This doesn'tdo the ellipsis like you wanted, but it seems to work pretty well: 

    public class MyCreationFilter : IUIElementCreationFilter
    {
        #region IUIElementCreationFilter Members

        public void AfterCreateChildElements(UIElement parent)
        {
            if (parent is EditorWithTextUIElement)
            {
                ImageUIElement imageUIElement = parent.GetDescendant(typeof(ImageUIElement)) as ImageUIElement;

                if (imageUIElement != null)
                {
                    imageUIElement.Rect = new Rectangle(
                        imageUIElement.Rect.X,
                        imageUIElement.Rect.Y,
                        imageUIElement.Image.Width,
                        imageUIElement.Rect.Height);
                }
            }
        }

        public bool BeforeCreateChildElements(UIElement parent)
        {
            return false;
        }

        #endregion
    }

Hi,

It's not really a good idea to set properties on the appearance of a cell inside a CreationFilter. Setting properties like you are doing here will cause the grid's elements to get dirtied, which will cause hte CreationFilter to get called again.

Why are you setting the Image and ImageHAlign inside the CreationFilter? The InitializeRow event would be a much better place to do this. Or even using a DrawFilter and setting properties on the AppearanceData passed in, rather than the Appearance of the cell would be a much better way to go.

Also... what version of the grid are you using? I tested this out using the oldest support version (2009 Vol. 2) and the images the cell are not stretched, they are centered by default.

Hi Mike,

  I have to display both image and text within my cell. In AfterCreateChildElements() I do

 cellUIElement.Cell.Appearance.Image = Properties.Resources.preview_AddPreferences;

cellUIElement.Cell.Appearance.ImageHAlign =

HAlign.Left;

This works fine. However my cell's height can increase to display the text on 2 or more lines, but my image will also gets bigger and I don't want that.

I tried to do the following to reset the image to a normal size, but it didn't work.

 ImageUIElement imageUIElement = parent.GetDescendant(typeof(ImageUIElement)) as ImageUIElement;

                if (imageUIElement != null)
                {
                    imageUIElement.Rect = new Rectangle(
                        imageUIElement.Rect.X,
                        imageUIElement.Rect.Y,
                        imageUIElement.Image.Width,
                        imageUIElement.Rect.Height);
                }

I also tried other things like creating a new ImageUIElement and add it to the CellUIElement and then modifying EditorWithTextDisplayTextUIElement.Rect, but this didn't work as well.

Do you know why I can't resize my image or change EditorWithTextDisplayTextUIElement.Rect?

Thanks,

The above didnt work for me, if column datatype at datasource level is of type image.

Also note: if you want editor in image column , then dont set column style = image, instead set datasource column datatype as image

,otherwise it makes readonly

If you intend to show a tooltip on the ellipsis or haveit respond to a click in some way, then you are right, it's probably better to show the ellipsis as a second element - whether it be an ImageUIElement or whatever.

The ellipsis you see on text is probably just drawn as part of the text using the TextTrimming property. The GDI+ text rendering handles that automatically and that's part of the same drawing operation. That only applies to text, anyway, so tha's not what you want. 

The ellipsis I was referring to is the one used by editors like UltraTextEditor. Put an UltraTextEditor control on a form and set ShowOverflowIndicator to true and then make the text longer than the control. It's not really an ellipsis, but it has a similar function. Like I said, I'm not sure how tightly tight that element is to the editors, so it might be easier for you to just use an ImageUIElement, but the OverflowIndicator might have some other useful functionality - so it might be worth looking into.
