The RustemSoft.Controls library contains a combobox component for your .Net form. It is not just a dropdown combobox. This .Net 2.0 RustemSoft.Controls RSComboBox control has the following attractive features:

This combobox automatically fills the text at the cursor with the value of its dropdown values list. As characters are typed, the RSComboBox component finds the closest matching item from the list and automatically fills in the remaining characters. Appended characters are highlighted so that they are replaced by any further typing. For this auto-filling feature you can setup the character case sensibility.

This RustemSoft Control gives you ability to instantly update dropdown values with a really simple and friendly user interface. When you click the additional combo dropdown button a dictionary of its list values will be displayed below the combobox. You can update values, and insert and delete rows in the dictionary grid which is filled by data from a related datatable.

The control gives an ability to get a nesting combo box that filters values from a related child table. In a dictionary grid, you can view and edit related data in a child table. In your database a Master table has a one-to-many relationship with a Child table; so for each row of the Master table in Dictionary grid, you or your customer can view and edit the related rows of the Child table in a dictionary grid.

You can turn off all or some of these features and use the RSComboBox just as an easy dropdown RustemSoft.Controls' combobox.

You can set its DataSource, DisplayMember, and ValueMember to bind the combobox to a foreign table.


Syntax
VB: Dim MyRSCombo As RustemSoft.Controls.RSComboBox
C#: RustemSoft.Controls.RSComboBox MyRSCombo;

Parameters

DataSource - a source for RSComboBox control values list as System.Data.DataTable

DisplayMember - field to display in combo as Integer (index of column) or as String (name of table column)

ValueMember - field with values, which binds to RSComboBox as Integer (index of column) or as String (name of table column). Specify the contents of the ValueMember property in cases where you bind data.

SearchInList - identifies if you need auto-fill features as Boolean (default is True)

CaseSensitiveSearch - as Boolean (default is False)

CallDictionary - as Boolean (default is True). If False - the combobox is just a dropdown combobox without the dictionary grid.

allDictionaryColumns - works if CallDictionary is True only. The parameter identifies how many columns you need to see in the called Dictionary grid (default is 0)
You may set the following values:
0 - default. DisplayMember and/or ValueMember fields will be shown in your Dictionary grid.
1 - all related child table's fields will be shown in your Dictionary grid.
2 - all related child table's fields will be shown in your Dictionary grid except relation key fields.

Also you can leave the allDictionaryColumns parameter (define it as null in C# and C++ code) and specify your own columns for the Dictionary datagrid. Please see our samples to learn how to do that.

You have a TextBox object on your .NET Windows Form with a DateTime value that displays the date/time as "2/20/2005 7:00:00 PM". You would like to display only the time in the following format "7:00 PM". You would like to insert a new time in the column or update current time value only. Let us suppose that you are European and would like to see in date field something like "20.02.2005". The RustemSoft DateTime box Control can help you design the concept that will resolve your needs.
The DateTime box control is used to allow the user to insert formatted date and time, and to display that date/time on your .NET 2.0 Form.

Syntax
VB: Dim MyDateTimeBox As RustemSoft.Controls.DateTimeBox
C#: RustemSoft.Controls.DateTimeBox MyDateTimeBox;

Parameters

Format - Various formats may be set. You may use a date/time format (like MMDDYY, MMDDYYYY, DDMMYY, DDMMYYYY, YYYYMMDD, HHMM12, HHMMSS12, HHMM24, HHMMSS24) to enable the date/time inserting and updating. Default is MMDDYYYY.

DefaultValue - any DateTime value. For example, you can set the DefaultValue to today's date. Default is empty DateTime (null/Nothing).

DelimiterChar - a delimiter between date/time fractions (between days and month or hours and minutes). Default is "/".

The RustemSoft TimeUpDown Box represents a Time up-down control that displays Time values. It allows you to show a TimeUpDownBox control on a .NET Form.

The TimeUpDownBox control contains a single Time value that can be incremented or decremented by clicking the up or down buttons of the control in a TimeUpDown Box. You may also enter in a value. The Time display may be formatted by setting the TimeFormat property that can have the following values:
HHMM12
HHMMSS12
HHMM24

Syntax
VB: Dim MyTimeBox As RustemSoft.Controls.TimeUpDownBox

This formatted intelligent Numeric box control can mask the numbers, digits, decimal and checks the validation, and automatically set the delimiter location. You may input any number. If there is a numeric scale defined with the field, it is used to format the display and the input.

Note By default the .NET Numeric box follows the formatting of the original datatable's column. If you define specific parameters (MaxLength, DecimalLength,...) for the box object it will accept them. However if the original DataTable's column could not accept your defined parameters it will ignore your settings. For example, the datatype for an original numeric datatable's field is Integer and you give to the DecimalLength parameter some not zero value. For this case the control will not allow your users to insert decimal values. Please choose appropriate datatypes and column settings.

Syntax
VB: Dim MyNumericBox As RustemSoft.Controls.NumericBox
C#: RustemSoft.Controls.NumericBox MyNumericBox;

Parameters

IntegerOnly - as Boolean. Default is False.

PositiveOnly - as Boolean. Default is False.

DefaultValue - any numeric value. Default is empty numeric (null/Nothing).

MinValue - any floating-point value range minimum of the inserted value. Default is empty numeric (null/Nothing).

MaxValue - any floating-point value range maximum of the inserted value. Default is empty numeric (null/Nothing).

MaxLength - as integer, specifies a fixed length of whole input area. Default is empty numeric (null/Nothing).

123-456-7890
or
1234567890

it will automatically change the numbers in the column text updating box.

Up to 5 text fractions can be defined. By setting the DelimiterChar property up a delimiter symbol for the control can be specified. You can define the overall length of each text fraction and what kind of characters can be inserted in the fraction (alphanumeric, numeric only, etc.).

Syntax
VB: Dim MyFractionBox As RustemSoft.Controls.FractionBox
C#: RustemSoft.Controls.FractionBox MyFractionBox;

To identify each text fraction you must set values of ten properties where settings of the fractions are stored.
