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.

 
				// Initialize
				$(".selector").igHierarchicalGrid({
					adjustVirtualHeights : true
				});

				// Get
				var virtualHeights = $(".selector").igHierarchicalGrid("option", "adjustVirtualHeights");
			 

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.

 
				//Initialize
				$(".selector").igHierarchicalGrid({
					aggregateTransactions : true
				});

				//Get
				var aggregateTransactions = $(".selector").igHierarchicalGrid("option", "aggregateTransactions");
			 

Enables/disables rendering of alternating row styles (odd and even rows receive different styling).

 
				//Initialize
				$(".selector").igHierarchicalGrid({
					alternateRowStyles : true;
				});

				//Get
				var rowAltStyles = $(".selector").igHierarchicalGrid("option", "alternateRowStyles");

				//Set
				$(".selector").igHierarchicalGrid("option", "alternateRowStyles", true);
			 

The row expanding/collapsing animation duration in ms.

  
        //Initialize
        $(".selector").igHierarchicalGrid({
            animationDuration: 1000
        });
        
        //Get
        var accessibility = $(".selector").igHierarchicalGrid("option", "animationDuration");
        
        //Set
        $(".selector").igHierarchicalGrid("option", "animationDuration", 1000);
        $(".selector").igHierarchicalGrid("dataBind");
        

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.

 
				// Initialize
				$(".selector").igHierarchicalGrid({
					autoAdjustHeight : false
				});

				// Get
				var adjustHeight = $(".selector").igHierarchicalGrid("option", "autoAdjustHeight");

				//Initialize
				$(".selector").igHierarchicalGrid({
					autoCommit : true
				});

				//Get
				var commit = $(".selector").igHierarchicalGrid("option", "autoCommit");
			 

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.

 
				//Initialize
				$(".selector").igHierarchicalGrid({
					autofitLastColumn : true
				});

				//Get
				var autoFit = $(".selector").igHierarchicalGrid("option", "autofitLastColumn");
			 

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.

 
				//Initialize
				$(".selector").igHierarchicalGrid({
					autoFormat : "number"
				});
				//Get
				var autoFormat = $(".selector").igHierarchicalGrid("option", "autoFormat");
			 

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.

 
				// Initialize
				$(".selector").igHierarchicalGrid({
					autoGenerateColumns : false
				});

				// Get
				var autoCols = $(".selector").igHierarchicalGrid("option", "autoGenerateColumns");

				});
				// Get
				var width = $(".selector").igHierarchicalGrid("option", "avgColumnWidth");

					avgRowHeight : "35px"
				});
				// Get
				var height = $(".selector").igHierarchicalGrid("option", "avgRowHeight");

• format

  Type:

  string

  Default:

  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 "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"
