generated dynamic form

Installation

The package can be installed via NPM : npm install --save devextreme-dynamic-form

Devextrem project

If you are already using devextreme in your angular project, you don't need to add anything, just install it and enjoy it

Devextreme don't configured yet

if you are not using devextreme in your angular project, you have to add those two dependencies : npm install --save devextreme devextreme-angular

then, in your angular.json (angular-cli.json), add the dx.common.cssand the theme you want to use, for example :

{ 
  ... 
  "apps": [ 
    { 
      ... 
      "styles": [ 
        ...
        "../node_modules/devextreme/dist/css/dx.common.css", 
        "../node_modules/devextreme/dist/css/dx.light.css", 
        "styles.css" 
      ], 
      ... 
      } 
    } 
  ], 
... 
} 

You will need to also to add this in your tsconfig.json

"compilerOptions": {
    ...
    "paths": {
        "jszip": [
            "node_modules/jszip/dist/jszip.min.js"
        ]
    }
}

Configuration

. In order to use this component, you need first to import DxDynamicFormrmModule in your app.module, or the module that will be holding this component :

@NgModule({ 
  ...
  imports: [ 
  ...
    DxDynamicFormrmModule 
  ], 
  ...
}) 
export class AppModule { } 

. Create a class, for example Test and decorate all your attributes with annotations (decorators):

import {FormDeco,FormTypes,SectionForm} from "devextreme-dynamic-form";

export class Test {

    @SectionForm("Secion1")
    section;

    @FormDeco({
        label : "text Area",
        type : FormTypes.TEXTAREA,
        defaultValue : ""
    })
    firstField;

    @FormDeco({
        label : "select multiple choice",
        type : FormTypes.SELECT,
        datas : [{value : 0, text : "devextreme"},{value : 1, text : "devextreme-angular"},{value : 2, text : "devextreme-dynamic-form"}],
        required : true,
        multiple : true,
        defaultValue : [0,1]
    })
    secondField;

    @FormDeco({
        label : "select an email",
        type : FormTypes.INPUT,
        required : true,
        isEmail : true,
        isEmailErrorString : "please enter a valid email!",
        lengthString : true,
        max :10,
        lengthErrorString : "email too long !!"
    })
    theirdFild;

    @SectionForm("Seciont2")
    section1;

    @FormDeco({
        label : "Radio groupe",
        type : FormTypes.RADIO,
        datas : [{value : 0, text : "devextreme"},{value : 1, text : "devextreme-angular"},{value : 2, text : "devextreme-dynamic-form"}],
        defaultValue : 2
    })
    fourthField;

    @FormDeco({
        label : "Date selector",
        type : FormTypes.DATE,
        defaultValue: new Date(),
        required : true
    })
    fifthField;

    @FormDeco({
        label : "Number selector",
        type : FormTypes.CHEKBOX,
        min : 3, // if not given, no min is considered
        step : 0.1 //default 1
    })
    sixthField;
}

And create a ts file where you export all classes from witch you want to generate a form, lets call it handler.ts, in our case, it will contain only this line:

export {Test} from "./test";

handler.ts will be used to instantiate the forms'classes.

. In your app.component.ts, import DxDynamicFormComponent and handler.ts content :

import * as handler from "./handler";
import { DxDynamicFormComponent } from 'devextreme-dynamic-form';
...
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  @ViewChild(DxDynamicFormComponent) dxDynamicForm : DxDynamicFormComponent;

  handlerInst = handler;
  ...

}

handlerInstwill be passed as an @Input() param to dx-dynamic-form

. In your app.component.html, just add the selector tag of the library with some input parameters :

<dx-dynamic-form 
    [handlerInstantition]="handlerInst" 
    colNumber="2" 
    width="1200" 
    nameCls="Test">
</dx-dynamic-form >

. Finally, if you wana retreive selected or introduced datas of the form, you have to call generateDataToSend method line this :

this.dxDynamicForm..generateDataToSend();

this method will first check if the form is valid, if it's not, it return an empty array, and display alerts in fields in which there a validation error.
