我只想在具有 OnItemCommand 的中继器中触发 LinkButton。但是该页面确实会发回。这是我的代码:
<asp:UpdatePanel ID="recommendedAdvertsUpPnl" runat="server">
<ContentTemplate>
<div class="tagList">
<asp:Label ID="lbListBookType" runat="server"></asp:Label>
<asp:Repeater ID="rpRecommendedAdvertFacultyList" runat="server" OnItemDataBound="rpRecommendedAdvertFacultyList_ItemDataBound" OnItemCommand="rpRecommendedAdvertFacultyList_ItemCommand">
<HeaderTemplate></HeaderTemplate>
<ItemTemplate>
<asp:LinkButton ID="lbtnAdvertFaculty" runat="server" CommandArgument='<%#Eval("facultyId") %>' CommandName="selectFaculty" CssClass="advertFacultySelection"></asp:LinkButton>
</ItemTemplate>
<FooterTemplate></FooterTemplate>
</asp:Repeater>
</div>
<div class="RecommendedAdverts_List">
<asp:Repeater ID="rpRecommendedAdvertList" runat="server" OnItemDataBound="rpRecommendedAdvertList_ItemDataBound">
<HeaderTemplate>
<ul class="content_recommended">
</HeaderTemplate>
<ItemTemplate>
<%# Container.ItemIndex % 4 == 0 ? "<li><div class=advertContainer>": String.Empty%>
<div class="advertPanel">
<div class="rAdvPanel">
<div class="advertPic"><asp:Panel ID="pnlRecAdvertPic" runat="server"></asp:Panel></div>
<div class="advertInfoPanel">
<a href="../../IlanDetay/<%#Eval("Book.name") %>/<%#Eval("id") %>"><%#Eval("Book.Name")%></a> <br />
<%#Eval("Book.Authors")%><br />
<%#Eval("Price")%> TL<br />
</div>
</div>
</div>
<%# Container.ItemIndex % 4 == 3 ? "</div></li>": String.Empty%>
</ItemTemplate>
<FooterTemplate>
</div></li>
</ul>
</FooterTemplate>
</asp:Repeater>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="rpRecommendedAdvertFacultyList" EventName="ItemCommand" />
</Triggers>
</asp:UpdatePanel>
除了触发没有问题。这是我的服务器端代码:
protected void rpRecommendedAdvertFacultyList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
AdvertFacultyInfo item = (AdvertFacultyInfo)e.Item.DataItem;
LinkButton lbtnAdvertFaculty = (LinkButton)e.Item.FindControl("lbtnAdvertFaculty");
lbtnAdvertFaculty.Text = item.Faculty.name;
}
}
protected void rpRecommendedAdvertFacultyList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
switch (e.CommandName)
{
case "selectFaculty":
List<AdvertFacultyInfo> advFacultyInfoList = EntitiyProvider.GetAdvertFacultyInfoListByFacultyId(Convert.ToInt32(e.CommandArgument));
List<Advert> selectedList = new List<Advert>();
foreach (AdvertFacultyInfo item in advFacultyInfoList)
{
Advert currentAdv = this.recommendedAdvertList.FirstOrDefault(i => i.id == item.advertId);
if ( currentAdv != null)
{
selectedList.Add(currentAdv);
}
}
rpRecommendedAdvertList.DataSource = selectedList;
rpRecommendedAdvertList.DataBind();
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "temp", "<script type='text/javascript'>$('.content_recommended').quickPager()</script>", false);
break;
default:
break;
}
}
我也试过这段代码:但它给出了像lbtnAdvertFaculty找不到的错误
<asp:AsyncPostBackTrigger ControlID="lbtnAdvertFaculty" EventName="Click" />
我研究了很多有关此问题的文档,但找不到有用的示例和解决方案。
此致。
