, you need to perform some design-time settings and add set the ViewDefinition property in code.

Complete the following steps to create an application that displays a default view with ProductName in the Rows list, Country in the Columns list, and ExtendedPrice in the Values list.

1. Create a new Windows Forms Application project in Visual Studio.
2. Add the C1FlexPivotPage control to your project and bind it to Invoices view of the c1NWind data source file as illustrated in Binding FlexPivot to Data Source topic.
3. In Solution Explorer, right-click your project and click Properties to open Project designer.
4. In the Project Design, click Settings option.
5. Create a new setting and name it, for example, DefaultView.

   

          
6. Switch to code view and add the following code in Form1_Load event to initialize the default view and set the data fields.
   • Visual Basic
   • C#

   • Visual Basic

   Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
       ' modify the connection string to make it work for the current user on this machine
       Me.InvoicesTableAdapter.Connection.ConnectionString = GetConnectionString()
   
       'loads data into the table adapter
       Me.InvoicesTableAdapter.Fill(Me.C1NWindDataSet.Invoices)
   
       ' show default view:
       ' this assumes an application setting of type string called "DefaultView"
       Dim view = My.Settings.DefaultView
       If Not String.IsNullOrEmpty(view) Then
           c1FlexPivotPage1.ViewDefinition = view
       Else
           ' build default view now
           Dim fp = c1FlexPivotPage1.FlexPivotEngine
           fp.BeginUpdate()
           fp.RowFields.Add("ProductName")
           fp.ColumnFields.Add("Country")
           fp.ValueFields.Add("ExtendedPrice")
           fp.EndUpdate()
       End If
   End Sub
   

   • C#

   private void Form1_Load(object sender, EventArgs e)
   {
       //modify the connection string to make it work for the current user on this machine
       this.invoicesTableAdapter.Connection.ConnectionString = GetConnectionString();
       
       //loads data into the table adapter
       this.invoicesTableAdapter.Fill(this.c1NWindDataSet.Invoices);
   
       // show default view:
       // this assumes an application setting of type string called "DefaultView"
       var view = Properties.Settings.Default.DefaultView;
       if(!string.IsNullOrEmpty(view))
       {
           c1FlexPivotPage1.ViewDefinition = view;
       }
       else
       {
           // build default view
           var fp = c1FlexPivotPage1.FlexPivotEngine;
           fp.BeginUpdate();
           fp.RowFields.Add("ProductName");
           fp.ColumnFields.Add("Country");
           fp.ValueFields.Add("ExtendedPrice");
           fp.EndUpdate();
       }
   
   }
   

7. Initialize a standard connection string to the database file being used.
   • Visual Basic
   • C#

   • Visual Basic

   'initializing the connection string
   Private Shared Function GetConnectionString() As String
       Dim path As String = Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "\ComponentOne Samples\Common"
       Dim conn As String = "provider=microsoft.jet.oledb.4.0;data source={0}\c1nwind.mdb;"
       Return String.Format(conn, path)
   End Function
   

   • C#

   //initializing the connection string
   static string GetConnectionString()
   {
       string path = Environment.GetFolderPath(Environment.SpecialFolder.Personal) + @"\ComponentOne Samples\Common";
       string conn = @"provider=microsoft.jet.oledb.4.0;data source={0}\c1nwind.mdb;";
       return string.Format(conn, path);
   }
   

8. Press F5 to run the application. The default view gets displayed with ProductName appearing in the Rows list, Country in the Columns list, and ExtendedPrice in the Values list.
