Hello,

I got a tree with an unbound column like this:

UltraTreeNodeColumn ultraTreeNodeColumn = new UltraTreeNodeColumn();
ultraTreeNodeColumn.DataType = typeof(bool);
ultraTreeNodeColumn.AllowCellEdit = AllowCellEdit.Full;
ultraTreeNodeColumn.Key = notationEdit.ID.ToString();
ultraTreeNodeColumn.Tag = notationEdit;
ultraTreeNodeColumn.LayoutInfo.OriginX = 0;
ultraTreeNodeColumn.LayoutInfo.OriginY = -1;
ultraTreeNodeColumn.LayoutInfo.MinimumCellSize = new Size(20, 20);
ultraTreeNodeColumn.LayoutInfo.PreferredCellSize = new Size(20, 20);
ultraTreeNodeColumn.LayoutInfo.SpanX = 1;
ultraTreeNodeColumn.LayoutInfo.SpanY = 1;
ultraTreeNodeColumn.AutoSizeMode = ColumnAutoSizeMode.None;

while creating nodes I want to insert a (Ultra)CheckEditor in the a cell, like this:

UltraCheckEditor checkEditor = new UltraCheckEditor();
checkEditor.Visible = false;
checkEditor.UseFlatMode = DefaultableBoolean.True;
checkEditor.Size = new Size(16, 16);
checkEditor.Appearance.Image = Icons16.Placeholder;
checkEditor.Appearance.ImageHAlign = HAlign.Center;
checkEditor.Appearance.ImageVAlign = VAlign.Middle;
checkEditor.CheckedAppearance.Image = Icons16.OPDProcess;
checkEditor.CheckedAppearance.ImageHAlign = HAlign.Center;
checkEditor.CheckedAppearance.ImageVAlign = VAlign.Middle;
checkEditor.Style = EditCheckStyle.Button;
checkEditor.DrawFilter = new NoFocusRectDrawFilter();

this.ExtensionManager.ExtendedObject.Controls.Add(checkEditor);

e.Node.Cells[2].EditorComponent = checkEditor;

but I got 2 problems here:

First: the image for false is not displayed at all (the placeholder image has a very eye catching color), instead no image is displayed after clicking the cell with a value of true. So changing the cell value from true to false will draw  no image, the true image just disapears. Why?

Second: The check box always draws the focus rectangle, this is not desired. I was unable to get rid of it even with a draw filter that usually solved this issue.

what I already tried:

- using a CheckEditor, but this control doesnt even provide appearance for false?

- Creating the UltraCheckEditor with the designer

- deactivating all styles etc.

Any help is welcome!
