Performance issue due to form datasource active method.

Hi,

I have a form where I have lot of datasources attached to it.In one datasource active method I have lot of code for enabling\disabling, editing\non-editing of controls.(More than 50 controls are being handled here).Due to this the system is taking maximum time to traverse from one record to another.

Could anyone please suggest me the best way to handle this situation.

Thanks in Advance!
