我有这个代码用于在aspx,后端vb.net中隐藏表和单元格.
代码 –
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
解决方法
将runat =“server”和ID添加到div中.然后,您可以使用其Visible属性隐藏div.
标记：
<div ID="myDiv" runat="server">Test DIV</div>
VB：
myDiv.Visible = False 'Hide the div. myDiv.Visible = True 'Show the div.
您可以使用控件集合循环访问子控件：
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
