I have a big query that takes time to execute.
When I execute it in another thread I have a problem .

Let us see
// pseudocode
  Thread startSql=new Thread(new ThreadStart(RunSql));
  public void RunSql()
//where runselect return table
When I try to run thread it throw exception that I cannot access the datagridview through another thread.

How can I solve this?

You can't access controls except from the thread on which they were created (the UI thread).
In order to do it you must use P/Invoke:
Invoke(new MethodInvoker(delegate { DataGridView1.datasource=Connection.runselect(sqlStatment); }));
