Hi Friends,

country : INDIA


states : list show "TN,PONDI"


when i choose pondi ll redirect into "pondi.aspx"

but my drop down box was not show the selected value(i.e combo box again showed --- select--- but i need selected "PONDI" in combo after page redirect)

Select State: &nbsp;<asp:DropDownList ID="ddlstate" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlstate_SelectedIndexChanged">
<asp:ListItem Text="Select" Value="0">--select--</asp:ListItem>
<asp:ListItem Text="Pondicherry" Value="1">Pondicherry</asp:ListItem>
<asp:ListItem Text="TamilNadu" Value="2">Tamil Nadu</asp:ListItem>
</asp:DropDownList>

protected void ddlstate_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlstate.SelectedItem.Text == "Pondicherry")
