How to add a row to a DataGrid in WPF?

Question

I'm trying to add a row in a DataGrid. I want each item to be a string. This is what I've tried:

string[] testRow = { "hi", "h2", "h3", "h4" };
myDataGrid.Items.Add(testRow );

After doing some research I tried making the items ListBox items and tried this:

ListBoxItem user = new ListBoxItem();
user.Content = "hi";

ListBoxItem bname = new ListBoxItem();
bname.Content = "hi2";

ListBoxItem city = new ListBoxItem();
city.Content = "hi3";

ListBoxItem text = new ListBoxItem();
text.Content = "hi4";

ListBoxItem[] row = { user, bname, city, text };

ListBoxItem[] row = { user, bname, city, text };
myDataGrid.Items.Add(row);

Then after more research I tried using DataGridRow but no success either...

DataGridRow rowt = new DataGridRow();

I have 4 data columns. My columns are defined as DataGridTextColumns. My rows add successfully, but the results are just blank:

What the heck am I doing wrong?

Answer 1

Here i noticed first is DataGrid name is wrong myDataGrid and coming to displaying empty row u set the binding to null so. its displaying empty so and if u wana bind array u can use binding like this

 <DataGrid x:Name="myDataGrid"  HorizontalAlignment="Left" Height="579" VerticalAlignment="Top" Width="611" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible" AutoGenerateColumns="False">


 <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding [0]}" ClipboardContentBinding="{x:Null}" Header="User Name"/>
            <DataGridTextColumn Binding="{Binding [0]}" ClipboardContentBinding="{x:Null}" Header="Business"/>
            <DataGridTextColumn Binding="{Binding [0]}" ClipboardContentBinding="{x:Null}" Header="City"/>
            <DataGridTextColumn Binding="{x:Null}" ClipboardContentBinding="{x:Null}" Header="Text"/>
        </DataGrid.Columns>
    </DataGrid>




string[] testRow = { "hi", "h2", "h3", "h4" };
            myDataGrid.Items.Add(testRow);

note u can just use ItemsSource To bind a entire collection

Class

public class Foo
{
    public string UserName { get; set; }
    public string Business { get; set; }
    public string City { get; set; }
    public string Text { get; set; }

    //Our List
    public static List<Foo> myList = new List<Foo>()
    {
        new Foo() { UserName = "Username1", Business = "Business1", City = "City1", Text = "Text1" },
        new Foo() { UserName = "Username2", Business = "Business2", City = "City2", Text = "Text2" },
        new Foo() { UserName = "Username3", Business = "Business3", City = "City3", Text = "Text3" },
        new Foo() { UserName = "Username4", Business = "Business4", City = "City4", Text = "Text4" },
        new Foo() { UserName = "Username5", Business = "Business5", City = "City5", Text = "Text5" },
        new Foo() { UserName = "Username6", Business = "Business6", City = "City6", Text = "Text6" }
    };
}

DataGrid Be carefull while binding.

    <DataGrid x:Name="myDataGrid" AutoGenerateColumns="False" IsReadOnly="True">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding UserName}" ClipboardContentBinding="{x:Null}" Header="User Name"/>
            <DataGridTextColumn Binding="{Binding Business}" ClipboardContentBinding="{x:Null}" Header="Business"/>
            <DataGridTextColumn Binding="{Binding City}" ClipboardContentBinding="{x:Null}" Header="City"/>
            <DataGridTextColumn Binding="{Binding Text}" ClipboardContentBinding="{x:Null}" Header="Text"/>
        </DataGrid.Columns>
    </DataGrid>

The code for setting itemssource of datagrid.

myDataGrid.ItemsSource = Foo.myList;
