How do I refresh db and app at same time? - asp.net

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.

Answer 1

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.
You can find other connection strings here:

Happy coding Kenny!

Just call your stored procedure from application before you call gridView1.DataBind()
This is how you call a stored procedure from your code:
public object ExecuteStoredProcedureAsValue(SqlConnection conn,
string storedProcName,
List<SqlParameter> parameters)
{
using (var command = new SqlCommand(storedProcName, conn)) {
command.CommandType = CommandType.StoredProcedure;
if (parameters != null)
parameters.ForEach(p => command.Add(param));
object result = null;
using (var reader = command.ExecuteReader()) {
while (reader.Read())
{
result = reader[0];
break;
}
}
return result;
}
}
Take notice that "conn" is SqlConnection object. You should initialize and open sql connection before calling this code.
