I currently have an ASP .NET MVC / EF4 project that contains many pieces of autonomous functionality such as a blogging, events, contests, wiki, etc.
The entities used by each system are all mapped to my database through one giant EDM file.
This works well for the main site, but I also have a few personal sites where I want to reuse just the blogging functionality from the mains ite.
My biggest problem is that due to the mac daddy EDM file, my blog sites have to constantly have their database schemas updated to reflect changes made to areas of functionality that they don't use (i.e. changes to the events system).
The only other gotcha is that there are some entities (Users and Tags) that have relationships with entities from each area of functionality, making it hard to simply split each area of functionality off into its own EDM.
With all of this said, I'm trying to figure out the most efficient way to set this up.
Should I go down the road of splitting up the EDMs by each area (blogs, events, contests, wiki) and figuring out a way to maintain relationships for the User and Tag entities?
Or should I just perhaps be creating an EDM for each website that only maps the entities that it will actually need? The only problem with this is that my repository layer takes in a UnitOfWork/ObjectContext, and by creating new ObjectContexts for each site I'd have problems reusing my repository code.
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?
I just moved to a new PC and installed VS 2010. I copied all of my websites over from the old machine and now when I open the old websites on the new machine, they do not show up in my recent projects list on the start page. New websites that I make do show up there but the old ones do not. This is very inconvenient. Is there a way to make old projects that I open show up in the list?
This brings up another question. Is there a way to make a shortcut that will open VS2010 up with a website already loaded so that I don't have to go through the file open dialog every time?
I've seen some teams that start breaking into multiple projects from the beginning and others build behemoth single projects. The large project teams say that one massive project is easier to maintain than multiple smaller projects.
View 4 RepliesI need to create a sample project (for educational purposes) and I'm faced with the choice between Web Site Projects or Web Application Projects. This feels similar to the choice between C# and VB. My question isn't about the differences between these 2 choices, but rather which is more popular (relevant, recognizable) to the general ASP.NET community.Has anyone seen any statistics in terms of adoption/usage of these 2 different project types? What project type should I use to reach the widest audience?Update: I created a poll on this subject - http://poll.fm/2e6cy
View 4 RepliesI have a multi-tiered application. I would like to publish the class libraries to UI developers to let them add to their web or windows projects to add all the functionality.
I would like to restrict access so only a certain project can be referenced. The reason is so that they do not refer to the data access layer directly and start making calls that would bypass the business logic built into the business tier.
UI->>Business Logic->>Data Access
So in other words, BL and DA are deployed as compiled assemblies. BL references DA. UI will reference BL, but I would like to strictly prevent any other project from referencing DA directly.
Is there a way to share user controls between various projects ?
I have created user controls like login control, menu control, header control, lost password control and etc and they are all connected to sql database for data.
I would like to share these between various web site projects, it means I have same functionality and the only modifications I can do is within CSS styles.
Do I need to copy modules or is there a way to keep them as shared classes/modules and call what I need every time I need it?

i am trying to bind data to a datagridview control on an ASPX webpage and am using something like this..
<asp:TemplateField HeaderText="MyField">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "MyField") %>
</ItemTemplate>
</asp:TemplateField>
the problem i am having is that the data for the 'MyField' field is actually an integer that is a reference to a string value in another sql table.
Does anyone know how i can reformat my code line above to show the string value instead of the int value?
I will start a new project in a couple of weeks and I have some questions about ASP .NET WebForms. Visual Studio ofters some nice wizards such as the SqlDataSource component that you can assign to a GridView and then you can edit and delete rows without coding.
The disadvantage of these wizards is the bad seperation between the layers and thereby the maintance of the software. One good example is the SQL statement in the view (*.aspx files) and so on. I would like to ask you how you handle this in your projects. Do you use the wizards? Otherwise if the wizard would not be used then it is a lot of effort necessary to program all features of the GridView component self. Such as edit, sort, paging etc. Is there information available how you can do this? I didn't find really something. What is your opinion about this.
I am having datagridview control with dynamically added BoundField columns.I want to have tetxboxes in each cell of the gridview so taht user will enter data in gridview textboxes and at last on button click it will be saved in database.
View 14 RepliesI have a piece of code that is just HTML. It was previously created as a user control. Within the application i'm working with there are two seperate websites that are interlinked to make one website. There is a documents section where users do not need to login and a data section where users need to login. The design was implemented long before I was hired. My problem is I want to use the code from the documents website with the data website but I can't seem to register the control. I only one this piece of code in one place so when it is updated it doesn't have to be in multiple places. I tried setting "src=http://website/doc/doc.ascx" but this errors out saying
<%@ Register Src="http://website/doc/doc.ascx" TagName="docs" TagPrefix="temp" %>
Parser Error Message: The file '/documents/http://website/doc/doc.ascx' does not exist.
