我在 Bootstrap 模式中有一个列表框和一个文本框。我需要使用列表框中选定的值更新文本框。我的问题是为了从列表框中获取选定的值,我需要进行自动回发。回发导致模式关闭。

这是完整的模态代码:

 <div id="modalBillOLMapping" class="modal colored-header" style="display:none" >
<div class="md-content">
<div class="modal-header">
<button type="button" data-dismiss="modal" aria-hidden="true" class="close md-close"><i class="icon s7-close"></i></button>
<h3 class="modal-title">
<asp:Label ID="Label1" runat="server" Text="Field Mapping"></asp:Label>
</h3>
</div>
<div class="modal-body form" style="padding: 0px!important;">
<asp:UpdatePanel runat="server">
<ContentTemplate>

</ContentTemplate>
</asp:UpdatePanel>

</div>

这是我的代码:

    protected void lbConBillOLDocNumber_SelectedIndexChanged(object sender, EventArgs e)
{
txtConBillOLDocNumber.Text = lbConBillOLDocNumber.SelectedItem.Text;

}

我需要将列表框中选定的文本值放入文本框中。我确实知道我得到了正确的值,因为上面代码中的警报显示了正确的值(但由于模式关闭,我不知道文本框是否正在更新。)我需要用所选值填充文本框的列表框,我需要模式保持打开状态。我意识到我的做法可能完全错误,因此欢迎提出任何改进建议。

最佳答案

您可以使用 AJAX UpdatePanel (如下例所示)来消除每次回发时刷新整个页面的要求,并允许部分渲染您的案例的特定区域,它将是模态主体。

HTML

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
<%-- AJAX UpdatePanel section--%>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
</asp:DropDownList>
<br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</ContentTemplate>
</asp:UpdatePanel>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</form>

后台代码

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
// Bind DropDownList1 with some testing data
DropDownList1.Items.Add(new ListItem() { Text = "Item 001", Value = "1" });
DropDownList1.Items.Add(new ListItem() { Text = "Item 002", Value = "2" });
DropDownList1.Items.Add(new ListItem() { Text = "Item 003", Value = "3" });
DropDownList1.Items.Add(new ListItem() { Text = "Item 004", Value = "4" });
DropDownList1.Items.Add(new ListItem() { Text = "Item 005", Value = "5" });
}
}

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
TextBox1.Text = DropDownList1.SelectedValue;
}
