View 1 RepliesI need little clarification regarding the Application Domain. As it has been said in the .net framework documentation "a process can have one or more application domain", Does it means There can be only one process in a machine dedicated for the .net application and whenever a new .net application gets executed, an application domain gets created in the above mentioned process?

View 1 RepliesI was under the impression till now that Global.asax is used for application level events and it's a common file for all users. Then what does Session_Start event does in this file. If we have to create user session varaibles then Is this the write place to create those? If someone can kindly clear my confusion on this file and it's methods.
View 5 RepliesI've been looking on the Internet for a fairly clear explanation of the different methods of registering javascript in an asp.net application. I think I have a basic understating of the difference between registerStartupScript and registerClientScriptBlock (the main difference being where in the form the script is inserted).I'm not sure I understand what the RegisterClientScriptInclude method does or when it is used. From what I can gather, it is used to register an external .js file. Does this then make any and all javascript functions in that file available to the aspx page it was registered on? For example, if it was registered in the onLoad event of a master page, would all pages using that master page be able to use the javascript functions in the .js file? What problems would arise when trying to use document.getElementById in this case, if any? Also, when it is necessary/advantageous to use multiple .js files and register them separately?
View 1 RepliesIt took me a while to realize the following, which was generated by VS after dragging and dropping the script file to a view file, does not work
[Code]....
However, the former works perfectly for another view file. I am wondering if any expert could shed some light on this.My current hunch is the correct path without using helper Url.Content() depends on a page's URl not where the view file is located.
var Dic = _db.Dictionaries.Single(m => m.int_DictionaryId == id);
var DicRef = Dic.DictionaryRefs.Where(m => m.int_DictionaryId == id);
The second one will make a database call or will it based on Dic?
i have i doubt. any body clarify this doubts. Find biggest character in a string. using ascii values.
View 3 RepliesMy understanding of Factory Method Pattern is (Correct me if i am wrong) Factory Method Pattern "Factory Method allow the client to delegates the product creation (Instance Creation) to the subclass". There are two situation in which we can go for creating Factory Method pattern.
(i) When the client is restricted to the product (Instance) creation.
(ii) There are multiple products available.But a decision to be made which product instance need to be returned. If you want to create Abstract Method pattern
You need to have abstract product Concrete Product Factory Method to return the appropriate product.
public enum ORMChoice
{
L2SQL,
EFM,
LS,
Sonic
}
//Abstract Product
public interface IProduct
{
void ProductTaken();
}
//Concrete Product
public class LinqtoSql : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken:LinqtoSql");
}
}
//concrete product
public class Subsonic : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken:Subsonic");
}
}
//concrete product
public class EntityFramework : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken:EntityFramework");
}
}
//concrete product
public class LightSpeed : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken :LightSpeed");
}
}
public class Creator
{
//Factory Method
public IProduct ReturnORTool(ORMChoice choice)
{
switch (choice)
{
case ORMChoice.EFM:return new EntityFramework();
break;
case ORMChoice.L2SQL:return new LinqtoSql();
break;
case ORMChoice.LS:return new LightSpeed();
break;
case ORMChoice.Sonic:return new Subsonic();
break;
default: return null;
}
}
}
**Client**
Button_Click()
{
Creator c = new Creator();
IProduct p = c.ReturnORTool(ORMChoice.L2SQL);
p.ProductTaken();
}
Is my understanding of Factory Method is correct?
I have followed your Nested level gridview and found it working, but i want add a button in the child element(from your example i will have a btn in Product grid and it should get contact_id (parent datakey value as well) ),as i need to update in database.

Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.
Recently I faced few interview questions.The interviewer asked the to give the detailed answer.1)Can we override a WCF service (Its is not OOPS overriding) ?.Explain the reason on either end. (WCF Related).2)Can we override Page events (Page_Load())?.Explain reason.(ASP.NET related).3)What is the primary responsibility of Pre_Init( page) event ,apart from user preference setting,skinning?4) Can we override Static methods.Explain the reason.(C# related)
View 1 RepliesI would like to show the title and the price of a movie in my Gridview. The title and price are properties from the class Movie and Movie is a property of the class CartItem. Here is the Code of my gridview
<asp:GridView ID="gvShoppingCart" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField DataField="Title" HeaderText="Title" />
<asp:BoundField DataField="Price" HeaderText="Price" />
</Columns>
</asp:GridView>
The DataSource of my gridview is List<CartItem>. This are the classes
public class CartItem
{
private Movie _movieInCart;
private int _Count;
public CartItem()
{ }
public CartItem(Movie movie, int count)
{
_movieInCart = movie;
_count= count;
}
public Film MovieInCart
{
get { return _movieInCart; }
set { _movieInCart = value; }
}
public int Count
{
get { return _count; }
set { _count = value; }
}
public double getSubTotal()
{
return _movieInCart.Price * _count;
}
}
public class Movie
{
private string _title;
private double _price;
public string Title
{
get { return _title; }
set { _title= value; }
}
public double Price
{
get { return _price; }
set { _price= value; }
}
//More properties here
}
Apparently the GridView shows only first level properties, but how do I show these second level properties.
Is their any way I can bind each column of the grid seperatly with each property? It is possible to do that in web form, but i am not sure about MVC grids.
View 2 RepliesI have a gridview and i'm associating the datasource for the grid view dynamically at runtime
I mean
gridView2.DataSource = titlesArrayList;
gridView2.DataBind();
And i want the data in cells of this grid view to be centered, right now they are left-justified
If i was associating data through
<asp:BoundField />
I have this property
ItemStyle-HorizontalAlign="Center"
But how can i access this property if the gridview is associated dynamically
Can I do something like this:
<asp:BoundField DataField="Field1"
HeaderText='<% IF(Eval("Field2").ToString().SubString(3,4).Equals("Text3"),"Text1","Text2") %>'
SortExpression="Field1" />
With the goal of having the header of Field1 be Text1 when the 4th-7th characters of Field2 = Text3 and Text2 otherwise?
I tried it and it just put "'<%IF(Eval("Field2").ToString().SubString(3,4).Equals("Text3"),"Text1","Text2") %>'" as the actual header string!
I have a web user control (ascx) that exposes an "ID" property. What I want to do is set this property when the SelectedIndexChanged event fires in a gridview in the containing page. However, I can't seem to do it.... Here's my code:
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
{
physicians_certif1.mdID = grdPhysicians.SelectedDataKey.ToString();
mvData.SetActiveView(viewEdit);
panAdditional.Visible = true;
}
Physicians_certif1 is the user control. It seems the user control is loading before the SelectedIndexChanged event has a chance to set it's property.
I'm currently using a GridView and I want to set the CssClass for the Row depending on a property of the object that the row is being bound to.
I tried the following but it does not work (see comments):
[code]...
Now I could simply handle the GridView's RowDataBound event and change the css class of the row there...but I'm trying to keep a clear separation between the UI and the page/business logic layers.
I am trying to bind a string that contains the ClientID of one user control to the property of another control within a GridView template column. I get the error 'lblVar02' is not declared. It may be inaccessible due to its protection level. How do I do this?
<uc:CriteriaType id="ctVar02" runat="server"
OnClientChange="<%# "toggle('" & lblVar02.ClientID & "');" %>"></uc:CriteriaType>
<uc:Label ID="lblVar02" runat="server" />
So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.
Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?
