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.

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.

Thank you Georgi, this is very close to what we want. However, a few issues we've noticed:

• When we scroll in this demo using the mouse wheel, we get some screen corruption, as textboxes appear all over the grid in the wrong places. Is there a way to prevent this? Curiously, the problem doesn't appear if we use the scrollbar instead of the mouse wheel.
• Text editors appear also for higher-level groups. For example, next to AAPL we have a text box which does not directly contain datarow items. Is it possible to hide this, and only show it for the lowest leaf-level groups that have datarow children?

Hm.  You are right. I forgot for this scenario.  I didn`t remove the TextEditors. Just modify my Creation fIlter to remove the TextEditors before start draw it again and eveything should works properly

Yes, It is possible. You could extend the IF condition in the Creation Filter and exclude this row (you could check this using property IsGroupByRow and Decription).

Please let me know if you have any questions.

Thanks Georgi, that's helpful - a few more things:

• Could you advise on the best way to modify your Creation fIlter to remove the TextEditors before it starts to draw it again?
• Can we can the textboxes to appear for every column (we noticed the coordinates are currently hardcoded with an 80 pixel offset for just 1 of the columns).

Is there a way to determine if an UltraGridGroupByRow is a leaf-level group by row (i.e. has further no child group by rows). The IsGroupByRow and Description properties don't seem to help in this regard - we're wondering if there's anything else?

 There are many approaches to solve this taks. In the sample I just exclude these rows on depend of the Value. Please take a look in the sample for details

Hi,

Maybe one possible approach could be if you are using the code:

foreach (Control cnt in grid.Controls)
 {
 DependentTextUIElement UI = grid.DisplayLayout.UIElement.ElementFromPoint(cnt.Location) as DependentTextUIElement;
   if (cnt.GetType() == typeof(UltraTextEditor) && UI == null)// && !IsScrol)
   {
    grid.Controls.Remove(cnt);
    }
 }

Please take a look at the modifications in the sample for more details.

Yes. It is possible. Just replace the hardcoded offset with the Cell`s X location from Rect property

Update: we're using this method - let us know if you know of a better way:

GroupByRowDescriptionUIElement groupByRowDescriptionUiElement = parent.Parent as GroupByRowDescriptionUIElement;

UltraGridGroupByRow ultraGridGroupByRow = groupByRowDescriptionUiElement.GroupByRow;

Debug.WriteLine(">> ultraGridGroupByRow.ChildBands.FirstRow: " + ultraGridGroupByRow.ChildBands.FirstRow);

if (ultraGridGroupByRow.ChildBands.FirstRow.GetType() != typeof(UltraGridGroupByRow))
