Thanks Georgi. I'm still having trouble having it work exactly how we'd like.

Please see attached solution with modified version of your sample to better illustrate our use case.

What we'd like to have is

• A textbox in the group area above each column.
• If the user types a number into this textbox, we want all cells in that column under that group to increment by that amount.
• For example, if in the first group (EUR) I go to the textbox above the Coupon column, and type "1.0", I want all the numbers in that group and column to increment (i.e. 3, 17, 31, 45 in this case becomes 4, 18, 32, 46).

I hope very much you are able to help us in this scenario. So far I'm unable to get the textbox to appear in the right position and repeat above each column.

Thank you.

• Is there a way to modify the demo to include the control only in group headers?

 - Yes. You could extend the IF condition in the CreationFilter. For example:

public void AfterCreateChildElements(UIElement parent)
{
    HeaderUIElement El = parent as HeaderUIElement;
    if (El != null && El.Header.Group != null && El.Header.Column == null)
    {
        ButtonUIElement newButton = new ButtonUIElement(El);
        newButton.Text = "X";
        newButton.Rect = new Rectangle(El.Rect.X + El.Rect.Width - 20, El.Rect.Y, 18, 18);
        El.ChildElements.Add(newButton);
        newButton.ElementClick += new UIElementEventHandler(newButton_ElementClick);
    }
}

I`m not sure that I understand well your second point but if you change the control to TextBox, you could access the properties of this control.

Please let me know if you have any questions.

Regards

Thanks Georgi for your sample, it looks promising. A few questions:

• Is there a way to modify the demo to include the control only in group headers?
• If I change the control to a textbox, is there a way to then gain access to contextual information, such as what items are in that group? Something along the lines of a DataContext if this was a WPF control? What we'd like to do is allow the user to put a numeric value in this textbox, which then increments all cells in that group in the same column.
