带有 CommandArgument 的列表视图中的链接按钮
我正在使用 VS 2010、vb.net、.net 4。
我有一个列表视图，其中在 asp:tablecell 中包含一个 asp:linkbutton。问题是命令参数不是正确的值。
<asp:LinkButton ID="lbICS" runat="server" CommandName="cmdICS" CommandArgument='<%# eval("tblCalendarID")%>' Text='<%# eval("tblCalendarID").ToString %>'/>
当您查看它时，您会发现命令争论和文本绑定到相同的属性。我的文本属性读取为 386，但是当我单击 386 文本时，会触发 _ItemCommand 事件。当我执行 e.CommandArgument 时，该值是 46。我不明白我做错了什么。
Protected Sub lvCalendar_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewCommandEventArgs) Handles lvCalendar.ItemCommand If e.CommandName = "cmdICS" Then Dim mCalId As Integer = CInt(e.CommandArgument)
希望有人能帮忙
I'm using VS 2010, vb.net, .net 4.
I have a list view that holds a asp:linkbutton in an asp:tablecell. The problem is that the command argument is not the right value.
<asp:LinkButton ID="lbICS" runat="server" CommandName="cmdICS" CommandArgument='<%# eval("tblCalendarID")%>' Text='<%# eval("tblCalendarID").ToString %>'/>
when you look at it, you'll see that the command arguement and the text are bound to the same property. My text property reads 386, but when i click on the 386 text, the _ItemCommand event fires. when i do an e.CommandArgument, the value is 46. I don't understand what i'm doing wrong.
Protected Sub lvCalendar_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewCommandEventArgs) Handles lvCalendar.ItemCommand If e.CommandName = "cmdICS" Then Dim mCalId As Integer = CInt(e.CommandArgument)
hope someone can help
