Ok after doing reverse engineering and a little pixie dust of reflection, one can do this operation on SelectedCells (at any point) to get all (regardless of selected on one row or many rows) the data from one to many selected cells:

MessageBox.Show(

string.Join(", ", myGrid.SelectedCells
                        .Select(cl => cl.Item.GetType()
                                             .GetProperty(cl.Column.SortMemberPath)
                                             .GetValue(cl.Item, null)))

               );

I tried this on text (string) fields only though a DateTime field should return a value the initiate ToString(). Also note that SortMemberPath is not the same as Header so that should always provide the proper property to reflect off of.

<DataGrid ItemsSource="{Binding MyData}"                      
          AutoGenerateColumns="True"
          Name="myGrid"
          IsReadOnly="True"
          SelectionUnit="Cell"
          SelectionMode="Extended">

If SelectionUnit  Cell  try this       string cellValue   GetSelectedCellValue      Where       public string GetSelectedCellValue                 DataGridCellInfo cellInfo   MyDataGrid SelectedCells 0           if  cellInfo    null  return null           DataGridBoundColumn column   cellInfo Column as DataGridBoundColumn          if  column    null  return null           FrameworkElement element   new FrameworkElement     DataContext   cellInfo Item            BindingOperations SetBinding element  TagProperty  column Binding            return element Tag ToString            Seems like it shouldn t be that complicated  I know     Edit  This doesn t seem to work on DataGridTemplateColumn type columns  You could also try this if your rows are made up of a custom class and you ve assigned a sort member path       public string GetSelectedCellValue                 DataGridCellInfo cells   MyDataGrid SelectedCells 0            YourRowClass item   cells Item as YourRowClass          string columnName   cells Column SortMemberPath           if  item    null    columnName    null  return null           object result   item GetType   GetProperty columnName  GetValue item  null            if  result    null  return null           return result ToString

If you are selecting only one cell then get selected cell content like this  var cellInfo   dataGrid1 SelectedCells 0    var content   cellInfo Column GetCellContent cellInfo Item     Here content will be your selected cells value  And if you are selecting multiple cells then you can do it like this  var cellInfos   dataGrid1 SelectedCells   var list1   new List lt string gt      foreach  DataGridCellInfo cellInfo in cellInfos        if  cellInfo IsValid                  GetCellContent returns FrameworkElement         var content  cellInfo Column GetCellContent cellInfo Item               Need to add the extra lines of code below to get desired output            get the datacontext from FrameworkElement and typecast to DataRowView         var row    DataRowView content DataContext             ItemArray returns an object array with single element         object   obj   row Row ItemArray             store the obj array in a list or Arraylist for later use         list1 Add obj 0  ToString

Please refer to the DataGrid Class page on MSDN  From that page   Selection By default  the entire row is selected when a user clicks a cell in a DataGrid  and a user can select multiple rows  You can set the SelectionMode property to specify whether a user can select cells  full rows  or both  Set the SelectionUnit property to specify whether multiple rows or cells can be selected  or only single rows or cells  You can get information about the cells that are selected from the SelectedCells property  You can get information about cells for which selection has changed in the SelectedCellsChangedEventArgs of the SelectedCellsChanged event  Call the SelectAllCells or UnselectAllCells methods to programmatically select or unselect all cells  For more information  see Default Keyboard and Mouse Behavior in the DataGrid Control   I have added links to the relevant properties for you  but I m out of time now  so I hope you can follow the links to get your solution

you can also use this function    public static void GetGridSelectedView out string tuid  ref DataGrid dataGrid string Column                try                          grid selected row values             var item   dataGrid SelectedItem as DataRowView              if  null    item  tuid   null              if  item DataView Count  gt  0                                tuid    item DataView dataGrid SelectedIndex  Column  ToString   Trim                              else   tuid   null                      catch  Exception exc    System Windows MessageBox Show exc Message   tuid   null

I struggled with this one for a long time   Using VB NET  Basically you get the row index and column index of the selected cell  and then use that to access the value   Private Sub LineListDataGrid SelectedCellsChanged sender As Object  e As SelectedCellsChangedEventArgs  Handles LineListDataGrid SelectedCellsChanged      Dim colInd As Integer   LineListDataGrid CurrentCell Column DisplayIndex      Dim rowInd As Integer   LineListDataGrid Items IndexOf LineListDataGrid CurrentItem       Dim item As String      Try         item   LLDB LineList Rows rowInd  colInd      Catch         Exit Sub     End Try  End Sub   End Class

Xaml Code  lt DataGrid Columns gt   lt DataGridTextColumn Binding   Binding Path Date  Converter  StaticResource    dateconverter   Mode OneWay   Header  Date  Width  100   gt   lt DataGridTextColumn Binding   Binding Path Prescription   Header  Prescription  Width  900   gt   lt  DataGrid Columns gt     C  Code  DataRowView row    DataRowView grid1 SelectedItem   MessageBox Show row  Prescription   toString           row  Date   toString       As WPF provides binding in DataGrids  this should be rather transparent  However  the following method only works  if you have used SQLDataAdapter and provided a binding path to your DataGridColoumns  For eg  Let s say the above datagrid is named grid1  which has auto generate columns set to false  and is using binding to bind column names to Headers  In this case  we use the  row  variable of type  DataRowView  and store the selected row in it  Now  use your Binding Paths  and reference individual columns of the selected row  Hope this helps  Cheers   PS  Works if SelectionUnit    Row
