Hello,

In the demos on your PC where the Telerik Controls are installed is a good demo of using Drag and Drop with a RadListControl which of course also shows adding and removing items from 2 RadListBoxes.

If you need further help however, please let me know
Thanks
Richard

Hi Richard,
I have seen the demo but I am still a bit confuse about exact working of same.
Can you please elobrate this using any event of list view?

As I am working on functionality of adding item from RadListControl to RadListView on single click and not drag and drop.
I have set the ViewType property of RadListView to ItemView.

I am using event of SelectedIndexChanged to add item to RadListView and at same time I am removing it from RadListControl.
Then on ItemRemoving event of radListView I am adding the same Item back to RadListControl.
While doing so I am getting exception of Collection can not be modified as it is read only.

Can you please help me with this?

Hello Sandesh,

Thank you for writing.

RadListView does not have a ViewType called ItemVIew. It has ListView, IconsView and DetailsView. 

As to the approach used, I would suggest that you use the MouseDown event. Here is a sample when RadListView is in ListView mode:

public Form1()
{
    InitializeComponent();

    radListControl1.MouseDown += radListControl1_MouseDown;
    radListView1.MouseDown += radListView1_MouseDown;
}

void radListView1_MouseDown(object sender, MouseEventArgs e)
{
    SimpleListViewVisualItem el = radListView1.ElementTree.GetElementAtPoint(e.Location) as SimpleListViewVisualItem;
    if (el != null)
    {
        radListControl1.Items.Add(el.Data.Text);
        radListView1.Items.Remove(el.Data);
    }
}

void radListControl1_MouseDown(object sender, MouseEventArgs e)
{
    RadListVisualItem el = radListControl1.ElementTree.GetElementAtPoint(e.Location) as RadListVisualItem;
    if (el != null)
    {
        radListView1.Items.Add(el.Data.Text);
        radListControl1.Items.Remove(el.Data);
    }
}

I hope this helps.
