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.
i have some textboxes in my parent page and a search button. when the search button is clicked, my modalpopup pops up. after chosing (clicking on the select button of the row) an entry from a gridview within my modalpopup (each row in the gridview has a buttonField), the rowCommand_Event fires... within this event i try to set the .Text property of some textboxes within the page containing my modalpopupExtender... i get no exceptions, but the textboxes are not set...
ModalPopupExtender:

ModalPopupPanel:

RowCommandEvent:

I'm having problems drawing the lines on what code goes where in the following case. What goes in the View, Controller and Model. It should be noted that this is my first MVC project.So I'm building a bilingual site where the user may select either English or Norwegian language. I want the user to be able to choose language with a link at the top of the page. The link for the selected language at any time is emphasized with a certain CSS class.
The user setting with the selected language at any time is stored in a cookie at the client. When a request is done, the cookie is parsed and the settings are objectified as a part of the Model the way I've implemented it as of now (please object if you find this weird, but this is not the main focus of this post). I.e. a super-class which all my models inherit from, has the UserSettings class with the Language property.Now, where do I write the code which translates the language property into a CSS class?Option A, the View: I envision some code which interprets the language and output one of two possible lines of code based on this. We'll have IF's in the View.
Option B, the Controller: Logic in the Action method sets a ViewData-property with the name of the CSS class for both the link to the Norwegian and the English language.
Option C, the Model: I create a new property in the Model doing the same thing as the code in Option B. Except now I get strongly-typed parameters in the View and intellisense. (But I do suspect you guys will not like this solution for separation-of-concerns-reasons)
Option D, the ViewModel* I create a new class which is a ViewModel for the Model with the same property as in Option C. Now I get better separation of concerns.Yes I know there's no ViewModel in MVC, but I also know some people implement it anyway.
So what do you say? A,B,C or D? Or maybe you've got an E?
I am not sure why this is not working.
<asp:Label ID="lblTitle1" runat="server" Text='<%= string.Format("{0} <br /> {1}","Part 1", "Part 2") %>' ></asp:Label>
I just want to combine two resource string as text of label?
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.
I'm trying to change a Label's text property and colour properties depending if an event occurs on the page behind file.
Does anyone have a similar issue?
if (((Label)FindControl("Label1")).Text != null) - //getting Object reference not set to an instance of an object.
{
Label Labelmerchantid = (Label)FindControl("Label1");
Labelmerchantid.Visible = true;
Labelmerchantid.ForeColor = System.Drawing.Color.Red;
}
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?
Is it possible to use InvokeMember() of Type class to call a property of a property of a class?

I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:

I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.
<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox>
<a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">
However, I keep getting this error:
Property access must assign to the property or use its value.
How would I be able to accomplish this?
how can I use a Required Validation in a property Prop2 only if the Prop1 is true?
public bool Prop1 { get; set; }
[Required] // I need this validation only if the Prop1 is true.
public string Prop2 { get; set; }
I wondered what the difference between
'dbo.Property' and 'Property'
would be in an sql query
I would like to dynamically load a user control and assign one of its public properties OnLoad...
I'm doing the following from a parent user control to dynamically load the child user control...
UserControl uc = (UserControl)Page.LoadControl("~/Controls/MyUserControl.ascx");
What else do I need to do to pass a value so its public property is set OnLoad?
When I open an ASP.NET 3.5 project using VWD2010, I get a prompt error message,"The connection property in the web.config file is missing or incorrect.The connection string from the .dbml file has been used in its place."however, my project works successfully.

I have a type that is derived from an Entity generated by the Entity Framework 3. How do I assign one Customer's Order property to the Derived Customer's Order property?
derivedCustomer.Orders = customer.Orders
I'm not actually trying to swap orders; this is just an example of what I am trying to achieve. Has anyone done tried this and succeed?

The OriginalSource property of the object identifies the original object that received/initiated the event. Consider a custom control (called CustomControl1 in this example) that is composed of a TextBlock. When a MouseDown event is raised on the TextBlock, the OriginalSource property will be the TextBlock, but in CustomControl1's handler, the Source will be changed to the CustomControl1 object so that other elements along the event's route will know that CustomControl1 received a MouseDown.
Is there equivalent of WPF OriginalSource event property in Winform and ASP.NET ? If not how to emulate this ?
I created a control where other developers can create an instance and use. There is a button click in the control. How do I allow developers to plug in their own code in a certain part of my control? I am not sure if or how exactly to use a delegate or event in this scenario.

In an MVC view, I'm looking for a way to determine if a parent entity's collection of child entities is empty, so I can decide if I need to call a RenderPartial() or not.
For a one-to-one I've been using the following:
<% if (Model.Book.GenreReference.EntityKey != null) %>
{.....}
but I'm unsure how to do it in a one-to-many scenario, or if it can even be done without the use of Include() or Load().
Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.
