我有一个转发器,我正在尝试访问其中的标签。这是我的方法:
protected void ButtonlarıTemizle()
{
int n = 0;
foreach (RepeaterItem item in Repeater1.Items)
{
n++;
Label lbl = item.FindControl("lblApproved") as Label;
Button btn = item.FindControl("btnAssignApproved") as Button;
if (lbl.Text.Equals("Satışa Dönmüştür"))
{
btn.Visible = false;
lbl.ForeColor = System.Drawing.Color.Blue;
}
}
Response.Write("<script lang='JavaScript'>alert('"+n+"');</script>");
}
我可以访问内部转发器,但问题是:我无法访问转发器的最后一项。我把'n'变量控制到我在foreach循环内转了多少次,我看到n总是给出项数的-1。例如,如果我在转发器中有3个项目,则n为2,如果转发器中有1个项目,则n为0.我在这里做错了什么?
编辑:我正在写我的.aspx页面,因为它要求
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="EntityDataSourceTeklifler" OnItemCommand="Repeater1_ItemCommand">
<ItemTemplate>
<div class="panel panel-primary">
<div class="panel-body">
<strong>Teklif No.</strong> <%#Eval("TeklifId") %><br />
<strong>Teklif Tarihi:</strong> <%#Eval("TeklifTarih") %><br />
<strong>Teklifi Hazırlayan:</strong> <%#Eval("Name") %> <%#Eval("Surname") %><br />
<strong>Firma Adı:</strong> <%#Eval("FirmaAdi") %><br />
<strong>Ürünler:</strong><br />
<%#Eval("TeklifSiparis") %>
<strong>Genel Toplam:</strong> <%#Eval("TeklifTutar") %>$<br />
<strong>Not:</strong><br />
<%#Eval("TeklifNot") %><br />
<strong>Teklif Durumu:</strong> <asp:Label ForeColor="Red" ID="lblApproved" runat="server" Text='<%# CheckIfApproved(Convert.ToBoolean(Eval("Approved"))) %>'></asp:Label><br /><br />
<asp:Button ID="btnAssignApproved" runat="server" Text="Satışa Döndü Olarak İşaretle" CssClass="btn btn-primary" CommandName="Done" CommandArgument='<%# Eval("TeklifId") %>' />
</div>
</div>
</ItemTemplate>
</asp:Repeater>
答案 0 :(得分:1)
我不确定为什么你明确地调用另一种方法,但你在做什么可以在转发器控制的ItemDataBound
事件中轻松完成: -
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound"
然后像这样处理它: -
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item)
{
Label lbl = e.Item.FindControl("lblApproved") as Label;
Button btn = e.Item.FindControl("btnAssignApproved") as Button;
if (lbl.Text.Equals("Satışa Dönmüştür"))
{
btn.Visible = false;
lbl.ForeColor = System.Drawing.Color.Blue;
}
}
}
请注意,您的转发器项目无需循环。每个项目受限时,将对每个项目触发Repeater ItemDataBound
事件。此外,如果您希望count
只是在此方法之外声明一个变量,并在此事件中增加它。
