Disable Fetch records on Load

[jeanmarc]

Hi,

I have one main form M1 with 2 subform S1 & S2.

M1 is parent of S1 and S1 & S2 are linked via the filter property.

However, if no record are available in S1, S2 is still queried with all records.

How can i disable fetching all records on load and query only if S1.controlname is not null.

Thanks
JM
