Class: Cell

Cell(oItem, oColumn)

new Cell(oItem, oColumn)

The Cell object defines a cell within the control. The cell is the intersection of an Item with a Column. The Cell(item,column) method returns the cell based on the item and column. The Cell(id) method of the Item object gets the item's cell giving the column's index, identifier/key/caption or reference.

Every option of the CellOptions type has associated a property of the Cell object. For instance, the option:

cursor {string}, defines the mouse-cursor for individual cell
is associated with the property:
Cursor {string}, defines the mouse-cursor for individual cell
which means that the following statements are equivalent:
oCell.Options = {cursor: "pointer"}
oCell.SetOptions({cursor: "pointer"})
oCell.Cursor = "pointer"
oCell.SetCursor("pointer")
where oCell is an object of Cell type
Parameters:
Name Type Description
oItem Item Indicates the owner item of the cell as an object of Item type
oColumn Column Indicates the owner column of the cell as an object of Column type

Methods

Edit(editOptsopt)

The Edit() method edits the current cell.
Parameters:
Name Type Attributes Description
editOpts object <optional>
 Indicates an object of EditOptions type that holds options to show the cell's editor.
Properties
Name Type Description
change boolean specifies whether the cell's value is updated as soon as user types into the <input> element. If the change field is missing/null/undefined/0 the cell's value is updated as soon as user clicks outside of the cell, or presses Enter key
selectAll boolean selects all the text into the <input> element, as soon as the cell gets edited
ttc number indicates the time in ms to wait until cell's value is changed once the user alters the text within the <input> element (should be used when change field is specified)
inner EditInnerType specifies an object whose properties (recursively) are applied to the inner HTML-element

Example:

style: { border: "2px solid rgba(64,128,255,0.25)", padding: "2px" }, shows a blue border arroud the <input> element
view TV specifies the view where the <input> element should be displayed. The view field has no effect, if the control displays a single view. Use the AddTreeView() method to add a new view to the control. You can use the onclick event's "view" field to specify the view where the edit is displayed.
thisArg any indicates the value of "this" keyword during the validate callback (if not specified the thisArg refers to the current cell as an object of Cell type)
callback any a function of callback(value) {boolean} type that validates the newly value. The new value is validated if the function returns true, else the value is not validated and so no change occurs within the cell's value

Example:

validate: function(value) { return value < 10; }, validates only values less than 10 (in other words the cell's value is changed only if the value is less than 10)
validate: function(value) { return this.SetValue(Math.min(10, value)) || true; }, validates any value, but always ensures that's not greater than 10

Evaluate(formula) → {any}

The Evaluate() method evaluates the formula and returns the result
Parameters:
Name Type Description
formula string Indicates the format to evaluate the cell (uses cell/column's format in case it missing) The format-expression supports the following keywords:
value, indicates the value of the current cell ( "value/2 format ``", displays half of the value using current regional format )
%0, %1, %2, ... specifies the value of the cell in the column with the index 0, 1 2, ... ( "currency(%0 + %1)", adds the value of first and second cell and displays it as a currency )
%C0, %C1, %C2, ... specifies the caption of the cell, or the string the cell displays in the column with the index 0, 1 2, ... ( "%C0 + %C1", concatenates the caption of first and second cell )
%CD0, %CD1, %CD2, ... specifies the cell's user-date in the column with the index 0, 1 2, ... ( "%CD0 ? value : ``", displays the cell's value only if the cell's data is not empty )
%CS0, %CS1, %CS2, ... specifies the cell's state in the column with the index 0, 1 2, ... ( "(%CS0 ? `<b>` : ``) + value", displays the cell's value in bold only if the first cell is checked )
The format-expression supports the following unary-operators:
  • exp(``), checks whether the item is expanded or collapsed ( "(exp(``) ? `<b>` : ``) + value", shows expanded-items in bold )
  • get(`aggregate(list,direction,formula)`), summarizes the cell based on "aggregate(list,direction,formula)" syntax, where:
    aggregate, must be one of the following:
    • sum, performs addition of values
    • min, retrieves the minimum value
    • max, retrieves the maximum value
    • count, counts the number of items

    • current, refers the current item
    • parent, refers to the parent item
    • root, refers to the root item (the root item has no parent items)
    direction, must be one of the following:

    • all, collects all descendents
    Currently, the following items are excluded by aggregate functions:
    not-sortable items. The SortableItem property specifies whether the item can be sorted ( a sortable item can change its position after sorting, while a not-sortable item keeps its position after sorting. not-selectable items. The SelectableItem property specifies whether the user can selects/focus the specified item. divider items. The ItemDivider property specifies whether the item displays a single cell, instead displaying whole cells.

