Theming

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.

Related Samples

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:

date
Sets gets ability to automatically format text in cells for numeric and date columns. The format patterns and rules for numbers and dates are defined in $.ig.regional.defaults object. Here column formatting is explained in details.
Members
- date
- Type:string
- formats only Date columns.
- number
- Type:string
- formats only number columns.
- dateandnumber
- Type:string
- formats both Date and number columns.
- true
- Type:bool
- formats Date and number columns.
- 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");
			 
```

				//Set
				$(".selector").igTreeGrid("option", "caption", "Sales Data");

childDataKey

Type:: string
Default:: "childData"

Property name of the array of child data in a hierarchical data source.

Code Sample

 
				//Initialize
				$(".selector").igTreeGrid({
					childDataKey: "products"
				});

format

Type:

string

Default:

null
Gets/Sets the type of formatting for cells of the column. Default value is null. Checkout Formatting Dates, Numbers and Strings for details on the valid formatting specifiers.

If dataType is "date", then supported formats are following: "date", "dateLong", "dateTime", "time", "timeLong", "MM/dd/yyyy", "MMM-d, yy, h:mm:ss tt", "dddd d MMM", etc.
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".

					});
					//Get
					var colIndex = $(".selector").igTreeGrid("option", "columns")[1].navigationIndex;

rowIndex

Type:: number
Default:: null

Code Sample
```
 
				//Initialize
				$(".selector").igTreeGrid({
					serializeTransactionLog : false
				});

				//Get
				var log = $(".selector").igTreeGrid("option", "serializeTransactionLog");
			 
```

					tabIndex : 3
				});

				//Get
				var tabIndex = $(".selector").igTreeGrid("option", "tabIndex");

templatingEngine
Inherited

Type:

enumeration

Default:

infragistics
The templating engine that will be used to render the grid column templates. Here you can find how to use templating engines other than igTemplating and jsRender.
Members
- infragistics
- Type:string
- The grid will use the Infragistics Templating engine to render its column templates and specific parts of the UI.
- jsRender
- Type:string
- The grid will use jsRender to render its column templates and specific parts of the UI.
Code Sample
```
 
				// Initialize
				$(".selector").igTreeGrid({
					templatingEngine : "jsRender"
				});
				// Get
				var templatingEngine = $(".selector").igTreeGrid("option", "templatingEngine");

virtualization
Inherited

Type:

bool

Default:

false
Enables/disables column and row virtualization at the same time. Virtualization can greatly enhance rendering performance. If enabled, the number of actual rendered rows (DOM elements) will be constant and related to the visible viewport of the grid. As the end user scrolls, those DOM elements will be dynamically reused to render the new data. Here you can find more info about the performance guidelines when using the igGrid.
Code Sample
```
 
				// Initialize
				$(".selector").igTreeGrid({
					virtualization : true
				});

				// Get
				var virtualization = $(".selector").igTreeGrid("option", "virtualization");
			 
```
virtualizationMode

Type:

string

Default:

"continuous"
Determines row virtualization mode. For igTreeGrid only continuous virtualization can be used.

continuous renders a pre-defined number of rows in the grid. On scrolling the continuous virtualization loads another portion of rows and disposes the current one.
Code Sample
```
 
				// Initialize
				$(".selector").igTreeGrid({
					virtualizationMode : "continuous"
				});

				// Get
				var virtualizationMode = $(".selector").igTreeGrid("option", "virtualizationMode");

				// Set
				$(".selector").igTreeGrid("option", "virtualizationMode", "continuous");
			 
```

virtualizationMouseWheelStep
Inherited

Type:: number
Default:: null

Number of pixels to scroll the grid by, when virtualization is enabled, and mouse wheel scrolling is performed over the virtual grid area. If "null" the step will be equal to the avgRowHeight.

Code Sample

 
				// Initialize
				$(".selector").igTreeGrid({
					virtualizationMouseWheelStep : 50
				});

				// Get
				var virtualizationStep = $(".selector").igTreeGrid("option", "virtualizationMouseWheelStep");

				// Set
				$(".selector").igTreeGrid("option", "virtualizationMouseWheelStep", 50);

width
Inherited

Type:

enumeration

Default:

null
Defines the grid width in pixels or percents. Here you can find more info about setting igGrid width.

Code Sample
```
 
				// Initialize
				$(".selector").igTreeGrid({
					width : "800px"
				});
				// Get
				var width = $(".selector").igTreeGrid("option", "width");
				// Set
				$(".selector").igTreeGrid("option", "width", "850px");
