I have a XAML page in Xamarin Forms. I create a Grid in code behind dynamically,after loading my data. After creating the Grid I need my ScrollView to scroll to the bottom of the page, how? How can I load my grid without scrolling of it ...?
I use
scroll.ScrollToAsync(lastLabel, ScrollToPosition.End, true)
but I do not get any result.
Multiple ScrollView is not working on my content page Xamarin forms.so how to solve this?
i added two scrollviiew in my content page,but the second one is not scrolling.
Do not put a ListView inside a ScrollView.
Avoid placing a ListView inside a ScrollView for the following reasons:
The ListView implements its own scrolling.
The ListView will not receive any gestures, as they will be handled
by the parent ScrollView.
The ListView can present a customized header and footer that scrolls
with the elements of the list, potentially offering the functionality
that the ScrollView was used for. For more information see Headers
and Footers.
If you need more ListView on some Page you should use one ListView with Group.
I have a ListView loaded with items.
When I update the model and try to re-bind the ItemsSource the ListView scrolls to the default position.
I there a way to prevent the ListView from scrolling when re-binding the data or scroll to the previous position.
I am using ObservableCollection for the list.
In my Xamarin forms application, there are multiple ListView controls inside a ScrollView. But in android the scrolling is not working for ListView. Is there any alternative solution?
You SHOULD NOT include ListViews into ScrollView as it system will confuse scrolling behavior of those two.
You need to redesign your page with this in mind.
Example:
1) Use ListViews inside StackLayout
2) Use TableViews inside ScrollView
You can simply do with set 'NestedScrollingEnabled' property true for native side.
For xamarin forms you can create a custom renderer and set 'NestedScrollingEnabled' property true
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.ListView> e)
{
base.OnElementChanged(e);
if (e.NewElement != null)
{
var listView = this.Control as Android.Widget.ListView;
listView.NestedScrollingEnabled = true;
}
}
ListView implements its own scrolling that might conflict with the ScrollView.
If you need to be able to scroll both lists in the same ScrollView you could for example create custom views (instead of using cells), placing them in a StackLayout inside a ScrollView
More about ListView performance, they even explain why you shouldn't place a ListView inside a ScrollView
Have you looked into using one listview with groups instead of multiple listviews?
I use any row of grid it will fix to that height & listview will not scroll
I want to create custom expandable listview using animation effect in android. when i click on layout some imageview child are show and click on other layout show other child ...
