Dear Friends,
There are 2 form (form1,form2) and 2 dialogbox (dialogbox1,diologbox2) in my application.
When application start at that time form 1 loaded, on form 1 when button-1 click, form2(as mdi parent) and dialogbox-1 (with textbox-1 and button-1 as mdichild) show. when button-1 on dialogbox-1 click dialog-2 (with textbox-1) show.
On close event of dialogbox-2 or activate event of dialogbox-1 the data on textbox-1 of dialog-2 will send to textbox-1 of dialogbox-1 but this event does not fired.
