how to create grid lines in list view of windows form while designing
Did you try setting the GridLines property to true?
If this didn't seem to work for you, maybe you need to change the View property to Details, in order to move the list view to the grid mode.

I have a tree view that displays a structure of agenda items. The tree structure is merely for ui and usability purposes. The tree view is “flattened” into a linear list of agenda items. When an item is selected in the tree view, I would like to scroll the corresponding linear list item to the top of the listview.
The items in the listview are custom user controls.
I would like to use an attached behavior since I need to stay within MVVM. I have manly to issues. I need to be able to inject an index into the view and trigger the scroll itself by a command.
Any ideas?
Kind regards
This approach seem feasible but Im not getting how to pass an index to a behavior. https://marcominerva.wordpress.com/2014/09/30/scrolltobottom-behavior-for-listview-in-mvvm-based-universal-windows-apps/

mvvm how to make a list view auto scroll to a new item in a list view
You shouldn't need to deal with an Index if you're using MVVM, just use the selected item instead. Ideally, your TreeView and ListView should be binding to the same items.
I need to build a custom items control in WPF, where the user can drag/drop the items. Normally I would just maintain a list of view models and use a data template to define how the items should be displayed (in this case, a button). But I am concerned that this will make the drag/drop difficult as the ItemsSource objects will be view model objects , not the actual button.
My other potential approach is when an object is added to the ItemsSource, create a button in c# and add it manually, that way I can access the button directly to do drag/drop.
What would your advice be?
I have solved my issue. I found a way to get the control being render from the data template
i want to immitate the behavior of multiselection of items (eg. in a list view) and their appearence in a PropertyGrid. So, obly the same properties are shown and values set in the grid are set on all multiselected properties.
I have created a listview with some datatemplates and have in another listview some data(with databinding). Now i want wo have a multiselection on the listview with the data and have the properties shown in the another listview like in a propertygrid.(explanation: The ProprtyGrid is still not available in WPF and if has not the flexibility of showing data the way i need it)
So, how do i need to prepare my data to be shown in the list propertygrid-multiselection-style? Is that even possible???

I'm not sure if this question is still active, or what not. But I have found a solution that works for me - and I need somewhere to share it.
The first issue you are going to have solve is selecting the items, ie. multi-select. See my tip here that explains how to do that.
Next, I guess its basically binding to listview's selectedItem property and how you want to update your propertyGrid based on changes to the selectedItem prop.
Hope this helps.
I have a treeview with several items in it. How do I force the treeView to select a specific item ? Everytime I try to use any of the "Selected..." property, I get the error that it is read-only and cannot be set either in code or in XAML.
Regards,
You need to create a Selected property on your tree item's ViewModel, and bind to it.
Here is an article that explains how to do it.
Edit. Actually that uses a different way. The article I was thinking of was this one
I'm not quite sure how to go about this so any advice would be much appreciated.
I have a ListView whose default implementation is using with column headers. At runtime in the program I would like to be able to click on a button at runtime to change the view so that the list view loses the GridViewColumn headers and implements a new style using one of my own data template.
Then I would also like the ability to click the button and change the ListView back to a grid view with column headers.
Can anyone point me in the correct direction of how to go about this?
Thanks
Since ListView.View is dependency property, you can bind it to something on your VM via converter.
Microsoft has a sample that demonstrate how to create a ListView control that displays data in multiple view modes, which include the GridView and other custom view modes.
Search for ListView with Multiple Views Sample in the WPF Documentation Sample page.
