itemssource

It looks WFP DataGridComboBoxColumn is using a single ItemsSource for all cells in this column. I have a case where the ComboBox items are dependent on the other cell in the same row. I managed to populate the ItemsSource in PreparingCellForEdit event. However, it doesn't work as desired. Initially, all cells in this column is empty. Once I populate the ItemsSource for this column's ComboBox, all related cells (with the same items source) are showing values. However, if I click another type of cell (a different items source is populated), all values disappear and the new type cells show values

I have a datagrid whose ItemsSource binds to a CollectionViewSource . In each column I specify the Path property of the binding to get the specific information to display. What I'd like to do is toggle some of the columns with a checkbox if the user wants more info. To do this, I need to bind the visibility property to the value of the checkbox (with a converter) but I'm pretty sure the data context of the column is interfering with the binding. <DataGrid ItemsSource="{Binding Source={StaticResource cvs}}" ....> <DataGrid.Columns> <DataGridTextColumn Header="First Name" Binding="{Binding Path

I'm writing a custom ItemsControl (a tabbed document container), where each item (tab) can remove itself from the UI when the user closes it. However, I can't remove it directly from the ItemsControl.Items collection, because the items can be databound. So I have to remove it from the ItemsSource , which can be anything ( ICollection , DataTable , DataSourceProvider ...). In the context of my application, I know what the actual type of the ItemsSource will be, but I want that control to be more generic so that I can reuse it later. So I'm looking for a way to remove an item from a data source,

In WPF Databinding, I understand that you have DataContext which tells an element what data it is going to bind to and ItemsSource which "does the binding". But e.g. in this simple example it doesn't seem that ItemsSource is doing anything useful since, what else would you want the Element to do to the DataContext except bind to it ? <ListBox DataContext="{StaticResource customers}" ItemsSource="{Binding}"> And in more complex examples of ItemsSource , you have Path and Source which seems to be encroaching on the territory of DataContext . ItemsSource="{Binding Path=TheImages, Source=

I am new to WPF. I have a ListBox that has its ItemSource set to a instance of WorkItemCollection . (A collection of WorkItem objects.) When the list is displayed it only displays the type of each object (Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItem). Is there a way to make the list display WorkItem.Title? You have two options. The simplest method is to set the DisplayMemberPath property of your ListBox to "Title". If you want to set not only what gets displayed, but the type of control that is used to display it, then you would set the ListBox's ItemTemplate . For what your goal
