Question

We have a stored proc that grabs that data from a table, let’s call it table1 from one db1 and populates a table, called table2 in db2.

We scheduled this stored proc to perform this function like every 5 minutes. This works fine.

Given that users mostly leave their apps while performing other administrative functions, we have created a refresh button that refreshes the GridView upon clicking the button.

Protected Sub Refresh_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Refresh.Click
    ' Clean up text to return the GridView to it's default state
      strSearch.Text = ""
      SearchString = ""
      gridView1.DataBind()
End Sub

We would like to both click this refresh button to both to have the stored procedure update table2 and at same time, refresh the GridView.

I know that gridview1.Databind() refreshes the GridView with latest data from table2 but how do I ensure that table2 is first updated with data from table1 using the stored proc before refreshing the GridView.

Kenny I have prepared complete code in vb for you, take a look:

Private Sub CallRefresh()
     Dim connectionString As String = "Initial Catalog=myDataBase;data source=myServer;Integrated Security=SSPI;"
     Dim storedProcName As String = "ActivateServerTask"
     Dim conn As SqlConnection = New SqlConnection(connectionString)
     conn.Open()
     Dim command As SqlCommand = New SqlCommand(storedProcName, conn)
     command.CommandType = CommandType.StoredProcedure
     command.Parameters.Add(New SqlParameter("@taskId", 1))
     command.ExecuteNonQuery()
     command.Dispose()
     conn.Close()
     conn.Dispose()
 End Sub


 Protected Sub Refresh_Click(ByVal sender As Object, ByVal e As EventArgs) Handles     Refresh.Click       
      CallRefresh()
      gridView1.DataBind()       
 End Sub 

CallRefresh opens connection, executes “ActivateServerTask” stored procedure with “taskId” parameter and finally closes connection…
Take notice I am using connection to sql with integrated security.

Happy coding Kenny!
