。net问题
在top.aspx中有个按钮<asp:Button ID="Button1" runat="server" OnClick="Button1_Click1" Text="Button" />
<asp:DropDownList
ID="DropDownList1" runat="server" >
</asp:DropDownList>
当我点击这个按钮时 protected void Page_Load(object sender, EventArgs e)
{
Hashtable ht = (Hashtable)Application["ht"];
this.DropDownList1.DataSource = ht;
this.DropDownList1.DataTextField ="key";
this.DropDownList1.DataValueField = "value";
this.DropDownList1.DataBind();
if (!IsPostBack)
{
Button1.Attributes.Add("onClick", "window.showModalDialog(\"showModalDialog.aspx\",\"\",\"dialogWidth:500px;dialogHeight:300px\");");
}
弹出益而高页面对话框是：showModalDialog.aspx
