ui.igTreeGrid
The igTreeGrid™ presents hierarchical data by combining the principles of a tree and tabular data into a single control. Inside the igTreeGrid hierarchical data is rendered using the same columns for each row while providing a way for users to expand and collapse child data.
As the igTreeGrid inherits the igGrid control, it is able to enjoy many of the same features and functionality as the igGrid. Some features differ in function and implementation to best suit the needs of hierarchical data (e.g. filtering, paging, etc.).
In order to maintain flexibility the tree grid features a configurable expansion indicator, which can be rendered inline in the first data column or in a standalone column. The expansion indicator can also be customized with a different look-and-feel to achieve custom visualizations (see the File Explorer sample).
Note: The igTreeGrid is a stand-alone control, which also uses all of the options, events and methods of the igGrid.
The following code snippet demonstrates how to initialize the igTreeGrid control.

Inherits
-
adjustVirtualHeights
Inherited- Type:
- bool
- Default:
- false
If this option is set to true, the height of the grid row will be calculated automatically based on the avgRowHeight and the visible virtual records. If no avgRowHeight is specified, it will be calculated automatically at runtime.
Code Sample
// Initialize $(".selector").igTreeGrid({ adjustVirtualHeights : true }); // Get var virtualHeights = $(".selector").igTreeGrid("option", "adjustVirtualHeights");
-
aggregateTransactions
Inherited- Type:
- bool
- Default:
- false
If set to true, the following behavior will take place:
If a new row is added, and then deleted, there will be no transaction added to the log.
If a new row is added, edited, then deleted, there will be no transaction added to the log.
If several edits are made to a row or an individual cell, this should result in a single transaction.
Note: This option takes effect only when autoCommit is set to false.Code Sample
//Initialize $(".selector").igTreeGrid({ aggregateTransactions : true }); //Get var aggregateTransactions = $(".selector").igTreeGrid("option", "aggregateTransactions");
-
alternateRowStyles
Inherited- Type:
- bool
- Default:
- true
Enables/disables rendering of alternating row styles (odd and even rows receive different styling).
Code Sample
//Initialize $(".selector").igTreeGrid({ alternateRowStyles : true; }); //Get var rowAltStyles = $(".selector").igTreeGrid("option", "alternateRowStyles"); //Set $(".selector").igTreeGrid("option", "alternateRowStyles", true);
-
autoAdjustHeight
Inherited- Type:
- bool
- Default:
- true
If autoAdjustHeight is set to false, the height will be set only on the scrolling container, and all other UI elements such as paging footer / filter row / headers will add on top of that, so the total height of the grid will be more than this value - the height of the scroll container (content area) will not be dynamically calculated. Setting this option to false will usually result in a lot better initial rendering performance for large data sets ( > 1000 rows rendered at once, no virtualization enabled), since no reflows will be made by browsers when accessing DOM properties such as offsetHeight.
Code Sample
// Initialize $(".selector").igTreeGrid({ autoAdjustHeight : false }); // Get var adjustHeight = $(".selector").igTreeGrid("option", "autoAdjustHeight");
-
autoCommit
Inherited- Type:
- bool
- Default:
- false
Automatically commits the transactions as rows/cells are being edited to the client data source. A saveChanges call still needs to be performed in order to commit the transactions to a server-side data source.
Code Sample
//Initialize $(".selector").igTreeGrid({ autoCommit : true }); //Get var commit = $(".selector").igTreeGrid("option", "autoCommit");
-
autofitLastColumn
Inherited- Type:
- bool
- Default:
- true
If set to true and all columns' widths are specified and their combined width is less than the grid width then the last column width will be automatically adjusted to fill the remaining empty space of the grid.
Code Sample
//Initialize $(".selector").igTreeGrid({ autofitLastColumn : true }); //Get var autoFit = $(".selector").igTreeGrid("option", "autofitLastColumn");
-
autoFormat
Inherited- Type:
- enumeration
- Default:

- formats only Date columns.
- number
- Type:string
- formats only number columns.
- dateandnumber

- false
- Type:bool
- auto formatting is disabled.
Code Sample
//Initialize $(".selector").igTreeGrid({ autoFormat : "number" }); //Get var autoFormat = $(".selector").igTreeGrid("option", "autoFormat");
-
autoGenerateColumns
Inherited- Type:
- bool
- Default:
- true
If no columns collection is defined, and autoGenerateColumns is set to true, columns will be inferred from the data source before the dataRendering event is fired. The inferred columns collection will be available to the developer for modification at dataRendering. If autoGenerateColumns is not explicitly set and columns has at least one column defined then autoGenerateColumns is automatically set to false.
If autoGenerateColumns is true and there are columns defined auto-generated columns will render after the explicitly defined ones.
Since auto-generated columns don't have width defined consider setting defaultColumnWidth as well.Code Sample
// Initialize $(".selector").igTreeGrid({ autoGenerateColumns : false }); // Get var autoCols = $(".selector").igTreeGrid("option", "autoGenerateColumns");

If dataType is "number", then supported numeric formats are following: "number", "currency", "percent", "int", "double", "0.00", "#.0####", "0", "#.#######", etc.
The value of "double" will be similar to "number", but with unlimited maximum number of decimal places.
The format patterns and rules for numbers and dates are defined in $.ig.regional.defaults object.
If dataType is "string" or not set, then format is rendered as it is with replacement of possible "{0}" flag by value in cell. Example, if format is set to "Name: {0}" and value in cell is "Bob", then value will appear as "Name: Bob"
If value is set to "checkbox", then checkboxes are used regardless of renderCheckboxes option of the grid. That has effect only when dataType option of column is set to "bool".Code Sample
