No forms are not the sequence forms I gave different name to all forms like AdmissionFrm , blockwiseFrm etc
Actuially I have two forms for viewing information and when I select one option from the treeview it opens one form say form blockwiseFrm and when i click other option it opens other form say districtFrm. So when i click districtFrm then i want to see the blockwiseFrm information using Previous button. I make one previous button and store blockwiseFrm in the form object say frm but what is happening is it reloads all data in the blockwise form but i want to see the data which i previously saw there.
Say, you have Populated FirstForm based on some DistrictName/id.. Now, Keep a Global Variable to save that ID, When you load district form, in Formload, check if that ID <> blank/zero, then Re-load the data accordingly...
Other option is not to unload the prev Form, Just Hide it.. :
And when you want to show it again, Me.Show
