我目前正在尝试在我的网页表单中动态添加HTML控件,但每次在另一个控件中插入控件时,错误“无法获取[control]的内部内容,因为内容不是文字”(尝试查看innerHtml或innerText时)会弹出,并且似乎找不到原因。
这是我使用的代码:
Dim newsList As New HtmlControls.HtmlGenericControl
newsList.TagName = "ul"
Dim i As Integer = 0
For Each newsDR As DataRow In newDS.Tables(0).Rows
i += 1
Dim stri As String = i.ToString()
Dim newsListItem As New HtmlControls.HtmlGenericControl
newsListItem.TagName = "li"
newsListItem.ID = "newsListItem" + stri
Dim newsTitle As New HtmlControls.HtmlGenericControl
newsTitle.TagName = "h1"
newsTitle.ID = "newsTitle" + stri
Dim newsAnchor As New HtmlControls.HtmlAnchor
newsAnchor.ID = "newsAnchor" + stri
newsAnchor.InnerHtml = newsDR("NewsTitle")
newsAnchor.HRef = "#"
newsTitle.Controls.Add(newsAnchor)
Dim newsSummary As New HtmlControls.HtmlGenericControl
newsSummary.TagName = "div"
newsSummary.ID = "newsSummary" + stri
newsSummary.InnerHtml = newsDR("NewsSummary")
newsListItem.Controls.Add(newsTitle)
newsListItem.Controls.Add(newsSummary)
newsList.Controls.Add(newsListItem)
