Question

I have difficulty in extracting data from datagrid. Since I was using selectionchange event on datagrid. I managed to get the selected row and column index. But I couldn’t find any properties to get the exact data from the datagrid or datagridrow or selectedcells. Hope to get some advice from you guys, cheers.

Bind your DataGrid to an ItemsSource containing your data, and then your SelectedItem will be the item in your ItemsSource.

You had a comment above of using ComboBoxes, so here’s an example:

<DataGrid ItemsSource="{Binding MyData}" AutoGernateColumns="False">
    <DataGrid.Columns>
        <DataGridComboBoxColumn ItemsSource="{Binding Path=DataContext.ComboBoxOptions, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"
                                DisplayMemberPath="Name"
                                SelectedValuePath="Id"
                                SelectedValueBinding="OptionId" />
    </DataGrid.Columns>
</DataGrid>

The DataContext for your DataGrid would contain

ObservableCollection<SomeItem> MyData { get; set; }
ObservableCollection<Option> ComboBoxOptions{ get; set; }

The SomeItem class would have a property of OptionId, and the Option class would have
an Id and Name field.

In this example, when you select an item in the DataGrid the DataGrid.SelectedItem would contain the SomeItem

Remember, in WPF your Data (DataContext) is your application, and your UI elements like ComboBoxes, TextBoxes, DataGrids, etc are all just a pretty interface to let the user interact with your Data
