WP (ie. equivalent function to BindingOperations.ClearBinding())?
Thanks for any help...

A:

As it is declared in FrameworkElement.SetBinding method:

Note  Calling the SetBinding method and passing in a new Binding object won't necessarily remove an existing binding. Instead, you should first call the DependencyObject.ClearValue method, then call SetBinding.

So you can change your code like following:
lblTotal.SetBinding(TextBlock.TextProperty, new Binding() { Path = new PropertyPath("Subtotal"), Source = Order, Mode = BindingMode.OneWay });
lblTotal.ClearValue(TextBlock.TextProperty);
lblTotal.SetBinding(TextBlock.TextProperty, new Binding() { Path = new PropertyPath("FinalTotal"), Source = Order, Mode = BindingMode.OneWay });

After this your code should be able to work. For more info, please see Remarks of FrameworkElement.SetBinding and also BindingOperations.SetBinding.

 Q:

How to know hbase server is running or not

I am new to Hbase. 
I have to trigger an email when hbase goes down on the cluster.
Command sudo -u hbase jps gives the process of hbase. 
Please suggest on how to do.

A:

Write a shell script to run on schedule. 
This script will trigger jps command on path \hbase\bin.
Your shell script will start with something like this: 
jps > something.txt
....
....
Place a check in the script i.e. if the result of this jps command returns HMaster & HRegionServer process names then it means HBase is not down. In case any of the process is missing then HBase is down, hence you can trigger mail through your script.

 A: 

 As it is declared in FrameworkElement. SetBinding method acting: 

 notice   call the SetBinding method and legislate in a raw Binding object won't necessarily murder an exist binding. alternatively, you should first call the DependencyObject. ClearValue method acting, then call SetBinding. 

 So you can change your code like following: 
 lblTotal. SetBinding(TextBlock. TextProperty, newfangled Binding () { Path = new PropertyPath("Subtotal "), Source = Order, Mode = BindingMode. OneWay }); 
 lblTotal. ClearValue(TextBlock. TextProperty); 
 lblTotal. SetBinding(TextBlock. TextProperty, new Binding () { Path = new PropertyPath("FinalTotal "), Source = Order, Mode = BindingMode. OneWay }); 

 After this your code should be able to exploit. For more info, please see Remarks of FrameworkElement. SetBinding and also BindingOperations. SetBinding.

 Your shell script will start with something like this:
