Hi,

Im testing the SegmentedControl, but the nice animation that I see in the demo app is not happening in my app? What am I missing?

 

 

<telerikInput:RadSegmentedControl x:Name="segmentControl"
                                  HeightRequest="60"
                                  VerticalOptions="Start" AutomationId="MenuSegmentedControl">

Hi,

I have a Picker inside a Popup. I want to open the picker from the code. Usually I would call ".Focus", but it gives an error:

 

System.ObjectDisposedException: Cannot access a disposed object.

Object name: 'Xamarin.Forms.Platform.Android.AppCompat.PickerRenderer'.

(The same happens if I try to set focus to an Entry.)

Please help!

 

Best regards,

Michael

I don't found any example about deleting operation. How i can remove an item row from gridview itemSource?

I found Remove commands, but how i can get the type object to remove?

 

Example :

model :

 

public class City
{
    public City(string name, int population)
    {
        this.Name = name;
        this.Population = population;
    }
 
    public string Name { get; set; }
    public int Population { get; set; }
}

 

I expected that i can pass myGrid.SelectedItem to Remove method, but dosen't work because Remove wants another object type. I'm sorry but is first time that i use Telerik object, and i don't found an example about delete on Xamarin.Forms Data Grid doumentation or in SDK example.

In an accordion on Xamarin try to hide an AccordionItem because in some cases there nothing to show. I added a binding to IsVisible on the AccordionItem and that hides the item but leaves an empty space. So, it's only invisible, but it is still there.

is there a way to hide AccordionItems, where the empty space is collapsed?

 

Kind regards,

Kees Alderliesten

When I tap on cell I need to change the cell color, but when I double tap on the cell I need to show the modal window with a custom data.

The problem is that when I double tap on the cell, the cell tap command also is executed.

How I can prevent executing Cell Tap command when I double tap on the cell?
