Hi all,

I have 

<ListBox x:Name="lstAllAcct" Grid.Row="1"  ItemsSource="{Binding ExcelData}"/>

<Button x:Name="btnNewSelection" Command="{Binding Path=NewSelectionCmd}">



{Binding ExcelData} is to get accounts from excel sheet to my listbox : done

Now when button btnNewSelection is click I want to get all accounts in that listbox to a string (to construct my query statement)


The code behind for the button:


private RelayCommand _newSelectionCmd;
public ICommand NewSelectionCmd
if (_newSelectionCmd == null)


_newSelectionCmd = new RelayCommand(() => DoSearch(), () => true);

return _newSelectionCmd;


private void DoSearch ()

string strAllAccount =""

(how to I get all items in my listbox to strAllAccount?)

Your help is very much appreciated.
