hello frds,
I am trying to draw line by drag and drop between two checkedlistbox where both checkedlistbox is an object of checkedlistbox control. While i try to take start point by mousedown event on checkedlistbox and endpoint by dragdrop event.
but problem is when I drop the mouse, checkedlistbox ctr not activate. So dragdrop event not fire.
plz provide help, if possible code then give me.
thank you .

Please show the code you have for the drag/drop routines

My code is here
in this
chktable1 is a checkedlistbox
spl11 is panel control

void listbox1_SelectedIndexChanged(object sender, EventArgs e)
        {
//here I create chktable1 at every select item of listbox on panel 

                chktable1.MouseDown += new MouseEventHandler(chktable1_MouseDown);
                chktable1.MouseMove += new MouseEventHandler(chktable1_MouseMove);
                spl11.DragEnter += new DragEventHandler(spl11_DragEnter);
                chktable1.DragDrop += new DragEventHandler(chktable1_DragDrop);

        }


  private System.Windows.Forms.RichTextBox DebugWindow;

        bool mDraging = false;
        void chktable1_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
                mDraging = true;
        }
        private string mRecallFileName;
        void chktable1_MouseMove(object sender, MouseEventArgs e)
        {
            DebugWindow = new System.Windows.Forms.RichTextBox();
            if (!mDraging)
                return;

            if (e.Button != MouseButtons.Left)
                return;

            //Initial condition

            if (chktable1.SelectedItem==null)
                return;
            mRecallFileName =(string)chktable1.SelectedItem.ToString();

            //Make sure that there is a filename associated with this node
            if (mRecallFileName == string.Empty)
            {
                mDraging = false;
                return;
            }

            DebugWindow.AppendText("Dragging File: " + mRecallFileName + "\n");
            chktable1.DoDragDrop(mRecallFileName,DragDropEffects.Copy | DropEffects.Move);


        }
        void spl11_DragEnter(object sender, DragEventArgs e)
        {
            if (e.Data.GetDataPresent(DataFormats.Text))
                e.Effect = DragDropEffects.Copy;
            else
                e.Effect = DragDropEffects.None;
        }

 void chktable1_DragDrop(object sender, DragEventArgs e)
        {
            if (chktable1.CanFocus == true)
            {
                mDraging = false;
                chktable1.DoDragDrop(mRecallFileName, DragDropEffects.None);
                MessageBox.Show("ii"+mRecallFileName);
            }
        }
