In WinForms, how can I create a delete button in a DevExpress GridControl?

I'm trying to create a delete button at the right of every row in a DevExpress GridControl, like this:

enter image description here

What I've done is added another column and set its ColumnEdit property to an instance of RepositoryItemButtonEdit. I handle the ButtonClick event, to delete a row.

I can determine which row I'm on from this code:

myGridView.GetRow(myGridView.FocusedRowHandle);

Because I don't want a text editor on my button, I set the TextEditStyle to HideTextEditor.

By default, the button shows an ellipsis.

To remove the ellipsis, I adjusted the Buttons property on the RepositoryItemButtonEdit. I set the Kind to Glyph and set the image to my X icon.

Unfortunately that seems to simply remove the button altogether.

Does anyone know a better way to do this, or a way to show a button with an image on it, in each grid row?

I have summarized what I found in the DevExpress forum:

Use the ButtonEdit control and set the TextEditStyle property to HideTextEditor. The Repository Item has a Buttons collection through which you can add a caption, image etc.

In the Buttons collection, change the "Kind" property to "Glyph". You can use the CustomRowCellEdit event to conditionally apply editors on a cell-by-cell basis. Make sure you set the Button's Kind property to "Glyph" and set the Caption property to whatever text you'd like:

DevExpress.XtraEditors.Repository.RepositoryItemButtonEdit buttonEdit = 
    new DevExpress.XtraEditors.Repository.RepositoryItemButtonEdit();
buttonEdit.Buttons[0].Kind = DevExpress.XtraEditors.Controls.ButtonPredefines.Glyph;
buttonEdit.Buttons[0].Caption = "X";
buttonEdit.TextEditStyle =             
    DevExpress.XtraEditors.Controls.TextEditStyles.HideTextEditor;
e.RepositoryItem = buttonEdit;

You should handle the GridView's CustomRowCellEdit event, construct a new RepositoryItemButtonEdit and assign it to the e.RepositoryItem property.

Let me know if that works.

I discovered that there is actually a delete button kind. So, I do everything as in the question, but instead of choosing the kind Glyph, I choose Delete, and I don't need to select an image.
