在一张表里数tr？(WebGrid)
在一张表里数tr？(WebGrid)
提问于 2013-07-15 21:00:32
我有一个表，我想检查它是否填充。
下面我展示了如何构建网格以及它在运行时环境中的外观；我将如何计算行数？
如何构建网格：
@using System.Dynamic
@{
var result = new List<dynamic>();
//Model.TrackingNumber = Model.RequestNumber.ToString();
foreach (var proprow in Model.DDS)
{
var row = (IDictionary<string, object>)new ExpandoObject();
Dictionary<string, object> eachPropRow = (Dictionary<string, object>)proprow;
var fileName = proprow["Township"] + ", " + proprow["Erf"] + ", " + proprow["Portion"] + ", " + proprow["Property_Type"] + ", " + proprow["Unit"] + " " + "V?, " + DateTime.Now.ToString("(yyyy-MM-dd (HH.mm))"); //+ DateTime.Now.ToString("(yyyy-MM-dd (HH.mm))")
foreach (KeyValuePair<string, object> keyValuePair in eachPropRow)
{
System.Web.HtmlString linkID;
if (keyValuePair.Key == "Prop_ID")
{
linkID = Html.ActionLink(keyValuePair.Value.ToString(), "Valuation", new { PropID = keyValuePair.Value, Token = Model.Token, fileName, RequestNumber = Model.RequestNumber, ClientName = Model.ClientName, ReasonForValuation = Model.ReasonForValuation, ContactPerson = Model.ContactPerson, ContactNumber = Model.ContactNumber, Relation = Model.Relation, AccountNumber = Model.AccountNumber, BondAmount = Model.BondAmount, PurchasePrice = Model.PurchasePrice}, new { @class = "DownloadLink" });
row.Add(keyValuePair.Key, linkID);
}
else
{
row.Add(keyValuePair);
}
}
result.Add(row);
}
var grid = new WebGrid(result,null,null,30,false,false);
@*@grid.GetHtml(tableStyle: "grid", headerStyle: "head", alternatingRowStyle: "alt");*@
@grid.GetHtml(
tableStyle: "grid",
headerStyle: "grid-header",
alternatingRowStyle: "grid-alternating-row", //grid-alternating-row
selectedRowStyle: "grid-selected-row",
rowStyle: "grid-row-style"
)
}下面我列出了运行时控制台中显示的表：
<table class="grid">
<thead>
<tr class="grid-header"><th scope="col">Prop_ID</th>
<th scope="col">Erf</th>
<th scope="col">Street</th>
<th scope="col">Unit</th>
<th scope="col">Portion</th>
<th scope="col">Size</th>
<th scope="col">Suburb</th>
<th scope="col">Township</th>
<th scope="col">Province</th>
<th scope="col">Property_Type</th>
<th scope="col">Owner</th>
<th scope="col">Title_Deed_No</th>
<th scope="col">Purch_Price</th>
<th scope="col">Purch_Date</th>
</tr>
</thead>
<tbody>
<tr class="grid-row-style">
<td><a class="DownloadLink" href="/ReturnProperties/Valuation?PropID=14351160&Token=f7a9d22c-ce87-45df-a8b1-a05bdba9e068&fileName=HIGHVELD%20EXT%207%2C%201402%2C%200%2C%20FH%2C%20%20V%3F%2C%20(2013-07-15%20(14.53))&RequestNumber=45735864378386V1">14351160</a></td>

您可以使用.NET XML库和XPath来确定这一点。或者使用免费的在线XPath测试工具，将您的XML复制粘贴到其中，并使用以下XPath表达式：
//table[@class='grid']//tr使用XML1.xAPI，您可以实例化一个新的.NET文档并执行XPath，如下所示：
XmlDocument tableDoc = new XmlDocument();
tableDoc.LoadXml( /* A string containing the HTML here -- but it better be well-formed */);
var trCount = tableDoc.SelectNodes("//table[@class='grid']//tr").Cast<XmlNode>().Count();如果您使用的是XHTML，那么应该使用下面的XPath，这样就不必担心需要通过SelectNodes(...)创建和使用NamespaceManager
//*[local-name()='table' and @class='grid']//*[local-name()='tr']还有较新的XML-to- .NET。我对它还不够熟悉，不能给你一个很好的例子。
HTH。

要获取webgrid的行数-
var grid = ISGetObject("WebGrid1");
var getTotal = grid.TotalRows;
var getChangesTotal = grid.RootTable.GetChangesCount();
alert(getTotal + getChangesTotal);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
