I waited a while but got no answer so I solved the problem by having a helper function in the nested control to enable to set the property at runtime.

    public void SetCounterType(integer countertype) {     //after checking that countertype is a valid value       m_countertype = countertype;     } 

then in the constructor for IntervalEdit:

    public IntervalEdit(Context context, AttributeSet attrs) {       TypedArray array = context.obtainStyledAttributes(attrs, R.styleable.IntervalEdit, 0, 0);     //other attributes read here       m_counterstyle = array.getInt(R.styleable.IntervalEdit_counterstyle, R.integer.counter_simple);       (ThirtySecondIncrement)findViewById(R.id.tsi).SetCounterStyle(m_counterstyle); 

The SetCounterStyle function in the first custom control only sets the variable and doesn’t force a redraw enabling me to call it from within the including custom control’s constructor. Any, that’s how I solved it.

If you would like to open a servlet with javascript without using ‘form’ and ‘submit’ button, here is the following code:

var button = document.getElementById("<<button-id>>"); button.addEventListener("click", function() {   window.location.href= "<<full-servlet-path>>" (eg. http://localhost:8086/xyz/servlet) }); 

Key:

1) button-id : The ‘id’ tag you give to your button in your html/jsp file.

2) full-servlet-path: The path that shows in the browser when you run the servlet alone

MAUI is the next generation of Xamarin Forms with broader platform support. The first preview will be available in .NET 5 in Nov 2020, and the first production release will come with .NET 6 in Nov 2021.

Xamarin Forms will be supported for one year after MAUI is introduced in 2021, then will be deprecated in favor of MAUI.

You could do it like this. thang.json is a file with json you provided.

        var json = File.ReadAllText("thang.json");         var deserialized = JsonConvert.DeserializeObject<dynamic>(json);          if (new[] {"PSTN", "UIFN", "TS", "RS", "TF"}.Contains((string) deserialized.Phone))         {             Console.WriteLine(deserialized[(string)deserialized.Phone]);         } 

This will be a part of your view, such as Index.csthml. With all due respect, I would suggest reviewing ASP.NET Core MVC training videos from YouTube. There are several good ones that help explain the basics.

If one is getting this message during saving or compiling the build, just close all the files and then open any file to compile and save.

For me the reason was that I had rename the file and old file was still open.

and thanks a lot for your response,

I do like that but unfortunately it does not work yet the update has not done

    @foreach (var item in Model.bananes)     {     <div class="col-md-4">                <form asp-action="ViewEdit"  method="post">              <div asp-validation-summary="ModelOnly" class="text-danger"></div>                          <input type="hidden" [email protected](modelItem => item.id)>              <div class="form-group">                 <label asp-for="@item.Name" class="control-label"></label>                 <input class="form-control" value="@Html.DisplayFor(modelItem => item.Name)">               </div>             <div class="form-group">                 <label asp-for="@item.Color" class="control-label"></label>                 <input class="form-control" value="@Html.DisplayFor(modelItem => item.Color)">               </div>             <div class="form-group">                 <label asp-for="@item.BananeP" class="control-label"></label>                    <input class="form-control" value="@Html.DisplayFor(modelItem => item.BananeP)">              </div>              <div class="form-group">                 <input type="submit" value="save" class="btn btn-info text-white " />                              </div>         </form>     </div>}  public IActionResult ViewEdit( [Bind("id,Name,Color,BananeP ")] Banane item)         {                                 _context.Update(item);                       _context.SaveChangesAsync();                                    return RedirectToAction("Index");} 

Assuming your tab content is a type TabContent with a property Header and you bind your items via the ItemsSource property, you can do this.

tabControl.SelectedItem = TabControl.Items.OfType<TabContent>().SingleOrDefault(ti => ti.Header.Equals(myHeader)); 

If you directly assign TabItems to your TabControl, you can do this.

tabControl.SelectedItem = tabControl.Items.OfType<TabItem>().SingleOrDefault(ti => ti.Header.Equals(myHeader)); 

Since both examples use Linq for convenience, be sure to import it with using System.Linq;. The OfType<T>() method will filter the items for a specific type and SingleOrDefault() will return a single element that matches the criteria or null, which would mean that no tab item is selected.

I think the problem might be with your if statement in updatePost function if (isset($_POST['featured_image'])) {. Change this like in createPost function

$featured_image = $_FILES['featured_image']['name']; if (empty($featured_image)) {  ... }
