这是我的ASP转发器代码
<asp:repeater id="filterTable" runat="server">
<HeaderTemplate>
<br/><br/><br/>
<div class="table-responsive">
<table width="100%" cellspacing="0" id="table_odd" class="quickordertable table table-bordered table-striped table-condensed grid-table">
<tr>
<th style="width: 80px">
Details
</th>
<th style="width: 80px">
Filter
</th>
<th style="width: 30px">
Qty
</th>
<th style="width: 60px">
Include In Order
</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%#Eval("Details")%></td>
<td><%#Eval("FilterType")%></td>
<td><%#Eval("Qty")%></td>
<td><asp:CheckBox ID="orderPartNumber" Checked="true" runat="server"/><asp:HiddenField ID="hiddenPartNumber" Value ='<%#Eval("PartNumber")%>'></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</div>
</FooterTemplate>
</asp:Repeater>
我有一个ASP ItemTemplate,其字段为<%#Eval("GenuineOnly")%>
如果字段GenuineOnly
包含值,(或者不是Null)那么我想显示此代码
<td>GENUINE ONLY</td>
否则我想显示此代码
<td><asp:CheckBox ID="orderPartNumber" runat="server"/><asp:HiddenField ID="hiddenPartNumber" Value ='<%#Eval("PartNumber")%>'></td>
我尝试过多种不同的方式,但似乎无法正确理解语法!任何帮助将不胜感激。

您可以使用以下方式实现此目的:
<td>
<asp:Panel runat="server" Visible='<%#Eval("GenuineOnly").ToString().Length > 0 %>'>
<asp:CheckBox ID="orderPartNumber" Checked="true" runat="server" />
<asp:HiddenField runat="server" ID="hiddenPartNumber" Value='<%#Eval("PartNumber")%>' />
</asp:Panel>
<asp:Panel runat="server" Visible='<%#Eval("GenuineOnly").ToString().Length == 0 %>'>
GENUINE ONLY
</asp:Panel>
</td>

我假设您可以根据需要添加Table / Td。
<asp:Repeater ID="rptr" runat="server" OnItemDataBound="rptr_ItemDataBound">
<ItemTemplate>
<asp:Label ID="lblGenuineOnly" runat="server" Text='<%#Eval("GenuineOnly") %>' />
<asp:CheckBox ID="orderPartNumber" runat="server"/>
<asp:HiddenField ID="hiddenPartNumber" Value ='<%#Eval("PartNumber")%>' runat="server" />
</ItemTemplate>
背后的代码
protected void rptr_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
Label lblPartNumber = (Label)e.Item.FindControl("lblGenuineOnly");
CheckBox chkPart = (CheckBox)e.Item.FindControl("orderPartNumber");
if (string.IsNullOrEmpty(lblPartNumber.Text.Trim())) {
//Display GENUINE ONLY in any label like lblPartNumber.Text = "GENUINE ONLY"
chkPart.Visible = false;
}
else
{
chkPart.Visible = true;
}
}
