View 9 RepliesWeb Forms :: How To Reference A Master Page Control From A Static Class
Feb 15, 2011my 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?
Web Forms :: Deleting A Folder Clears Static String?
Jul 14, 2010i have an a web app where i have a .cs file and .aspx file ..I have a function called display which calls the .cs file and use the static connecting sting to display data.I have a log folder which is just used by update function.No connecting with display.
The app runs completely fine when nothing is being done.But when i delete the log foler manually and press refresh button (which calls the display method) then the static string value is set to null.It seems very wierd.I kept a break point at the .cs file declared static varaible.Its declared in class so its value is for the whole class.
public class mon
{
static string constr;
[code]...
It works completely fine (i mean not clearing the constr) until i delete a folder in the MONWeb1 directory.So what happens is that i delete a folder and when i press refresh button which instiante the class vairable.
It comes here.
public class mon
{
static string constr;
& makes it null .. (i had a watch on that variable).This is really very odd.
Web Forms :: Object Reference Is Required For Non-static Field / Method Or Property
May 7, 2015I'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?

View 1 RepliesC# - Where Does Static Variable Work In Page
Apr 26, 2010I had an interview today and every thing was going very good, but then an interviewer asked me a question Where Does Static Variable Work in C#- At Application Level or At Page Level.I was not very much clear about this answer as I only knew that static variables are stored on heap and I didn't knew anything about web related thing.
Then he tried to make me more clear by giving an example that in a page I am using static variable and three users are accessing the page one of the user updates the value of static variable, What value will be visible to remaining two users an old copy or the update will be reflected.

Intellisense/Reference To Static Class Object Lost
Jul 21, 2010We have a Static class that 's called CData in our asp.net c# app.It handles all the data layer CRUD functionality on our pages.
Problem is, were are losing the intellisense reference in our pages to it.For example: we would expect to type CData.(dot) and have a list of methods and properties available to us.
Nope. Not there.
I kind of thought it was because the file was getting too long at 3000 lines of code, since some other static classes were working ok.
So then I thought that I'd try wrapping the CData Class in a namespace. That worked, but of course I had to put an include statement of the top of each page that's using CDATA, also, now some of the other developers are getting errors in there pages complaining about missing methods that are in CDATA, but their pages are not seeing.
State Management :: Cache Vs Static Variable?
Sep 24, 2010I know the big difference, but one thing is confusing me. Cache works only on a single machine on webfarm and to make it globally we use Velocity or memcache.So is static does same, or is it already work globally ?
eg
Cache["someid"] = "value"; //this will only work on single machine cache,
static string abc = "value"; // will this work on single machine or globally ?

Configuration :: Static Variable Being Reset To Null By IIS?
Feb 3, 2011my asp.net app uses dynamic stylesheets. so each of my pages uses a pre_init method to load the relevant stylesheet. the stylesheet is the same for ALL users of the app.for each page load, i don't want to query the database to determine which stylesheet to use. therefore, I simply load the stylesheet from a STATIC variable that I store when the app starts.
works fine locally. however, on the production server the STATIC variable is reset to Null after about 5 minutes. why is that?? is there a better way for me to handle this? Should I change something in IIS? Should I change the methodolgoy I am using to retreive the stylesheet?
Each .aspx page includes:
[Code]....
BusinessLogic.Admin:

View 8 RepliesWeb Forms :: Reference Global.asax Variable In Page?
Apr 27, 2010I have a ASP.NET/C# web application. There is an object instantiated in the Global.asax that I'll call g_objVariable. What I would like to do is reference one of it's properties in the ASP.NET page itself, like this.
The g_objVariable's Prop1 value is: <%=AppNameSpace.Global.g_objVariable.Prop1.ToString()%>
I get it to see the reference, but it keeps telling me that due to it's protection level I can't access it. I have it set to 'internal static'. What would be the least level I could set it to, but still allow the page to access it?

Mar 22, 2010Aplogies if this has been discussed before but I couldn't find an answer.
I'm trying to use jquery/Ajax to access some webmethods in my codebehind. This is fine, but I would in my function like to reference a placeholder (phStory in the code below) on my page and also load a usercontrol into that placeholder.
Unfortunately I get the message: "An object reference is required for the non-static field, method, or property 'TestControls.phStory' " and similar for the usercontrol. Does anyone know how I can still access my placeholder and usercontrol from within this.
It has to be stati as it's a WebMethod but this then throws up these errors.

How To HttpContext.Current Work, Providing Context Appropriate State Off A Static Variable
Mar 31, 2010I've always wondered how you can access the correct state of the current http context via a static method:
HttpContext.Current.Session["foo"] = "bar";
In any other program, anywhere else, my initial assumption about working with a static accessor like this is that changing it will change it across all threads. Similarly, another thread running my change it on me while I am trying to use it.But HttpContext.Current does not behave like this. It provides the appropriate state for the given request, even through the static accessor.
State Management :: Keeping Application Variable Or Static Class For Global String?
Nov 18, 2010I need to keep a global variable throughout the whole time the user is at my site, but do I use Application or a static class? The string variable should store a region name and my site makes a few changes depending on which region that has been set.
I read that Application was mainly for classic ASP, but I also read that a static class cannot be instantiated at runtime (e.g. when the user has logged in).
So, have I got something wrong here and which solution do I use?
