View 2 RepliesI have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
How can this be done? Does this exclude the UpdatePanel functionality when it's done?

View 2 RepliesI am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.
Is there any way to access that class directly from the aspx page?
I know that i can make a method like:
width="<%= getWidthSize() %>"
and inside the aspx.cs to define this method to take the size from that static class.
But i am asking if this could be directly managed from the web aspx page...?
Basic question - is it possible to access the current Page from a static class in ASP.NET?
I am thinking no, as google turns up no results.
I created one method in master page, I want to use that method in some other page(Child or Content page).I tried this method but No luck, it's not working in Master Page:
public partial class TestMaster : System.Web.UI.MasterPage
{
public void XXXX()
{
}
}
I'm trying to call this method in child page like
TestMaster MyMasterPage = (TestMaster )this.Master;
MyMasterPage.
my MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..
private void ChangePageTitle(string PageTitle)
{
Label lblPageTitle = (Label)Master.FindControl("lblPageTitle");
lblPageTitle.Text = PageTitle;
}
Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?
I have a class and call class A method by creating class A object
unlike this call Class B method by using class B object
Code is here below
class A {
public void A1() {
Console.WriteLine("I am from Class A");
}
}
class B {
public void B1() {
Console.WriteLine("I am from Class B");

I'm using jQuery and setInterval method in my asp.net web application.
I call the webservice every 5 seconds in order to check for DB changes. When i see a change, i want to change the photo of the linkButton that located on the master page, but i can to that due to static constrains.
An object reference is required for the non-static field, method, or property 'System.Web.UI.Page.Master.get'
my c# code is:
[WebMethod()]
public static bool checkDBChange(string userId) {
DBConnection dbConnection = new DBConnection();
if (dbConnection.isChanged(userId)) {
((Site1)Master).SetImageUrl = "~/Icons/a.ico";
}
return false;
}
The SetImageUrl is a setter in my master page that sets the new url to the linkButton. How I can implement it?
While understanding the basic concept of inheritance in internet, i came across a piece of code.
I've seen many people using public static void main().Why dont they simply use public void main() ??What's the advantage of using static here ?
Public class BaseClass {
Public BaseClass () {
Console.WriteLine ("Base Class Constructor executed");
} Public void Write () {
Console.WriteLine ("Write method in Base Class executed");

I have a Solution in which i m using Gridview which stores image inside it. Every time when user uploads images and clicked on button, image get inserted into Gridview.
But every time user hits on button page get postback,so to avoid this i used web method which is get called when user hits on button (html button). But when i m trying to bind gridview in this method.It is not get accessed .
how i access this gridview inside web method? Why Web methods are always static?Is there any other way to do this?
So i was thinking on using an image and a literal control. The questions i have is
1)Is there a better control to use than literal?I am using it because the text would have html and i must render it.
2)How i will achieve putting text beside the picture(the site uses a <strong> as i see in firebug but i cannot view the css and after that everything is simple text and some <br> )?
If i put the literal beside with <strong> and have a specific div size will the text automatically go below when reach the div limit?I'm asking because it will be html so i don't know if it(html) can surpass the main div container.
How can access html control from webmethod
