我在ASP.NET中有一个 gridview ,其中 asp:templatefield 包含每行一个按钮。在按钮上,我具有模态数据目标属性。
在gridview行边界上,我获取行的ID并调用方法 SerializedBoxChart(),该方法放入行的ID中并检索数据。但是,它看起来像遍历每一行,最后我在gridview的每一行中得到最后一行的数据。当我单击按钮时,它将打开带有最后一行数据的模态。我试图根据measureID为每一行分配数据,当您单击按钮时,它会打开该行数据。
当highcharts javascript运行脚本并将其放在div中时,我感觉与容器上ID冲突有关,但不知道如何解决。
<asp:TemplateField HeaderText="AvgDaysTaken" SortExpression="AvgDaysTaken">
<ItemTemplate>
<asp:Button type="button" runat="server" id="AvgDaysTaken" class="btn btn-primary" data-toggle="modal" data-target="#myBoxPlot" Text='<%# Eval("AvgDaysTaken") %>' />
</ItemTemplate>
</asp:TemplateField>
模式代码,其中包含带有ID容器的div,将在其中放置图形
<div class="container">
<!-- Modal -->
<div class="modal fade" id="myBoxPlot" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<div id="container" >
</div>
</div>
<div class="modal-footer">
<button type="button" id="close" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
使用c#获取箱形图的数据
public void SerializedBoxChart(int measureid)
{
string connectionstring = ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString;
SqlConnection cn = new SqlConnection(connectionstring);
SqlCommand cmd = new SqlCommand("[dbo].cr_fe_KPI_RPT_Summary", cn);
cmd.Parameters.AddWithValue("@SubTeamNo", SubTeam);
cmd.Parameters.AddWithValue("@Month", Month);
cmd.Parameters.AddWithValue("@Year", Year);
cmd.Parameters.AddWithValue("@ReportPeriod", ReportPeriod);
cmd.Parameters.AddWithValue("@controlID", ControlID);
cmd.Parameters.AddWithValue("@PracticeGroupID", PracticeGroup);
cmd.Parameters.AddWithValue("@Instructor", SearchInput.Text);
cmd.Parameters.AddWithValue("@MeasureID", measureid) ;
SqlDataAdapter da = new SqlDataAdapter(cmd);
cmd.CommandType = CommandType.StoredProcedure;
cn.Open();
SqlDataReader reader = cmd.ExecuteReader();
var chartValues = new List<string>();
var chartValues2 = new List<string>();
if (reader.HasRows)
{
while (reader.Read())
{
string name = reader.GetString(0);
if (name != "Total")
{
string str = reader["ChartData"].ToString();
string a = reader["MeasureDesc"].ToString();
string[] strList = str.Split(',');
// convert it in json
dataStr = JsonConvert.SerializeObject(strList, Formatting.None);
hiddenvariable.Value = dataStr;
hiddenvariablemeasuredesc.Value = a;
chartValues.Clear();
}
}
}
else
{
}
reader.Close(); // close the reader
cn.Close();
}
用于创建箱形图的javascript:
function CreateBoxPlot() {
var hv = $('#hiddenvariable').val();
console.log(hv);
var hvmeasure = $('#hiddenvariablemeasuredesc').val();
console.log(hvmeasure);
var chart;
var titleText = hvmeasure;
var subTitleText = 'Test Chart Subtitle';
var type = 'boxplot';
var data = [JSON.parse(hv).map(item => parseInt(item))]; //Doesnt work in IE
var $container = $('<div>').appendTo(document.body);
$(function () {
$('#container').highcharts({
chart: { type: type, inverted: true},
title: { text: hvmeasure },
subtitle: { text: subTitleText },
renderTo: $container[0],
legend: { enabled: false },
tooltip: {
shared: true,
crosshairs: true
},
plotOptions: {
series: {
pointWidth: 50
}
},
xAxis: {
visible: false
},
yAxis: {
visible: true,
title: {
text: 'Values'
},
plotLines: [{
value: 80,
color: 'red',
width: 2
}]
}
});
chart = $('#container').highcharts();
chart.addSeries({ data: data });
});
}

你有没有解决过这个问题?
我猜您没有发布所有代码,或者您对其进行了编辑,而遗漏了信息。
在 SerializedBoxChart
方法中,您创建两 (2) 个 List<String>
变量。每次通过您的 while loop
后都会清除一个 chartValues,而另一个 chartValues2 从未使用过。
我怀疑这是您试图保留的数据。
不要将此信息保存在临时 List<String>
变量中,您需要在页面上有一个 HTML 列表,您可以将数据发送到该列表。
如果您的 HTML 页面上有存储位置,例如 listView1
和 listView2
,您的代码将如下所示:
public void SerializedBoxChart(int measureid) {
var list1 = (ListView)FindControl("listView1");
var list2 = (ListView)FindControl("listView2");
if ((list1 != null) && (list2 != null)) {
string connectionstring = ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString;
var chartValues = new List<string>();
var chartValues2 = new List<string>();
using (var cmd = new SqlCommand("[dbo].cr_fe_KPI_RPT_Summary", new SqlConnection(connectionstring))) {
cmd.Parameters.AddWithValue("@SubTeamNo", SubTeam);
cmd.Parameters.AddWithValue("@Month", Month);
cmd.Parameters.AddWithValue("@Year", Year);
cmd.Parameters.AddWithValue("@ReportPeriod", ReportPeriod);
cmd.Parameters.AddWithValue("@controlID", ControlID);
cmd.Parameters.AddWithValue("@PracticeGroupID", PracticeGroup);
cmd.Parameters.AddWithValue("@Instructor", SearchInput.Text);
cmd.Parameters.AddWithValue("@MeasureID", measureid);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection.Open();
using (var reader = cmd.ExecuteReader()) {
if (reader.HasRows) {
while (reader.Read()) {
string name = reader.GetString(0);
if (name != "Total") {
string str = reader["ChartData"].ToString();
string a = reader["MeasureDesc"].ToString();
chartValues.Add(str);
chartValues2.Add(a);
string[] strList = str.Split(',');
// convert it in json
var dataStr = JsonConvert.SerializeObject(strList, Formatting.None);
hiddenvariable.Value = dataStr;
hiddenvariablemeasuredesc.Value = a;
}
}
}
// reader.Close(); don't need to close in a USING statement
}
}
list1.DataSource = chartValues;
list1.DataBind();
list2.DataSource = chartValues2;
list2.DataBind();
}
}
