You should post the code you have tried, and then it may be easier to understand what you're trying to do.

Hi,

Here's a simple example using a command you can adapt to your dialog.

    public class Commands
    {
        [CommandMethod("MIMT")]
        public void MultiInsertMText()
        {
            var doc = AcAp.DocumentManager.MdiActiveDocument;
            var db = doc.Database;
            var ed = doc.Editor;
            using (var tr = db.TransactionManager.StartTransaction())
            {
                var curSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
                while (true)
                {
                    using (var mtext = new MText())
                    {
                        mtext.Contents = "Drag me !";
                        mtext.Height = db.Textsize;
                        mtext.Rotation = Math.PI / 2.0;
                        mtext.Attachment = AttachmentPoint.MiddleCenter;
                        mtext.TextStyleId = db.Textstyle;
                        curSpace.AppendEntity(mtext);
                        tr.AddNewlyCreatedDBObject(mtext, true);
                        MTextJig jig = new MTextJig(mtext);
                        var result = ed.Drag(jig);
                        if (result.Status != PromptStatus.OK)
                        {
                            mtext.Erase();
                            break;
                        }
                        db.TransactionManager.QueueForGraphicsFlush();

                    }
                }
                tr.Commit();
            }
        }
    }

    class MTextJig : EntityJig
    {
        MText mtext;
        Point3d basePt, dragPt;

        public MTextJig(MText mtext) : base(mtext)
        {
            this.mtext = mtext;
            basePt = mtext.Location;
        }

        protected override SamplerStatus Sampler(JigPrompts prompts)
        {
            var options = new JigPromptPointOptions("\nInsertion point: ");
            options.BasePoint = basePt;
            options.UseBasePoint = true;
            options.UserInputControls =
                UserInputControls.Accept3dCoordinates |
                UserInputControls.NullResponseAccepted | // allows Enter to break the loop
                UserInputControls.UseBasePointElevation;
            var result = prompts.AcquirePoint(options);
            if (result.Value.IsEqualTo(dragPt))
                return SamplerStatus.NoChange;
            dragPt = result.Value;
            return SamplerStatus.OK;
        }

        protected override bool Update()
        {
            mtext.Location = dragPt;
            return true;
        }
    }
