Drag auto fill like Excel in Multicolumn Listbox

[miguelc]

I'm trying to implement a drag auto-fill feature (like Excel's) on a multicolumn listbox (where you click and hold on the bottom right corner of a cell, drag down, then release to fill in all covered cells with the first cell). I've worked out almsot everything except when the drag goes to cells below the visible. In this case I want it to scroll the multicolumn listbox down until the user releases the mouse button (again, like Excel).  Any suggestions on how to accomplish this?

Hi Michael,

Assuming you're implementing this feature using invoke/property node, you can try setting the Top Left Visible Cell, Number of Columns, and Number of Rows property node to programmatically change the view of the control.
