picker

问题 I've been looking on forums and internet about a custom picker on C#, I have a picker already functional, but some of my research throw me that you are only able to select 1 item of the custom Picker, this is the code im using to deploy the picker. Picker <custom:CustomPicker x:Name="pickerCategories" ItemsSource="{Binding listCategoriesName}" SelectedIndex="{Binding SelectedCategory}" SelectedIndexChanged="pickerCategories_SelectedIndexChanged" Grid.Column="1" BackgroundColor="White"/> the

问题 I have designed a picker using react native, and I'm trying to style it using styles.XML BUT its not working. I want my drop down items to wrap in second line when the length of the text exceeds the width. class PickerExample extends Component { state = {link: ''} updateUser = (link) => { this.setState({ link: link }) } render() { return ( <View> <Picker selectedValue = {this.state.user} onValueChange = {this.updateUser}> <Picker.Item label = "25 best small-business apps in 2018 - nerdwallet"

问题 This is going to be a very targeted question , as its for people that have actually used the UIActionSheetPicker before. I used it in my iphone applications and everything worked great , but now that i tried to implement it on my ipad i experienced some problems. The main problem is that on ipad the picker appears as a "bubble" or "info window" if you prefer , which points at the spot where it was called , like a button a text field etc. Below is an example of it : You can see that the "info

问题 I have a Picker Element in a VStack, but when its content changes by adding a new Element, the Picker does not refresh. After hiding and showing the Picker, the new Element is visible. Does anybody have any idea how to refresh the content of a Picker, without needing to hide / show it? You can reproduce this by creating a new SwiftUI project and copying the following code instead of the "ContentView" struct. class ContentModel { @Published var pickerData: [String] = ["1"] func addPickerData()

问题 I have a weird issue when displaying a DatePicker - Time mode on RTL. Im displaying the date picker programmatically. Minutes should be on the right side, and hours on the left, and on the following image you can see it's flipped: It happens on iOS 9 and above. The code I'm using: UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height+44, self.view.frame.size.width, 216)]; datePicker.tag = tag; [datePicker setSemanticContentAttribute

问题 I have searched for simple examples of using a picker without any luck. I would like to have my picker pull from a set of strings for the user to choose from, but I can not seem to even get the following to display. Long now = new Date().getTime(); Date date = (Date) Display.getInstance().showNativePicker(Display.PICKER_TYPE_DATE, cal, now, null); edit : added code block 回答1: You should use the Picker class and not that API directly. Native picker is only supported for some specific types of

问题 I'm using React Native with NativeBase and would like to make the labels of my Picker more complicated than just one plain string of text. But is it even possible to pass elements as the label, say multiple child elements wrapped in a single top-level element? Or do Pickers only support plain text as labels? As requested by bennygenel, here's a version of what I've tried: export default class ThingPicker extends React.Component { render() { const { initialThing, things, onThingChanged, } =

问题 Stackoverflow is awesome! I just posted a question and it was answered by the community within minutes and a working answer was obtained! I have another question about a custom color picker. I know there are many color picker out there but it is just too complicated to use. I need a simpler one. So I decided to create a simple 4x4 pallet of predefined color. The pallets are formed using div with different background color under a div-class named 'supercolor'. <div class="supercolor" > <div

However I want to be able to disable specific dates.
