It is a hyper-legible collection of 223 icons with a tiny footprint—ready to use with Bootstrap and Foundation. [View the collection](http://useiconic.com/open#icons) 5 | 6 | 7 | 8 | ## What's in Open Iconic? 9 | 10 | * 223 icons designed to be legible down to 8 pixels 11 | * Super-light SVG files - 61.8 for the entire set 12 | * SVG sprite—the modern replacement for icon fonts 13 | * Webfont (EOT, OTF, SVG, TTF, WOFF), PNG and WebP formats 14 | * Webfont stylesheets (including versions for Bootstrap and Foundation) in CSS, LESS, SCSS and Stylus formats 15 | * PNG and WebP raster images in 8px, 16px, 24px, 32px, 48px and 64px. 16 | 17 | 18 | ## Getting Started 19 | 20 | #### For code samples and everything else you need to get started with Open Iconic, check out our [Icons](http://useiconic.com/open#icons) and [Reference](http://useiconic.com/open#reference) sections. 21 | 22 | ### General Usage 23 | 24 | #### Using Open Iconic's SVGs 25 | 26 | We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute). 27 | 28 | ``` 29 | icon name 30 | ``` 31 | 32 | #### Using Open Iconic's SVG Sprite 33 | 34 | Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack. 35 | 36 | Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `` *tag and a unique class name for each different icon in the* `` *tag.* 37 | 38 | ``` 39 | 40 | 41 | 42 | ``` 43 | 44 | Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `` tag with equal width and height dimensions. 45 | 46 | ``` 47 | .icon { 48 | width: 16px; 49 | height: 16px; 50 | } 51 | ``` 52 | 53 | Coloring icons is even easier.

38 | 39 | @functions { 40 | public Person Person { get; set; } = new Person { FirstName = "John", LastName = "Doe", Age = 32 }; 41 | } 42 | ``` 43 | 44 | As you can see I'm using two components: `ValidationError` and `ValidationSummary`. The first one is used to display specific problems with a `Subject`'s `Property`, and the second one gives you an overview of all validation errors on the `Subject`. 45 | 46 | ## Validating entities with .NET 47 | 48 | .NET has a couple of built-in mechanisms for validation, and I support the two most important: `IDataErrorInfo` and `INotifyDataErrorInfo`. 49 | 50 | `System.ComponentModel.IDataErrorInfo` has been around since .NET 1.0, and allows you to return an error for each property, and for the whole object: 51 | 52 | > `System.ComponentModel` contains classes and interfaces which are available throughout most of .NET, including `INotifyPropertyChanged` and is in my opinion one of the most important namespaces! 53 | 54 | ``` csharp 55 | // Summary: 56 | // Provides the functionality to offer custom error information that a user interface 57 | // can bind to. 58 | [DefaultMember("Item")] 59 | public interface IDataErrorInfo 60 | { 61 | // 62 | // Summary: 63 | // Gets the error message for the property with the given name. 64 | // 65 | // Parameters: 66 | // columnName: 67 | // The name of the property whose error message to get. 68 | // 69 | // Returns: 70 | // The error message for the property. The default is an empty string (""). 71 | string this[string columnName] { get; } 72 | 73 | // 74 | // Summary: 75 | // Gets an error message indicating what is wrong with this object. 76 | // 77 | // Returns: 78 | // An error message indicating what is wrong with this object. The default is an 79 | // empty string (""). 80 | string Error { get; } 81 | } 82 | ``` 83 | 84 | The biggest drawback of `IDataErrorInfo` is that you can only return one error per property, but on the other hand this interface is supported by WinForms, WPF, ASP.NET Mvc, etc... 85 | 86 | `INotifyDataErrorInfo` is a more modern version of `IDataErrorInfo`: 87 | 88 | ``` csharp 89 | // Summary: 90 | // Defines members that data entity classes can implement to provide custom synchronous 91 | // and asynchronous validation support. 