处理来自 Repeater 页脚的控制事件
假设我有以下中继器。
<asp:Repeater ID="MyRepeater" runat="server" onitemdatabound="MyRepeater_ItemDataBound">
<FooterTemplate>
</table>
<asp:Button ID="btnPrevious" runat="server" Text="<" />
<asp:Label ID="lblCurrentPage" runat="server" Text="<%# PagingStatus() %>" />
<asp:Button ID="btnNext" runat="server" Text=">" />
</FooterTemplate>
</asp:Repeater>
如何处理来自 btnPrevious
和 btnNext
的点击事件?
我已尝试以下操作:
protected void MyRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
Button btnPrevious = (Button)e.Item.FindControl("btnPrevious");
Button btnNext = (Button)e.Item.FindControl("btnNext");
if (btnPrevious != null)
btnPrevious.Click += btnPrevious_Click;
if (btnNext != null)
btnNext.Click += btnNext_Click;
}
但这失败了(该事件从未引发)..
Assuming I have the following repeater.
<asp:Repeater ID="MyRepeater" runat="server" onitemdatabound="MyRepeater_ItemDataBound">
<FooterTemplate>
</table>
<asp:Button ID="btnPrevious" runat="server" Text="<" />
<asp:Label ID="lblCurrentPage" runat="server" Text="<%# PagingStatus() %>" />
<asp:Button ID="btnNext" runat="server" Text=">" />
</FooterTemplate>
</asp:Repeater>
How can I handle the click events from btnPrevious
and btnNext
?
I have tried the following:
protected void MyRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
Button btnPrevious = (Button)e.Item.FindControl("btnPrevious");
Button btnNext = (Button)e.Item.FindControl("btnNext");
if (btnPrevious != null)
btnPrevious.Click += btnPrevious_Click;
if (btnNext != null)
btnNext.Click += btnNext_Click;
}
But this has failed (The event is never raised)..

您可以像使用普通按钮事件处理程序一样使用它们,例如:
Html:
Code:
您可以使用命令参数来找出单击了哪个按钮。
希望这有帮助。
You can use them in the same way you would use a normal button event handler eg:
Html:
Code:
The you can use the command argument to find out which button was clicked.
Hope this helps.
我建议使用中继器的 ItemCommand 事件。不过,您仍然需要将命令添加到按钮中。像这样:
I would suggest using the ItemCommand event of the repeater. You still have to add the commands to your buttons though. Like this:
