I have a case that I need to set the Text property for an asp label in the aspx page not from code behind. More exactly, I need to set a value to asp control in aspx page and this value is set by a property in the same page code behind.
I need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:
I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:
[Code]....
I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like [Code]....
This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?
I would like to do this: Dim str As String = class.isGuest("yes") but it won't work.
Public Property IsGuest(ByVal guestStatus As String) As String Get Dim guestCookie As New HttpCookie("g") For Each key As String In Context.Response.Cookies.Keys If key = MYACCOUNT_SESSION_COOKIE_NAME Then guestCookie = Context.Response.Cookies.Item(MYACCOUNT_SESSION_COOKIE_NAME) Exit For End If Next guestCookie.Value = guestStatus Response.Cookies.Add(guestCookie) Return guestCookie.Value.ToString End Get Set(ByVal value As String) Dim guestCookie As New HttpCookie("g") guestCookie.Value = value Response.Cookies.Add(guestCookie) End Set End Property
I have a txt file, in which read only property is true. When I try to write some text in that file through the vb coding, it's through the error. I have shown the code below.
Dim fs As FileStream = File.OpenWrite(HttpContext.Current.Server.MapPath("Include/CacheKeyFile.txt")) Dim sw As New StreamWriter(fs) sw.Write("Menu setup updated by " & value & " on " & DateTime.Now.ToString()) sw.Close() fs.Close()
I found the cause of the error. If we set the Write access property to false, we can open the file and write it without showing the error messages.
I need to remove the Read only property for a file through the vb. Net code. Is it possible? Can we set the read only for txt file before open and write operation?
s there any code to generate property automatically from datatable?I mean there is a table A with column id,name,address.Run the code and this will generate a class automatically to set and get property.Property of that class will be the column name of the datable A.
why can't it see this property or the server method RedirectToPayPal? I get a runtime error of :
'ASP.cart_aspx' does not contain a definition for 'RedirectToPayPal' and no extension method 'RedirectToPayPal' accepting a first argument of type 'ASP.cart_aspx' could be found
I am trying to use a property from the code-behind to populate a textbox instead of using in the code-behind textbox.text=. I am using vb.net. Here is the code for the aspx page:
Is it possible to access a code behind property for a server tag? I have a property on my code behind page that i want to pass into a javascript function i.e.
I want to code some colors in the style property of some controls. For instance, I want to use some like DarkGoldenrod, which is shown as
ARGB=(255, 184, 134, 11)
How do I convert this to something that I can use in a style property (e.g., style="color: #CCCCCC)? I know how to convert the first three numbers (255, 184, 134) into a six digit hex value, but what do I do with the fourth number (11)?
I'm having problems drawing the lines on what code goes where in the following case. What goes in the View, Controller and Model. It should be noted that this is my first MVC project.So I'm building a bilingual site where the user may select either English or Norwegian language. I want the user to be able to choose language with a link at the top of the page. The link for the selected language at any time is emphasized with a certain CSS class.
The user setting with the selected language at any time is stored in a cookie at the client. When a request is done, the cookie is parsed and the settings are objectified as a part of the Model the way I've implemented it as of now (please object if you find this weird, but this is not the main focus of this post). I.e. a super-class which all my models inherit from, has the UserSettings class with the Language property.Now, where do I write the code which translates the language property into a CSS class?Option A, the View: I envision some code which interprets the language and output one of two possible lines of code based on this. We'll have IF's in the View.
Option B, the Controller: Logic in the Action method sets a ViewData-property with the name of the CSS class for both the link to the Norwegian and the English language.
Option C, the Model: I create a new property in the Model doing the same thing as the code in Option B. Except now I get strongly-typed parameters in the View and intellisense. (But I do suspect you guys will not like this solution for separation-of-concerns-reasons)
Option D, the ViewModel* I create a new class which is a ViewModel for the Model with the same property as in Option C. Now I get better separation of concerns.Yes I know there's no ViewModel in MVC, but I also know some people implement it anyway.
So what do you say? A,B,C or D? Or maybe you've got an E?
I have a control and list of variables and I want in the control property to be assigned to the variable value directly in the page not from the back code, something like this
My global variables
public string Banana = "banana_pie"; public string Apple = "apple_pie";
in my custom control instead of:
<uc:LoadPie id="pieBanana" type="banana_pie" />
To this
<uc:LoadPie id="pieBanana" type="<%=Banana %>" />
so is there a way or just assign the property in page back code.
I created a simple gridview user control with a custom property ProfileType which should load different records depending on the ProfileType value when attaching to a web page.
This is my web page:
[code]....
how I can expose user control custom property at its code-behind file.
Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.
Is there any difference between accessing a property that has a backing field
private int _id; public int Id { get { return _id; } set { _id = value; } }
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?
