Hi Michael,

Thanks for your response.

After investigating further me too thought to use creation/draw filter.

I have tried with creation filter as below.

public class RowHeaderIconIndicatorsCreationFilter : IUIElementCreationFilter
    {
        public RowHeaderIconIndicatorsCreationFilter()
        {

        }
        public void AfterCreateChildElements(UIElement parent)
        {
            if (parent is RowSelectorUIElement)
            {
                RowSelectorUIElement header =
                    (RowSelectorUIElement)parent;
                bool isSelected = ((parent.Parent as RowUIElement).Row.ListObject as EmployeeData).IsSelected;
                if (!isSelected)
                    return;
                Infragistics.Win.ButtonUIElement button = new ButtonUIElement(parent);
                Rectangle parentRect = parent.RectInsideBorders;
                button.Rect = new Rectangle(parentRect.X + parentRect.Width - 10, parentRect.Y, 10, 10);
                button.Text = "\u0007";
                button.TextHAlign = HAlign.Center;
                button.TextVAlign = VAlign.Middle;
                button.ElementClick += new UIElementEventHandler(button_ElementClick);
                parent.ChildElements.Add(button);
            }
        }
        void button_ElementClick(object sender, UIElementEventArgs e)
        {
            MessageBox.Show("Button clicked");
        }
        public bool BeforeCreateChildElements(UIElement parent)
        {
            return false;
        }
    }

it is working fine, but i have requirement to open popup when user double click on the button UI element

I didn't see any double click event . is it possible to achieve it?

How we can use draw filter for my requirement?.

Thanks 

Sundaram.

I would use the DoubleClick event on the control. 

You could check grid.DisplayLayout.UIElement.LastElementEntered and if that element (or more likely one of it ancestors) is a ButtonUIElement, you could then use GetContext to get the UltraGridCell and respond. 

Although, personally, I think it's a little weird to show a context menu on a double-click. It's standard Windows behavior to show Context menu on a right-click using MouseUp.
