我有一个数据库表Prospect
,它存储主键id &的版本。在web表单中有一个按钮Generate Proposal
,当点击该按钮时,将显示一个对话框,允许用户从下拉框中选择要生成的潜在客户的版本。我有一个方法,将检索版本从数据库的前景GetVersions()
,但不知道如何把它放在一个对话框,让用户选择版本。非常感谢任何帮助。
是否可以选择JQuery UI ?
你必须添加JQuery UI参考,可以在这里找到
这是JQuery UI对话框的文档
下面的代码取自我实现的一个解决方案。为了简单起见,我删除了相当多的代码。如果你需要任何说明,请告诉我。
HTML:<div id="MenuChangeSelection" title="Change Selection" class="MainDialog">
<div id="MenuChangeSelectionContent"></div>
</div>
JQuery: $("#YourRadBtnID").click(function () {
var yourDropDownMarkup = "<select><option value='Opt1'>Opt1</option></select>"; // Insert your dropdown markup or get your dropdown from the dom.
$("#MenuChangeSelectionContent").html(yourDropDownMarkup);
$("#MenuChangeSelection").dialog({
autoOpen: true,
modal: true,
width: 600,
height: 150,
buttons: {
"Save And Close": function() {
//Do something when Save And Close is clicked. eg. asynchronously post back to server.
},
"Cancel": function() {
$(this).dialog("close");
}
},
open: function () {
$('.ui-widget-overlay').addClass('custom-overlay');
},
close: function () {
$('.ui-widget-overlay').removeClass('custom-overlay');
}
});
});
CSS: .ui-widget-overlay.custom-overlay
{
background-color:black;
opacity:0.4;
filter:alpha(opacity=40); /* For IE8 and earlier */
}
这里有一小段代码供您入门。这使用jQuery对话框。
在aspx页面
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<asp:Button ID="generateProposal" runat="server" Text="Generate Proposal" OnClick="generateProposal_Click" />
<div id="popupContent" style="display: none">
<asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>
<br />
<br />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click1" />
</div>
<script type="text/javascript">
function showPopup() {
$(function () {
$("#popupContent").dialog();
});
}
</script>
然后在代码后面。
protected void generateProposal_Click(object sender, EventArgs e)
{
//the id of the prospect. Not clear from your question where this should come from
int proposalID = 6;
//sometimes a counter is just a counter
int counter = 0;
//clear old items from the dropdownlist
DropDownList1.Items.Clear();
//load the prospects from the database here and attach to dropdownlist
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlCommand command = new SqlCommand("prospect_select", connection))
{
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("@id", SqlDbType.Int).Value = proposalID;
try
{
//open the database connection
connection.Open();
SqlDataReader reader = command.ExecuteReader();
//loop all rows and add them to the dropdownlist
while (reader.Read())
{
DropDownList1.Items.Insert(counter, new ListItem(reader["prospect_name"].ToString(), reader["prospect_version"].ToString(), true));
counter++;
}
}
catch (Exception exception)
{
//handle the error if you want
}
}
//call the javascript function to open the dialog box
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "showPopup", "showPopup();", true);
}
