I have 8 ClientDataSets in DataModule and all them are relations with the master ClientDataset, the master ClientDataSet has 135 records and the others has 5 record each one, but when a try to Activate the Master ClientDataSet it's too slow to open it and it opens all ClientDataSet childs together. Is there a solution to eliminate this long time to open all ClientDataSet's, or I can just Open the Master ClientDataSet and the childs stayed closed ??? Thanks in advance Adriano Back to top Jackson Gomes - Tools&Com Guest Posted: Thu Sep 07, 2006 1:34 am    Post subject: Re: Too slow to open the ClientDataSet Quote: together.
