I have a class with many properties - strings, booleans, etc. This class was created from Entity Framework.
Now I want to quickly create the controls for the properties. I dont care about linking the controls to an object - I can do this later. I just find it a pain to create 50+ controls on the webpage when the class could be used to create a 'template'.
I think I've created and instantiated my first custom class. I'm pretty darn excited! Been reading up on it, I think I did it right but I'd like someone to double check. I'm trying to collect question ID's and associated answer values from a databound gridview and then insert them into the database.
I have two questions:
-Did I set up and instantiate the new class correctly? (also will need to access the class on other webpages)
-Am I ready for the next step of inserting into the Database with LINQ or is there something else I need to do?

My 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?
We have a SQL agent job tied to an SSIS package that process does an Update process on the dimensions and a full process on the Facts. In the morning the cube is showing that it is processed but the new data is not present. When it is manually run the SSIS package, it seems to work fine. Basically there is job having two steps, one is to update the BI Cube and next step is to update dimensions and facts. This jobs runs perfectly without any error, but first step executes as per the expectation and second fails to update with latest data. If we try to manually run the SSIS Package of the second step it perfectly updates with the latest data.

View 3 RepliesHere's an interesting problem. I have an ETL script written in c# that I have been running manually on a somewhat regular basis. It is used to update my web app's database.
I want to automate the ETL process AND create an interface for the web app admins to manually start the ETL process.
I could have sql server kick off the ETL process on a schedule and implement a button or something on a web page that will do the same thing, but I don't want to put my code in 2 different places because I don't want to update it in 2 places when it changes. But I don't know how to make my web app tell SQL server to manually start a scheduled process. Can this be done? OR
I could somehow implement the scheduling in the web app itself, but by now most people are familiar with the problems that are faced when trying that (app may not be running at certain times, must wait on request to start a process (without some trickery)). Also, since the ETL process takes a while, I don't want to make some poor end user wait on a response, so it would definitely have to use a new thread.

View 1 RepliesI have been tasked with producing a web application for a new client. What they're looking for requires a Gridview with slave Detailsview within an Update Panel.
I produced this, including the Gridview in markup, as follows:[Code]....
[Code]....
However, although it works, it's been requested that I move most of this to code behind (for easier maintenance), which is causing me a few headaches.
What is the correct option here, since I see many potential methods?
Should I create an instance of the Gridview and Update Panel in markup, then define all events and columns in code behind? Create a new Gridview entirely in code behind and place it within the Update Panel? Create both in code behind?
I have gridview control where i have added two templates one template is the dropdown box another one is the text box.
I have common controls (Edit,update,cancel)
In the form i have one button .
On click on the button one new row is created in the grid view
Now how do i fetch the data entered in the dropdown box and the textbox.
How to reload the updated data to the dropdownbox,textbox.
On edit(twice) click it is switching to Update and cancel mode
On Cancel(twice) click it is switching to Edit mode.
I have created a gridview at runtime. its working fine when i load the grid first time. after when i am selecting next value from ddl to load grid according to that option(selecting from dropdown list and coresponding values showing in grid) showing error that "A field or property with the name 'datafield name' was not found on the selected data source."
might be i am getting this error becuze the privious value is not being cleared"

View 2 RepliesI'm working on a site that will offer a free service. It's a very simple site: A visitor will choose some text files from their PC, and once he has finished choosing them, he will click on the "Submit" button. This "Submit" button will simply upload the text files to X folder on the server and run a 3rd-party executable that will process these files. That's it. The exe will be doing all the work and creating a new file that the user will be downloading. This is the problem: I've found out the hard way that shared hosting plans don't allow executables on their servers. So it's been suggested that I purchase a VPS or dedicated server plan for this, but the cheapest one I found is $39/mo.
Although my site will have a "premium" service, it's mostly free, and I wasn't expecting to spend too much on hosting. As a matter of fact, I was planning on using my current shared plan for this. My question is: is there any other way of being able to do this? It would need to be automated; being free, tons of people (hopefully) will go to the site, start uploading text files, and wait for the result. I could do it manually (download the text files from the server, run the EXE locally, and finally upload the result and email the user), but that's almost impossible.
I´m trying to automate a confirmation email going out to a newly registered user.
I've added reference to the interop.outlook library and I import it to the asp webpage. It actually works, so that´s fine.However I don´t really know what´s going on here, so maybe you guys can tell me?
1. What needs to be installed on the server for this to work?
2. Who will be the sender? When I do this locally, I´m the sender, but on the site??
3. Will it work?

View 1 RepliesI have what's bound to be a stupid question, so I'll apologize for what I think should be an obvious answer my brain just can't see. My problem is very simple. I have a Repeater control bound to a SqlDataSource. The ItemTemplate in this case is one complicated beast, and rendering can take a loong time if too many records are returned; so I need to maintain tight control over how many records are brought back from the data source.
Is there not some way of either stopping the creation of subsequent RepeaterItems once a certain count has been reached, or cancelling the bind if more than a certain number of records are returned? I know I can grab the record count from the AffectedRows property in the Selected event of the DataSource, but I've encountered a brain-lock on how to stop/inhibit the binding (or RepeaterItem creation beyond x records).
I'm happy with either aborting the binding altogether if the record count is too high (displaying no records), or simply stopping it after X records are returned; at this point, I'm not picky. Either way would work, and it seems I ought to be able to readily figure out either one, but my brain has simply gone into neutral.
I had successfully created a functionality where I can dynamically add rows and columns to a asp table by creating/re-creating controls on every page load.
I have 2 buttons - Add rows and Add columns that, basically according to a asp.,net page life cycle, occur in the following order and work perfectly fine.
Page load is fired and controls along with their viewstate are recreated. In Add row button click event - I just create a new table row and add controls to each cell dynamically.
Same thing with Add column, Delete Row and Delete Column button click events.
However, now I added a Dropdown which when its index is changed needs to retrieve values from the database and create controls based on those values and then also bind the Db values.
But it doesn't work correctly since the asp.net page cycle cannot capture the dropdown's selected value in page_load as the page_load fired first and then the selectedindexchanged event is fired later, the controls are not created.
I don't know how to handle this scenario and incorporate it into my existing code.
I'm trying to build a website for real estate listing. now the data would look like a datagrid. and while clicking on it, it should open under the clicked row the dynamic data related to the specific row. (like an AJAX accordion). this website for example ( ignore the language, couldnt find any better example [URL] Now, i've been told that this works by using "Dynamic Div Creation" which i have no idea how it should work this way. Is it possible to make it work by using an Accordion inside a datagrid? or what?

What are some good automated tools for load testing (stress testing) web applications, that do not use record and replay of HTTP network packets?I am aware that there are numerous load testing tools on the market that record and replay HTTP network packets. But these are unsuitable for my purpose, because of this:he HTTP packet format changes very often in our application (e.g. whenwe optimize an AJAX call). We do not want to adapt all test scripts just becausethere is a slight change in HTTP packet format
