Add button in Row Header

Mee A posted over 3 years ago

Hi All,

I got requirement in displaying icon in row header near to the row selection indicator (attached screenshot) based on some condition.

Is there any possibility to add a button in the row header so that user can interact with it.

Please share me any example if possible.

Thank you,

Sundaram.

Hello and thank you for contacting Infragistics.

There isn't anything out of the box to achieve this without using something like a creation/draw filter customize the control.

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.
