Sets the jqxTreeGrid's columns.

• text - string property which sets the column header's text.
• dataField - string property which sets the column's bound field. It should be unique and should point to a data field defined in the jqxDataAdapter's dataFields array.
• displayField - string property which sets the column's display field. It should be unique and should point to a data field defined in the jqxDataAdapter's dataFields array.
• sortable - boolean property which determines whether the column is sortable.
• filterable - boolean property which determines whether the column is filterable.
• hidden - boolean property which determines whether the column is visible or hidden.
• columnGroup - string property which determines the name of the column's parent group. It should point to a valid name defined in the columnGroups.
• autoCellHeight - boolean property which determines whether the cell's data wrapping is enabled. This property is set to true by default. When autoRowHeight is enabled and autoCellHeight is set to false, the cell's data will not be wrapped.
• renderer - callback function for custom rendering of the column's header.
• rendered - callback function which is called after the column's header rendering is completed.
• cellsRenderer - callback function which is called when a cell is being rendered. The result of that function should be valid and well-formatted HTML string. The cellsRenderer function has 4 parameters passed by jqxTreeGrid - row's key, column's data field, cell's value, row's data as an object of Key/Value pairs.
• columnType - string property which determines the column's type.
  Possible values:
  • "template" - sets a custom editor as a default editor for the column. The editor should be created in the createEditor callback function. The editor should be synchronized with the cell's value in the initEditor callback. The editor's value should be retrieved in the getEditorValue callback function.
  • "custom" - sets a custom editor as a default editor for a cell. That setting enables you to have different cell editors in the column. The editors should be created in the createEditor callback function which is called for each row when the columnType property is set to "custom". The editors should be synchronized with the cell's value in the initEditor callback. The editor's value should be retrieved in the getEditorValue callback function.
• validation - callback function which is called when the jqxTreeGrid's edited row needs to be validated. The function has 2 parameters - edit cell and the cell's value. The function should return true or false, depending on the user's validation logic. It can also return a validation object with 2 fields - "result" - true or false, and "message" - validation string displayed to the users.
• initEditor - callback function which is called when an editor is opened. It has 5 parameters - row's key, cell's value, the editor element, cell's width and cell's height. The function can be used for adding some custom parameters to the editor.
• createEditor - callback function which is called just once when the cells editor is created. It has 5 parameters - row's key, cell's value, the editor element, cell's width and cell's height. The function can be used for adding some custom parameters to the editor.
• getEditorValue - callback function which could be used for overriding the value returned by the editor. It is useful for advanced scenarios with custom editors. It has 3 parameters - row's key, cell's value and the editor element. The result of the function is expected to be the editor's new value.
• cellsFormat - determines the Format string used for formatting the cell values.
  
  Possible number strings:
  "d" - decimal numbers.
  "f" - floating-point numbers.
  "n" - integer numbers.
  "c" - currency numbers.
  "p" - percentage numbers.
  
  For adding decimal places to the numbers, add a number after the formatting string.
  For example: "c3" displays a number in this format $25.256
  Possible built-in Date formats:
  
  // short date pattern d: "M/d/yyyy",
  // long date pattern D: "dddd, MMMM dd, yyyy",
  // short time pattern t: "h:mm tt",
  // long time pattern T: "h:mm:ss tt",
  // long date, short time pattern f: "dddd, MMMM dd, yyyy h:mm tt",
  // long date, long time pattern F: "dddd, MMMM dd, yyyy h:mm:ss tt",
  // month/day pattern M: "MMMM dd",
  // month/year pattern Y: "yyyy MMMM",
  // S is a sortable format that does not vary by culture S: "yyyy\u0027-\u0027MM\u0027-\u0027dd\u0027T\u0027HH\u0027:\u0027mm\u0027:\u0027ss"
  
  Possible Date format strings:
  
  "d"-the day of the month;
  "dd"-the day of the month;
  "ddd"-the abbreviated name of the day of the week;
  "dddd"- the full name of the day of the week;
  "h"-the hour, using a 12-hour clock from 1 to 12;
  "hh"-the hour, using a 12-hour clock from 01 to 12;
  "H"-the hour, using a 24-hour clock from 0 to 23;
  "HH"- the hour, using a 24-hour clock from 00 to 23;
  "m"-the minute, from 0 through 59;
  "mm"-the minutes,from 00 though59;
  "M"- the month, from 1 through 12;
  "MM"- the month, from 01 through 12;
  "MMM"-the abbreviated name of the month;
  "MMMM"-the full name of the month;
  "s"-the second, from 0 through 59;
  "ss"-the second, from 00 through 59;
  "t"- the first character of the AM/PM designator;
  "tt"-the AM/PM designator;
  "y"- the year, from 0 to 99;
  "yy"- the year, from 00 to 99;
  "yyy"-the year, with a minimum of three digits;
  "yyyy"-the year as a four-digit number;
  
• aggregates - array property which determines the column aggregates.
  
