Hi,

We got the solution. We changed our code in DataAccess Layer.Correct code is below.

Thanks for your help:)

public void AddParameter(DbCommand cmd, Database db)

{

if (Parameters != null)

{

foreach (DictionaryEntry param in Parameters)

{

if (param.Value.GetType() == typeof(string))

{

db.AddInParameter(cmd, param.Key.ToString(), DbType.String, param.Value);

}

if (param.Value.GetType() == typeof(int))

{

db.AddInParameter(cmd, param.Key.ToString(), DbType.Int32, param.Value);

}

if (param.Value.GetType() == typeof(decimal))

{

db.AddInParameter(cmd, param.Key.ToString(), DbType.Decimal, param.Value);

}

}

}

}
