Hello Pasi,
Thank you for writing.
Indeed OpenEdge has an issue with generic methods and until this gets resolved you will not be able to use the built-in implementation. You can perform the same check this way:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.radGanttView1.MouseDown += RadGanttView1_MouseDown;
}
private void RadGanttView1_MouseDown(object sender, MouseEventArgs e)
{
RadElement el = this.GetElementAtPoint(this.radGanttView1, this.radGanttView1.RootElement, e.Location, null);
}
public RadElement GetElementAtPoint(Control control, RadElement parent, Point point, List<RadElement> foundElements)
{
if (parent.Visibility != ElementVisibility.Visible)
{
return null;
}
ChildrenListOptions childrenFlags = ChildrenListOptions.ZOrdered | ChildrenListOptions.ReverseOrder | ChildrenListOptions.IncludeOnlyVisible;
Rectangle client = control.ClientRectangle;
foreach (RadElement element in parent.GetChildren(childrenFlags))
{
if (element.ElementState != ElementState.Loaded)
{
continue;
}
if (element.HitTest(point))
{
bool addElement = (foundElements != null) && !(element is BorderPrimitive);
if (addElement)
{
foundElements.Add(element);
}
RadElement res = GetElementAtPoint(control, element, point, foundElements);
if (res != null)
{
return res;
}
if (element.ShouldHandleMouseInput)
{
return element;
}
}
}
return null;
}
}
I hope this helps. Please let me know if you need further assistance.
Regards,
Hristo
