  • asp.net mvc 2 multiple partial view

    - by 303
    Hey Guys, I have a contoller that renders 3 different views. But I also have a common part (div) for every view. I thought that I can create an UserControl with own controller and include that control on my views (New controller and view as controll). How should I use that UserControl? Should it be a partial view? Or different approach - can I have multiple partial views on one page? I've been searching the web for the last view days and haven't found working solution that suits me. Also I want to use Strongly Typed views/data. Cheers

  • [VB.Net] Typecasting generic parameters.

    - by CFP
    Hello world! Using the following code: Function GetSetting(Of T)(ByVal SettingName As String, ByRef DefaultVal As T) As T Return If(Configuration.ContainsKey(SettingName), CType(Configuration(SettingName), T), DefaultVal) End Function Yields the following error: Value of type 'String' cannot be converted to 'T'. Any way I could specify that in all cases, the conversion will indeed be possible (I'm basically getting integers, booleans, doubles and strings). Thanks!

  • .NET: bool vs enum as a method parameter

    - by Julien Lebosquain
    Each time I'm writing a method that takes a boolean parameter representing an option, I find myself thinking: "should I replace this by an enum which would make reading the method calls much easier?". Consider the following with an object that takes a parameter telling whether the implementation should use its thread-safe version or not (I'm not asking here if this way of doing this is good design or not, only the use of the boolean): public void CreateSomeObject(bool makeThreadSafe); CreateSomeObject(true); When the call is next to the declaration the purpose of the parameter seems of course obvious. When it's in some third party library you barely know, it's harder to immediately see what the code does, compared to: public enum CreationOptions { None, MakeThreadSafe } public void CreateSomeObject(CreationOptions options); CreateSomeObject(CreationOptions.MakeThreadSafe); which describes the intent far better. Things get worse when there's two boolean parameters representing options. See what happened to ObjectContext.SaveChanges(bool) between Framework 3.5 and 4.0. It has been obsoleted because a second option has been introduced and the whole thing has been converted to an enum. While it seems obvious to use an enumeration when there's three elements or more, what's your opinion and experiences about using an enum instead a boolean in these specific cases?

  • ASP.NET - Google Chrome caching DropDownList selections

    - by Fake
    I'm experiencing what seems to be a caching issue with Google Chrome and Safari on my cart page. In the cart there are 2 dropdown lists. When you hit the checkout button after changing the values in the dropdown lists, it commits what's selected in the lists to the database. It's a little bit hard to explain the unexpected behavior so I will try to write it out step by step with an illustration of my problem. Lets say the first dropdown list has the values of: VALUE1 VALUE2 VALUE3 And the second dropdown list has the values of: DUMBO1 DUMBO2 DUMBO3 I add an item to my cart. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I hit Checkout. Database says: VALUE1, DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) I hit the back button. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I drop down the VALUE1 combo and select VALUE2, VALUE2 is selected momentarily and then the site posts back and VALUE1 is re-selected in the drop down list (from being reloaded from the DB) MOMENTARILY Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 THEN AFTER POSTBACK FROM DROPDOWNLIST_SELECTIONCHANGED EVENT Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 Hit Checkout. Database Says VALUE1 ,DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) Go back. Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 So it appears that it's remembering my selection of VALUE2 even though it jumped back to VALUE1 before I checked out. It seems to be a caching problem, however I've got some no-cache code to prevent caching of that page that works great in firefox and internet explorer but seems to be failing in Chrome and Safari. I'm basically returning in the headers for the cart page: no-cache, no-store, and must-revalidate to attempt to prevent caching, but based on this scenario it seems to be caching the page anyway and not reloading it when I hit the back button. I am open to any solutions or suggestions at this point. Thanks!

  • ASP.Net MVC and Windows 7 404 error

    - by Paul Rivers
    O.K. Stupid question..... I sepnt nearly a day getting an MVC site working, and then I published it. After that, the hell began. I'm using Windows 7, Visual Studio 2008 and MVC. I published it and first the Default.aspx wouldn't come up. I gave up on playing with that for a few and just did the easy thing a typed in default.aspx. I'll fix that problem later. So, I clicked on one of my navigation buttons which prior to this worked just fine in the internal development IIS, and I get a 404 error. I spent two days surfing the Microsoft support forums and every other support forum I can find. No fix. So, I tried something a little different. Just to see if I screwed up. I created a new TestMVC application. Set the output to a website on the local IIS. Compiled and after typing in the default.aspx (it was set as the startup file in the project) I then clicked on the About button on the base MVC application. And what do I get? 404. I know this is new, folks, but this is crazy. What is it about this process that would take this much effort to get it right, especially since it works on the test server.

  • Any .NET '#region directive' convention ideas ?

    - by PaN1C_Showt1Me
    I really appreciate the possibility to define regions in your code, as it improves the readability insanely. Anyways, I'd like to have everyone using the same convention in all classes (with the predefined order of all regions) like: Private Fields Constructors Class Properties Event Handlers etc... Do you have any proposition how this division could look like (What regions have sense and what names should they have) and in which order should they be defined ?

  • Asp.net mvc 3: Strange Validation

    - by coure06
    I have applied DataAnnotation based validations to two of my properties like this [Required(ErrorMessage = "Title is required")] public string Title { get; set; } [Required(ErrorMessage = "Description is required")] public string Description { get; set; } Here is the view page's code @Html.LabelFor(model => model.Obj.Title) @Html.EditorFor(model => model.Obj.Title) @Html.LabelFor(model => model.Obj.Description) @Html.TextAreaFor(model => model.Obj.Description) The Problem is that on click of submit button, on client side (js) its only giving me error for for Title and not for the Description. But Its giving me validation error for the Description after the postback. What possible causes?

