I want to declare a variable in such a way that I can access that particular variable and its value in all the asp pages in the project. Can anyone tell me how to declare a variable in C# such that it has project-wide scope?
View 8 RepliesI am looking for differences between those 3 ways of using static class in asp.net application scope.
Will all of these point to the same class?
Which one is preferable >object< defined declaratively inside global.asax or static class ?
examples:
<object runat="server" scope="application" class="classname" ID="objID"></object>
VS
public static class classname {}
VS
Application("a") = new classname();
want to make sure I am not assuming something foolish here, when implementing the singleton pattern in an ASP .Net web application the static variable scope is only for the current user session, right? If a second user is accessing the site it is a different memory scope...?

I'm trying create unit testing for an existing website project (not web application project). I cannot access my under test classes unless I use accessor. However, if I use accessor, I have problem to initiate an object with passing arguments. I only want to create unit tetsing for App_Code. After searching web, and I found that I'd better to create a web application project using my current existing website project. From solution explorer, add new project ->using existing website. My questions is: what impact will have for my current website to create the new project? Should I just convert my current website to web application? If do that, will it cuase problems on my website?

so that all my content pages (.aspx) in my application could use default.master as their master page,
i read we do this so that we don't have to mention the MasterPageFile="~/default.master" everytime in all the .aspx content pages, but , my query is whenever i add a new .aspx page in my website from VS 2010, it dosen't automatically add MasterPageFile="~/default.master" to the Page header, am i missing something.

I have an application in which a user can choose from different (learning)groups. User has only access to registered groups. When the user enters the site, he can choose (in a dropdown) which group he wants to see, so the complete site filters content related to that group. So every controller needs to access this global "group" object.What is the best way to do this in ASP.NET MVC? I've thought about a BaseController or ActionFilters. Is there any other best practice?I've build a WebForms application and there I used a BasePage so that any other page has access to the group.

I have a ReportViewer (ver 10) that is rendering far wider than the box it's meant to display in. The problem is that the Parameters area is appearing much wider than the actual report area. If I put an "overflow: auto" in the div that contains the ReportViewer control, then I get a horizontal scrollbar at the bottom, but then in order to click the "View Report" button I have to scroll way over, thus moving the entire report.
Ideally I would like the Parameters area to stay stationary, but a horizontal scrollbar to appear on the report area so that it can be scrolled if necessary. What is the best way to go about doing this?
Here's what my control setup looks like now:
<div class="reportingFrame" style="text-align: center; width: 100%; overflow: auto">
<sam:ReportViewer ID="UiReportViewer" runat="server"
AsyncRendering="False"
ProcessingMode="Remote"
ShowExportControls="False"
ShowPrintButton="False"
ShowPromptAreaButton="False"
ShowRefreshButton="False"
SizeToReportContent="True"
Width="100%" />
</div>
Currently I'm looking at some jQuery tricks to reformat the output from the ReportViewer control into a better system
What is the recommended or usual way an ASP.net web application(in C# language) can store/access values that are needed accross the various pages in a website. For example a basic company website might need the company's name and other related information available to multiple pages. Where do I declare these variables/values and how do I access them. Coming from c++ application programming I would usually store such data in a Singleton class object.

How to do wide search and export the records to excel file ? im quite new in asp.net .
I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem).
What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected)
.
I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others).
All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where.
EDIT: Final solution looks as follows:
<asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton>
<asp:Panel ID="pnlCompany" runat="server" style="display:none">
<div>
<asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList>
<br/>
<asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" />
<asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" />
</div>
</asp:Panel>
<cc1:ModalPopupExtender ID="mpeCompany" runat="server"
TargetControlID="lnkCompany" PopupControlID="pnlCompany"
BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo"
DropShadow="true" PopupDragHandleControlID="pnlCompany" />
</EditItemTemplate>
</asp:TemplateField>
And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView:
Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs)
Dim intRow As Integer
Dim intVal As Integer
RestoreFromSessionVariables()
Select Case e.CommandName
Case "SelectCO"
intRow = grdIDCostLabor.EditIndex
Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList)
intVal = ddlCo.SelectedValue
lstIDLabor(intRow).CompanyID = intVal
lstIDLabor(intRow).Company = Company.Read(intVal)
Case Else
'
End Select
MakeSessionVariables()
BindGrids()
End Sub
can I change an aspx file name site wide. i.e. every instant of it any where in the site?
View 4 RepliesI have a multiple database operation, Have three tables (MSsql) and need to delete one row in each table in one operation, one after another. (Three functions, three rows of code). Everything is working as it should be, recently I was advised to use a transaction scope, which should guarantee the safety of deletion from all 3 tables together.
Here is my new code:
[Code]....
Locally all worked just fine, the transaction scope worked well, but when I have uploaded my application to my hosting server, I got an error of: The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025).I talked with the host support, they tried to do something, then I got this error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
After a 2 days, They have contacted me, they said it is not possible to disable some restriction, that will allow an access to this operation, because I'm using shared hosting, and I need to upgrade my plan to VPS. VPS is a very expensive for me, and I can't afford it, What I'm looking is a some similar way of doing the same operation as transaction scope do, that may work at my hosting, At least I would like to try something else. Is there any additional way for the transaction scope?
In this case I have a system where a user logs in, they get a dashboard and they can see all their related projects. The user can click on the project and open it. (ie /View/79) The problem the user can also just type /View/68 which they are not supposed to be able to view.
Obviously I am aware of how to filter my data, but this application has many many lists of data and it all needs to be scoped to data that user has been allowed to see. I can insert a plethora of joins and wheres in all my queries but.. it's a lot of work and a bit convoluted.So I was wondering what strategies other had used for filtering data based on the user scope.One approach I was thinking of was to extend my user-role-permission model so "permissions" could be assigned to various entitites (like projects). This way, rather than doing a series of joins etc to see confirm a user has been assigned to a project, my join is just onto the EntityPermission table to confirm the user has PermissionX (like: CanView) on that entity. I could either maintain a seperate M2M table for each entity i need to restrict or something a bit more general (but without referential integrity).
Here 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?
