I'm sure the methods are executing in the correct order. But I'm not sure about it being the same instance. It seems to me it should be the same instance but I'm new to this.
I have a multi-panel form (similating multiple pages). At the bottom of one of the last panels made visible, I have a finish button. In the FinishButton_Click method, the current panel is hidden, another panel is made visible and the data set is built using the data member, dstMaster. Then the user is at the new panel and this panel has a submit button (the finish button is no longer visible). When the user clicks on the submit button, the SubmitButton_Click method tries to access dstMaster and its empty. Seems like it goes away as soon as the code exits the FinishButton_Click method. So, since this is all one form and no other forms are brought up (just a bunch of panels hidden/made visible) then it should be the same instance, right?
