Thanks for that.

Switching off the style library does indeed stop hot tracking. I was using just one of the example templates styles which seems to bring on hot tracking and I couldn't work out how to stop it in the the App Style.

I also wanted the row selection to switch off i.e, just for a selected cell to be highlighted. I did this by editing the style library so that selected row appearance was the same as normal, unseleced row appearance which I think was a bit of a hack.

In fact, what I want is something that selects like Excel, so that I can work at cell level. No hot tracking of rows or cells and when a cell is clicked only that cell is highlighed and not its entire row.

 Thanks.

 All of this should be acheivable, but since I don't know what isl you are using, I can't tell you what in the isl is causing these settings. There are any number of roles that could be causing the grid to HotTrack. What I would do is open up the isl in AppStylist and go to the grid tab. Mouse over a grid row and look at the list of roles that come up in the tooltip. Examine each role listed and see which one has settings applied to it. Specifically, check for the HotTracking state on the tabs at the bottom. 

Is there a way to stop the hot tracking by code?

I like the hot tracking but some grids are read-only where hot tracking does not make too much sense. In those cases I would like to something like this:

Grid.hottracking = false

Grid.ActiveRow = none

Hi,

There's no switch for turning HotTracking on and off. The grid will HotTrack the rows if there is a HotTrackAppearance defined, either in the code or in AppStylist.

If it's defined in the code, then you can simply reset it to turn it off.

Something like this:

this.ultraGrid1.DisplayLayout.Override.ResetHotTrackRowAppearance

If it's on in AppStylist, then you have to turn it off within your isl file. If you have some grids that need HotTracking and others that do not, then what you could do is reset the HotTracking state of the UltraGridRow UIRole in the default StyleSet in your isl file. Then you add a new StyleSet and set it to be BasedOn the default StyleSet so it picks up all of it's properties. Then you add HotTracking to the new StyleSet.

Then, all you have to do is turn on HotTracking for the grids you want in your application by setting the StyleSetName on those grids to the name of the new StyleSet you created.

my UltraGrid Hottrack settings are in the ISL file.

In the ISL file my header appearance of the grid is set to Halignment: is Left. (normal state)

In the ISL file my header appearance of the grid is also set with  hottracking state  -->  HAlignment is left.

I have written some code, to turn the HAlignment if it is a currency column  to the right., for both cellappearance en headerappearence, something like this:

If CInt(row("IsBedrag")) <> 0 Then

With mvarFlexGrid

.DisplayLayout.Bands(0).Columns(i).CellAppearance.TextHAlign = Infragistics.Win.HAlign.Right

.DisplayLayout.Bands(0).Columns(i).Header.Appearance.TextHAlign = HAlign.Right

This does work. the problem i have is that the text of the header is aligned right but if i hottrack it with the mouse, the text jumps to left, because the hottracking alignment in isl is set to left.

With the above lines of code, i overruled apparentlyI the alignment of the normal state, i also want to overrule the alignment of the hottracked state.

So i added to following lines, but is still doesn't work..

.DisplayLayout.Override.HotTrackHeaderAppearance.TextHAlign = HAlign.Right

How can it be, i am able to overrule the normal state alignment, but not the hottracked state alignment?
