Generic Parameter - Pass Another Control Type And Execute Exact Same Logic
Nov 30, 2010
I have a class constructor which accepts a Listbox.
[Code]....
I need to be able to pass another control type and execute the exact same logic in one of the methods... Seems like a use for Generics... I'm not so sure about the syntax... The type of control that I will pass is a rad combo box which has many of the same properties of the listBox control. However, RadComboBox does not inherit from listBox or dropDown so I am unable to cast. When changing the signature of the constructor to As RadComboBox as well as the property and field the method works as expected. I am trying to avoid duplicating code here.

In Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists
Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note:
you do have 3 files if your making WebApplication but if your making website you only get 2 files?
UserControl.ascx
UserControl.ascx.cs
so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.

I have several custom classes that derive from a common base class so they share several members in common. I would like to be able to pass objecs from any of these three classes to a function that will "look at" common properties. However, it seems there is a catch 22 -- When I try to access a member (.FirstName) of the passed object, the computer reports an error that it thinks the member doesn't exist.
It seems to be a sort of contradiction -- since I didn't declare the type, the computer can't confirm existence, but it seems that it should have to take it on faith since the generic character of the type is specified by the code. Possibly there is something I don't know about that would fix this. I'm showing VB code for what I have so far. I went ahead and hardcoded an instance to confirm that the object exists and has the needed property. I commented out the line that had the code that resulted in the computer reporting an error.

I'm trying to create a control out of a class I found, and one of the overridden functions is the following:
protected override void PerformDataBinding(IEnumerable data)
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.

I'm trying to create a validation layer that will contain methods to validate all my objects (in my Business Objects layer) .. but when I try to reference both the validation and business objects to each other I get a circular dependency error .. so I've decided to create a new layer (BLL) to validate the objects for me and I'll be able to reference both the validation and the object layers.
so I want to build some kind of class/interface -I don't know what fits more- to be like a generic type or a parent type that my method could accept it as a parameter and check for it's Name/ID property. Instead of defining a new method overload for each object type I have

if there is anyway that I could duplicate controls in a asp.net pages. So for example, currently for one of my pages, I have a panel at the top of the page with alot of controls in them ( eg next/previous buttons, labels, trees, etc). However I wanted to add the exact duplicate of this panel on the bottom of the page aswell, with exact functionality.

I have a server control that performs some logic. I'd love to provide a default implementation of this logic in the code of the control, but allow a developer to pass an alternate implementation of this logic in as a delegate, if they wish.
So...
<prefix:MyControl FooLogicMethod="MyUtilityClass.MyFooLogicMethod" runat="server"/>
If they don't specify this, I'll use my default method. If they do specify it, I'll use the method they passed in.
Can I do this as a delegate, or do I need to reflect it?

I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.

In one of the methods I'm using in my MVC app, there's a param that accepts a list collection of strings. If I have a string parameter, I can give it a default value of an empty string, but I cannot seem to give the list collection a default value of a new, empty list collection. I get the error that's beginning to seriously grate on my nerves about requiring a compile-time constant. getting the generic list to work with a default empty set?

I have a method like:
public T Get<T>(string key)
{
}
Now say I want to return "hello" if the type is a string, and 110011 if it is type int.
how can I do that?
typeof(T) doesn't seem to work.
I ideally want to do a switch statement, and return something based on the Type of the generic (string/int/long/etc).

Is there a schedule control in asp.net.
What I need:
column display: users
Rows display : months and days.
On clicking cell will open a popup
In popup we can :
- select a status in a dropdownList,
- if the status is "be close" => two calendars ( date start and end)
- then apply a color for the selected period.
I know I would not find an exact need control, but I want a component that would be closest.

I've had a bit of a problem trying to bind a generic list to a repeater. The type used in the generic list is actually a struct.
I've built a basic example below:
[code]....
I then create two fruits using the struct (apple and orange). These fruits are then added to the list.
Finally, I bind the generic list to the DataSource property of the repeater...
The markup looks like this:
[code]....
I expect to see the fruit name and price printed on the screen, separated by a horizontal rule.
At the moment I am getting an error relating to actual binding...
**Exception Details: System.Web.HttpException: DataBinding: '_Default+Fruit' does not contain a property with the name 'FruitName'.**

I'm busy writing a handler to serve various documents for download or presentation in web forms pages. The documents range from various image formats, to PDF, to MS Office documents, to generic binaries. My basic draft of the download process is as below:
[code]....
However, I have some misgivings about lumping all documents together as application/octet-stream, and I would prefer, if feasible, to use a more specific content type per document type. I have a DB table for document types where I could store this. Am I going in the right direction, and if so, where can I find a suitable starting list of content types for document types?
