The DataGridColumnStyle contains combobox for a DataGrid on your .Net form. It is not just a dropdown combobox, which appears when a datagrid cell becomes the current cell. This .Net DataGrid DataGridColumnStyle combobox control has the following attractive features:

This combobox DataGridColumnStyle automatically fills the text at the cursor with the value of its dropdown values list. As characters are typed, the 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 DataGridColumnStyle gives you ability to instantly update dropdown values with a really simple and friendly user interface. When you click the additional dropdown button of the combo a dictionary of its list values will be displayed below the combo. You can update values, and insert and delete rows in the dictionary grid.

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 combobox DataGridColumnStyle just as an easy dropdown DataGrid combobox.

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


Syntax
DataGridComboBoxColumn(DataSource, DisplayMember, ValueMember, SearchInList, CaseSensitiveSearch, CallDictionary, DisplayMode, allDictionaryColumns)

Parameters

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

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

ShowDisplayMember - default. DisplayMember will be shown in whole column
ShowValueMember - ValueMember will be shown in whole column
ShowValueMember_and_DisplayMember - ValueMember + DisplayMember will be shown together in a column

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.

DataGridXPButtonColumn allows you to provide the datagrid interface your users are requesting, while supporting the utterly powerful Microsoft .NET DataGrid control. The DataGridXPButtonColumn makes the MS .NET DataGrid control one of the most powerful controls that you ever had used. A RustemSoft DataGridXPButtonColumn column in a .net DataGrid control gives you ability to define custom functionality for items in the grid beyond the edit, delete, select, and hyperlink features of other column types. For example, you can use a DataGridXPButtonColumn to create a "Link to a website" button.
The DataGridXPButtonColumn has a pushbutton-style only. The button captions can be a text read from a database.
DataGridXPButtonColumn control shows a button instead of text, even when the containing cell does not have focus. To switch the feature off change value of ButtonInEachCell parameter to False and only the selected button column's cell will appear as a button. Also you can assign a Title for each button in your button column instead of populating table field's text. Just assign value of PerpetualText property.

When you define a button column, you specify a command associated with the button. The Click event of DataGridXPButtonColumn class occurs when the user clicks the button, the button's command is passed to a container where you can handle it with your custom code.

The DateTimePicker ColumnStyle is used to allow the user to select a date and time, and to display that date/time in your DataGrid.

Syntax
DataGridDateTimePicker()

You have a DataGrid with a DateTime field 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 DataGridDateTimeColumn style can help you design the concept that will resolve your needs.
The DateTime ColumnStyle is used to allow the user to insert formatted date and time, and to display that date/time in your DataGrid.

Syntax
DataGridDateTimeColumn(Format, DefaultValue, DelimiterChar)

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 "/".

This formatted intelligent NumericColumn style 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 numeric column follows the formatting of the original column. If you define specific parameters (MaxLength, DecimalLength,...) for the column 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
DataGridNumericColumn(IntegerOnly, PositiveOnly, DefaultValue, MinValue, MaxValue, MaxLength, DecimalLength)

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).

DecimalLength - as integer, specifies a fixed decimal length. Default is empty numeric (null/Nothing).

This formatted intelligent TextFractionsColumn style control can mask the text fractions. It gives you ability to manage the IP Address, SS#, Phone numbers, etc., and checks the validation, and automatically set the delimiter location.
The TextFractionsColumn style is useful in several situations. For example, this control will automatically format a telephone number so when a user enters their phone number like this:

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
DataGridTextFractionsColumn()

To identify each text fraction you must set values of two-dimensional array where properties of the fractions are stored. The first array's element specifies what characters can be inserted into the fraction. It accepts the following values:
N - numeric characters (0-9) are acceptable only
L - letters (Aa-Zz) are acceptable only
A - alphanumeric characters (Aa-Zz0-9) are acceptable only
P - punctuation characters are acceptable only
S - spaces are acceptable only
Empty - any characters are acceptable
The second array's element specifies overall fraction's length.

DataGrid Check column style accepts and displays true, false values. The RustemSoft DataGridCheckColumn control specifies a column in which each cell contains a check box for representing a Boolean value.
The Check Column in a default state, is used in a similar manner as the standard Microsoft DataGridBoolColumn binding to a boolean datacolumn and displaying a checkbox. Besides using Boolean data type field as a source field you can use also String data type and any Numeric data types source field of your data source DataTable object. At run time, the DataGridCheckColumn contains check boxes in each cell that have two states:

checked: true for Boolean data type
"True" for a String data type
1 for a Numeric data type
unchecked: false for Boolean data type
""(empty string) for a String data type
0 for a Numeric data type
A Click Event is raised when the cell is clicked, passing a System.EventArgs object, you can react to this event in your code.

Syntax
DataGridCheckColumn()

The control creates a column of Labels mapped to DataColumn of type String.

The RustemSoft DataGridLabelColumn provides you with a read-only cell. It gives you ability to set all column desired colors and raises an event when the cell is clicked allowing you to interact to the event in your code.

The DataGridLabelColumn raises a Cell event when the user clicks on a cell you can react to this event in your code.

Syntax
DataGridLabelColumn()

The RustemSoft DataGridTextEditColumn gives you a useful TextEdit Field control, which presents an edit area when user selects a cell of the DataGrid TextEdit Column on .NET DataGrid. When using the TextEdit you are automatically provided with a vertical scrollbar and the ability to put carriage returns in your data using the 'Enter' key. Also all general features, which any typical, contemporary word processor has, are provided. According to the nature of the DataGrid navigation 'Tab' characters are not supported by the DataGridTextEditColumn.
This TextEdit field editor provides more flexibility by updating the TextEdit column to be used in a .NET DataGrid column.

The DataGrid TextEdit Column TextEdit field editor is useful for showing short document contents, like Memos and emails.
The DataGridTextBoxColumn provides several events, that enables you interact the events in your code.

Obviously the DataGridPrint class is not a datagrid column style control. The service class is intended to help you to create a print output based on your datagrid content. The class has been included into assembly since it is build for .NET WinForms datagrid control and very helpful for your .NET datagrid design. It will help you to implement an application with a print preview and a print support.
The DataGridPrint class is used by the Print dialog and Print Preview dialog (on your .NET form) to draw the DataGrid object content that should be printed. An object of the class is used for a .NET PrintDocument object.

Syntax
DataGridPrint(PrintDocument1, DataGrid1, bBlackWhite)

PrintDocument1 - System.Drawing.Printing.PrintDocument reusable object that sends output to a printer
DataGrid1 - System.Windows.Forms.DataGrid object that content you are going to print
bBlackWhite - boolean parameter that defines if you like to use "Black and White" printing mode or you would like to send to printer the real coloring that your datagrid control has currently on your form.
