Hi,

When we are updating the Dropdownlist from the Datatable, the value can not insert into the Dropdownlist it is showing blank only due to selected Index = -1

Kindly help me to resolve this issue.

During Update
C#
ddlcountry.text = dtCountry[0]["Country"].Tostring();

from database dtCountry = 'America'

IN Dropdownlist Source
XML
<asp:UpdatePanel ID="UpdatePanel4" runat="server">
   <ContentTemplate>
      <asp:DropDownList ID="ddlCountry" AutoPostBack ="true"
AppendDataBoundItems ="True" runat="server"
onselectedindexchanged="ddlCountry_SelectedIndexChanged"  Width="200px" >
      </asp:DropDownList>
   </ContentTemplate>
   <Triggers>
    <asp:AsyncPostBackTrigger ControlID ="ddlCountry"
   </Triggers>
</asp:UpdatePanel>

where's your code.. (i.e .cs file's code) ?

1 solution

Drop down selected index always starts from 0. So please give selected index of dropdown as 0 or more then it.
