I won't give you the code but I'll give you the theory so you can code it yourself. If you get stuck with a specific part of your code, post it and we'll have a look.
What you want is a very simple 3 step process.
In the treeview's mousedown event , get the node at the mouse point. Set the selectednode to be that node If it's not null and is a 'Parent' node, call the treeview's DoDragDrop method.
In the listview's dragover event, set the effect property of the event arguments to copy.
In the litview's DragDrop event, convert the data to a treenode (would be a good idea to null check here too) then convert it and it's nodes (children) to a listviewitem with listviewsubitems and add to your listview.

Hi,
Thanq for ur Suggestion But i tried inthes way..can you corect the problem here.
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;
}
}

void treeView1_ItemDrag(object sender, ItemDragEventArgs e)
{
TreeNode nodeData = (TreeNode)e.Item;
treeView1.SelectedNode = nodeData;
if ((string)nodeData.Tag == "Parent" && nodeData.Nodes.Count == 2)
treeView1.DoDragDrop(nodeData, DragDropEffects.Copy);
}
void listView1_DragOver(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.None;
TreeNode nodeData = (TreeNode)e.Data.GetData(typeof(TreeNode));
if (nodeData != null && (string)nodeData.Tag == "Parent" && nodeData.Nodes.Count == 2)
e.Effect = DragDropEffects.Copy;
}

{

if (nodeData != null && (string)nodeData.Tag == "Parent" && nodeData.Nodes.Count == 2)
{
ListViewItem newItem = new ListViewItem(nodeData.Text);
foreach (TreeNode childNode in nodeData.Nodes)
{
ListViewItem.ListViewSubItem newSub = new ListViewItem.ListViewSubItem();
newSub.Text = childNode.Text;
newItem.SubItems.Add(newSub);
}
listView1.Items.Add(newItem);
}
}

Hello,
I have a below issue with the windows service.
I have a method as below
private void OnElapsedTime(object source, ElapsedEventArgs e)
{
log.Info("OnElapsedTime");
BillPay.ProcessOrder();
}
I have a timer set for 1 mins in OnStart method
protected override void OnStart(string[] args)
{
//ad 1: handle Elapsed event
timer.Elapsed += new ElapsedEventHandler(OnElapsedTime);
//ad 2: set interval to 1 minute (= 60,000 milliseconds)
timer.Interval = 60000 ;
//ad 3: enabling the timer
timer.Enabled = true;
}
The problem:
If my ProcessOrder() method which process all orders do not get completed in 1 mins I see unexpected results in the database with duplicate entry. I suspect the method ProcessOrder() get called again onTimeElapsed, I have commit and rollback statements too. But does not help.
Please suggest as how can I resolve this issue.
Regards,
Pavas

Stop the timer while you call the method, so that it does not start the event handler in another thread.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
So when it will again start?

I believe, timer will start right after the method call is over..let me try this

It will start when you turn the timer on again.

Put your work into a thread, and fire off the thread each time the timer ticks. You can even prevent multiple threads from kicking off with appropriate code in the tick handler.
Personally, I wouldn't use a Timer object because it's the lowest priority message in Windows, and in a busy system, there's no guarantee the message will even be handled. Instead, I use a BackgroundWorker object for timers because they can be easily aborted. Sure, it's more code (go forbid a programmer should have to actually write some code), but it's much more reliable and controllable.

That is true for a Windows Forms timer running on the UI thread. But the OP is writing a service, so he's probably using System.Threading.Timer or System.Timers.Timer. AFAIK, both of them use the ThreadPool, and so does BackgroundWorker

i can do parent dynamic gridview --> child dynamic gridview but ive a problem at the interface of triple dynamic gridviews how do i do for that ??

I prefer to 'Hungarian Notation' than 'PascalCase' to named controls.
e.g.
I like use btnOk, btnCancel, txtName, txtAge
but not okButton, cancelButton, nameTextBox, ageTextBox.
which one do you like? and why?
Glad to discuss with you and best wishes.

The former, but only with controls. When I need to store the user's name in a string, it's always userName, never strUserName.

I've never ever worked anywhere where there has not been someone who given the choice I would not work with again. It's a job, you do your work, put up with the people you don't like, accept there are probably people there that don't like you a lot, and look forward to the weekends.

Yes, I'll named control like txtUsername, and named variable userName.
But now, I have to named control like userNameTextBox... but I don't like...

The actual class: MyTextBox
The class instance: myTextBox
Its properties and events: Text ... TextChanged
Why, to follow the convention that is used almost everywhere, and so I can see instantly if I'm working with an instance or a static

I use buttonOK, checkboxCheckMe, etc. That way, all controls of the same type are grouped in the same place in intellisense.
You could take it a step further and maybe use ctlButtonOK, and ctlCheckboxCheckMe, and that would put *all* of the controls in one single group in intellisense, yet still separate the controls by type within the group.

Agree with you, especially for the same type control.

Try using WMI to get the device.
