Text Field

The TextField component allows you to type text in your app. The TextField has attributes such as secure for handling password fields, and pipes for specifying the text format the control should use.

Usage

Styling

<TextField hint="Enter text" color="orangered" backgroundColor="lightyellow" />

Creating TextView component via Code-Behind

<StackLayout id="stackLayoutId">
    <Button text="{{ secureButton }}" tap="{{ onTap }}" />
            <Label text="{{ 'Result: ' + tfResult}}" textWrap="true" />

</StackLayout>

function onPageLoaded(args) {
    const page = args.object;
    const vm = new observableModule.Observable();
    const stackLayout = page.getViewById("stackLayoutId");

    vm.set("username", "john");
    vm.set("tfResult", "");
    vm.set("secureButton", "TextField secure:(OFF)");
    vm.set("secure", false);
    // changing TextField secure property value on button tap
    vm.set("onTap", (btargs) => {
        const secure = vm.get("secure");
        vm.set("secure", !secure);
        if (secure) {
            vm.set("secureButton", "TextField secure:(OFF)");
        } else {
            vm.set("secureButton", "TextField secure:(ON)");
        }
    });
    // creating new TextField and binding the text property
    const options = {
        sourceProperty: "username",
        targetProperty: "text"
    };
    const firstTextField = new textFieldModule.TextField();
    firstTextField.updateTextTrigger = "textChanged";
    firstTextField.bind(options, vm);
    // registering for the TextField text change listener
    firstTextField.on("textChange", (args) => {

        vm.set("tfResult", args.object.text);
    });


    // creating new TextField and binding the secure property
    const secondOptions = {
        sourceProperty: "secure",
        targetProperty: "secure"
    };
    const secondTextField = new textFieldModule.TextField();
    secondTextField.bind(secondOptions, vm);

    stackLayout.addChild(firstTextField);
    stackLayout.addChild(secondTextField);

    page.bindingContext = vm;
}

exports.onPageLoaded = onPageLoaded;

export function onPageLoaded(args) {
    const page = <Page>args.object;
    const vm = new Observable();
    const stackLayout: StackLayout = <StackLayout>page.getViewById("stackLayoutId");

    vm.set("username", "john");

    vm.set("secure", false);
    // changing TextField secure property value on button tap
    vm.set("onTap", (btargs) => {
        const secure = vm.get("secure");
        vm.set("secure", !secure);
        if (secure) {
            vm.set("secureButton", "TextField secure:(OFF)");
        } else {
            vm.set("secureButton", "TextField secure:(ON)");
        }
    });
    // creating new TextField and binding the text property
    const options = {
        sourceProperty: "username",
        targetProperty: "text"
    };
    const firstTextField = new TextField();
    firstTextField.updateTextTrigger = "textChanged";
    firstTextField.bind(options, vm);
    // registering for the TextField text change listener
    firstTextField.on("textChange", (argstf) => {

        vm.set("tfResult", (<TextField>argstf.object).text);
    });


    // creating new TextField and binding the secure property
    const secondOptions = {
        sourceProperty: "secure",
        targetProperty: "secure"
    };
    const secondTextField = new TextField();
    secondTextField.bind(secondOptions, vm);

    stackLayout.addChild(firstTextField);
    stackLayout.addChild(secondTextField);

    page.bindingContext = vm;
