+Summary: Data Binding isn't working fine with numerical values
+
+When a control property is bound to a data sources's property of numerical
+type, the changes made to the UI should be analized to detect errors in the
+format, and preserve the last valid value.
+
+
+Steps to reproduce the problem:
+1. Compile the sample.
+2. In the first text box, write a non-numerical value.
+3. Change the focus to the second text box (just change the focus).
+
+Actual Results:
+Int32.Parse method throws a FormatException, when the data binding layer
+tries to convert the text in TextBox to the right value for a data source's
+property of Int32 type.
+
+Expected Results:
+Since the new value in the text box is not a valid numerical value, the
+last valid value should be kept.
+
+Additional information:
+Probably this error detection should be done for other types as well...
