BarIndicatorCssClass	A CSS class applied to the bar indicator's inner bar when StrengthIndicatorType=BarIndicator
CalculationWeightings	A list of semi-colon separated numeric values used to determine the weight of password strength's characteristic. Remarks: There must be 4 values specified which must total 100. The default weighting values are defined as 50;15;15;20. This corresponds to password length is 50% of the strength calculation, Numeric criteria is 15% of strength calculation, casing criteria is 15% of calculation, and symbol criteria is 20% of calculation. So the format is 'A;B;C;D' where A = length weighting, B = numeric weighting, C = casing weighting, D = symbol weighting.
DisplayPosition	Positioning of the strength indicator relative to the target control
HelpHandleCssClass	A CSS class applied to the help element used to display a dialog box describing password requirements Remarks: This is used so that the user can click on this image and get a display on what is required to make the password strong according to the current properties
HelpHandlePosition	Positioning of the help handle element relative to the target control
HelpStatusLabelID	Control ID of the label used to display help text
MinimumLowerCaseCharacters	A minimum number of lowercase characters required when requiring mixed case characters as part of your password strength considerations Remarks: Only in effect if RequiresUpperAndLowerCaseCharacters property is true. The default value is 0 which means this property is not in effect and there is no minimum limit.
MinimumNumericCharacters	Minimum number of numeric characters Remarks: If there are less than this property, then the password is not considered strong. If there are equal to or more than this value, then this will contribute 15% to the overall password strength percentage value.
MinimumSymbolCharacters	Minimum number of symbol characters (ex. $ ^ *) Remarks: If there are less than this property, then the password is not considered strong. If there are equal to or more than this value, then this will contribute 15% to the overall password strength percentage value.
MinimumUpperCaseCharacters	Minimum number of uppercase characters required when requiring mixed case characters as part of your password strength considerations. Remarks: Only in effect if RequiresUpperAndLowerCaseCharacters property is true. The default value is 0 which means this property is not in effect and there is no minimum limit.
PreferredPasswordLength	Preferred length of the password Remarks: Passwords could be less than this amount but wont reach the 100% calculation if less than this count. This is used to calculate 50% of the percentage strength of the password Ideally, a password should be 20 characters in length to be a strong password.
PrefixText	Text prefixed to the display text when StrengthIndicatorType=Text
RequiresUpperAndLowerCaseCharacters	Specifies whether mixed case characters are required Remarks: Determines if mixed case passwords are required to be considered strong. If true, then there must be at least one occurrence of mixed case (upper and lower) letters in the password to be considered strong. If there is, this will contribute 20% to the overall password strength percentage value.
StrengthIndicatorType	Strength indicator type (Text or BarIndicator) Remarks: BarIndicator - progress bar indicating password strength Text - low, medium, high or excellent
StrengthStyles	List of semi-colon separated CSS classes that are used depending on the password's strength. Remarks: This property will override the BarIndicatorCssClass / TextIndicatorCssClass property if present. The BarIndicatorCssClass / TextIndicatorCssClass property differs in that it attributes one CSS style to the BarIndicator or Text Strength indicator (depending on which type is chosen) regardless of password strength. This property will cause the style to change based on the password strength and also to the number of styles specified in this property. For example, if 2 styles are defined like StrengthStyles="style1;style2" then style1 is applied when the password strength is less than 50%, and style2 is applied when password strength is >= 50%. This property can have up to 10 styles.
TextCssClass	CSS class applied to the text display when StrengthIndicatorType=Text
TextStrengthDescriptions	List of semi-colon separated descriptions used when StrengthIndicatorType=Text (Minimum of 2, maximum of 10; order is weakest to strongest) Remarks: Example: None;Weak;Medium;Strong;Excellent
