Field List in JQuery PivotGrid widget
13 Feb 201912 minutes to read
Initialization
The field list, also known as Pivot Schema Designer, allows you to add, rearrange, filter, and remove fields to show the data in the pivot grid as exactly you want.
Based on the data source and OLAP bound to the pivot grid control, the PivotTable field list will be automatically populated with cube information or field names. The PivotTable field list provides an Excel like appearance and behavior.
To initialize the PivotTable field list, first you should define a “div” tag with an appropriate “id” attribute which acts as a container for the widget. Then, you should initialize the PivotTable field list by using the “ejPivotSchemaDesigner” method.

Layout
The top portion of the layout shows field or cube items in a categorized way. They can be dynamically added to the report either by the drag and drop option or through the simple check box selection.
On item(s) selection, they will be placed in the row section except numeric based item(s) or measures, which alone will be placed in the value section, by default.
The bottom portion of the layout is segregated as below:
- Report filter: Filter the item(s) placed in the particular position of the layout.
- Value section: The value label usually displays the numeric value item(s) present in the report.
- Column section: Displays the item(s) as column header and values in the pivot grid control.
- Row section: Display the item(s) as row header and values in the pivot grid control.

UI interactions
By drag and drop
You can alter the report on fly through the drag-and-drop operation. You can drag any item from the field list and drop it into column, row, value, or filter section available at the bottom of the field list.
NOTE
You can enable/disable the drag and drop operation by the
enableDragDropproperty.
By tree view selection
You can also alter the report on fly through the check and uncheck option as an alternate. By default, fields will be added to the row label when checked.
By context menu
You can also alter the report by using the context menu.
Searching values
Search option in the field list allows you to search a specific value that needs to be filtered from the list of values in the filter pop-up window.
Filtering
Values can be filtered by checking/unchecking the check box besides them, in the filter pop-up window. At least, one value should be present in the checked state while filtering. Otherwise “Ok” will be disabled.
Defer update
Defer update in the field list allows you to refresh the control on-demand and not during every UI operation. This operation can be enabled/disabled through the enableDeferUpdate property internally.
Showing KPI
The showKpi property is used to view the KPI elements in tree view in the pivot table field list. This property should be defined under the olap object.
<script type="text/javascript">
$("#PivotSchemaDesigner1").ejPivotSchemaDesigner({
olap: { showKpi : true }
});
</script>
Showing NamedSets
The showNamedSets property is used to view the named sets in tree view of the pivot table field list. This property should be defined under olap object.
<script type="text/javascript">
$("#PivotSchemaDesigner1").ejPivotSchemaDesigner({
olap: { showNamedSets : true }
});
</script>Setting pivot control to pivot schema designer
The pivotControl property is used to set the pivot control bound with the pivot schema designer.
<script type="text/javascript">
$("#PivotSchemaDesigner1").ejPivotSchemaDesigner({
pivotControl: controlObject
});
