DataTable and ASP.NET Repeater
提问by DMckendrick
I am binding a DataTable to a repeater. However when I run my aspx page it is not evaluating the Eval statements and displaying them on the page as
我正在将 DataTable 绑定到中继器。但是，当我运行我的 aspx 页面时，它不会评估 Eval 语句并将它们显示在页面上
<<%# Eval("Name").ToString() %> Posted by: <<%# Eval("UserName").ToString() %>
<<%# Eval("Name").ToString() %> Posted by: <<%# Eval("UserName").ToString() %>
<<%# Eval("Name").ToString() %> Posted by: <<%# Eval("UserName").ToString() %>
It is also breaking it down to 3 rows. Which is also not what I had expected. I thought it would display as spans normally would
它还将其分解为 3 行。这也不是我所期望的。我认为它会显示为跨度通常会
I have taken out the .ToString to check if it was that causing the issue. But it was not.
我已经取出 .ToString 来检查是否是导致问题的原因。但事实并非如此。
Below is my Repeater
下面是我的中继器
<asp:Repeater ID="First" runat="server">
<ItemTemplate>
<div class="ItemDiv">
<span class="ItemLeft"></span>
<span class="ItemCentre">
<asp:Label ID="Name" runat="server" Text='<<%# Eval("Name").ToString() %>'></asp:Label>
</span>
<span class="ItemRight">
<asp:Label ID="UserName" runat="server" Text='<<%# Eval("UserName").ToString() %>'></asp:Label>
</span>
</div>
</ItemTemplate>
</asp:Repeater>
The code to bind is the following:
绑定的代码如下：
public void dataLoad()
{
DataTable Data = loadData(1,1,1);
if (Data.Rows.Count < 10)
{
// Only populate the data from datatable
First.DataSource = Data;
First.DataBind();
Second.Visible = false;
noData.Visible = true;
}
I have changed some of the names in the above example
我已经更改了上面示例中的一些名称
In the Debug information I can see that my DataTable is using the correct column names, and that these match my eval statements.
在调试信息中，我可以看到我的 DataTable 使用了正确的列名，并且这些与我的 eval 语句匹配。
I know I have created this in a rather strange way, from what I have read, and researched online it is more common to use a table rather than Divs/or Spans for this. So I am aware that that may be the problem at its heart.
我知道我以一种相当奇怪的方式创建了这个，从我阅读的内容和在线研究来看，为此使用表格而不是 Divs/或 Span 更为常见。所以我知道这可能是问题的核心。
I cannot see why it would be any different.
我不明白为什么会有所不同。

Remove the <<from your eval statements. It should be:
<<从您的 eval 语句中删除。它应该是：
<div class="ItemDiv">
<span class="ItemLeft"></span>
<span class="ItemCentre">
<asp:Label ID="Name" runat="server" Text='<%# Eval("Name").ToString() %>'></asp:Label>
</span>
<span class="ItemRight">
<asp:Label ID="UserName" runat="server" Text='<%# Eval("UserName").ToString() %>'></asp:Label>
</span>
</div>
