But, it is drawn only on left/top/right sides of hot traced cell :) For bottom part - only for bottom cell.

Yeah, that's pretty much what I was saying earlier. Rows only draw some borders sides, not all four. So you would have to use a DrawFilter for this.

SelectionOverlayBorderColor has no effect.

I tried this out and it works fine for me.

Hello,

Tried, but SelectionOverlayBorderColor has no effect. As for changing StyleSet for selection, it would be ok.

I'm now more interested in HotTracking item. This does the trick for backgroud color:

e.Layout.Override.HotTrackRowCellAppearance.BackColor = Color.FromArgb(255, 171, 63); 

And I've achieved border like this:

e.Layout.Override.HotTrackRowAppearance.BorderAlpha = Alpha.Opaque;
e.Layout.Override.HotTrackRowAppearance.BorderColor = Color.FromArgb(211, 206, 185);
e.Layout.Override.RowAppearance.BorderAlpha = Alpha.Transparent;

This way border is drawn only around HotTrack'ed items. 

Hi,

Oh, sure, you could do this with a DrawFilter.

It's a bit tricky, though.

You would need to handle the AfterDrawElement phase of the RowColIntersectionUIElement, I think. You can't do it as part of the drawing of the RowUIElement, because other rows will overlap your row and you will lose part of the borders.

There are also some tricky invalidation issues. When you move the mouse over the dropdown area, individual cells will get incalidated, but not the whole grid, so your border might end up drawing in parts and look odd unless you force an invalidation.

I remember writing some sample code for this in the grid (not the DropDown or Combo) recently.I can't seem to find it, though.

Now that I think about it, maybe you can use the SelectionOverlayBorderColor on the grid's DisplayLayout to get what you want. I'm not sure if it will look exactly like the UltraComboEditor, but it's probably a lot easier than writing the DrawFilter. :)

Hello,

a), c) - understood.

As for b) - if not through Appearance, maybe there is a way with DrawFilters. Like, after drawing background, draw a border. And assign this filter to grid of UltraDropDown.

Hi,

a) We use AppStylist and GridRow role has Selected/Active states with background images. How to reset/override these images, so UltraDropDown would show not image, but ValueList style (orange color with border) for Selected/Active row. Resetting/clearing e.Layout.Override.ActiveRowAppearance, SelectedRowAppearance background on UltraDropDown did not help - or I've reset incorrect properties.

The UltraDropDown and the UltraGrid rows are both the same UIRole. So the only way to do this would be to add a new StyleSet to your isl file and set the StyleSetName on the UltraDropDown to the new StyleSet name in your isl. That way you could style it completely differently than the grid.

b) How to achieve border around hot-tracked UltraDropDown item, as seen in ValueList.

I'm not sure there is any way to do this other than using an ImageBackground with a border in the image.

You could try using the Border style on the GridRow role in your new StyleSet in the isl, but borders in the grid are a little weird. Most objects in the grid only draw one or 2 sides, since otherwise you would end up with double-thick borders between objects.

c) How to properly share code in forum - with tabs, syntax highlight, etc :)

Use a code tag.I can't show you the text here, since it would get turned into tags and hidden. But basically it looks like this, only instead of the squiggly brackets you use square brackets:

{ code }

// my code here

{ /code }
