Hi,

What is dr1 in Find function? if you have to call the sub function while another datareader is open then in connection string you have to enable MARS(MultipleActiveResultSets).

e.g

C#

string connectionString = "Data Source=MSSQL1;" +
    "Initial Catalog=AdventureWorks;Integrated Security=SSPI;" +
    "MultipleActiveResultSets=True"
