如何隐藏在ASP.NET表单列 [英] how to hide columns in ASP.NET webform

问题描述

在我PrinterPackage ASPX 的文件我有以下的用户控制：

In my PrinterPackage.aspx file i have the following 'User Control':

<%@ Register Src="~/ProvisionControls/DeferredTaxRollforwardControl.ascx" TagPrefix="uc9" TagName="DeferredTaxesRollforwardControl" %> 
   ...
   ...
 <div>
    <uc9:DeferredTaxesRollforwardControl ID="DeferredTaxesRollforwardControl1" runat="server" />
 </div>

它调用控制文件DeferredTaxRollforwardControl ASCX 。'包含如下定义我的表：

which calls the control file 'DeferredTaxRollforwardControl.ascx' that contains my table defined as follows:

<table style="width: 4600px; border-spacing:0px;" border="0" frame="hsides" cellpadding="2" cellspacing="1">

<tr id = "tblTempDiff"> //want to import this


<td style="width:7.6%;" width="2px;" class="paintYellowTotalLeftBold">
    Grand Total Current
</td>
<td style="width:2.8%;" width="2px;" class="paintYellowTotalBold">
    <asp:Label ID="lblGrandTotalUnadjustedBeginningBalance" runat="server" Text=""></asp:Label>
</td>
... and more <td>

我试图显示表，也隐藏着一些使用以下code在我PrinterPackage列 aspx.cs 文件：

 TableRow row = DeferredTaxesRollforwardControl1.FindControl("tblTempDiff") as TableRow;
        row.Cells[0].Visible = true;
        row.Cells[1].Visible = true;
        row.Cells[2].Visible = true;
        row.Cells[3].Visible = true;
        row.Cells[4].Visible = true;
        row.Cells[5].Visible = true;
        row.Cells[6].Visible = true;
        row.Cells[7].Visible = true;
        row.Cells[8].Visible = true;
        row.Cells[9].Visible = false;
        row.Cells[10].Visible = false;
        row.Cells[11].Visible = false;
        row.Cells[12].Visible = false;

但是，这似乎并没有拿起表行 tblTempDiff ，并给了我一个空值来代替。我怎样才能导入数据来自的TableRow tblTempDiff 到行，然后隐藏我想隐藏什么列？

But, this doesn't seem to pick up the table row tblTempDiff and gives me a null value instead. How can i import the data from the TableRow tblTempDiff into row and then hide whatever columns i want to hide?

请向我提问，如果你需要更多的信息，因为我知道，当谈到解释我的问题我不是最好的人。

推荐答案

在code背后看不到的＆LT; TR＆GT; 创建，因为它不是一个服务器控制。在 =服务器属性添加到＆LT; TR＆GT; ：

The code behind cannot see the <tr> you created because it's not a server control. Add the runat="server" attribute to the <tr>:

<tr id="tblTempDiff" runat="server">

和使用<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.ui.htmlcontrols.htmltablerow%28v=vs.110%29.aspx\"相对=> System.Web.UI.HtmlControls.HtmlTableRow 的nofollow的，而不是的TableRow 。两个不同的东西。

And use System.Web.UI.HtmlControls.HtmlTableRow instead of TableRow. Two different things.
