I am making a simple windows forms application. In my listview i want to display three things; date, time and description. I am now doing it like this:
task = date + time + description; (task, date, time, description are all strings).
which give the result:
But what i want is to make these strings to display below the different categories, something like this:
How would go about formatting the 3 strings (date,time,desciption) into one (task) so that they display as in picture two?
Here's a bit of an expanded example for you.
While you may find a way to concatenate the strings and then space them properly by displaying them in something other than a listview, a listview is going to be your best option.
Your code will look something akin to this:
public partial class MainWindow : Window { //Your data private string date = "2016-04-04"; private string time = "20:20"; private string description = "poop"; //Declare a list public List<object> myList { get; set; } public MainWindow() { InitializeComponent(); DataContext = this; //Instantiate your list myList = new List<object>(); //Make a new object var listObject = new { newDate = date, newTime = time, newDescription = description }; //Add that object to your list myList.Add(listObject); } } And your XAML to display your results:
<Window x:Class="WpfApplicationTestApp.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <ListView x:Name="listView" ItemsSource="{Binding myList}"> <ListView.View> <GridView> <GridViewColumn Header="Date" DisplayMemberBinding="{Binding newDate}"/> <GridViewColumn Header="Time" DisplayMemberBinding="{Binding newTime}"/> <GridViewColumn Header="Description" DisplayMemberBinding="{Binding newDescription}"/> </GridView> </ListView.View> </ListView> </Grid> </Window> Concatenating items with + will just perform normal string concatenation, which is why you get everything in a single lump.
To do what you ask you have to add a new ListViewItem where you specify a string array in the constructor. Each array element represents a column in the ListView: {column 1, column 2, column 3, etc...}
For example:
ListView1.Items.Add(new ListViewItem(new string[] {date, time, description})); MSDN Documentation for the ListViewItem(string[]) constructor: https://msdn.microsoft.com/en-us/library/faw83h4f(v=vs.110).aspx
You need to set View:Details from ListView properties to give a grid-style look. When you create a ListItem, it is treated as the data of first column and subsequent SubItems are treated as extra columns for that particular ListItem. Try this example.
ListViewItem lvi; for (int i = 0; i < 10; i++) { lvi = new ListViewItem(); lvi.Text = "first column"; lvi.SubItems.Add("second column"); lvi.SubItems.Add("third column"); listView1.Items.Add(lvi); } 
TextBoxcontrol? AListViewwith 3 columns might be better and easier to format.taskis a single string. But if you have three separate values and want to display them in column/tabular format, then it would make more sense to create an object containing those three values and bind aListVieworGridViewor something like that to a collection of those objects.
