Dynamic Listview content WPF

Question

Hello Everyone I am looking for a way to create a ListView on my page that will change depending on what button is clicked.

For example if the View Users button is clicked I want the list view to show "First Name" Last Name" "Email", if the View Projects button is pushed I want the list view to show "Project Name" "Description"....

All this data is being pulled off a SQL server. I want the user to be basically be able to switch between different SQL statements I am creating via a button click and have the results shown in the ListView.

I am not sure if the ListView is the best option for this or how to approach this. I want to still maintain MVVM while designing this. I am just looking for some input or a point in the right direction.

Thanks!

Try creating a User class. Then when you call your SELECT * from dbo.Users SQL statement and are executing your reader you can simply create a new User object, parse all the sql data into the User object (for example a string for name, datetime for bday, etc...), and store said User object in a List that you created when you ran the sql statement. Then you can write a foreach(User u in ), create a string inside the loop and write the properties to said string, then call ListView.Items.Add(). Just format the string how you wish to achieve the results you desire

What I ended up doing was using a List view style data trigger to switch between two different grid views. In my ViewModel I have a boolean called ViewingProjects that gets set to true when my button is pressed. This switches me between two different item sources that I bind the grid view to, when a button is pressed I call the appropriate GetUser() GetProject() function which updates the observable collection I am bound to and then update the view.