    "get(`sum(current,dir,%1 ? 1 : 0)`)", counts the number of child-items that have not-empty cells within the second-column
    "get(`sum(current,dir,value)`)", gets the total of values of child-items (direct descendent) within the same column
    "get(`sum(all,rec,value)`)", gets the total of values of leaf-items within the same column
    "get(`sum(parent,dir,dbl(%1) + dbl(%2))`)", gets the addition of all cells in the second (%1) and third (%2) column that are directly descendent of the parent item (sibling)
The format-expression supports the following binary-operators:
0 index `format`, gets the index of the item (0-based). The first added item has the index 0, the second added item has the index 1, and so on. The index of the item remains the same even if the order of the items is changed by sorting or grouping ( "1 index ``", gets the index of the item starting from 1 )
0 rindex `delimiter|format|format|...`, returns the recursive-index of the item ("1 rindex `.|A-Z`", returns values as A, A.1, A.2, B, ...)

SetFormatText(value)

The SetFormatText() method changes the format to display the cell's value.
Parameters:
Name Type Description
value exontrol.DrawTextFormatEnum Specifies a value of exontrol.DrawTextFormatEnum value that defines the format to show the cell's value. The exontrol.DrawTextFormatEnum type supports the following flags:
  • exTextAlignTop (0x00), justifies the text to the top of the rectangle
  • exTextAlignLeft (0x00), aligns text to the left
  • exTextAlignCenter (0x01), centers text horizontally in the rectangle
  • exTextAlignRight (0x02), aligns text to the right
  • exTextAlignVCenter (0x04), centers text vertically
  • exTextAlignBottom (0x08), justifies the text to the bottom of the rectangle.
  • exTextAlignMask (0x0F), specifies the mask for text's alignment.
  • exTextWordBreak (0x10), breaks words. Lines are automatically broken between words if a word would extend past the edge of the rectangle specified by the lpRect parameter. A carriage return-line feed sequence also breaks the line. If this is not specified, output is on one line.
  • exTextSingleLine (0x20), displays text on a single line only. Carriage returns and line feeds do not break the line.
  • exTextExpandTabs (0x40), expands tab characters. The default number of characters per tab is eight.
  • exPlainText (0x80), treats the text as plain text.
  • exTextNoClip (0x0100), draws without clipping.
  • exHTMLTextNoColors (0x0200), ignores the and tags.
  • exTextCalcRect (0x0400), determines the width and height of the text.
  • exHTMLTextNoTags (0x0800), ignores all HTML tags.
  • exTextPathEllipsis (0x4000), for displayed text, replaces characters in the middle of the string with ellipses so that the result fits in the specified rectangle. If the string contains backslash (\) characters, exTextPathEllipsis preserves as much as possible of the text after the last backslash.
  • exTextEndEllipsis (0x8000), for displayed text, if the end of a string does not fit in the rectangle, it is truncated and ellipses are added. If a word that is not at the end of the string goes beyond the limits of the rectangle, it is truncated without ellipses.
  • exTextWordEllipsis (0x040000), truncates any word that does not fit in the rectangle and adds ellipses.
Example
null {null}, centers the caption
  32 or exontrol.DrawTextFormatEnum.exTextSingleLine {number}, defines a single-line caption
  0x2A or exontrol.DrawTextFormatEnum.exTextSingleLine | exontrol.DrawTextFormatEnum.exTextAlignRight | exontrol.DrawTextFormatEnum.exTextAlignBottom {number}, defines a single-line caption right/bottom-aligned