It adds the directory as part of the src. How can I have it point to this location http://website/doc/doc.ascx ?
I have spent most of my time writing ASP.Net web pages, using VS 2005. I am now developing some client function for Windows, so I'm relatively less expert in VB.In my Windows program I have defined a DataGridView and linked this to a data table (within a tableadaptor). Now I want to populate it: on a web page's code-behind I would write Gridview.databind(). What is the equivalent with a DataGridView.
View 1 RepliesIn my application, every time the active tabpage changes, I connect to a database, fill a datatable, and bind it to my data control. That's all the functionality.
The main reason I don't want to use the ajax tabcontrol is because of the way it's rendered on the browser. Assuming that
tabcontrol.autopostback is true, the user clicks on another tabpage and he will see the tab change, and for a fraction of a second he'll
see the data previously displayed in that tab. Then the page will do postback and the data in that tabpage will be refreshed. It just seems awkward. I also want it to work even if javascript is disabled.
I also tried using the multiview control, but it doesn't work without javascript.I simply want a "tabcontrol" similar to the one used on ebay.com. Once you do a search, you'll see three tabs: "All items", "Auctions only", and "Buy It Now Only". I can have everything disabled (active scripting, Flash, etc) and they still work.
can one web user control gives two different functionality on two different web pages,suppose i use web user control on web form 1 and also web form 2 , but i want some more work from this control on web form1 but this more work not affect on web form 2. for example: button click event of web user control gives me Good Morning message on screen, when i use this control on web form 1 and web form 2 ,it will give me Good morning message on screen,when i click this button, But i want that ,this control give me Good Morning message and some other messages like good after noon on web form 1 only, one control but different functionalty on two different pages

Here's the Design View: I'd like to add code in the code behind to perform additional edits. I added the "ErrorMessage" LiteralControl. How do I access it from the code behind or is there a preffered way to display a custom message using the control's functionality?
Currently my code resembles this:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomPanel.ascx.cs"
CodeFile="CustomPanel.ascx.cs" CodeFileBaseClass="System.Web.UI.WebControls.Panel"
Inherits="MyProject.CustomPanel" %>
...
namespace MyProject
{ public partial class CustomPanel : System.Web.UI.WebControls.Panel
{ ... }
}
However, I'm really not sure how to proceed from here, because this does not appear to follow a logical inheritance path that includes System.Web.UI.UserControl / Am I doing something wrong? How can I inherit Panel and extend standard event-handlers, such as PreInit?
I am trying to add some client side functionality to a user control that I have written.
A really simplified version of my scenario is as follows:
I have a control called MyControl. This has a javascript method called doSomething that simply shows the current date and time in an alert box.I add an instance of MyControl to a page called WebForm1. I want to be able to call myControl1.doSomething when a regular (non ASP.NET) button on WebForm1 is pressed.
I'm sure this is really simple but I can't for the life of me figure out what I need to do make doSomething available.
I ran an ASP.NET page that i have under development on my local IIS. It uses some dragPanelExtenders as well as some other AJAX Control Toolkit AJAX client side stuff, and in order to show the page to somebody, I wanted to put it up as a plain HTML file, hosted on a live web server (running APACHE). (This is the only public web server I have access to, and I want them to be able to drag some panels and experience the page as it would be when "live")
So, I viewed the page running on my local IIS, then saved the source as a HTML file.
Then copied this HTML file to the web server ( as well as necessary CSS, JS and image files).
When I view this HTML file through the web server, I get this error :
ASP.NET Ajax client-side framework failed to load.
By debugging, I see that the following lines were in my saved HTML :
<script src="/Insata10/WebResource.axd?d=VAXZudqFsChpNfB" type="text/javascript">
<script src="/Insata10/ScriptResource.axd?d=Dwbyv-OIp-kJQdqf_UMh7wUzi2" type="text/javascript">
<script type="text/javascript">
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
So, at runtime, the referenced resources "ScriptResource.axd" and "WebResource.axd" were not found.
Is there any way to get whatever is needed from those AXD's to my HTML file, without actually executing anything on IIS?
Could you point me to a reference article on how to implement drag and drop within a treeview control using ASP.NET in C#? Is this best implemented with AJAX? I will be using an XMLDatasource. Also, I did not want to use any third party control at this point
