Hiding <div> from vb.net code side
提问by reffe
I have this code for hiding a table and a cell in aspx, backend vb.net. Code -
我有这段代码用于在 aspx 中隐藏表格和单元格，后端 vb.net。代码 -
For Each row As HtmlTableRow In tab_a1.Rows
If row.ID = "a1" Then
For Each cell As HtmlTableCell In row.Cells
cell.Visible = (cell.ID = "a1")
Next
ElseIf row.ID = "b1" Then
For Each cell As HtmlTableCell In row.Cells
cell.Visible = (cell.ID = "b1")
Next
Else
row.Visible = False
End If
Next
Now instead of tables I'm using <div>tags. How can I use similar code and make div's visible and invisible?
现在我使用<div>标签而不是表格。如何使用类似的代码并使 div 可见和不可见？

Add runat="server"and an ID to your div. You can then hide the div using its Visibleproperty.
runat="server"向您的 div添加一个 ID。然后，您可以使用其Visible属性隐藏 div 。
Markup:
标记：
<div ID="myDiv" runat="server">Test DIV</div>
VB:
VB：
myDiv.Visible = False 'Hide the div.
myDiv.Visible = True 'Show the div.
You can loop through child controls using the controls collection:
您可以使用控件集合循环遍历子控件：
For Each child As Control In myDiv.Controls
If TypeOf child Is HtmlControl Then
Dim typedChild As HtmlControl = CType(child, HtmlControl)
'Search grandchildren, toggle visibility, etc.
End If
Next
