如何使用带有tr的visible = ？

In a aspx page I have table as container and tds have different Repeaters in it.

在aspx页面中，我将表作为容器，tds中有不同的Repeater。

I know table is not a databound control but was wondering there may be a way to use data from dt to control visibility of a tr or any other html control ?

我知道table不是数据绑定控件但是想知道可能有办法使用dt中的数据来控制tr或任何其他html控件的可见性？

I just tried Page.Databind() but it was not successful and there was an error "Table is not a data bound control"

我只是尝试了Page.Databind（），但它没有成功，并且出现错误“表不是数据绑定控件”

Please guide.

请指导。

You should use DISPLAY property to ensure that a blank space is not left by the row that is hidden instead of the VISIBLE property.

您应该使用DISPLAY属性来确保隐藏的行不会留下空白而不是VISIBLE属性。

With out knowing or seeing your code block for a a sible gle its difficult to second guess but if your using "Show" or Hide" as the swutches to decide wether to show or hide a row.........

在不知道或看到你的代码块的情况下，如果你使用“显示”或“隐藏”作为旋转来决定显示或隐藏一行.........

maybe your code should read as follows.....

也许你的代码应该如下所示......

<tr <%=GetDisplayStatus('switch') %>>

where switch is either "show" or "hide" and your SERVERSIDE function to get the display status should be as follows..

其中switch是“show”或“hide”，你的SERVERSIDE函数获取显示状态应如下所示。

Function GetDisplayStatus(SwitchState as String) as String
  If SwitchState = "show" then
    return " style=" & chr(34) & "display: block;" & chr(34)
  ElseIf SwitchState = "hide" Then
    return " style=" & chr(34) & "display: none;" & chr(34)
  Else
    ' no action otherwise
    return ""
  End If
End Function

Please let me know if that works for you.

如果这对你有用，请告诉我。

When working with ASP.Net, it's important to know which properties are processed by the server and which are html. When you use a <%# tag, the value in your expression is written directly to the web server's response stream. It's too late at this point to assign to a server property. Visible is a server property.

使用ASP.Net时，了解服务器处理哪些属性以及哪些属性是html非常重要。使用<％＃标记时，表达式中的值将直接写入Web服务器的响应流。此时分配给服务器属性为时已晚。 Visible是服务器属性。