  Aggregate functions:
  • 'avg' - Average aggregate
  • 'count' - Count aggregate
  • 'min' - Min aggregate
  • 'max' - Max aggregate
  • 'sum' - Sum aggregate
  • 'product' - Product aggregate
  • 'stdev' - Standard deviation on a sample.
  • 'stdevp' - Standard deviation on an entire population.
  • 'varp' - Variance on an entire population.
  • 'var' - Variance on a sample.
  
  Custom Aggregate
  

  
  aggregates: [{ 'In Stock':
      function (aggregatedValue, currentValue) {
          if (currentValue) {
              return aggregatedValue + 1;
          }
          return aggregatedValue;
      }
  }
  

  
  Custom Aggregate which aggregates values from two columns
  

  
  { text: 'Price', dataField: 'price', cellsAlign: 'right', cellsFormat: 'c2', aggregates: [{ 'Total':
              function (aggregatedValue, currentValue, column, record) {
                  var total = currentValue * parseInt(record['quantity']);
                  return aggregatedValue + total;
              }
          }]                  
   }
  

  
  'In Stock' - the aggregate's display name. The function has 2 params - the aggregated value and the current value. It should return an aggregated value.
• aggregatesRenderer - callback function which could be used for customization of the aggregates rendering. It has 1 parameter - the column's aggregates.
• align - string property which determines the alignment of the column's header. Possible values: 'left', 'center' or 'right'
• cellsAlign - string property which determines the alignment of the column's cells. Possible values: 'left', 'center' or 'right'.
• width - numeric property which determines the column's width.
• minWidth - numeric property which determines the column's minimum width. Default value: 25.
• maxWidth - numeric property which determines the column's maximum width.
• resizable - boolean property which determines whether the column is resizable.
• draggable - boolean property which determines whether the column is draggable.
• editable - boolean property which determines whether the column is editable.
• className - string property which sets a custom CSS class for the column's header
• cellClassName - string or function property which sets a custom CSS class for the column's cells. The value could be a "string" or "Function".
• pinned - boolean property which determines whether the column is pinned(frozen).

By defining that function you can load data into jqxTreeGrid dynamically. For each record only when required, jqxTreeGrid calls virtualModeCreateRecords function and this allows you to provide records on demand. In order to enable the load on demand feature, you should also define the virtualModeRecordCreating function.

• Row Key/ID - unique ID. If null is passed, that the function's result would be the records of the first hierarchy level.
• Done - callback function. Call it when data is loaded and pass the loaded data as an Array.

By defining that function you can initialize the dynamic data that you load into jqxTreeGrid. In order to enable the load on demand feature, you should also define virtualModeCreateRecords function.

• Row - object with the following reserved members:
  • checked - boolean value. Determines the row's checked state.
  • expanded - boolean value. Determines the row's expanded state.
  • icon - string value. Determines the row's icon url.
  • leaf - boolean value. Determines whether the row is a leaf in the hierarchy. When you set leaf to true, the expand/collapse button would not be displayed.
  • level - Integer value. Returns the row's hierarchy level.
  • selected - boolean value. Determines the row's selected state.

This event is triggered when the jqxTreeGrid binding is completed. *Bind to that event before the jqxTreeGrid's initialization. Otherwise, if you are populating the widget from a local data source and bind to bindingComplete after the initialization, the event could be already raised when you attach an event handler to it.

Code examples

Bind to the bindingComplete event of jqxTreeGrid.

This is triggered when a cell edit begins. Note: To turn on cell editing, you should set the editSettings property and make sure that its editSingleCell sub property is set to true.

Code examples

Bind to the cellBeginEdit event of jqxTreeGrid.

Adds a new row. For synchronization with a server, please look also the jqxDataAdapter plug-in's help documentation.

• Row Key/ID - unique ID which identifies the row. If null is passed, the jqxTreeGrid will generate an unique.
• Row Data - object with Key/Value pairs. To add an empty row, pass {}.
• Row Position - string with two possible values - "last" and "first". By default "last" is used.
