自动填充复选框 [英] Autocomplete with checkboxes

问题描述

我需要一个文本框上带有复选框的自动完成列表，我也应该可以选中取消选中复选框，当我检查一个或多个复选框时，项目应该显示在逗号分隔的文本框中。我该怎么办？

有没有可用的用户控件？

推荐答案

<asp:TextBox ID="TextBox1" runat="server" Width="300px"></asp:TextBox>
        <asp:CheckBoxList ID="CheckBoxList1" runat="server" AutoPostBack="true"

            onselectedindexchanged="CheckBoxList1_SelectedIndexChanged">
        <asp:ListItem Value="1">ListItem1</asp:ListItem>
        <asp:ListItem Value="2">ListItem2</asp:ListItem>
        <asp:ListItem Value="3">ListItem3</asp:ListItem>
        <asp:ListItem Value="4">ListItem4</asp:ListItem>
        <asp:ListItem Value="5">ListItem5</asp:ListItem>
        </asp:CheckBoxList>

protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)
{
    TextBox1.Text += CheckBoxList1.SelectedItem.Text+",";
}

试一试......这是最简单的实施，你必须做很多检查

喜欢

1.应该避免重复

2.取消选中它应该从文本框中删除而不是添加

ETC. ..





希望这有助于!!!
