drag drop reorder on gridview

Hi I want to sort a gridview on my asp.net page using drag and drop functionality. I want that on dropping a row the new sort order is stored in the database. Following is the code..the client ID always returns null

<asp:GridView ID="dg_Link" runat="server" AllowPaging="True" AutoGenerateColumns="False"
 CellPadding="4" DataKeyNames="LinkID" OnDataBound="dg_Link_DataBound" OnPageIndexChanging="dg_Link_PageIndexChanging"
  OnRowCommand="dg_Link_RowCommand" Width="100%" ForeColor="#333333" GridLines="None"
  OnRowCreated="dg_Link_RowCreated" EnableModelValidation="True" OnSelectedIndexChanged="dg_Link_SelectedIndexChanged"
OnRowDataBound="dg_Link_RowDataBound">
<Columns>
<asp:TemplateField HeaderStyle-Width="5%" HeaderText="" ItemStyle-CssClass="PhotoGridItemText"ItemStyle-Width="5%">
   <HeaderTemplate>
          <asp:CheckBox runat="server" ID="chkHeader" />
   </HeaderTemplate>
<ItemTemplate>
    <asp:CheckBox ID="chkSelect" runat="server" EnableViewState="true" />
</ItemTemplate>
</asp:TemplateField>
<asp:Templat

Web Forms have the potential to change Web programming by introducing a new programming model built around server-side controls-a model in which controls render their own UIs by generating HTML to return to clients and firing events that are handled by server-side scripts. Since all the action takes place on the Web server, virtually any browser can run a Web Forms app. And thanks to Visual Studio .NET, building a Web Forms app is a lot like using Visual Basic: just drop a control onto a form then write an event handler. This article describes the Web Forms programming model, how it fits with ASP.NET, and introduces DataGrid, TextBox, and other classes in the .NET Framework class library.

Building on the browser-based org chart featuring VML (Vector Markup Language) described previously in Microsoft Internet Developer, this article takes you through the process of refining that sample app by using XML, XSL, and JScript code to create a new, improved version. Drag and drop editing is added to the org chart interface thanks to built-in support found in Internet Explorer 5.0. XML and JScript allow data manipulated on the screen to be saved back to the server in its native format. The final product of this combination of XML, XSL, and VML is a high performance, scalable Internet app that uses processing on the client to reduce stress for the server.

Hello all

How to make asp.net treeview drag and drop enabled on web. I am unable to find any javascript and there is not any event to make treeview drag and drop enabled.

Hey everyone, I have a treeview and a listview on my ASP.NET application. However, with treeview I can drag and drop it to where ever I want it on my page. I tried this with listview, but it wouldn't let me. Listview automatically positions itself along the left side of my application. What I'm wanting to do is put my treeview along the right side and then put my treeview along the left side of the application. Any ideas on why I can't do this or suggestions on how I might be able to do this?

By the way, I'm running Visual Studio 2010 and using .NET FRAMEWORK 4.
