Hi..
I got problems where I'm going to put addhandler to enable drop and drop between flowlayoutpanels..
In my form1.. I have docked a flowlayoutpanel.. for testing purposes.. I have a button in my flowlayoutpanel1, which is named "Add group", When I press Add Group, It calls a UserControl which I created.
In my UserControl which is named "Card" A groupbox is docked into the usercontrol and then a flowlayoutpanel is docked into the groupbox, and 1 panel is in my flowlayoutpanel which is named "Add Card", the panel is actually a click button and uses an "Component" which is named "cardPanel" everytime I click the panel.
So back in my form 1, I would press "Add Group" it would call the UserControl which is "Card" and within the card there is the the click button which is actually a "panel" , everytime I click the panel.. it creates a panel inside the flowlayoutpanel of the "UserControl (Card)"

The Problem is.. I don't know how to properly put the dragenter, dragdrop and mousedown handler evertime I add a group, Sample1 should be draggable to Sample2, and if I add another group, it should also be draggable in Card3.. and its added controls can also be draggable to card1 and card2
