(ChartSeries collection in chart.Series){
foreach (ChartSeriesItem item in collection.Items
{
item.ActiveRegion.Click += new RegionClickEventHandler(ActiveRegion_Click);
}
}

protected void ActiveRegion_Click(object sender)
{
ChartSeriesItem item = (ChartSeriesItem)sender;

item.ActiveRegion.Tooltip = item.Parent.Name;

//MessageBox.Show(item.Parent.Name);
}

error:Error 212 No overload for 'ActiveRegion_Click' matches delegate 'Telerik.Charting.RegionClickEventHandler' 

In my solution I had RadControls 2007 and I can drag an item from a RadList box, to a RadTextbox

After the upgrade to RadControls 2008 Q2 – the behaviour is a bit funny...

If I use the MouseDown  event

private void lstAlertTokens_MouseEnter(object sender, MouseEventArgs e)

        {

            if (lstAlertTokens.SelectedIndex >= 0)

            {

                string text = lstAlertTokens.Text;

                lstAlertTokens.DoDragDrop(text, DragDropEffects.Copy);

            }

        }

 The Drag and drops works, but when I click on items in the list, they are not selected (highlighted), I must use the up/down keyboard keys to first select the item I want, before I drag and drop it.

If I use the mouseUp event

 The item selection works now (gets highlighted) when I click the mouse , but the DragDrop effect icon is missing.. So the drag and drop works, but you don’t see the  DragDropEffects.Copy effect.

Any ideas?
