Drag and Drop Treeview Item into Listview

[uday1302]

Hi All,
I have tried by seeing an example. See the below code. Here I have a Problem. Treeview has already one root node and twochild nodes with it.
They have to be dragged and dropped in listview.

The main Problem is wen I drag an item..the Itemdrag event is not fired.?? Please try to resolve it.

private void tvwSalesProducts_ItemDrag(object sender, ItemDragEventArgs e)
        { 
            tvwSalesProducts.DoDragDrop(e.Item, DragDropEffects.Copy | DragDropEffects.Move);
        }       
        private void lstMultiProItems_DragEnter(object sender, DragEventArgs e)
        {           
            e.Effect = DragDropEffects.Copy | DragDropEffects.Move;             
        }
        private void lstMultiProItems_DragDrop(object sender, DragEventArgs e)
        {
                if (e.Data.GetDataPresent("System.Windows.Forms.TreeNode", false))
                {
                    string[] Items = new string[5];
                    TreeNode SourceNode;
                    SourceNode = (TreeNode)e.Data.GetData("System.Windows.Forms.TreeNode");
                    Items[0] = Convert.ToString(SourceNode.Tag);
                    Items[1] = SourceNode.Text.ToString();
                    Items[2] = SourceNode.FirstNode.Text.ToString();
                    Items[3] = SourceNode.LastNode.Text.ToString();
                    lstMultiProItems.Items.Clear();
                    lstMultiProItems.Columns.Add("ID", 100, HorizontalAlignment.Left);
                    lstMultiProItems.Columns.Add("Product Name", 100, HorizontalAlignment.Left);
                    lstMultiProItems.Columns.Add("Selling Price", 100, HorizontalAlignment.Left);
                    lstMultiProItems.Columns.Add("Conversion", 100, HorizontalAlignment.Left);
                    ListViewItem Item1 = new ListViewItem(Items);
                    lstMultiProItems.Items.Add(Item1);
                    lstMultiProItems.AllowColumnReorder = false;
                    lstMultiProItems.FullRowSelect = true;
                }
        }

Please format your code using the CODE tags before posting.

Have you actually attached the event handler to the TreeView's event?

tvwSalesProducts.ItemDrag += new ItemDragEventHandler(this.tvwSalesProducts_ItemDrag);

Hi Dear,
I have added the event handler from front end design.

Thatz not a pronlem hope so

Yes, that the same. You should have the same line of code in your (formName).Designer.cs file.

Do you still have the problem? Did you try putting a breakpoint in tvwSalesProducts_ItemDrag to see if it really doesn't fire?
