After some checking through previous emails and manual I found and edited some
code:
cbosubject is a combo box with no datasource attached. The grid field
datasource is different from that of the form. The question is: I expected
the function hk_thisform.get_pyvisible("cbosubject").value() to return the
listcolumn value, not the viewcolumn value. How can I get the selected
listcolumn value? The filter works fine, except that I cannot use a
reference to another table.
filtervalue=hk_thisform.get_pyvisible("cbosubject").value()
hk_this.show_warningmessage(filtervalue)
gridact=hk_thisform.get_pyvisible("gridtblact")
filterstring ="actsubjectid = " + filtervalue
hk_this.show_warningmessage(filterstring)
gridact.datasource().disable()
gridact.datasource().set_temporaryfilter(filterstring)
gridact.datasource().set_use_temporaryfilter(True)
gridact.datasource().enable()
