        GridViewCommandColumn commandCol = new GridViewCommandColumn("Action");
        commandCol.Name = "Action";
        ASPxGridView1.Columns.Add(commandCol);
    }
    // Creates a custom command button.
    (ASPxGridView1.Columns["Action"] as 
    GridViewCommandColumn).CustomButtons.Add(CreateCustomButton());
}

GridViewCommandColumnCustomButton CreateCustomButton() {
    GridViewCommandColumnCustomButton customBtn = new GridViewCommandColumnCustomButton();
    customBtn.ID = "action1";
    customBtn.Text = "Action1";
    customBtn.Visibility = GridViewCustomButtonVisibility.BrowsableRow;
    return customBtn;
}

protected void ASPxGridView1_CustomButtonCallback(object sender,
