本演示是让你知道如何多个值绑定至ListBox显示为选中。ListBox在default情况之下,SelectionMode为Single,因此为了多选,而需要设置此属性为Multiple。在实现之前,可以先看到Insus.NET所实现最终效果,gif动画,无声音:
.aspx:
<asp:TextBox ID="TextBox1" runat="server" Width="300"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="Binding" OnClick="Button1_Click" />
<br />
<br />
<asp:ListBox ID="ListBox1" runat="server" Height="100" SelectionMode="Multiple" ></asp:ListBox>
<br />
<asp:Button ID="Button1" runat="server" Text="Binding" OnClick="Button1_Click" />
<br />

<asp:ListBox ID="ListBox1" runat="server" Height="100" SelectionMode="Multiple" ></asp:ListBox>
.aspx.cs中,首先是为ListBox准备数据,然后对ListBox控件进行数据绑定:
