中继器的ItemDataBound不会影响某些值
本文关键字:影响 ItemDataBound 中继器 | 更新日期: 2023-09-27 18:26:58
我有一个中继器,里面有一些标签和按钮。这是我的.aspx:
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="EntityDataSourceTeklifler" OnItemCommand="Repeater1_ItemCommand" OnItemDataBound="Repeater1_ItemDataBound">
<ItemTemplate>
<div class="panel panel-primary">
<div class="panel-body">
<strong>Teklif No.</strong> <asp:Label ID="lblTeklifNo" runat="server" Text='<%#Eval("TeklifId") %>'></asp:Label><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" CommandArgument='<%# Eval("TeklifId") %>' />
</div>
</div>
</ItemTemplate>
</asp:Repeater>
还有我的代码头:
protected string CheckIfApproved(bool isApproved)
{
string result;
if (isApproved)
{
result = "Satışa Dönmüştür";
}
else
{
result = "Satışa Dönmemiştir";
}
return result;
}
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
string teklifId = e.CommandArgument.ToString();
TeklifTable teklif = entity.TeklifTable.Where(t => t.TeklifId == teklifId).FirstOrDefault();
teklif.Approved = true;
entity.SaveChanges();
Page_Load(null, EventArgs.Empty);
}
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;
}
else
{
lbl.ForeColor = System.Drawing.Color.Purple;
}
}
}
正如你所看到的,我的中继器根据数据库的布尔属性"Approved"更改标签颜色和按钮可见性。点击按钮即可更改已批准的属性,此处没有任何问题。我正在检查approved值是真是假,并根据它更改标签。最后,ItemDataBound方法根据checkIfApproved方法中更改的标签更改标签颜色和按钮可见性。
现在,这是我的问题。正如你所看到的,我在.aspx中将默认标签颜色定义为红色。这应该更改为蓝色或紫色,但某些值保持为红色。也就是说"Repeater1_ItemDataBound"方法不会影响某些值。这里还有一个有趣的点:中继器的第一个项目按照我的意愿生效,并根据标签文本显示为蓝色或紫色,但第二个项目变为红色。这意味着第二个项不会受到这种方法的影响。第三项生效,第四项不生效。事情是这样的。有什么想法吗?
代码的问题是,您只检查该项是否为Item
类型,但中继器控制项由Item
和AlternatingItem
组成,即每个交替项行为都属于ListItemType
的AlternatingItem
。
只需在ItemDataBound
事件中添加以下行:-
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//your code here
}
}
