Hello Pat.

The MdiWindowListTool build its list of Windows based on the parent Form's MdiChildren array. The Form gets this list from an internal ArrayList in the MdiClient. Unfortunately, there is no sorting mechanism built into the MdiWindowListTool to allow you to manipulate the order.  You can submit a feature request to add this functionality here.

However, with a little reflection, you can sort the internal list using the follow code whenever a new child form is added:

        private ArrayList internalList;

        private void SortChildForms()

        {

            if (this.internalList == null)

            {

                //find the MdiClient

                foreach (Control control in this.Controls)

                {

                    MdiClient mdiClient = control as MdiClient;

                    if (mdiClient != null)

                    {

                        // use reflection to get the underlying children array

                        Type mdiType = mdiClient.GetType();

                        this.internalList = (ArrayList)mdiType.InvokeMember("children", System.Reflection.BindingFlags.GetField | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic, null, mdiClient, null);

                        break;

                    }

                }

            }

            // sort the children array

            this.internalList.Sort(new MdiChildComparer());

        }

        internal class MdiChildComparer : IComparer

        {

            #region IComparer Members

            public int Compare(object x, object y)

            {

                return string.Compare(((Form)x).Text, ((Form)y).Text);

            }

            #endregion

        }

I hope this helps you achieve your desired results. Let me know if I can be of any further assistance.

Chris