92 | public interface INotifyDataErrorInfo 93 | { 94 | // 95 | // Summary: 96 | // Gets a value that indicates whether the entity has validation errors. 97 | // 98 | // Returns: 99 | // true if the entity currently has validation errors; otherwise, false. 100 | bool HasErrors { get; } 101 | 102 | // 103 | // Summary: 104 | // Occurs when the validation errors have changed for a property or for the entire 105 | // entity. 106 | event EventHandler ErrorsChanged; 107 | 108 | // 109 | // Summary: 110 | // Gets the validation errors for a specified property or for the entire entity. 111 | // 112 | // Parameters: 113 | // propertyName: 114 | // The name of the property to retrieve validation errors for; or null or System.String.Empty, 115 | // to retrieve entity-level errors. 116 | // 117 | // Returns: 118 | // The validation errors for the property or entity. 119 | IEnumerable GetErrors(string propertyName); 120 | } 121 | ``` 122 | 123 | This interface allows multiple errors per property. 124 | 125 | Here is my implementation of a simple `Person` class supporting both interfaces: 126 | 127 | ``` csharp 128 | public class Person : IDataErrorInfo, INotifyDataErrorInfo 129 | { 130 | public string FirstName { get; set; } 131 | 132 | public string LastName { get; set; } 133 | 134 | public string FullName => $"{FirstName} {LastName}"; 135 | 136 | public int Age { get; set; } 137 | 138 | const int minAge = 18; 139 | 140 | public string this[string property] 141 | { 142 | get 143 | { 144 | return GetErrors(property).FirstOrDefault(); 145 | } 146 | } 147 | 148 | public string Error 149 | { 150 | get 151 | { 152 | return null; 153 | } 154 | } 155 | 156 | public bool HasErrors => GetErrors(null).Any(); 157 | 158 | public event EventHandler ErrorsChanged; 159 | 160 | public IEnumerable GetErrors(string property) 161 | { 162 | if (property == null || property == nameof(this.FirstName)) 163 | { 164 | if (string.IsNullOrEmpty(this.FirstName)) 165 | { 166 | yield return $"{nameof(FirstName)} is mandatory"; 167 | } 168 | if( this.FirstName.Length < 2 ) 169 | { 170 | yield return $"{nameof(FirstName)} '{this.FirstName}' is too short."; 171 | } 172 | if( this.FirstName == "Q") 173 | { 174 | yield return $"{nameof(FirstName)} 'Q' is reserved for extra-dimensional beings!"; 175 | } 176 | } 177 | if (property == null || property == nameof(this.LastName)) 178 | { 179 | if (string.IsNullOrEmpty(this.LastName)) 180 | { 181 | yield return $"{nameof(LastName)} is mandatory"; 182 | } 183 | if (this.LastName == "Doe") 184 | { 185 | yield return $"{nameof(LastName)} cannot be 'Doe'"; 186 | } 187 | } 188 | if (property == null || property == nameof(this.Age)) 189 | { 190 | if (Age < minAge) 191 | { 192 | yield return $"{nameof(Age)} should be at least {minAge}"; 193 | } 194 | } 195 | } 196 | } 197 | ``` 198 | 199 | ## Onto ValidationError 200 | 201 | Let's look at the `ValidationError` Blazor component: 202 | 203 | ``` csharp 204 | @using System.ComponentModel 205 | @using Microsoft.AspNetCore.Blazor.Components 206 | 207 | @if (Errors.Any()) 208 | { 209 |

