Hide tr or td in a table using vb.net in codebehind
提问by ITTIHAD FC.
In my masterpage I have links for users also the authorization is different like admin and regular user.
在我的主页中，我有用户链接，授权也不同，如管理员和普通用户。
links under each other and I can hide the hyperlinks depending on authorization status but the problem is i.e when I have 3 links the second link for the admin the link will hide when the user is regular and the link place empty like 123 1 3.
链接相互关联，我可以根据授权状态隐藏超链接，但问题是当我有 3 个链接时，管理员的第二个链接将隐藏当用户是常规链接并且链接位置为空时，如 123 1 3。
So I have an idea using table each link in one tr but I can`t hide td or tr because Visible is not in properties.
所以我有一个想法在一个 tr 中使用 table 每个链接，但我不能隐藏 td 或 tr 因为 Visible 不在属性中。
any help? thank you
有什么帮助吗？谢谢你

According to how to hide a having asp.net control:
you can give ID either to the TD or TR to which you want to hide/show with the runat="server" and also you can take that tr/td inside the div tag and give id to that div tag and also runat=server attribute and after that you can pro grammatically hide/show that div.
like
<pre> <tr id="trhide" runat="server"> </tr> </pre>in code behind write
trhide.visible=true/false
您可以将 ID 指定给要使用 runat="server" 隐藏/显示的 TD 或 TR，也可以将该 tr/td 放入 div 标签中，并将 id 指定给该 div 标签以及 runat=server属性之后，您可以在语法上隐藏/显示该 div。
喜欢
<pre> <tr id="trhide" runat="server"> </tr> </pre>在后面写的代码中
trhide.visible=true/false

In the master page VB code behind add a public procedure: Then call the public set from your aspx page.
在母版页 VB 代码后面添加一个公共程序：然后从您的 aspx 页面调用公共集。
'======================================================================================================
'Set Tab No invisible
'======================================================================================================
Public Sub setTabNumberLabel(visible As Int16)
If visible = 0 Then
td_page.Visible = False
Else
td_page.Visible = True
End If
End Sub
The master aspx would be:
主 aspx 将是：
<table style="width:100%">
<!--<tr style="background-color:#565656;">-->
<tr>
<td style="width:15%;text-align:left;vertical-align:bottom;padding-left:20px;">Stategic Energy Assessment ( <asp:Label ID="lbl_year_ended" runat="server" /> )</td>
<td style="text-align:center;vertical-align:bottom;"><asp:Label ID="lbl_utility_name_and_id" runat="server" /></td>
<td id="td_page" runat="server" style="width:15%;text-align:right;vertical-align:bottom;padding-right:20px;">Tab No: <asp:Label ID="lbl_page" runat="server" /></td>
</tr>
<tr><td colspan="3" style="vertical-align:central"><hr /></td></tr>
<tr>
<td style="width:15%;text-align:left;vertical-align:central">
<asp:Label ID="lbl_print_version" runat="server" Text="View Printable Vision" Visible="false" />
</td>
<td style="font-size:larger; font-weight:bold; text-align:center; text-transform:capitalize;vertical-align:central">
<asp:Label ID="lbl_schedule_name" runat="server" />
</td>
<td style="width:15%;text-align:right;vertical-align:central;padding-right:20px;">
<asp:LinkButton ID="btn_footnotes" runat="server" Visible="false">Footnotes</asp:LinkButton>
</td>
</tr>
<%--<tr><td colspan="3" style="vertical-align:central" class="auto-style1"></td></tr>--%>
<tr><td colspan="3" style="vertical-align:central; padding-right:20%;padding-left:20%; ">
<i><asp:Label ID="lbl_headnotes" runat="server" Text="" /></i></td></tr>
<tr><td colspan="3" style="vertical-align:central"><hr /></td></tr>
</table>

The other answer is correct and works fine. Just adding complete piece of code.
另一个答案是正确的并且工作正常。只需添加完整的代码。
It's quite amusing that you don't need to add runat=serverfor a table but you can still hide tr for that table using runat attribute.
很有趣的是，您不需要runat=server为表添加，但您仍然可以使用 runat 属性隐藏该表的 tr。
<table>
<tr>
<td>aa</td><td>bb</td>
</tr>
<tr id="trHide1" runat="server">
<td>aa</td><td>bb</td>
</tr>
<tr id="trHide2" runat="server">
<td>aa</td><td>bb</td>
</tr>
<tr>
<td>aa</td><td>bb</td>
</tr>
</table>
Now just set properties in codebehind (hiding the tr)
现在只需在代码隐藏中设置属性（隐藏 tr）
trHide1.Visible = false;
trHide2.Visible = false;
