Saludos.....
Tengo el siguiente codigo hecho en Dream + ASP.Net .....
Código:
<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<%@ Register TagPrefix="MM" Namespace="DreamweaverCtrls" Assembly="DreamweaverCtrls,version=1.0.0.0,publicKeyToken=836f606ede05d46a,culture=neutral" %>
<MM:DataSet
id="DataSet1"
runat="Server"
IsStoredProcedure="false"
ConnectionString='<%# System.Configuration.ConfigurationSettings.AppSettings("MM_CONNECTION_STRING_Conn") %>'
DatabaseType='<%# System.Configuration.ConfigurationSettings.AppSettings("MM_CONNECTION_DATABASETYPE_Conn") %>'
CommandText='<%# "SELECT * FROM dbo.deptos" %>'
Debug="true"
></MM:DataSet>
<MM:PageBind runat="server" PostBackBind="true" />
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>Documento sin título</title>
</head>
<body>
<script runat="server">
sub page_load(sender as object, e as eventargs)
if not ispostback() then
depto.text="Gastos generales"
end if
end sub
sub cambio(sender as object, e as eventargs)
depto.text=numdept.selecteditem.value
end sub
</script>
<form runat="server">
<p>
<asp:DropDownList ID="numdept" DataSource="<%# DataSet1.DefaultView %>" DataTextField="depto" DataValueField="nombre" runat="server" OnSelectedIndexChanged="cambio" AutoPostBack="true"></asp:DropDownList>
</p>
<p> <asp:Label ID="depto" runat="server" /> </p>
</form>
</body>
</html>
pero cuando lo ejecuto y cambio el valor del dropdownlist se ve que refresca la pantalla y pero no me mantiene los datos que yo escogi..... me muestra los valores iniciales......Que me falta en el codigo?
Gracias
