Jinget.Blazor 6.2.19-preview021

Jinget Blazor

Blazor components optimised for RTL languaged such as Farsi, Arabic etc.

Components list:

• Captcha
• Date Picker
• Date Range Picker
• Message Box
• Modal
• List
• Table
• Dynamic Form
• JingetDropDownList
• JingetDropDownListTree
• Input

Services list:

• LocalStorage
• SessionStorage

How to Use:

Download the package from NuGet using Package Manager: Install-Package Jinget.Blazor You can also use other methods supported by NuGet. Check Here for more information.

Add Services:

Register the required services in your Program.cs file:

builder.Services.AddJingetBlazor();

If you need to use TokenAuthenticationStateProvider as a provider for handling authentication state(for example in your ASP.NET Core Blazor project), then you need to pass addAuthenticationStateProvider=true to AddJingetBlazor. If you need to use token storage services for storing/retrieving your tokens, then you need to pass tokenConfigModel and addTokenRelatedServices=true to AddJingetBlazor. If you do not need to use token storage services, but you want to register TokenConfigModel then you need to pass tokenConfigModel and addTokenRelatedServices=false to AddJingetBlazor. If you have no plan to use Jinget.Blazor components and you just want to use its services, then you can pass addComponents=false to AddJingetBlazor method.

How to Use Methods:

Login and Logout user:

If you want to authenticate the user and manage user's state via TokenAuthenticationStateProvider then you can inject UserService to your login form and authenticate the user:

@attribute [AllowAnonymous]
@layout LoginLayout
@page "/login"
@inject NavigationManager NavigationManagerService;
@inject UserService userService;
@inherits BaseComponent
@{
    base.BuildRenderTree(__builder);
}
<input type="text" id="username" @bind-value="@UserName" />
<input type="password" id="password" @bind-value="@Password" />
<button @onclick="Authenticate">ورود</button>

@code {

    string? UserName { get; set; }
    string? Password { get; set; }

    async Task Authenticate()
    {
        var result = await userService.LoginAsync(UserName, Password);

        if (result)
        {
                NavigationManagerService.NavigateTo("/", true);
        }
        else
        {
            await ShowErrorAsync("Username or password is incorrect");
        }
    }
}

await userService.LoginAsync method will call the LoginAsync defined in IAuthenticationService interface. You can implement IAuthenticationService interface and write your own logic to authenticate the user. Similiarly in order to logout the user you can call await userService.LogoutAsync().

        }

    }
}

Parameters:

Model: Model used to decorate the form. two-way binding is also supported.

Rtl: If set to true, the the form will be rendred Right-to-Left. Default is true.

CustomStyle: Custom css style used for the whole form.

Properties:

DynamicFields: Returns a list of fields rendered on page.

Properties: return the list of elements used to rednder the dynamic form

Methods:

FindElement: Find element by id.

FindElement<TFormElementType>: Find element by type.

Callbacks:

OnModelChanged: This event raised whenever a member's value changed.

OnFieldReady: This event raised whenever a field rendered on page. This event gives an object of JingetDynamicField which contains a property called RefObject which refers to the form element on page. For example in order to get the drop down list items in OnFieldReady using ((JingetDropDownList)field.RefObject).Items.

Attributes:

JingetTextBoxElement: Render a textbox on the page.

JingetTextAreaElement: Render a textarea on the page. Using Rows property you can set the textarea rows.

JingetEmailBoxElement: Render an email input on the page.

JingetNumberBoxElement: Render a number input on the page.

JingetPasswordBoxElement: Render a password input on the page.

JingetTelephoneBoxElement: Render a tel input on the page.

JingetColorBoxElement: Render a color input on the page.

JingetDateBoxElement: Render a date input on the page.

JingetDateTimeLocalBoxElement: Render a datetime-local input on the page.

JingetHiddenBoxElement: Render a hidden input on the page.

JingetMonthBoxElement: Render a month input on the page.

JingetTimeBoxElement: Render a time input on the page.

JingetUrlBoxElement: Render a url input on the page.

JingetWeekBoxElement: Render a week input on the page.

JingetDatePickerElement: Render a JingetDatePicker on the page. You can set Culture and EnglishNumber properties.

JingetDateRangePickerElement: Render a JingetDateRangePicker on the page. You can set Culture and EnglishNumber properties.

JingetDropDownListElement: Render a select input on the page. If IsSearchable=true, then the user can do search among drop down list items. Using PreBindingFunction user can define a method to run before BindingFunction. This method's signature is:

public async Task<string> PreBinding(string? token) => await Task.FromResult("This is pre binding");

Using BindingFunction user can define a method to bind data into drop down list. If GetTokenBeforeBinding is set to true, then before running the BindingFunction, ITokenStorageService.GetTokenAsync() method will be called to read the token from localstorage where localstorage key is equal to TokenConfigModel.TokenName. (See builder.Services.AddJingetBlazor();). This method's signature is:

public async Task<return type> <Binding function name>(string token, object? preBindingResult)=>...

BindingFunction can be either async or not.

Using PostBindingFunction user can define a method to run after BindingFunction. This method's signature is:

public async Task<string> PostBinding(string? token, object? preBindingResult, object? data) => await Task.FromResult("This is post binding");

Jinget DropDownList components

Add the JingetDropDownList to your page and start using it;-)

<JingetDropDownList @ref=@ddlSample
                    Id="ddlSample"
                    DataProviderFunc=@GetData
                    DefaultText="---Choose---"
                    HelperText="This is sample drop down list"
                    DisplayName="DDLSample"
                    IsDisabled=false
                    IsReadOnly=false
                    OnChange=@OnChange></JingetDropDownList>

Parameters:

Id: Unique identifier for component in page. This parameter is required.

Value: Value entered in the input box

DisplayName: If string has value the label text will be displayed in the input, and scaled down at the top if the input has value.

HelperText: The HelperText will be displayed below the text field.

IsSearchable: If true, then user can search among the dropdownlist items.

DefaultText: Sets a default text to be shown in dropdownlist before selecting anything

DataProviderFunc: Defines a method which is used to populate the data in dropdownlist.

ParentElementId: Defines where to attach the dropdown html in page. By default element will be attached to body tag in page. But in some cases like Bootstrap modals, which tend to steal focus from other elements outside of the modal. Since by default, Select2 attaches the dropdown menu to the body element, it is considered "outside of the modal". To avoid this problem, you may attach the dropdown to the modal itself by setting the modal id in this parameter.

Callbacks:

OnChange: Fires a callback whenever the selected item changed.

OnDataBound: Fires whenever the Items changed.

OnRendered: whenever the component rendered on the page.

Services

LocalStorage/SessionStorage:

If you need to work with localStorage then you need to inject ILocalStorageService and if you want to work with sessionStorage then you need to inject ISessionStorageService to your page or classes. Both of these methods have same methods with same signatures. Note that these two services are registered in DI container if only you set the tokenConfigModel to non-null value and also set the addTokenRelatedServices=true while adding builder.Services.AddJingetBlazor(); to Program.cs.

Methods:

GetItemAsync: Get item with specific key from storage.

GetAllAsync: Get all items from storage.
