Move Inline Code To Codebehind?

Jan 29, 2010

I have a project made with inline code. How can I most quickly move inline code to codebehind for each webform? First, how can I add a codebehind page aspx.c or aspx.vb to one that doesn't have one?

Place DataBinding Inline Code Inside Of Inline C# Code?

Jul 28, 2010

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.

Repeater Controls' ItemDataBound - Handle Inline Or Codebehind?

Oct 12, 2010

Are there any differences between coding row-specific stuff inline within the repeater's template and doing so in the codebehind file in ItemDataBound?

EDIT: Re: differences - I think we're all agreed it makes for markup that's nasty to read/maintain :) I was thinking of performance benefits.

How To Move A List To Codebehind

Jan 25, 2011

I have some markup on a page which I need to move to a code behind and I'm not quite sure how to do it

An example is this

<asp:DropDownList ID="YearList" runat="server">
<asp:ListItem Value="1940" Title="1940" />
<asp:ListItem Value="1950" Title="1950" />
<asp:ListItem Value="1960" Title="1960" />
<asp:ListItem Value="1970" Title="1970" />

Would the codebehind become

With YearList
.Value(0)="1940"
.Text(0)="1940"
End With

Forms Data Controls :: How To Move A Detailsview Sqldatasource To Codebehind

Apr 5, 2010

I have working code similar to the following in my Detailsview:

<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:DATABASE %>"
SelectCommand="SELECT Id, PracticeId, FirstName, LastName, Notes FROM Providers WHERE Id=@Id"
UpdateCommand="UPDATE Providers SET
PracticeId = @PracticeId,
FirstName = @FirstName,
LastName = @LastName,
Notes = @Notes
WHERE Id = @Id"
InsertCommand="INSERT INTO Providers (
PracticeId, FirstName, LastName, Notes
) VALUES (
@PracticeId, @FirstName, @LastName, @Notes)">
<SelectParameters>
<asp:QueryStringParameter Name="Id" QueryStringField="Id" Type="String" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="Id" Type="Int32" />
<asp:Parameter Name="PracticeId" Type="Int32" />
<asp:Parameter Name="FirstName" Type="String" />
<asp:Parameter Name="LastName" Type="String" />
<asp:Parameter Name="Notes" Type="String" />
</UpdateParameters>
<DeleteParameters>
<asp:Parameter Name="Id" Type="Int32" />
</DeleteParameters>
</asp:SqlDataSource>

I would like to move all of this to codebehind so it's easier to work with programmatically. For instance the PracticeId is a selection from a dropdownlist that is populated from another table... i need to determine what the current selection is first so i can display the record / bind properly.

Inline Code In A Server Control?

May 24, 2010

<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.

Assign Value To User Control Using Inline Code

Jan 20, 2010

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:

[Code]....

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.

How To Use If Statements With Razor And Inline Code Blocks

Jan 22, 2011

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.

.net: Use Javascript Variable Into .net Method In Inline Code?

Mar 28, 2011

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.

Web Forms :: Inline Code To Assign Value To Button Text

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.

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.

Forms Data Controls :: Put OR In Conditional Inline Code?

Is there anyway to put an OR conditional in the Visible text?
