asp.net - Initial SelectedValue in DropDownList not posting back when re-selected -
i have dropdownlist
following markup:
<asp:updatepanel id="updatepanel1" runat="server" childrenastriggers="true" updatemode="always"> <contenttemplate> <asp:dropdownlist id="ddlcampaignmodule" runat="server" onselectedindexchanged="ddldynamictype_selectedindexchanged" autopostback="true"> <asp:listitem value="-1">none</asp:listitem> <asp:listitem value="10">category menu</asp:listitem> <asp:listitem value="11">best sellers</asp:listitem> <asp:listitem value="12">best reviews</asp:listitem> </asp:dropdownlist> </contenttemplate> </asp:updatepanel>
in code behind select second option category menu
. if run code , select other option posts ddldynamictype_selectedindexchanged
if re-select second option (after selecting 1 of other ones) postback isn't triggered.
am missing simple here?
sounds selecting 2nd option in code behind, regardless of postback... ensure if isn't!
if (!ispostback) { //select 2nd item }
