I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.
I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?
I am working on Crystal Reports 8.5 and SQL Server 2000 as backend. I have a stored procedure which has been added to the Crystal Report. So that fields are visible in the Fields object section from where i can drag and drop the fields on the report and display it. But now as they want more fields i have written two select statements for displaying required fields. But these newly added fields are not visible in the Fields object section in the Crystal Reports. I have done verify database, removed and again attached the SP but the problem is not solved.

Does the current MvcRouteHandler support something similar to Monorail's concept of an controller area? a way to group the controllers.
View 1 Repliesi'm in a project with a service layer (WCF), a proxy layer that are between this service layer and the "controllers". Every controller should call this proxy layer to get data, and instead return a model to be rendered, returns a bigger entity that i've to convert using Linq to a more little model. Then pass it to the view.
Do you think is a good idea that this conversion be done by the controller? In my opinion the controller is not the responsable to shape the incoming object from the proxy layer. This object should be returned by the proxy layer and the controller should pass it to the view directly.
I wounder if there are samples how to create Restful serivece withmvc. Or I can use MY controllers to get data and post data?
View 2 RepliesI want to test that when my form data is posted back to my controllers that the data annotations and the model binding is going to do its job and give the correct model state. After googling for a while I can't find a really good tutorial or article that shows how to do this.
Can anyone point me in the right direction? What is the best practice in this area? I have read that I may need to use moq and MVCContrib but I have not read a tutorial that makes me shout, "Yes, this is the right way to do it!"
I'm starting a new ASP.NET MVC project, and I decided to put my controllers in a different assembly. Evertyhing works fine, but I have hit a problem: I created a new area in my MVC Project, called Administration. I have an AdminController Class in my seperate assembly which is supposed to return views from my Admin area, but everytime it tries to return a view, it looks for it in the wrong place (~/Admin/SomeView.cshtml Instead of ~/Administration/Admin/SomeView.cshtml) How can I tell the controller to look for views in the wanted area?
View 1 RepliesI am wanting to create a path somewhat like this: /Administration/News and have it forward to a News controller instead of it being the action.How would I go about this?
View 3 RepliesI was wondering what the major differences are between controllers and webservices. I understand webservices can receive postbacks via ajax while controllers cannot. Also, when you put a webservice in a MVC site, what file structure do you use to store it? Just create a single services folder?
View 4 RepliesBasically what the title says. I created a new MVC application. I'm trying to add new pages to the site, but anytime I do I get the following error:Server Error in '/' Application.The resource cannot be found.Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
namespace MyAppMVC.Controllers
{
public class ProductsController : Controlle{
public ActionResult Index()

I'm currently migrating a WebForms app over to MVC. One problem I have is that some users will probably have a page like www.mysite.com/login.aspx bookmarked (or maybe some other .aspx page). Currently this will throw an InvalidOperationException stating that the controller 'login.aspx' could not be found. Is there any way I can handle this so that it redirects the user to another page?
I know I can implement Application_Error in the Global.asax file, but I'd rather not redirect on any InvalidOperationException, just when it's an invalid controller.
I would like to have a project that contains all of my Controller logic. I'm not concerned with using Areas, as these are still maintained within the same project. Consider this scenario: I have multiple sites/apps that require the exact same interaction in regards to a particular area, say CRUD ops on a user account. I do not want to create all of the controller logic for one site/app, recreate it again for the next, and make sure that I keep all maintenance to each in sync. I would prefer to keep the controllers in a separate project and reference them from the appropriate site.
I know someone will say that the controller logic is a lot of times specific to the application (as I've read elsewhere), but let's just say that it is guaranteed to be the same. I want to focus on the "how" and not the "why". So far, I've created a class library project with the appropriate references for accessing System.Web.Mvc. How do I proceed with the routing configuration for this? Is this idea even possible? I read a few older articles that were written when Areas were first being introduced that said to create separate projects for them. Is this idea similar to that?
I am developing a restful web api using asp.net mvc and trying to extend the MVCWEBAPI project on codeplex that i took from here - http://code.msdn.microsoft.com/MvcWebAPII have added a folder nested within API folder inside the Controllers folder.This path does not work - (nested folder Security)http://localhost/API/Security/Authentication/LoginAlthoug, this path works - (not nested)http://localhost/API/Media/GetMediaThe folder structure is Controllers ->APIWithin API folder I added a Security folder and then added AuthenticationController under it.To make the routing work, I updated global.asax.csBelow is the required code.

I mean parameters of methods of controllers. For example, I have a View, which has :1. One radiobutton Yes / No (table inside DB has bit field)2. dropdownlist with int values (table has int too)3. Textbox (Firstname for example)I can create a method:

Does it make sense to do error handling and logging inside actions methods or handle the OnException method inside the controllers. One way means writing try/catches in all the action methods even when there is nothing to be done to recover from the error. Handling this at the controller level would allow logging and redirection to an error handler page without writing try/catches inside all the action methods.
Which method makes the most sense? Here is example code of try/catches in an action method.

public ActionResult Delete(int id)

For applications that need to have fastly different view layers, and I would like to still use the idea of the controller. I would ideally like to but the controllers in a Class Lib. and then have only the Views in a MVC Web Application. Taking the model out in this way works well, but I can't find a nice way to split the views and controllers.

View 1 RepliesI'm using the release 1 candidate from a few weeks ago and am loading my controllers from the spring.net context. I notice that my factory which couldn't be simpler keeps being called for a controller called "css". I'm using the Razor template engine. Does mvc or razor create any behind the scenes controllers that I don't know about?
View 2 RepliesI have an ASP.NET 4 MVC2 multi-language application and I need the same HomeController to response ДОМОЙ as well.Our application has 12 Controllers and should support 9 different languages.The optimal solution would be to override some FindControllerByName & FindViewByName, but I can't find such functions.
Do any of you guys know how can I achieve such a behavior?
