					Hello, 

 

A fix will be available in LIB Version 2019.1.415 scheduled for April 15th. Exposing an API for using a custom RadGridView control in the popup form.



When fix is released you will be able to use custom RadGridView as grid element of the MultiColumnComboBox as follows: 



using System;


using Telerik.WinControls;


using Telerik.WinControls.UI;


  


namespace MCCBCustomRadGridView


{


    public partial class RadFormCustomGrid : Telerik.WinControls.UI.RadForm


    {


        public RadFormCustomGrid()


        {


            InitializeComponent();


        }


  


        private void RadFormCustomGrid_Load(object sender, EventArgs e)


        {


            this.customersTableAdapter.Fill(this.nwindDataSet.Customers);


        }


    }


  


    public class MyRadMultiColumnComboBox : RadMultiColumnComboBox


    {


        public override string ThemeClassName


        {


            get


            {


                return typeof(RadMultiColumnComboBox).FullName;


            }


        }


  


        protected override RadMultiColumnComboBoxElement CreateMultiColumnComboBoxElement()


        {


            return new MyRadMultiColumnComboBoxElement();


        }


    }


  


    public class MyRadMultiColumnComboBoxElement : RadMultiColumnComboBoxElement


    {


        protected override Type ThemeEffectiveType


        {


            get


            {


                return typeof(RadMultiColumnComboBoxElement);


            }


        }


  


        protected override RadPopupControlBase CreatePopupForm()


        {


            MultiColumnComboPopupForm popupForm = new MyMultiColumnComboPopupForm(this);


            popupForm.EditorControl.Focusable = false;


            popupForm.MinimumSize = this.DropDownMaxSize;


            popupForm.MaximumSize = this.DropDownMaxSize;


            popupForm.Height = this.DropDownHeight;


            popupForm.VerticalAlignmentCorrectionMode = AlignmentCorrectionMode.SnapToOuterEdges;


            popupForm.HorizontalAlignmentCorrectionMode = AlignmentCorrectionMode.Smooth;


            popupForm.RightToLeft = this.RightToLeft ? System.Windows.Forms.RightToLeft.Yes : System.Windows.Forms.RightToLeft.Inherit;


            this.WirePopupFormEvents(popupForm);


  


            return popupForm;


        }


    }


  


    public class MyMultiColumnComboPopupForm : MultiColumnComboPopupForm


    {


        internal bool closed;


  


        public MyMultiColumnComboPopupForm(RadMultiColumnComboBoxElement element)


            : base(element)


        { }


  


        protected override GridViewHostItem CreateEditorElement()


        {


            return new MyGridViewHostItem();


        }


  


  


        /// <summary>


        /// Fires when the popup is opened.


        /// </summary>


        protected override void OnPopupOpened()


        {


            base.OnPopupOpened();


            closed = false;


        }


  


        /// <summary>


        /// Fires when the popup is closed.


        /// </summary>


        /// <param name="args">A RadPopupClosedEventArgs instance


        /// that contains information about what caused the popup to close.</param>


        protected override void OnPopupClosed(RadPopupClosedEventArgs args)


        {


            base.OnPopupClosed(args);


            closed = true;


        }


    }


  


    public class MyGridViewHostItem : GridViewHostItem


    {


        public MyGridViewHostItem()


            : base(new MyRadGridView())


        { }


    }


  


    public class MyRadGridView : RadGridView


    {


        #region Ctor


  


        public MyRadGridView()


        {


            this.GridBehavior = new MultiColumnComboGridBehavior();


        }


  


        protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e)


        {


            MyMultiColumnComboPopupForm form = this.Parent as MyMultiColumnComboPopupForm;


            if (form != null && form.closed)


            {


                return;


            }


  


            base.OnMouseDown(e);


        }


        #endregion


  


        #region Methods


  


        protected override bool ProcessFocusRequested(RadElement element)


        {


            return false;


        }


  


        public override string ThemeClassName


        {


            get


            {


                return "Telerik.WinControls.UI.RadGridView";


            }


            set


            {


                base.ThemeClassName = value;


            }


        }


  


        #endregion


    }


}
