WPF C# DataGrid edit cell

Question

I have a problem with editing cells in a DataGrid.

When I double click in a cell, an exception is raised - InvalidOperationException 'EditItem' is not allowed for this view

I'm looking for the easiest way to edit cell in datagrid.

XAML-------------------------------------------------------------------------------XAML

<DataGrid x:Name="ZdarzeniaDataGrid" AutoGenerateColumns="False" CanUserAddRows="True" HorizontalAlignment="Left" Margin="71,398,0,0" VerticalAlignment="Top" Height="279" Width="1119">
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding IdZdarzenia}" Header="Id Zdarzenia" Width="100"/>
                <DataGridTextColumn Binding="{Binding Gospodarze}"  Header="Gospodarze" Width="100"/>
                <DataGridTextColumn Binding="{Binding Goście}"  Header="Goście" Width="100"/>
                <DataGridTextColumn Binding="{Binding Kurs1}" Header="Kurs 1" Width="100"/>
                <DataGridTextColumn Binding="{Binding Kurs0}" Header="Kurs 0" Width="100"/>
                <DataGridTextColumn Binding="{Binding Kurs2}" Header="Kurs 2" Width="100"/>
                <DataGridTextColumn Binding="{Binding Kurs10}"  Header="Kurs 10" Width="100"/>
                <DataGridTextColumn Binding="{Binding Kurs20}" Header="Kurs 20" Width="100"/>
                <DataGridTextColumn Binding="{Binding Kurs12}" Header="Kurs 12" Width="100"/>
                <DataGridTextColumn Binding="{Binding DataZdarzenia}" Header="Data Zdarzenia" Width="100"/>
             </DataGrid.Columns>
        </DataGrid>

ZdarzeniaDataGrid.Items.Add(
    new { IdZdarzenia = napis.ItemArray.GetValue(0).ToString(),
          Gospodarze = napis2.ItemArray.GetValue(0).ToString(), 
          Goście = napis3.ItemArray.GetValue(0).ToString(),

          Kurs12 = napis.ItemArray.GetValue(8).ToString(), 
          DataZdarzenia = napis.ItemArray.GetValue(9).ToString() 
    });

Create class with all the properties defined and set/bind the ItemsSource of Datagrid to the list of Data class.

public class Data
    {
        public string    IdZdarzenia {get;set;}
         public string Gospodarze {get;set;}
        public string Goście {get;set;}
        public string Kurs1 {get;set;}
        public string Kurs0 {get;set;}
        public string Kurs2 {get;set;}
        public string Kurs10 {get;set;}
        public string Kurs20 {get;set;}
        public string Kurs12 {get;set;}
        public string DataZdarzenia { get; set; }
    }

Setting ItemSource

    List<Data> dataSource = new List<Data>();
    dataSource.Add(new Data()
    {
                        IdZdarzenia = "a",
                        Gospodarze = "d",
                        Goście = "f",
                        Kurs1 = "g",
                        Kurs0 = "r",
                        Kurs2 = "gs",
                        Kurs10 = "sd",
                        Kurs20 = "sds",
                        Kurs12 = "sdss",
                        DataZdarzenia = "eeee"});
    ZdarzeniaDataGrid.ItemsSource = dataSource;

this should fix your problem.
