drag div value into gridview

In grid instead of normal column use itemTemplate and place Textbox in it and then try to drag the div data to your grid. It won't reject your request :)

Try to implement following line of code in your GridView

<asp:GridView ID="GridView1" Runat="server" >
    <Columns>
<asp:TemplateField HeaderText="AcceptInput">
<ItemTemplate>
 <input type="Text" name="txtInput" runat="server">
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView> 

I am sure this will work. If it doesn't please let me know.
