C# 关于asp:表控件我们如何创建一个thead?
从对主题的分析中,我们可以看到我们创建了一个C# 关于asp:表控件我们如何创建一个thead?,c#,syntax,html-table,tablesorter,asp.net-3.5,C#,Syntax,Html Table,Tablesorter,Asp.net 3.5,从对主题的分析中,我们可以看到我们创建了一个TableHeaderRow,其中包含TableHeaderCells 但是他们添加了如下表头: myTable.Row.AddAt(0, headerRow); 其中输出HTML: <table id="Table1" ... > <tr> <th scope="column" abbr="Col 1 Head">Column 1 Header</th> <th scope=
TableHeaderRow
,其中包含TableHeaderCell
s
但是他们添加了如下表头:
myTable.Row.AddAt(0, headerRow);
其中输出HTML:
<table id="Table1" ... >
<tr>
<th scope="column" abbr="Col 1 Head">Column 1 Header</th>
<th scope="column" abbr="Col 2 Head">Column 2 Header</th>
<th scope="column" abbr="Col 3 Head">Column 3 Header</th>
</tr>
<tr>
<td>(0,0)</td>
<td>(0,1)</td>
<td>(0,2)</td>
</tr>
...
但是问题是关于
表控件。我本想建议您尝试声明性语法,但现在我知道您的意思了;以下代码…:
<asp:Table runat="server" ID="sometable">
<asp:TableHeaderRow BackColor="#ADD9E6">
<asp:TableHeaderCell ID="DataHeader" CssClass="Heading1" Text="Data Header" />
</asp:TableHeaderRow>
<asp:TableRow>
<asp:TableCell>Data</asp:TableCell>
</asp:TableRow>
</asp:Table>
如果在模板中命名列时可以使用DataGrid,它将适当地生成一个thead和tbody。刚刚找到了一种方法,我们确实需要使用从基控件继承的控件,例如表
public class myTable : System.Web.UI.WebControls.Table
{
protected override void OnPreRender(EventArgs e)
{
Table table = Controls[0] as Table;
if (table != null && table.Rows.Count > 0)
{
// first row is the Table Header <thead>
table.Rows[0].TableSection = TableRowSection.TableHeader;
// last row is the Footer Header <tfoot> (comment for not using this)
table.Rows[table.Rows.Count - 1].TableSection = TableRowSection.TableFooter;
FieldInfo field = typeof(WebControl).GetField("tagKey", BindingFlags.Instance | BindingFlags.NonPublic);
foreach (TableCell cell in table.Rows[0].Cells)
field.SetValue(cell, HtmlTextWriterTag.Th);
}
base.OnPreRender(e);
}
}
例如,您只需要使用它来代替基本控件:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
myGridView dg = new myGridView();
dg.DataSource = new string[] { "1", "2", "3", "4", "5", "6" };
dg.DataBind();
ph.Controls.Add(dg);
}
}
在aspx页面中,只需添加一个占位符,如:
<asp:PlaceHolder ID="ph" runat="server" />
请注意:这是VB.net对同一问题的回答,您可以使用任意数量的免费在线转换器将其转换为C#
使用thead&tbody创建一个简单的HTML表。我特别需要jQuery tablesorter插件的thead元素
Dim ta As Table
Dim thr As TableHeaderRow
Dim thc As TableHeaderCell
Dim tr As TableRow
Dim td As TableCell
ta = New Table
' make a header row & explicitly place it into the header section
thr = New TableHeaderRow
thr.TableSection = TableRowSection.TableHeader
' add cells to header row
thc = New TableHeaderCell
thc.Text = "ID"
thr.Cells.Add(thc)
thc = New TableHeaderCell
thc.Text = "DESC"
thr.Cells.Add(thc)
' create a data row & append cells to it
tr = New TableRow
td = New TableCell
td.Text = "101"
tr.Cells.Add(td)
td = New TableCell
td.Text = "VB.net is not so bad."
tr.Cells.Add(td)
' append the header & row to the table
ta.Rows.Add(thr)
ta.Rows.Add(tr)
' add the new table to your page
Page.Controls.Add(ta)
在这件事上我已经晚了一百万年,但我只需要做同样的事。它的处理方式与栅格视图基本相同
foreach (var item in dynamicData)
{
var c = new TableHeaderCell()
c.Text = item.Whatever;
hr.Cells.Add(c);
}
//This is the important line
hr.TableSection = TableRowSection.TableHeader;
MyTable.Rows.Add(hr);
将TableSection=“TableHeader”
添加到TableHeaderRow,如下所示:
<asp:TableHeaderRow ID="TableHeaderRow2"
runat="server" TableSection="TableHeader" >
我不能使用声明性语法:(这是一个动态表,只有在运行时我才知道有多少列是关于什么的……这个想法使用一个由设计师生成的XML来创建“网格”DataGrid默认情况下不这样做您不知道,如果您有数据源,为什么我要手工做所有事情?如果我可以简单地做myTable.DataSource=myDataSource;
,那么计算列数、行数等,我只想创建
,因为其他一切都已经存在!
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
myGridView dg = new myGridView();
dg.DataSource = new string[] { "1", "2", "3", "4", "5", "6" };
dg.DataBind();
ph.Controls.Add(dg);
}
}
<asp:PlaceHolder ID="ph" runat="server" />
Dim ta As Table
Dim thr As TableHeaderRow
Dim thc As TableHeaderCell
Dim tr As TableRow
Dim td As TableCell
ta = New Table
' make a header row & explicitly place it into the header section
thr = New TableHeaderRow
thr.TableSection = TableRowSection.TableHeader
' add cells to header row
thc = New TableHeaderCell
thc.Text = "ID"
thr.Cells.Add(thc)
thc = New TableHeaderCell
thc.Text = "DESC"
thr.Cells.Add(thc)
' create a data row & append cells to it
tr = New TableRow
td = New TableCell
td.Text = "101"
tr.Cells.Add(td)
td = New TableCell
td.Text = "VB.net is not so bad."
tr.Cells.Add(td)
' append the header & row to the table
ta.Rows.Add(thr)
ta.Rows.Add(tr)
' add the new table to your page
Page.Controls.Add(ta)
foreach (var item in dynamicData)
{
var c = new TableHeaderCell()
c.Text = item.Whatever;
hr.Cells.Add(c);
}
//This is the important line
hr.TableSection = TableRowSection.TableHeader;
MyTable.Rows.Add(hr);
<asp:TableHeaderRow ID="TableHeaderRow2"
runat="server" TableSection="TableHeader" >