  • single sign on in asp.net

    - by gopal
    Hi , We have developed implemented single sign on methodology to authenticate user. When a page is requested, if it is not authenticated then a login page will be redirected. Once they logged in the requested page will be shown. this is working when we don't assign a domain to the virtual directory. But when we assign the domain to virtual directory after the authentication the application is not redirecting to the requested page. We are using FormsAuthentication.GetRedirectUrl method to redirect the requested page. Why this is happening? How can we resolve this issue?

  • VB.NET Abstract Property

    - by ElPresidente
    I have an abstract "GridBase" class with two types of derived classes "DetailGrid" and "HeaderGrid". Respectively, one is comprised of "DetailRow" objects and the other "HeaderRow" objects. Both of those inherit from a "RowBase" abstract class. What I am trying to do is the following: Public MustInherit Class GridBase Private pRows As List(Of RowBase) Public ReadOnly Property Rows As List(Of RowBase) Get Return pRows End Get End Property End Class Public Class DetailGrid Inherits GridBase End Class In this scenario, I want DetailGrid.Rows to return a list of DetailRow. I want HeaderRow.Rows to return a list of HeaderRow. Am I on the right track with this or should the Rows property not be included in the GridBase class?

  • ASP.NET button_click not firing, after browser back button

    - by the berserker
    I have a ASPX Page that contains several user controls, which are loaded dynamically after user interaction. On one of ascx I have a hidden button that is being clicked on some user actions (via button.click()), which works fine on 1st page load. But after the form is being submitted once, the other ascx is loaded. There if user clicks the back button and resubmits the 1st form (again via button.click()), button_clicked event on server does not fire again. Any thought?

  • VB.NET encoding one character wrong

    - by Nick Spiers
    I have a byte array that I'm encoding to a string: Private Function GetKey() As String Dim ba() As Byte = {&H47, &H43, &H44, &H53, &H79, &H73, &H74, &H65, &H6D, &H73, &H89, &HA, &H1, &H32, &H31, &H36} Dim strReturn As String = Encoding.ASCII.GetString(ba) Return strReturn End Function Then I write that to a file via IO.File.AppendAllText. If I open that file in 010 Editor (to view the binary data) it displays as this: 47 43 44 53 79 73 74 65 6D 73 3F 0A 01 32 31 36 The original byte array contained 89 at position 11, and the encoded string contains 3F. If I change my encoding to Encoding.Default.GetString, it gives me: 47 43 44 53 79 73 74 65 6D 73 E2 80 B0 0A 01 32 31 36 Any help would be much appreciated!

  • Doing a lot of input validation in VB.NET

    - by Andy
    I have a form set up where users can enter their booking for a room at my college. I want to validate the user input to avoid SQL injection (my program uses a MS Access database) and also stop numbers and synbols in their name, etc. I can do the validation fine, but there is to be a lot of validation and then methods executed only if all validation tests come back as true. I did have something like this: If txtName.Text = "" Then frmBookErr.SetError(txtName, "Name field cannot be left blank.") fail = 1 Else frmBookErr.SetError(txtName, "") fail = 0 End If And then check the fail variable, but it obviously gets overridden later in the form if one of the validation tests come back as true. Can anyone provide some input into this? Thanks.

  • .Net SQL Parameter for String List Problem

    - by JK
    I am writing a C# program in which I send a query to SQL Server to be processed and a dataset returns. I am using parameters to pass information to the query before it is sent to SQL server. This works fine except in the situation below. The query looks like this: reportQuery = " Select * From tableName Where Account_Number in (@AccountNum); and Account_Date = @AccountDate "; The AccountDate parameter works find but not the AccountNum parameter. I need the final query to execute like this: Select * From tableName Where Account_Number in ('AX3456','YZYL123','ZZZ123'); and Account_Date = '1-Jan-2010' The problem is that I have these account numbers (actually text) in a C# string list. To feed it to the parameter, I have been declaring the parameter as a string. I turn the list into one string and feed it to the parameter. I think the problem is that I am feeding the paramater this: "'AX3456','YZYL123','ZZZ123'" when it wants this 'AX3456','YZYL123','ZZZ123' How do I get the string list into the query using a parameter and have it execute as shown above? This is how I am declaring and assigning the parameter. SqlParameter AccountNumsParam = new SqlParameter(); AccountNumsParam.ParameterName = "@AccountNums"; AccountNumsParam.SqlDbType = SqlDbType.NVarChar; AccountNumsParam.Value = AccountNumsString; FYI, AccountNumString == "'AX3456','YZYL123','ZZZ123'"

  • Creating a Month Dropdown in C# ASP.NET MVC

    - by Chris M
    This method seems stupid and a bit heavy; is there a more optimal way of creating the same thing (its for an MVC View Dropdown) private List<KeyValuePair<int, string>> getMonthListDD { get { var dDur = new List<KeyValuePair<int, string>>(); dDur.Add(new KeyValuePair<int, string>(1, "January")); dDur.Add(new KeyValuePair<int, string>(2, "Febuary")); dDur.Add(new KeyValuePair<int, string>(3, "March")); dDur.Add(new KeyValuePair<int, string>(4, "April")); dDur.Add(new KeyValuePair<int, string>(5, "May")); dDur.Add(new KeyValuePair<int, string>(6, "June")); dDur.Add(new KeyValuePair<int, string>(7, "July")); dDur.Add(new KeyValuePair<int, string>(8, "August")); dDur.Add(new KeyValuePair<int, string>(9, "September")); dDur.Add(new KeyValuePair<int, string>(10, "October")); dDur.Add(new KeyValuePair<int, string>(11, "November")); dDur.Add(new KeyValuePair<int, string>(12, "December")); return dDur; } }
