Hi egirardi,

I tested this scenario here in the upcoming 6.4.0 Release d, and was not able to see any problem. The DragDrop event of the UserControl fires fine.

Two things come to mind, and you seem to already have covered the first one. You need to set the UserControl1 as a member of the ListBox.DragTargets. Second, having UserControl1 as the DragTargets or the ListBox would mean that you could only drop a ListBox item on an "empty space" within the UserControl1. If you drop it on, say, a TextBox within UserControl1, that control is not a member of ListBox.DragTargets, unless you explicitly set it, so you would get no DragDrop event fired. In addition, in that case, the DragDrop event of the TextBox should fire.

Hope this explains,

Hi egirardi,

I kind of suspected that was the case, that you wanted some internal controls of the UserControl to be the actual targets.

There are zillion ways to make this work. One of them might be to add a function to your UserControl, and have that function or readonly property return an array of Component of the internal controls that you do want to serve as dragtargets inside the UserControl. Let's say you have a UserControl with a TextBox1 and Button1 that you want for this purpose. Your C# readonly property might then look like this:

        public Gizmox.WebGUI.Forms.Component[] getInternalDragTargets

        {

            get

            {

                Gizmox.WebGUI.Forms.Component[] objTargets = 

                    new Gizmox.WebGUI.Forms.Component[] 

                    {   this.button1,

                        this.textBox1 };

                // Make sure all the internal controls allow drop

                foreach (Gizmox.WebGUI.Forms.Component ctrl in objTargets) {

                    ((Control) ctrl).AllowDrop = true ;

                }

                // You also must make sure the internal controls do have a registered

                // DragDrop event handler and they know what to do with "their" drops.

                return objTargets;

            }

        }

Then in your ListBox, you need to set ListBox1.DragTargets = UserControl1.getInternalDragTargets and you should have this working as expected.

Hope this helps,
