Answer 2

Okay, I found a solution to my problem: the textbox on the form was some content of the currently selected row of a table. Now I added an event to this form for changes of the row-selection ( Form_Current ) which calls a method which manually sets the textbox value directly via a column of the selected table-row like this:

[Forms]![MainForm]![SubForm].[Form]![SubSubForm].[Form].SomeTextBox.SetFocus
[Forms]![MainForm]![SubForm].[Form]![SubSubForm].[Form].SomeTextBox = [Forms]![MainForm]![SubForm].[Form]![SubSubForm].[Form]![SubSubFormTable].[Form]![NeededColumn]

When you link the subform inside Form the filter will work automatically just add the field belong to the child field(ChiledTable). if this not what you mean provide sample of DB.
