C# - Declare And Create Variable In Code Behind?
Jul 27, 2010Here are 3 scenarios:
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v;
protected void Page_Load(object sender, EventArgs e){
if (!Page.IsPostBack) v= new Variable();
....
}
}
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v = new Variable();
protected void Page_Load(object sender, EventArgs e){
}
}
namespace NS
{
public partial class A: System.Web.UI.UserControl
private Variable v;
protected void Page_Load(object sender, EventArgs e){
v = new Variable();
}
}
When does the variable "v" gets created every time for the 2nd scenario? Is the 2st scenario is equivalent to the 3rd one?
.net: Use Javascript Variable Into .net Method In Inline Code?
Mar 28, 2011How 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.

C# - Hidden Variable Vs Server Variable Accessing On Client Side In Javascript
Jul 14, 2010I'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?

View 1 RepliesTo Reach A Variable From A Different Code-block Expression Than The Block Where The Variable Was Declared ?
Oct 25, 2010I have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?

View 1 RepliesC# - Using Variable From Code Behind?
Oct 4, 2010I'm having a bit of difficulty setting a variable from the code behind and utilising it in the ASP.NET page (setting it as the value inside a textbox). My webpage simply errors and says it does not exist in the current context. The variable is declared and set all in the Page_Load method.
Here is the relevant ASP.NET code. I assume you will not need to see the code behind, as I have tested outputting the variable via the codebehind (using Response.Write) and that works fine.
<asp:TemplateField HeaderText="Initial Path"
SortExpression="Initial_Path">
<EditItemTemplate>
<asp:TextBox ID="TextBox6" runat="server"
[Code]....
What's not working is just the <%= initialpath %> in the ASP form. It simply just doesn't show anything, like the variable is assigned nothing

View 2 RepliesMVC :: Create Session Variable At Logon?
Dec 3, 2010I'm building an application using MVC3 RC and I'm trying to add a session variable as soon as anyone logs on. The variable is an int which is retrieved from a database using User.Identity.Name to retrieve the relevant database record.
I'm using the MS AccountController and tried adding the session variable immediately after the line:
FormsService.SignIn(model.UserName, model.RememberMe);
Although this is the point at which the logon is validated the User.Identity.Name is still showing as null when I try to get it immediately after.
Does anyone know when User.Identity.Name is actually populated in the session and how I can intervene to grab it at that point?
