ASP.NET - Getting the object inside Repeater ItemTemplate with/without Eval
I am new to Repeater and DataBinding and I need help using it.
In PageLoad, I have
var photos = from p in MyDataContext.Photos
select new {
p,
Url = p.GetImageUrl()
};
repeat开发者_如何转开发er1.DataSource = photos;
repeater1.DataBind();
In the Repeater control, I have
<ItemTemplate>
<% Photo p = (Photo) Eval("p"); %> <!-- Apparently I can't do this -->
...
<asp:TextBox runat="server" ID="txtTime" Text='<%= p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss") %>' />
...
</ItemTemplate>
But that is wrong.
What I need is to get the Photo object in ItemTemplate so I can do things with it (eg. to display the time as in the second line in ItemTemplate above). Is it even possible to do this in a Repeater?
Could someone point me to the right direction?
Thank you in advance!
Try something like this In the onDatabound event
if (e.Item.ItemType = ListItemType.Item)
{
photo p = (photo)e.DataItem;
Textbox txtTime = (Textbox)e.Item.FindControl("txtTime");
txtTime.text = (p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss"));
}
Edit -
Sorry, I didn't see the extra Url there. I looks like you might have to create a small class or struct.
See this Stackoverflow link for a hack workaround.
Paul Suart's post in that thread made a valid point.
Have you tried just:
<%# Eval("p") %>
instead of
<% Photo p = (Photo) Eval("p"); %>
I use an alternative method. In my "Register" I import the object class:
<%@ Import Namespace="Test.Test.TO" %>
With this It's possible use your object...
Next, I created an object the same type I want to bound in my codebehind, global variable...
public Test test;
In my Repeater inside ItemTemplete:
<span style="display: none;"> <%# test = (Test)Container.DataItem %> </span>
Now, you can use all object's properties, inclusive ToString to format with culture...
Sorry for my english.
