My concern with this method is that it will only allow me to show the same buttons in every cell in that column.  I need to control which buttons display at a row level, so I'm looking to put this code in the InitializeRow() event handler. 

I did try the code above though and still didn't see the button show up in the grid on band 0 (I have 5 or 6 bands, but applied the editor only to band 0 just as a test.  I can't see what setting might be causing the buttons to not be visible. 

Hi,

You are correct. Setting the EditorComponent on the column will apply to all of the cells in that column. If you have different buttons in each cell, you need to set the EditorComponent property on the cell, not the column.

The ideal place to do this is the InitializeRow event.

If you are doing this and you are having trouble getting the buttons to display, then the most obvious reason for that is that your column is not able to enter edit mode. The cell must be editable in order to show buttons. If it's an unbound column, then my guess is that you are disabling editing in the entire grid using the AllowUpdate property on the grid. In which case, the solution is to leave AllowUpdate at the default setting and then use the column.CellActivation property to disable each individual column except the button column.

It's a bound column that is empty.  I don't know if that'll affect anything.  I made the grid editable and verified it by going to the cell that I want to show buttons and put it into edit mode, so I know it can be done.  I've got two grids I'm trying to use this on... one is a single band and the other has child bands.  The common feature is that there are column groups.

I'll summarize what I'm doing and maybe you can find the hole in my logic... to keep things simple... I'm doing all my testing in the grid that has only one band and I've added an unbound column that's in the first group.  If I don't add it to a group I can't see it. 

In the IntializeLayout() event of the grid, I have: 
                Dim column As UltraGridColumn = Me.ugMeasures.DisplayLayout.Bands(0).Columns.Add("imagesUnbound")
                column.DataType = GetType(String)
                column.CellAppearance.ImageHAlign = Infragistics.Win.HAlign.Center
                column.CellAppearance.ImageVAlign = Infragistics.Win.VAlign.Middle

In the InitializeRow() event of the grid, I have:
                Dim editor1 As New UltraTextEditor
                Dim button1 As New EditorButton
                button1.Appearance.Image = My.Resources.lock
                editor1.ButtonsLeft.Add(button1)
                e.Row.Cells("imagesUnbound").EditorComponent = editor1

I have a SetupGrid routine that is called when the datasource is set... here are the settings in that function that may have some affect on this situation (all in a With ugMeasures block)
.SyncWithCurrencyManager = False
                    .DisplayLayout.MaxBandDepth = 5
                    .DisplayLayout.Override.HeaderClickAction = HeaderClickAction.Select
                    .DisplayLayout.Override.SelectTypeCol = SelectType.None
                    .DisplayLayout.Override.SelectTypeCell = SelectType.Single
                    .DisplayLayout.Override.AllowRowFiltering = Infragistics.Win.DefaultableBoolean.False
                    .DisplayLayout.CaptionVisible = Infragistics.Win.DefaultableBoolean.False
                    .DisplayLayout.ViewStyleBand = Infragistics.Win.UltraWinGrid.ViewStyleBand.Vertical
                    .DisplayLayout.Override.CellClickAction = Infragistics.Win.UltraWinGrid.CellClickAction.CellSelect
                    .DisplayLayout.Override.SelectTypeRow = SelectType.Single
                    .DisplayLayout.Override.AllowColSizing = AllowColSizing.Synchronized
                    .DisplayLayout.Override.BorderStyleRow = UIElementBorderStyle.Solid
                    .DisplayLayout.Override.BorderStyleCell = UIElementBorderStyle.Solid
                    .DisplayLayout.Override.GroupByColumnsHidden = Infragistics.Win.DefaultableBoolean.True
                    .DisplayLayout.Override.GroupByRowExpansionStyle = Infragistics.Win.UltraWinGrid.GroupByRowExpansionStyle.Disabled
                    .DisplayLayout.Override.RowSizing = Infragistics.Win.UltraWinGrid.RowSizing.Fixed
                    .DisplayLayout.Override.AllowGroupSwapping = Infragistics.Win.UltraWinGrid.AllowGroupSwapping.NotAllowed
                    .DisplayLayout.ColumnChooserEnabled = Infragistics.Win.DefaultableBoolean.True
                    .DisplayLayout.Override.RowSelectors = Infragistics.Win.DefaultableBoolean.True
                    .DisplayLayout.Override.RowSelectorHeaderStyle = RowSelectorHeaderStyle.ColumnChooserButton
                    .DisplayLayout.Override.AllowUpdate = DefaultableBoolean.True

There are other various settings to add each column to its respective group and to setup visual aspects of each column (all color/border stuff, nothing that would affect the functionality of the grid). 

I've tried your recommendation of setting the grid to allow updates, etc.  Nothing is making these buttons show up. 

Anything I posted look like it could be the culprit? 

Thanks!

UGH... finally found the culprit...  I wrote up a C# test application with the code I pasted above and it worked fine... so I started looking at other seemingly-unrelated areas of the program.  I had a logic error earlier in the RowLayout where it was SUPPOSED to be setting the Editor property of fields that have % values in them to a %-formatted Editor.  It was, however, setting this editor to all non-$ cells, including the images column... it didn't manifest in my grid visually because I was setting the $ cells editor later (overwriting the incorrect % editor). 

Apparently if the cell.Editor property is set... setting the cell.EditorComponent property later won't work as expected. 

Thanks for your help guys... I bet it's frustrating to try to fix problems with systems where you can only see what the programmer thinks is related :)

Hi Rocky,

The Editor property on the column will override the EditorComponent. So that explains it.

Hi Rocky,

The EditorButton is applying a mouseover appearance setting and I can't find any way to override it.  Any ideas? Not the end of the world but I'd like to make it so that hovering over the cell or button doesn't visually change it.  However, I can't cancel the mouseenterelement event as I'm using that for tooltips on the editor buttons. 

My guess is that this is caused by the button's DisplayStyle. The Office2007ScrollBarButton style is not really intended to be used, except for Scrollbar buttons. There is a probably another style on the list that will give you want you want without the hotracking.

If not, then the HotTracking background color must be coming from something in the code or maybe an isl file.

The part in bold is my problem... I've tried adding an appearance to the appearances collection of the grid and then assigning the appearance like this:  
                    editorbutton.Appearance = ugMeasures.DisplayLayout.Appearances("NotesImageNotesFound")

This doesn't do anything.  The only way I've been able to apply appearance settings to the appearance of the EditorButton is to do it manually, which is not ideal.  I can deal with this though and do the cleanup, but if there's a way to do it the correct way (reusing appearance objects), I'd like to do it that way. 

This looks like it should work, assuming you are setting the properties on the Appearance object correctly when you create it.

The appearance might be overriden by Themes. But if that were the case, then setting properties directly on the editorButton.Appearance would not behave any differently. And the same is true of AppStyling.
