How To Pass Reference Types To Methods
May 24, 2010I have this very simple test program that illustrates my question. I am not sure why this returns a null for the 'customer' variable. I would have thought that since the method MyTestMethod created a new Customer object that the value of 'customer' wouldnot be a null.

MVC :: How To Pass Values To Action Methods Without Parameters
Jan 20, 2010Is there any possibility to pass values of form elements to action methods but using parameters?I have a form with a lot of input fields and the method signature will get pretty long. Besides the form elements depend on each other so if the user makes a special choice only a subset of the form elements should be displayed so there are several combinationof values to be passed.Can I access the posted values in a generic way through a collection in the controller or something similar?

C# - How To Organize Code (methods I Create For Various Uses On My Website)
Oct 14, 2010I wrote some code to connect the application to it's database, then I created some code to use the connection code and retrieve, update or add some values to the database, Also I might have some code to deal with other stuff than to deal with the database
The code is a little complicated, maybe it's simple but it's not short, for example to write a good piece of code to just retrieve a single value so I could set the controller with this value I used this :
SqlConnection sqlconnection= new SqlConnection(ConfigurationManager.ConnectionStrings["DefConnectionString"].ConnectionString);
SqlCommand sqlcommand = new SqlCommand("SELECT name FROM message WHERE id = 3", sqlconnection);
try
{
sqlconnection.Open();
lbl_name.Text = (string)sqlcommand.ExecuteScalar();
Status.Text = "Done";
}
catch (Exception ex)
{
Status.Text = ex.Message;
}
finally
{
sqlconnection.Close();
}
I might even add some code to store some info in the database about any exception is thrown, I think the code is pretty basic, yet it's not small, given that it's the smallest piece I'll need, some huge code is written for adding or editing new items, and also consider that it's not the only code I'll write in the page, the page has more needs.
I've provided a detailed case I hope!...So what do you think will be the best way to make my page fast and easy to read and have an organized code I've started placing every code in an appropriate method, but some methods are common so I create them again in every page that needs them like a ConnectionToDataBase Method, and mean while I think I just organized the page so I could mainly look at Page_Load and see what are the called methods and then scroll down to read the definition but It's still a big page and note the best practice I think
Sorry for all the big question, I just provide details so I could get a reasonable answer for my question, I hope everyone benefits from it as most questions are pretty basic, newbies like me needs some detailed cases and answers to get a better start.
EDIT: I know I'm new, So any comments on my code are more than welcome!

Create Different Search Methods Using Radio Buttons
Apr 12, 2013I am trying to create different search methods using radio buttons. This is a web app. using asp.net and vb.net
1)Radio Button 1 - search by Account Number - txtAccountNumber
2)Radio Button 2 - search by Customer Last and First Name - txtLastName, txtFirstName
3) Radio Button 3 - search by Customer ZipCode - txtZipcode
One search button - btnSearch
By default, the search button is aligned to the txtAccountNumber (next to txtAccountNumber)
If option 2 is selected, the search has to align to txtLastName, and other txtboxes are visibly disabled
If option 3 is selected, the search has to align to txtZipcode. and txtboxes are visibly disabled
I tried the followings, but it did not work.
Protected Sub rbSearchZipcode_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs) Handles rbSearchZipcode.CheckedChanged
txtAccountNumber.visible = false
txtLastName.visible = false
txtFirstName.visible = false
btnSearch.visible= true
txtZipcode.top = btnSearch.top
This worked for windows form, but not for web form.

Jun 22, 2010I want to be able to create methods to do stuff like opening the connection to the database.Right now if I want to do that I have to put all the code to open the connection with the database in every class.What I did is create a new class called methods, this class is in the App_code folder.I have researched but don't understand how methods are created and how to call them.

Web Forms :: Export String Arrays To Excel?
Oct 25, 2010Anyone know how to (have the code) to export a couple of string arrays to excel when clicking on a button?
for example, I have arrays:
string [] test = new string[500];
string [] test2 = new string [500];
i need to export in a linear vertical fashion such that column A1 - A500 contains test. Then B1-B500 contains test2.
Something easy like this.

Using Extension Methods In Static Methods On Extended Classes?
Aug 16, 2010I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()

Forms Data Controls :: Use Multiple Arrays And Bind Them To One Repeater
Feb 21, 2010Apparently I am trying to do something that is a little unorthadox here. I am trying to use multiple arrays and bind them to one repeater in C#. I would think that there has to be a reasonably easy way to do this but I can not seem to find it anywhere online. This is what I have so far (that works). How do I bind multiple arrays to this one repeater though?
// Bind Array to Repeater repTest.DataSource = arrTest1; repTest.DataBind();
<form id="formTest" method="post" runat="server">
<asp:Repeater ID="repTest" runat="server"> <HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%">
</HeaderTemplate> <ItemTemplate> <tr height="30px">
<td width="40%"> <%# Container.DataItem %> </td> </tr>
</ItemTemplate> <FooterTemplate> </table> </FooterTemplate>
</asp:Repeater> </form>
