Hi, I'm fairly new to Flex and I'd appreciate your help. I'm trying the following:
I have a DataGrid with 28 columns representing a calendar of some sort with "dropEnabled" set to "true" and all the drop events defined (dragEnter, dragExit, dragDrop). This part works very well. The leftmost column, which is locked ("lockedColumnCount=1"), represents resources and the other columns have a count of defects associated to each resource at a specific date. I also have a List with "dragEnabled" set to "true". This list contains a list of defect objects which are different than what is displayed in the DataGrid. When the user clicks on a number of defects displayed in the DataGrid for a resource, the list of defects is displayed in the list. My goal is to be able to drag a defect displayed in the list to a new resource / date location in the DataGrid and update the counts displayed. So far, I'm able to get the row (through "calculateDropIndex") but I am unable to figure out the column. I tried calculating the column from the mouse position (x) by adding the columns widths as I iterate through the columns this way: =========================================================== private function calculateDropColumn(event:DragEvent):int { var colWidth:int = 0; var mouseXpos:int = event.localX; var dropTarget:DataGrid = DataGrid(event.currentTarget); for (var i:int = 0; i < dropTarget.columns.length; i++) { if (mouseXpos >= colWidth && mouseXpos <= (colWidth + dropTarget.columns[i].width)) { return i; } colWidth += dropTarget.columns[i].width; } return -1; } =========================================================== It works fine until I start scrolling the columns to the right... I saw that the DataGrid maintains an Array of "visibleColumns" and "visibleLockedColumns" internally through the debugger, but they are not exposed (mx_internal namespace). Anybody has a better way? Am I using the correct component for this kind of thing? Is there a way to determine the "visibleColumns" another way? Thanks for your help as I am at a lost... Marc
