Assuming you are using integers then:

int value = 0;
if(!Int32.TryParse(strInput, out value))
{
    // Validation failed - show error or feedback to user
}
else
{
    // Validation successful
}

For doubles, replace Int32.TryParse with Double.TryParse etc.

There is probably some fancy WPF way to do this as well (as indicated by V4Vendetta’s comment).
