i have a main view with a combo box and its controller, and a second view which gets loaded when a button is clicked on the main view.
the second view contains a button and a label and has its different controller.

I have a list of items. First I select an item from list then save it in local db. Now I want that when user open app next time. The save item should be default selected in the list. But no item is selecting default when user comes next time.
How is it possible in xamarin.forms to select an item default selected in listview?
You can set the Listview Selected Item in your code behind.
Assuming you have Binded your ItemsSource, you just need to get the object you want to set as selected and do this:
ListviewItems.SelectedItem = YourCollection[YourIndex];
I have a list of items with Actions drop-down for each item in the left-section of page. I also have a right rail which displays a different component based on action type selected. I'm using aux-route to accomplish this.
One of the Action the user can take is "edit" where in a form is displayed to edit the metadata of the list item. While editing, user can click on + button next to some of the input field to add another input field dynamically.
Now my problem is, when the edit-form is open for a list item and I click edit on another item in the list, I wanted my edit-component to be re-instantiated.
Because the aux-route is same for all the list items for edit-action, edit-view is not instantiated once again. Is there a way to achieve it?
Right now fixed it with RouteReuseStrategy
I have a grid where a button on each row deletes the row upon clicking (with a confirmation), but when the button is clicked, the row is also selected, performing the actions in onRowClick(..) method together.
How can I have the button such that clicking it does not results in selecting the row item?
The click handler for your button should call DomEvent.stopEvent. The doc (2.2.4) is here: http://www.sencha.com/gxtdocs/#com.extjs.gxt.ui.client.event.DomEvent-stopEvent%5B0%5D
