How do i set the label's text depending on the data field value. e.g. if it's proper datetime value then display it, otherwise display "unknown". Please notice that it's inline C# code
Code:
Text='<%# DateTime.TryParse(Eval("MyDate"), out DateTime.Parse("1/1/1753")) == true ? Eval("MyDate") : "unknown" %>'
When writing inline code in an .aspx file and some lines down closing a statement with <% } %>, Visual Studio tries to be nice but messes it up by rewriting it all. Is there any way of turning this rewriting off, but only for inline code?
View 2 RepliesThe inline code
<% for (int i = 0; i < ThumbnailList.Items.Count; i++)
{ Response.Write("thumbnailViews[" + i.ToString() + "] = $find('" +
ThumbnailList.Items[i].FindControl("ThumbnailView").ClientID + "');
"); } %>
produces a bunch of compile time errors in Visual Studio 2008 - although it works fine.
But this seems to be the exact way inline code should be added, at least according to this MS help file:
[URL]
The errors are:
expected expression (at "<%")
expected ';' (at "int i")
expected ')' (at ThumbnailList.Items.Count;
expected ';' (at " i++)")
I have done a

at the top of the file.

View 2 RepliesI have the following date in string format "2011-29-01 12:00 am" . Now I am trying to convert that to datetime format with the following code:
DateTime.TryParse(dateTime, out dt);
But I am alwayws getting dt as {1/1/0001 12:00:00 AM} , Can you tell me why ? and how can I convert that string to date.
EDIT:
I just saw everybody mentioned to use format argument. I will mention now that I can't use the format parameter as I have some setting to select the custom dateformat what user wants, and based on that user is able to get the date in textbox in that format automatically via jQuery datepicker.
How can I achieve the desired effect?
Here's the code:
<% if(!String.IsNullOrEmpty(%><%#Eval(Container.DataItem,"OrderXml");%><%)){ %>
etc., which is placed inside of an ItemTemplate inside of a TemplateColumn. In the CodeBehind page I will bind a value to the OrderXml field, which occasionally is NULL.
Unfortunately I get compilation errors.

I am building an MVC 2 web app, where I want to display information about something (the parent) as well as child details which are displayed as rows (children have a many to one relationship to the parent).I have implemented AJAX in MVC before using Ajax.BeginForm and partial views Using this method - with minor changes for MVC 2 release.
I want to add the ability to edit child rows inline using ajax, but I would like to know how others implement this. Are there facilities in MVC that can do this?

Is it possible to do things in a PHPish way in ASP.Net? I've seen <%= %> but I've tried it and couldn't get it to work. The PHPish equivalent of what I want to do is
<script src="<?php echo ResolveUrl("jquery/js/jquery.js"); ?>"></script>
I've got a repeater on my asp.net (VB):
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Question_Number") %>' />
<%#Eval("Question_Desc")%>
Now what I want to do is, check a value that I haven't used called "Question_Type" which could be = 1, 2 or 3 depending if it is multiple choice, short answer, etc. I have tried this:
<%
if Eval("Question_type") = 1 then
Response.Write(" <asp:RadioButton runat=""server"">test1</asp:RadioButton>")
Response.Write(" <asp:RadioButton runat=""server"">test2</asp:RadioButton>")
Response.Write(" <asp:RadioButton runat=""server"">test3</asp:RadioButton>")
end if
%>
and I get this error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. HOW can I use this value in a if statement?
I've got a bit of code that I started to manage, and it's begun to fail due to some data missing in the database. This case could happen in the future, so I'd like to gracefully handle the nulls in the front end. Here's the current code:
<asp:DropDownList ID="ddlContact" runat="server"
SelectedIndex='<%# Bind("contactInfo") == null ? "" : Bind("contactInfo") %>'>
It doesn't seem to have any affect on it, and the page still throws a NullReferenceException. It needs to be a Bind() due to the two-way data binding requirement, so I can't use Eval(). I've tried to use the null-coallescing operator "??" but that gives me a compilation error stating that Bind() does not exist in the current context. That could would look like this:
<asp:DropDownList ID="ddlContact" runat="server"
SelectedIndex='<%# Bind("contactInfo") ?? string.Empty %>'>

<form id="form1" runat="server" method="post" action="Default.aspx?id=<%= ID %>" >
Ok, it is very ugly and I wouldn't have ever tried it myself. It came up in some code that was written years ago but had been working up until this weekend after a bunch of updates were installed on a client's web server where the code is hosted.
The actual result of this is the following html:
<form name="form1" method="post" action="Default.aspx?id=<%= ID %>" id="form1">
The url ends up like this:
http://localhost:6735/Default.aspx?id=<%= ID %>
Which as you can see, demonstrates that the "<" symbol is being encoded before ASP.NET actually processes the page. It seems strange to me as I thought that even though it is not pretty by any means, it should work. I'm confused.
To make matters worse, the client insists that it is a bug in IE since it appears to work in Firefox. In fact, it is broken in Firefox as well, except for some reason Firefox treats it as a 0.
Any ideas on why this happens and how to fix it easily? Everything I try to render within the server control ends up getting escaped.
Edit
Ok, I found a "fix"
<form id="form1" runat="server" method="post" action='<%# String.Format("Default.aspx?id={0}", 5) %>' >
But that requires me to call DataBind which is adding more of a hack to the original hack. Guess if nobody thinks of anything else I'll have to go with that.
I am trying to do an inline IF statement inside a asp:Repeater control to add a class to the first item, but I can't quite seem to figure it out.
Basically the code I have right now that is not working but should give an idea of what I'm "trying" to do looks like this.
<asp:Repeater ID="rptrTabRepeater" runat="server">
<ItemTemplate>
<div class="tab <%= If Container.ItemIndex = 0 Then %>highlight<% End If%>">
'Other stuff here
</div>
</ItemTemplate>
</asp:Repeater>
I have tried using the OnItemDataBound event but the delegate interface cannot return a value. If I'm going to do anything from a code-behind function really it would just need to be an "echo" kind of function which I wasn't quite sure how to get the item index in a code behind function. If I could do something inline like my example that would be the best solution for me.

Compiler Error Message: BC30201: Expression expected.

View 2 RepliesFor reasons that are probably not worth mentioning in this post, I have decided to stop using ASP.NET controls and simply use regular HTML controls for my .aspx pages. As such, to dynamically generate HTML, I use c# inline to the .aspx to do what I need to do.
For example: this .aspx snippet shows how I am dynamically creating a <select> element where the <option> elements are driven by looping through a generic list of objects.
<select name="s">
<option value="-9999">Select an entity...</option>
<% foreach (MyEntity e in this.MyEntities)
{%>
<option <% if (MyEntityInScope.ID == e.ID)
{ %>selected<%} %> value="<%= e.ID %>">
<%= e.Name%></option>
<%} %>
</select>
Functionality-wise, I prefer this method of creating HTML (I feel more in control of how the HTML is generated vs ASP controls). However, syntactically (and visually), I think it's cumbersome (and ugly).
Is there a "better" way (another syntax) to dynamically generate HTML w/out resorting to using ASP.NET controls?
