When you get a cursor from SelectionSet it is a read only cursor so you cannot do an Update on it.  To do an Update you need to get an Update cursor from the IFeatureClass::Update method (likewise if you want to do an Insert you need an InsertCursor). Also I am not sure how you access your tool but need to be editing when you do an update.  Depending on how you got to the workspace that might be something you have to do in your application Good Luck ...

If you want them to be able to enter multiple criteria than you do not want the query run on the click event of the check box.  You want a button in there the runs the query after all the appropriate checkboxes are selected.  If it is on the chekbox click it will run before they complete all of their selections         <StackPanel x:Name="CheckBoxPanel" Orientation="Vertical" Grid.Column="0" Grid.Row="3" Grid.ColumnSpan="3" AllowDrop="True">             <TextBlock x:Name="QueryData"                                Text="Do you have any special needs for your trip?"                                Foreground="White"                                FontSize="20" FontWeight ="ExtraBold"                                Grid.Row="0"                                                      Margin="15,5,15,1"                                HorizontalAlignment="Center" >             </TextBlock>              <CheckBox                     x:Name="OxygenTank"                     Content="Oxygen Tank"                     Tag="OxyygenTank"/>              <CheckBox                     x:Name="ServiceAnimal"                     Content="Service Animal"                     Tag="ServiceAnimal"/>              <CheckBox                     x:Name="Walker"                     Content="Walker"                     Tag="Walker"/>              <CheckBox                     x:Name="Wheelchair"                     Content="Wheelchair"                     Tag="Wheelchair"/>             <CheckBox                     x:Name="Scooter"                     Content="Scooter"                     Tag="Scooter"/>             <Button Height="30" Width="60" Content="Search" Click="Button_Click"/>         </StackPanel> Also in the code in the post above, the statements are all in the form of if {} else if {} else if {}.  This means that as soon as something is found to be true (a checkbox is checked) none of the other statements are evaluated, which is definitely not the goal.  (Aside: As a general rule, else if {} is not a good construct) Just for fun I threw in a bit of a trick that could help reduce the amount of code.  I added a Tag to each button that contains the field name.  Tag is basically a property that is on every control to have some place to put some extra info if you wanted.  Also I named the StackPanel so that it can be used in the code as a parent container of all our checkboxes To build the Where clause a variable is introduced to hold the Where string as all the checkboxes are looked at, creatively this was named where 🙂           private void Button_Click(object sender, RoutedEventArgs e)         {            //Setup stuff from before....              string where = null;              //This uses a foreach with a little Linq, it will look at every Child of the StackPanel and if it is a CheckBox that is Checked then go into the loop             foreach (CheckBox checkBox in CheckBoxPanel.Children.OfType<CheckBox>().Where(checkBox => checkBox.IsChecked == true))             {                 AppendWhere(ref where, checkBox);             }              query.Where = where;              queryTask.ExecuteAsync(query);         }          private void AppendWhere(ref string where, CheckBox checkBox)         {             string checkBoxQuery = checkBox.Tag + " = '" + checkBox.Content + "'";              if ( where == null )             {                 where = checkBoxQuery;             }             else             {                 where += " OR " + checkBoxQuery;             }         } The main part is building the Where clause in AppendWhere.  The existing where is passed in (as a reference), if it is null than no query condition has been added to the query so it just starts it out with fieldname = fieldvalue.  If the value of where is not null, that means a condition has been added and so an OR needs to be added before the next condition. Also using the little trick with the Tag and Content properties the entire string does not need to be written out.  I am a terrible typer so believe that reducing the amount of code that needs to be written to accomplish a task is good Good luck ...
