Web Forms :: How To Make The Separate Code File Work
Oct 21, 2010
I am using some code I found that generates a random password. I am in the habit of putting code in a seperate file. The code was written in the same file and I'm trying to move it to a seperate file and get the following message. Also, below, I posted
the original code (code on same page as aspx) and what I did (code in seperate file).what adjustment needs to be made to make the seperate code file work?
Compiler Error Message: BC31143: Method 'Public Function GeneratePassword(length As Integer, numberOfNonAlphanumericCharacters As Integer) As String' does not have a ignature compatible with delegate 'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'.
Source Error:

I've done a search and read a few things, All i'm trying to do is set a variable in the code file and call it in the page file asp.net vb.net 3.5. I've tried like this in the code file:
[Code]....
And in the design part of the page:
[Code]....
But it says that name isn't declaired. What am I doing wrong?

I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?
Included (Showing page events just under the tab):

The project I'm working on allows an end-user to modify CSS code to integrate the application as best possible. Most of the CSS values are stored in a database and need to be retrieved and parsed dynamically. I setup a Style controller, and gave each stylesheet an action, and then passed the configuration data through to the View. I set the ContentType to "text/css" and then generated the stylesheets. This works fine, but the problem I'm running into is this: none of the code works in the application. I include it in the head code, but it doesn't parse in the code. An example of what I do is this:
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" ContentType="text/css" %>
.element {
background-color: <%= ViewData.Model.BackgroundColor %>;
}
I include it like so:
<link href="/style/Basic" rel="stylesheet" type="text/css" media="all" />
When I include the CSS code in a partial view and include it using the ViewModel (wrapped in style tags) in an action, then everything works fine. It is when I try to parse this as a separate file when it does not work. Is there something I am doing incorrectly? Or is there some kind of glitch?

I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...
How can I make the class recognize that the interface exists but is in a different file?
Here's some code:

I recently started NOT putting code in separate file. I am using vb. I am having a problem with my database connection.

This question has probably been answered before, when adding a new web form, I do not see an option that allows you to place code in a seperate file for a project (it does it automatically). But for websites, I see the option. Am I missing some option?

In my orginal post i asked the question to handle this within the .Net side.
I was trying to stay away from using SSIS package, and with help from another member, i was able to get the process to work with an excel spreadsheet.
But part of my project requires us to allow .csv files.. so my question is how can i modify the code i have now for the excel to work with a .csv file?
You can find the current code in my original post here:
[URL]
I not sure what the best solution is for the end result.. I was reading somewhere online that you can right the data from the file to a datalist or gridview so you can present the user with a view of what is being uploaded, then use that datacontrol to insert into SQL.
In my current code, im uploading the file, then using that file to do the insert. This works fine for .xls files.. but i need to accomplish the same thing for a .csv file.

I did the following:
(1) File / New / Web Site
(2) Right-clicked on new website name
(3) Selected "Add New Item..."
(4) Selected Web Form
(5) Didn't see any check boxes for selecting either "Place code in separate file", or "Select master page".
The checkboxes are missing. Is this a configuration problem?

I'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:
- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).
- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).
The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:
< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>
Code behind send to database:
protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}
}.............................

I am trying to make 2 separate AJAX calls using buttons. What I want to happen is: when Button1 is clicked ProductsTable shows data from the webservice; when Button2 is clicked OthersTable shows its own data from the webservice. But right now, when either button is clicked, nothing shows up. I know the code works if there's only one of them and it's not wrapped around a .click function.
No error messages. ASP.NET 4.0, JQuery 1.4.4. Not using ScriptManager. Not using UpdatePanels.
Code below:

I'm working on a webforms aspx app (not MVC) and I'm not sure if I should just create separate pages or somehow make multiple views on the same aspx page for the following scenario: Basically, I need to give the user the option to view a set of data a few different ways (essentially different group by's from a data perspective)... the data is always the same, its just a matter of how to arrange on the page...
each way I need to present the data will essentially consist of 2 repeaters, one nested inside the other. The outer repeater will display a nice header section with the nested repeater showing the list of items under that heading. view by book title (title is outer repeater, with the book list being the nested repeater, yes, multiple books with same title for this example - the app has nothing to do with books, this is just to illustrate)
Book Title: A Good Story

Or, view books by publisher (here the publisher would be the outer repeater and the list, with different fields compared to first view, is the nested repeater.

so what do I do here? Just making separate pages is simple and would work, but is there something else I should be considering? There will be 3 different views, so 3 pages total if I went that route. Something is making me think I should be doing this all within one aspx page? maybe just toggling the visible property of the repeater controls? but then I was thinking each of these repeater controls is databound, and I assume even if they are not visible they still incurred database hits to get the data, right? and that could be bad?

I would like to make a custom accordion, in which I have 2 panes, but where you couldn't open the second one until you clicked a validation button in the first one that would open the second...
I tried to just make a button that would hide the first pane but I cant get to make it work.

I am not sure exactly which topic this post should go under...
Here is what I am doing.
I have a web form where a person will edit their blog article. At some point, once they are done editing, they can click a button "Publish Blog Now".
Once the blog is published in the click event on the server side I am doing a query to get a list of subscriber email address.
These are people who subscribed to this blogger and wish to receive an email notification whenever this person publishes a new blog.
What I just realized today is that my hosting provider only allows me to send a maximum of 200 emails per hour. Which means in my loop I need to sleep for roughly 20 seconds between each email notification sent. But I dont want the user who clicked the publish button to have to sit there and wait while that process is going.
How can I return to the user but yet continue to run some code on the server side to send out the emails in the background even if user closes web browser?
This is an ASP.NET web application targeting .net 4.0 and I am using c# as my back-end language and VS2010 as my development tool.

While it has gnerally been advocated to separate code from mark up and all that, with the razor syntax and webmatrix all that is not valid anymore, I think. WebMatrix encourages code and mark up in the same page! So what is the best practice as far as code and mark up is concerned.
