    I have used the Listbox with Drag and Drop functionality. 

    My problem is that listbox contains the lots of data and when I drag data from one listbox to another it gives an error like:
    "A script on this page is causing your web browser to run slowly.  If it continues to run, your computer might become unresponsive."

    I have attached the screen shot of the Error.

    I am using telerik version 2012, 2, 710, 40

    I have more than 248 records in the listbox

    Hi Urwi,

    Unfortunately I couldn't replicate the issue at my end. Please have a look into the following code snippet.

    <telerik:RadListBox ID="RadListBox1" runat="server" Width="200px" Height="200px"
        AllowTransfer="true" TransferToID="RadListBox2" AutoPostBackOnTransfer="true"
        EnableDragAndDrop="true" DataSourceID="SqlDataSource1" DataTextField="OrderID"
    <telerik:RadListBox ID="RadListBox2" runat="server" Width="200px" Height="200px"
            <telerik:RadListBoxItem Text="Item1"></telerik:RadListBoxItem>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Northwind_newConnectionString %>"
        SelectCommand="SELECT [OrderID] FROM [Orders]">

    Please Provide your code if it doesn't help.
