create a data source data table or data set based on a list view selection and bind it to your gird view.

Hi,Use the below code

This is simple eg by using the list.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
       {
           List<string> namelist = new List<string>();
           if (DropDownList1.SelectedIndex == 0)
           {
               namelist.Add("Abi");
               namelist.Add("Anand");
               namelist.Add("Arun");

               GridView1.DataSource = namelist;
               GridView1.DataBind();
           }
           else
           {
               List<string> nameslist = new List<string>();
               nameslist.Add("Balu");
               nameslist.Add("Banu");
               nameslist.Add("Batman");
               GridView1.DataSource = nameslist;
               GridView1.DataBind();
           }
       }

.aspx

XML

<asp:DropDownList ID="DropDownList1" runat="server"
       onselectedindexchanged="DropDownList1_SelectedIndexChanged" AutoPostBack="true" >
   <asp:ListItem>
   a
   </asp:ListItem>
   <asp:ListItem>
   b
   </asp:ListItem>
   </asp:DropDownList>
   <asp:GridView ID="GridView1" runat="server">
   </asp:GridView>
