我想嵌套2个中继器。第二个中继器在第一个中继器的itemDataBind事件上绑定了数据。嵌套中继器Asp.net ItemDataBound不叫？
<asp:Repeater ID="FolderRepeater" runat="server" OnItemDataBound="CategoryRepeater_ItemDataBound">
<ItemTemplate>
<p><%# Container.DataItem("DocumentName")%></p>
<asp:Repeater ID="someRepeater" runat="server">
<ItemTemplate>
<p>TEST<%# Container.DataItem("NodeAlias")%></p></br>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
首先中继势必在pageLoad的，和第二中继势必开往事件一号转发器的项目数据。但是，似乎我的ItemDataBound事件没有被调用，因为没有显示第二个重复项目。
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
Dim datasetFolders As New DataSet()
Dim da As SqlDataAdapter = New SqlDataAdapter()
Dim sqlQry As String
Dim conn As New SqlConnection(CMS.DataEngine.SqlHelper.ConnectionString)
sqlQry = "SELECT * FROM dbo.CMS_Document WHERE DocumentNamePath LIKE '/Galerie/%' AND DocumentExtensions IS NULL"
da.SelectCommand = New SqlCommand(sqlQry, conn)
conn.Open()
da.Fill(datasetFolders)
conn.Close()
FolderRepeater.Dispose()
FolderRepeater.DataSource = datasetFolders
FolderRepeater.DataBind()
End Sub
并且这将是itemDataBound事件。 response.write（“test”）中的文本没有显示在我的网页上，所以我怀疑它从来没有打过电话？
Protected Sub CategoryRepeater_ItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs) Handles FolderRepeater.ItemDataBound
Response.Write("test")
Dim item As RepeaterItem
item = e.Item
Dim imageFolder As New DataSet
Dim da As SqlDataAdapter = New SqlDataAdapter()
Dim sqlQry As String
Dim conn As New SqlConnection(CMS.DataEngine.SqlHelper.ConnectionString)
sqlQry = "SELECT * FROM dbo.View_CONTENT_File_Joined WHERE NodeAliasPath LIKE '/Galerie/" & e.Item.DataItem("DocumentName") & "/%'"
da.SelectCommand = New SqlCommand(sqlQry, conn)
conn.Open()
da.Fill(imageFolder)
conn.Close()
Dim someRepeater As Repeater
someRepeater = e.Item.FindControl("someRepeater")
someRepeater.DataSource = imageFolder
someRepeater.DataBind()
End Sub
你必须从外中继器的'ItemDataBound'数据绑定它。另外，你不应该在回发上进行数据绑定。所以检查它'如果不是IsPostBack然后DataBindRepater（）' –
它正在外部中继器的ItemDataBound数据绑定。不是吗？ – lucafik
