两个选择,一是将数据源中数据拼成字符串放到页面隐藏控件中,然后页面加载时用Js取隐藏控件值拆分并给Select绑定,二是像1楼一样拼一个Select
[解决办法]
Sub HtmlSelect(ByVal HtmlSelect As HtmlSelect, ByVal dt As DataTable, ByVal Text As String, ByVal Value As String)
HtmlSelect.Items.Add(New ListItem("请选择", ""))
Dim i As Integer
For i = 0 To dt.Rows.Count - 1
With dt.Rows(i)
HtmlSelect.Items.Add(New ListItem(.Item(Text), .Item(Value)))
End With
Next
End Sub
