how can i apply string.trim() accross the website when saving or editting data on the model rather then on individual fields accross the site in the controller.
View 2 RepliesIm just wondering how you go about creating dynamic properties on entities that generated from a database generated model.For example I have a UserInformation table. In that table it has basic information on the user (well derr) like user name, address details etc etc. I want to add a readonly property that concatenates the user's Name, Address details and Phone Number into one string that I can output to a view. Any ideas on how i would go about creating this dynamic property. This is just a simple example, i am wanting to do some more complex calculating and concatenating.
View 1 RepliesI need to bind a bunch of properties over my model entities. All of them uses the List<T> class. I already managed to write a model binder that can treat individualy types derived from that class, but i can't set the value of this property on the model. every time i check the model afer the bind process i see a list with 0 itens.
Here's how it runs.
After i post the values the model binder catchs up the types for bindingAt the custom model binder i check if this property is a List<T> typeIf it is then i perform the bind like it have to be, if not i let the default binder do the job.Finally i return the object binded. What happens next is the issue i've mentioned "i see a list with 0 itens" on the Model property.
Here is the code of Custom Model Binder:

I'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.
[Code]....
and the error message
Compiler Error Message:
CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.
I'm posting Json data to an action that has a model class as a parameter using the
JsonValueProviderFactory. Everything works except for any nullable properties in the model, such as double? and bool? - they always materialize as null, even if a value is posted.
I'm not sure if this issue is specific to the JsonValueProviderFactory, or MVC in general.
I'm trying to build a link to an external website using some properties of my model class in my view page, e.g. I want it to render as something like -[URL]where post-id would be pulled from the model (I'm using a strongly typed view model here - I can't use ViewData as there's a list of items being pulled back all of which need seperate links).I tried doing < a href="<% model.PermaLink(); %>">, where PermaLink is just some string, however the value doesn't get picked up.If I try < a href="<%= model.PermaLink %>">, I get an error - CS1502: The best overloaded method match for 'System.IO.TextWriter.Write(char)' has some invalid argumentsIs there any way to do this? I tried adding the runat="server" attribute, however this just linked to my local site and controller/model actions.
View 2 RepliesI have a strongly typed view. I get model passed into the view and then i assign model values to labels etc.
I would then also like to set Model values programmatically on .aspx page, like:
<%= Model.someValue = "foo"; %>
and then pass that model back to controller action and than access those values. I know that I can apply values to model like these:
<%= Html.TextBoxFor(n => n.someValue) %>
but in these case, this is not an option for me.
When it creates a view using the list scaffold the headings are hard coded. I want to pull the headings from the data model, but no luck. I was assuming LabelFor would be the solution. I must be missing something basic.
View 2 RepliesNote: I'm working with MVC3 RC and Razor views.I've got this model:
[Code]....
I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:
[Code]....
What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.
I have a view that is strongly typed and its model is of type LogOnModel. That LogOnModel has anotated properties like this one:
[Required(ErrorMessage = "Please enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Password", Description = "Your secreet password")]
public string Password { get; set; }
All of them has Display anotation with Display.Descripion property set. I want to create HtmlHelper extension method that will output <span> containg the value of Display.Description property. So for example if I called my extension method DescriptionFor than this code:
<%: Html.DescriptionFor(m => m.Password) %>
should produce following html: <span>Your secreet password</span>
Trying to share cookies accross 2 domains in asp.net, for some reason 1 domain has a '.' before the domain, and the other doesn't.
Why is that? e.g:
.staging.example.com
and
staging.example.com
Is this something to do with how I create the cookie, or a web.config change?I am not using forms authentication, just creating a cookie manually.
I am setting the cookie domain like:
HttpCookie c = new HttpCookie("blah");
c.Value = "123";
c.Expires = DateTime.Now.AddHours(12);
c.Domain = ".staging.example.com";
Response.Cookies.Add(c);
For some reason not getting the '.' in the cookie.

I have a textbox with a RegularExpressionValidator. I want to require the user to enter at least n characters. I'd also like to remove whitespace both at the start and end of the textbox. I'd still like to allow spaces within the textbox, I just want to remove the excess at the beginning and end. I basically don't know how to combine the trim regex and the count together for use in a REV.
trim: ^s*((?:[Ss]*S)?)s*$
count: .{10}.*
I basically want to know if the input, after leading and trailing whitespace is removed, is greater than n characters.
I have a new VS2010 .NET 4.0 Web project and the Properties Folder has gone wierd on me. It has lost teh "Open" under the right click. There is no way to get a Settings file created now.

How do I modify to trim all strings?
I'm trying to to display the first 50 characters of text from a database field.
I thought I could do it something like this: <%# Eval("BodyTxt").ToString().Trim("50")) %> but it doesn't work.
I've also tried this: <%# Trim(Eval("BodyTxt")) %> although I never expected that to work.
Is there an easy way to trim values in a details view during edit mode? I tried modifying the database query to trim the values, but it didn't like to do both ways databinding after that. I tried looking through all the properties of the text boxes themselves and found nothing. I know I could add an event handler for the databound event, and set all of the values one by one, but this is an application that has existed since before my employment and there are over 40 values in this details view, all in text boxes with seemingly random names that have little to do with the values they represent or obvious naming scheme.
I thought maybe there was a way to way to iterate over the DetailsView.Fields property, but couldn't figure anything out there either. I am not allowed to change the schema from CHAR to VARCHAR either. Any other quick ideas? There is a strong likelihood this page will change again, and I would like something that might take care of this problem for any new fields added in the future without extra work. Unfortunately, redesigning it is not anywhere near a top priority right now, so a quick fix to alleviate some of the headache of using this monstrosity is all I am looking for.
I have a repeater that generates last names. My issue is for the names like Smith, Jr I want to remove the comma and everything after it so that is just displays Smith. I thought the code below would work, but it doesn't.

I need help for extracting a string in a formula field.

in the string always starting part is "CFG" and ending part is "|" how can i trim the string after the first comma .
On a button click, I want to select all items in a listbox, the items will look like this for example: '14/5', then I want to extract the digits on each side of the slash for each item. The digits will be different every time and can consist of any number of digits. Do I need a loop to be sure to get all items?
