// If your query needs more than the default 30 seconds,
// you might want to set the CommandTimeout higher.
// To do that you'll change it after you instantiated the DataAdapter on the SelectCommand
// property of that instance, like so:
private void FillInDataGrid(string SQLstring)
{
string cn = ConfigurationManager.ConnectionStrings["Scratchpad"].ConnectionString; //hier wordt de databasestring opgehaald
DataSet ds = new DataSet();
// dispose objects that implement IDisposable
using(SqlConnection myConnection = new SqlConnection(cn))
{
SqlDataAdapter dataadapter = new SqlDataAdapter(SQLstring, myConnection);
// set the CommandTimeout
dataadapter.SelectCommand.CommandTimeout = 60; // seconds
myConnection.Open();
dataadapter.Fill(ds, "Authors_table");
}
dataGridView1.DataSource = ds;
dataGridView1.DataMember = "Authors_table";
}
// The other option: is to address your query. In Sql Server you can analyze
// the execution plan. I bet there is a full-table scan in it.
// You might experiment with adding an index on one or two columns in your [old]
// and [new] table. Keep in mind that adding indexes comes at the cost of higher execution
// times for inserts and updates and space requirements.
