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 displaying a money values in a gridview. Is possible to use inline code to set the decimal places to two? Would like to do it inline instead of in the C# code behind if possible. Database table column [Rate] is datatype money.

<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# " total monthly " + "$" + Eval("Rate") %>' ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
I have a page with a Textbox, a Button and a Label control. On Button_Click event , I store the value of Textbox in a variable called S using code behind.
I want to show the value of S in the Lable control using inline code but not using the code behind. ?

I've been using code behind files since day one. Now, I have this funky example that uses inline code. How do I use inline code that needs to be executed in Page_Load() while VS still gives me a code behind page? Do I remove the Page_Load event from code behind file?
View 2 Replies<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 have a simple user control (myControl.ascx) , in the myControl.ascx.cs file, I defined:
public string sUserName
{
get
{
return _sUserName;
}
set
{
_sUserName = value;
populateData();
}
}
In one of my aspx page, I use this control:

myNameSapce.Config.sType is a public value from a class, I just can't get that value for above inline code, is it possible to do that? Otherwise, I need go to the .cs file to do this: myControl1.sUserType = myNameSapce.Config.sType; But still hope I can do the inline code.
Here's the code I have.

I'm updating my old .aspx views with the new Razore view engine. I have a bunch of places where I have code like this:
<span class="vote-up<%= puzzle.UserVote == VoteType.Up ? "-selected" : "" %>">Vote Up</span>
Ideally I'd like to do this:
<span class="vote-up@{puzzle.UserVote == VoteType.Up ? "-selected" : ""}">Vote Up</span>
However there's two problems here:
vote-up@{puzzle.UserVote .... is not treating the @ symbol as a start of a code block @puzzle.UserVote == VoteType.Up looks at the first part @puzzle.UserVote as if it's supposed to render the value of the variable.
How can I call a .net method in inline code using a javascript variable?My code looks like this:
for ( var i = 0; i < numberIterations; i++ )
{
var result = <%# GetFilterTagURL( myArray[i].Value, false) %>;
//do stuff with result
}
This block is inside a javascript block; the GetFilterTagURL method is a a .net method and I want to pass the variable myArray[i].Value as the first parameter.
UPDATE:I guess that, as you say, I'll have to create a web service to achieve what I want.
I tried to assign the value of button text through the following syntax where MyValue is the public variable with the value "Checkout" in the code behind.
[Code]....
But it turned out that it displayed <%=MyValue%> instead of "Checkout". Yes of course I can still assign button text value in the code behind but just don't know if there is any other solutions to it.
EXISTING CODE:
<asp:HyperLink ID="HyperLinkG102" runat="server" Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) %>' Text='<%# Eval("L_GalleryName") %>' NavigateUrl='<%# String.Format(".... /findlink.aspx?linknum={0}", Eval("L_ID")) %>' Target="_blank" Font-Size="9"
ForeColor="Blue"></asp:HyperLink>
Is there anyway to put an OR conditional in the Visible text?
( Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) OR Visible='<%# (Convert.ToInt32(Eval("L_Rank")) != 0 ) %>' )
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 %>'>
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 RepliesWhat do you prefer? I watched a video about making a gridview and its function, and it only took about 6minutes, including the sort, delete, edit.
I don't know the difference of the two but I have made a registration form using code behind and i'm planning to make a gridview inline coding.
I'm wanting to insert some javascript in the body of a page using ClientScript.Register..() when a user returns to it (either by back button or on link click). When I use the back button the inline server script is never hit in debug. Any way to get the server to evaluate the code every single time the user is directed to that page.

"); } %>
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:

The errors are:
