queue fifo datagrid observablecollection wfp

I tried changing the binding of the column from Category to Category/, which partially works: it only shows the first value of the Category collection instead of all of them, which is where I'm stuck at the moment. When I run this, the DataGrid only shows one row in the column, it's text being '(Collection)'. Am I totally off with this approach?ġ) Created a Model class which exposes ObservableCollection properties public class AttributeListItems : ObservableObjectĢ) Created a property of ObservableCollection on my ViewModel: private ObservableCollection gridItems ģ) On the setter of my SelectedAttribute property of my ViewModel (which is when I want GridItems to be repopulated) I added this: gridItems.Clear() įileValue = selectedAttribute.FileValues }Ĥ) And on my View I set the ItemsSource of the DataGrid to GridItems and the binding of it's column to Category, as such: The (Of T) class inherits from Collection (Of T), which is the base class for generic collections, and implements both the INotif圜ollectionChanged and INotifyPropert圜hanged interfaces. bind the ItemsSource of my DataGrid to GridColumnsĭataGridColumn to each ObservableCollection in GridColumns.This is especially useful for UIs implemented using WPF, because esentially, when an object is. What makes ObservableCollection special is that it 'tells' observers when a new object is added or when an object is removed.

• create an ObservableCollection> (let's name it GridColumns) property on my ViewModel containing each ObservableCollections I need The ObservableCollection class is a collection type (like List) which means that it holds objects of a given type T.

My question is this: Assuming that I have several ObservableCollection of the exact same count/length, is it possible to bind one ObservableCollection per column? My approach so far has been this: I have a ObservableCollection and want to bind it to a DataGrid. I have a DataGrid in my View, which I have bound the ItemsSource to an ObservableCollection in the ViewModel.

That approach also introduces a new Model class which makes it a problem for TwoWay binding with the actual Model class I need to keep in sync with my View. I am pretty new to WPF MVVM, so pardon me if I understood MVVM concepts wrongly. I've already asked something similar and received a very good answer but the problem with that approach is that items get added in the DataGrid one row at a time.

I'm trying to bind each DataGridColumn of a DataGrid(with AutoGenerateColumns set to False) to one ObservableCollection per column. What about sorting the data using LINQ on the different collection: var collection new List () //add few BarData objects to collection // sort the data using LINQ var sorted from item in collection orderby item.StartData select item // create observable collection var oc new ObservableCollection (sorted) This worked.