217 | } 218 | 219 | @functions { 220 | 221 | [Parameter] 222 | protected object Subject { get; set; } 223 | 224 | [Parameter] 225 | protected string Property { get; set; } 226 | 227 | public IEnumerable Errors 228 | { 229 | get 230 | { 231 | switch (Subject) 232 | { 233 | case null: 234 | yield return $"{nameof(Subject)} has not been set!"; 235 | yield break; 236 | case INotifyDataErrorInfo ine: 237 | if( Property == null ) 238 | { 239 | yield return $"{nameof(Property)} has not been set!"; 240 | yield break; 241 | } 242 | foreach (var err in ine.GetErrors(Property)) 243 | { 244 | yield return (string)err; 245 | } 246 | break; 247 | case IDataErrorInfo ide: 248 | if( Property == null ) 249 | { 250 | yield return $"{nameof(Property)} has not been set!"; 251 | yield break; 252 | } 253 | string error = ide[Property]; 254 | if (error != null) 255 | { 256 | yield return error; 257 | } 258 | else 259 | { 260 | yield break; 261 | } 262 | break; 263 | } 264 | } 265 | } 266 | } 267 | ``` 268 | 269 | As you can see, it is pretty simple. First I check if there are any error, and then I use a `div` with nested `ul` and one `li` per error. 270 | 271 | The `div` has a class `validationerror` associated with it so you can style it: 272 | 273 | ``` css 274 | .validationerror > ul > li { 275 | color:red; 276 | } 277 | ``` 278 | 279 | The `Errors` property returns an `IEnumerable` of errors, which checks the `Subject` for one of the interfaces using the new C# 7 pattern matching syntax: 280 | 281 | ``` csharp 282 | switch (Subject) 283 | { 284 | case null: 285 | yield return $"{nameof(Subject)} has not been set!"; 286 | yield break; 287 | case INotifyDataErrorInfo ine: 288 | ... 289 | case IDataErrorInfo ide: 290 | ... 291 | } 292 | ``` 293 | 294 | You can learn more about C# 7 pattern mathing (here)[https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-7#pattern-matching]: 295 | 296 | If `Subject` has not been set I return a validation error to the developer! Otherwise I read the validation errors through the interface and return them using C#'s `yield` syntax. 297 | 298 | Again, if `yield` is not familiar, read [this](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/yield). 299 | 300 | ## ValidationSummary 301 | 302 | The `ValidationSummary` components works in very much the same way: 303 | 304 | ``` cshtml 305 | @using System.ComponentModel 306 | @using Microsoft.AspNetCore.Blazor.Components 307 | @using System.Reflection 308 | 309 | @if (Errors.Any()) 310 | { 311 |

(propertyNames = GetSubjectPropertyNames().ToList()); 370 | 371 | private IEnumerable GetSubjectPropertyNames() 372 | { 373 | return Subject.GetType() 374 | .GetProperties(BindingFlags.Public | BindingFlags.Instance) 375 | .Select(pi => pi.Name); 376 | } 377 | } 378 | ``` 379 | 380 | The big difference here is that I need to show all property's errors, and for this I use a little reflection: 381 | 382 | ``` csharp 383 | private List propertyNames = null; 384 | 385 | private List PropertyNames 386 | => propertyNames ?? (propertyNames = GetSubjectPropertyNames().ToList()); 387 | 388 | private IEnumerable GetSubjectPropertyNames() 389 | { 390 | return Subject.GetType() 391 | .GetProperties(BindingFlags.Public | BindingFlags.Instance) 392 | .Select(pi => pi.Name); 393 | } 394 | ``` 395 | 396 | Because **reflection is slow** I cache all properties so I only have to get them once. 397 | 398 | ## Summary 399 | 400 | That's it! Because Blazor allows me to use the same constructs as normal .net, I can use familiar interfaces and techniques. 401 | 402 | The full project is available on (my GitHub)[https://github.com/PeterHimschoot/Blazor.Validation]. 403 | 404 | 405 | 406 | 407 | -------------------------------------------------------------------------------- /Screenshots/BlazorValidation.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/PeterHimschoot/Blazor.Validation/1263bb1202784483e2730219e58922725715eaec/Screenshots/BlazorValidation.PNG -------------------------------------------------------------------------------- /global.json: -------------------------------------------------------------------------------- 1 | { 2 | "sdk": { 3 | "version": "2.1.300-preview2-008533" 4 | } 5 | } 6 | --------------------------------------------------------------------------------
