I have an ItemsControl that I've bound to an IEnumerable. In the DataTemplate, I am creating a CheckBox for each Enum.
For ONE of the Enum's, I want to enable a textbox outside of the ItemsControl if it is checked. How can I do this?

I have a ListBox with ItemsSource bound. If anyone selects a ListBoxItem and presses Enter key, a command should be executed. How could I do this? I have ItemContainerStyle for ListBox and I cannot find a way to set InputBindings through Style.
Any ideas?
You could create an attached helper property which sets the bindings, here would be an example, you then can set that property in the style.
I've ItemsControl that its ItemsSource property bind to some dictionary from code behind. The ItemTemplate is consist of only one button. So, for each item in dictionary it creates button.
My question is how can I set focus to one of these buttons (dynamically)?
Should I use ItemContainerGenerator.ContainerFromItem ?
Any other idea?
Thanks in advance!
Yes, use can ItemContainerGenerator.ContainerFromItem to get a container for your data item, then you will need to find you button inside this container and call Focus() on the button.
OR you can use an attached property to bind IsFocused to a property on your data item. See Set focus on textbox in WPF from view model (C#)
I have a Usercontrol that contains a ListBox (lstClients) and a ComboBox
The ListBox has 2 DataTemplates setup as Resources called "LowDetailTemplate" and "HighDetailTemplate"
I need to be able to switch between the 2 DataTemplates when I change the value in a ComboBox from "Low" to "High" and vice versa. In the SelectionChanged event of the ComboBox I'm guessing I need to change the ItemTemplate of the ListBox but I'm struggling with the code to assign the DataTemplate in code behind. My latest attempt is shown below but it fails at runtime.
lstClients.ItemTemplate = (DataTemplate)this.Resources["LowDetailTemplate"];
It would be easier to define both of the views inside the same data template and then switch which is visible by use of a simple variable. Then your combo box change would just update that simple variable and so cause the view shown for each template instance to change.
I'm still new to WPF, and I'm trying to do something that's beyond my knowledge at the moment.
I have a listbox databinded to the source collection, and a label. I'd like to bind the label's Content value to the listbox's item over which is mouse hovered.
Say I have DataTemplate binded to the class MenuItem:
<DataTemplate DataType="{x:Type local:MenuItem}" x:Key="MenuListTemplate">
Which has member Text. I want my Label to display Text from element which is mouse overed in list. I have the IsMouseOver trigger for my textbox, but have no idea how to bind Label.Content to it.
Any tips?
I don't think that binding can achieve your goal with ease. I think it's easier to do with routed events.
Subscribe to the MouseMove event at the ListBox level. Check if the source of the event is a ListBoxItem, and if it is use this item to update the label.
Is there a way to "hide" the SelectedItem of the DataGrid ?
dataGrid.SelectedItem.Visibility = Visibility.Hidden
Setting the Visibility of "SelectedItem", as you have, would not change the grid - it would be changing the "SelectedItem" property value of the bound object for that SelectedItem, which is not going to affect the grid at all.
In order to change the grid row's visibility, you'll need to change it directly. You can retemplate the DataGrid to change how the selected row is displayed.
For details, see DataGrid Styles and Templates.
