背后的代码:

Code behind:

DataTable Dt = new DataTable(); DataTable Dt2 = new DataTable(); //save protected void Button2_Click(object sender, EventArgs e) { if (TextBox1.Text == string.Empty) { lblStatus.Text = "Enter value "; return; } if (ViewState["Dt"] == null) { DataColumn col = new DataColumn("test"); col.DataType = System.Type.GetType("System.String"); Dt.Columns.Add(col); } else { Dt = (DataTable)ViewState["Dt"]; } DataRow dr = Dt.NewRow(); dr[0] = TextBox1.Text;; Dt.Rows.Add(dr); ListView1.DataSource = Dt; ListView1.DataBind(); ViewState.Add("Dt", Dt); lblStatus.Text = "your Item saved "; TextBox1.Text = string.Empty; } protected void ListView1_SelectedIndexChanging(object sender, ListViewSelectEventArgs e) { ListView1.SelectedIndex = e.NewSelectedIndex; lblStatus.Text = "your Item selected "; Dt = (DataTable)ViewState["Dt"]; ListView1.DataSource = Dt; } //move protected void Button1_Click(object sender, EventArgs e) { //retrive the from datatable Stored in Viewstate Dt = (DataTable)ViewState["Dt"]; //check on the viewstate if not exist i will create strucre for the table if (ViewState["Dt2"] == null) { DataColumn col = new DataColumn("test"); col.DataType = System.Type.GetType("System.String"); Dt2.Columns.Add(col); } else { Dt2 = (DataTable)ViewState["Dt2"]; } // this can be useful if you can select more than item thorugh checkbox etc . // object[] xx = Dt.Rows[1].ItemArray; //foreach (string item in xx) //{ // string yy = item[0].ToString(); //} //stor the value of selected item in local variable string ItemValue = Dt.Rows[ListView1.SelectedIndex][0].ToString(); //remove the item from Datatable in listview1 Dt.Rows.RemoveAt(ListView1.SelectedIndex); //create new row in 2th datatable , storeing the value DataRow dr2 = Dt2.NewRow(); dr2[0] = ItemValue; Dt2.Rows.Add(dr2); ListView2.DataSource = Dt2; ListView2.DataBind(); ViewState.Add("Dt2", Dt2); ListView1.DataSource = Dt; ListView1.DataBind(); ViewState.Add("Dt", Dt); lblStatus.Text = "your Item Moved "; }

<div> <asp:ListView ID="ListView1" runat="server" onselectedindexchanging="ListView1_SelectedIndexChanging"> <ItemTemplate> <tr> <td> <asp:LinkButton ID="lnkSelect" Text="Select" CommandName="Select" runat="server" /> </td> <td> <%# Eval("test")%> </td> <br /> </tr> </ItemTemplate> <SelectedItemTemplate> <tr style="background-color: #FFFF66; color: #808000;"> <td> <asp:LinkButton ID="lnkSelect" Text="Select" CommandName="Select" runat="server" ForeColor="Red" /> </td> <td style="background-color: #FFFF66; color: #808000;"> <%# Eval("test")%> </td> <br /> </tr> </SelectedItemTemplate> </asp:ListView> <br /> <asp:Button ID="Button1" runat="server" Text="Move" onclick="Button1_Click" style="height: 26px" /> <asp:Label ID="lblStatus" runat="server"></asp:Label> <br /> <asp:ListView ID="ListView2" runat="server"> <ItemTemplate> <tr style="background-color: #00FF00"> <td> <%# Eval("test")%> </td> <br /> </tr> </ItemTemplate> </asp:ListView> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:Button ID="Button2" runat="server" Text="Save" onclick="Button2_Click" /> </div>

可能对您有帮助.. for(int i = 0; i< = ListBox1.Items.Count-1; i ++) { ListBox2.Items.Add(ListBox1.Items [i]); May this help you.. for (int i = 0; i <= ListBox1.Items.Count - 1; i++) { ListBox2.Items.Add(ListBox1.Items[i]);
