尝试使用以下代码将为您提供帮助：

.aspx代码：

  <asp:DataList ID="LocList" runat="server" RepeatDirection="vertical" 
RepeatColumns="18" RepeatLayout="Table" OnItemDataBound="DataList_ItemDataBound" OnItemCommand="DataList_ItemCommand"> 
<ItemTemplate>
<asp:LinkButton ID="lkLoc" runat="server" Text='<%# Eval("WHLOC") %>'  ForeColor="#000" Font-Names="calibri" Font-Size="Medium" onclick="lk_Click" />
    </ItemTemplate>
</asp:DataList>
<asp:Label ID="lbl1" runat="server"></asp:Label>

.aspx.cs代码在这里：

   Protected Sub DataList_ItemCommand(ByVal source As Object, ByVal e As DataListCommandEventArgs)

        Dim lkLoc As LinkButton = CType(e.Item.FindControl("lkLoc"), LinkButton)
        lbl1.Text = lkLoc.Text

    End Sub

将数据列表链接按钮的文本值返回到标签中
