I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".
[Code]....
And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.
Does anybody know why? How can I display the category correctly only with set?

I created a simple Master Page in Visual Studio 2008:
<%@
Master
Language="VB"
CodeFile="MasterPage.master.vb"
Inherits="MasterPage" %>
<!DOCTYPE
html
PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
and got green underlined 'Master' with two warning messages: 1.Validation (ASP.NET): This attribute name must be followed byan equal (=) sign and a value. If the value is in quotation marks, the quotation marks must match. 2. Validation (ASP.NET): Attribute 'Master' is not a valid attribute of element 'Control'.How I can get rid of the messages?

I am trying to create a minimum length validation attribute which will force users to enter the specified minimum amount of characters into a textbox
public sealed class MinimumLengthAttribute : ValidationAttribute
{
public int MinLength { get; set; }
public MinimumLengthAttribute(int minLength)
{
MinLength = minLength;
}
public override bool IsValid(object value)
{
if (value == null)
{
return true;
}
string valueAsString = value as string;
return (valueAsString != null && valueAsString.Length >= MinLength);
}
}
In the constructor of the MinimumLengthAttribute I would like to set the error message as follows:
ErrorMessage = "{0} must be atleast {1} characters long"
How can I get the property's display name so that I can populate the {0} placeholder?

So, I've got an contact form in my MVC 2 application.
I'd like to programatically email all properties of my "ContactModel".
Here is what I'd like to do in psuedo-ish code:
[Code]....
In case it matters...ContactModel sets up the DisplayName attributes like this:
[DisplayName("First Name")]
public string FirstName {get; set ;}
I'd like to keep this nice and DRY by not repeating the DisplayName names.
Specifically, I'd like to enumerate over each property in my ContactModel, get its DisplayName, and get its submitted value.

I think I might have stumbled onto a bug in ASP.NET MVC 3 RC. When I setup my MVC2 project in a new MVC3 project, copy paste classes, code, change name spaces, etc, etc, I ran into an issue in the following, simplified for explanation purpose, scenario:
Model:
public class WineDetails
{
[SkipRequestValidation]
[Required(ErrorMessage = "Beschrijving verplicht")]
public string Description { get; set; }
}
ViewModel:
public class ViewModelCreateWine
{
public MasterData MasterData { get; set; }
public WineDetails WineDetails { get; set; }
}
ActionMethod:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateWine(ViewModelCreateWine viewModelCreateWine)
{
GetMasterDataRegions(viewModelCreateWine);
if (Request.Params.ToString().IndexOf("Save") > 0)
{
if (TryValidateModel(viewModelCreateWine.WineDetails))
{
m_wineService.CreateWine(viewModelCreateWine.WineDetails);
return RedirectToAction("index", "Admin");
}
}
return View(viewModelCreateWine);
}
The ActionMethod "CreateWine" needs to call the "CreateWine" method in the WineService so that in the end a new Wine is added to the Database. So far it looks ok. As shown in the above code the [SkipRequestValidation] is set on the "Description" property of the WineDetails model so that the user can add Rich Text to the description and HTML elements are allowed during the Request validation. This works perfectly fine until the Params collection of the Request is accessed in the code to check if the Save button is clicked. When this line of code is trying to execute the following exception is thrown:
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ViewModelCreateWine.WineDetails.Description="<p>HTML Content with...").
The same exception is thrown when I put the [ValidateInput(false)] attribute on the action method. When I comment out the "if" statement and its content there is no issue and the model validation works just fine and skips the Request Validation on the Description property as expected.
In MVC2 the above code worked fine with the [ValidateInput(false)] attribute on the action method.As I said I'm not sure if this is a bug, it very well might be my own stupidity, but I thought it would be worth to mention here. So any feedback is more than welcome.

I'm building a custom web control with a public property which I only want to be available in design time (i.e. make it unavailable in code behind). The DesignOnly attribute promises to do just that, but when I set [DesignOnly(true)] it has no noticeable effect whatsoever:
[Bindable(true)]
[Category("Appearance")]
[DefaultValue(null)]
[Localizable(false)]
[DesignOnly(true)]
public string MyProp
{
get
{
return ViewState["MyProp"] as string;
}
set
{
ViewState["MyProp"] = value;
}
}
The property still appears in code behind IntelliSense. Setting a value to it in code behind works. In these respects, the behavior is just as if the attribute had never been set. And I've cleaned and rebuilt the complete solution. Twice.

my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.

I'm basically trying to get a div containing a loading gif to show on my page at runtime. I call it from a button click event as well as in the code flow. It was working before I used the AJAX Update Panels. I've since taken them out as they were causing issues with RegisterClientScriptBlock. By the way, does commenting out the AJAX Markup like this...

I have got a composite control and i would like to dictate which attribute/property is assigned to the control first from the markup?example in the aspx file:
<MM:MyControl ID="" runat="server" ViewType="normal" BaseType="RealBase"></MM:MyControl>
when the control gets created from the mark-up above, ViewType will be assigned first, Which is what I do not want, I would like RealBase to be assigned first under all circumstances. This control is to be users by other developers so I cannot just switch the order.

I have a multi view which contains a view which contains a panel. the name of this panel is "Panel1"I have the following code and my HTML does not display in the rendered page. Any idea why this isn't working, i must be doing something wrong? sw = simple html statement, any would produce same result.
String mstring = sw.ToString();
Panel1.Controls.Add(new LiteralControl(mstring));
i am using dotnetnuke also, not sure if that is where the issue is.

I have a web form with an Asp.net PlaceHolder control. By default the control is set to visible false and will be displayed through the code behind based on several criteria. In general this PlaceHolder control wraps several other Asp.net controls. Now a new requirement ask that the controls within the PlaceHolder control be visible at all times an no longer hidden. So in the Aspx code I changed the laceHolder attribute and set it to visible. Now all kinds of Java Script validation errors are occuring and it is a horrible spahgetti code nightmare. Is their a way to set the visible attribute on the control and not have it trigger the validation?

I am having a problem setting the SystemObjectRecordID attribute of my custom control inside a repeater. Currently, the value winds up as zero in the database. Things I have checked:
1) The datatype of the DB column (bigint) and the datatype of AlertId (long) and the datatype of the getter/setter SystemObjectRecordID variable (long) match.
2) If I set '<%# ((Alert)Container.DataItem).AlertId %>' to the Text attribute of a label I get the expected results. So, it has something to do with my custom control and specifically how data isbound to the SystemObjectRecordID attribute.
Now, going to the server, below is what I have for databinding (The page is Default.aspx.cs and the namespace is Company.ProjectWeb.Profiles):

Currently I am trying to pass the value received from a literal (because I know that the values are received as expected here) to the SystemObjectRecordId object. Still isn't working. I am still getting a value of zero when I set a breakpoint and look at the value of SystemObjectRecordId in the codebehind of my control:
