。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

背后代码是using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Collections.Generic;
public partial class test : System.Web.UI.Page{
Hashtable ht;
protected void Page_Load(object sender, EventArgs e){
if (!Page.IsPostBack){
ht = new Hashtable();
ViewState["ht"] = ht;
}
}
protected void Button_Click(object sender, EventArgs e){
ht= (Hashtable)ViewState["ht"];
foreach (ListItem i in ListBox1.Items) {
if (i.Selected == true){
ListBox2.Items.Add(i.Text);
ht.Add(i.Text.ToString(), i.Value.ToString());
}
}
int[] indexToDel = ListBox1.GetSelectedIndices(); //取得所有选取值的index集合
int cnt = indexToDel.Length;
for (int i = cnt - 1; i >= 0; i--) {
ListBox1.Items.RemoveAt(indexToDel[i]);
}
}
protected void Button2_Click(object sender, EventArgs e){
ht = (Hashtable)ViewState["ht"];
int[] indexToDel = ListBox2.GetSelectedIndices(); //取得所有选取值的index集合
int cnt = indexToDel.Length;
foreach(ListItem i in ListBox2.Items){
if (i.Selected == true) {
ht.Remove(i.Text.ToString());}
}
for (int i = cnt - 1; i >= 0; i--){
ListBox2.Items.RemoveAt(indexToDel[i]);
}
}
protected void Button3_Click(object sender, EventArgs e){
ht = (Hashtable)ViewState["ht"];
Application["ht"] = ht;
Response.Redirect("right_top.aspx");
Response.Write("<script language=javascript>") ;
Response.Write("window.returnValue='false';window.close()") ;
Response.Write("</script>");
// Response.Write(" <script language=javascript>window.open('right_top.aspx');window.returnValue='True';window.close();</script>");
}
}
当我点击Button3_Click 时对话框为什么关不掉，而是出现一个right_top.aspx对话框，我想把right_top.aspx对话框关掉，怎么解决啊？
[解决办法]
点击Button3_Click 时,你想关哪个对话框,不是很明白
"Response.Redirect("right_top.aspx");" 就是重定向到了right_top.aspx,去掉就没有了
