tabOrder

tabOrder: number

Gets or sets a value of the tabindex attribute associated with the control.

tabindex attribute value can be defined statically for a Wijmo control by specifying it on the control's host HTML element. But this value can't be changed later during application lifecycle, because Wijmo controls have complex structure, and the control may need to propagate this attribute value to its internal element to work properly.

Because of this, to read or change control's tabindex dynamically, you should do it using this property.

tooltip

tooltip: ChartTooltip

Gets the chart Tooltip object.

The tooltip content is generated using a template that may contain any of the following parameters:

propertyName: Any property of the data object represented by the point.
seriesName: Name of the series that contains the data point (FlexChart only).
pointIndex: Index of the data point.
value: Value of the data point (y-value for FlexChart, item value for FlexPie).
x: x-value of the data point (FlexChart only).
y: y-value of the data point (FlexChart only).
name: Name of the data point (x-value for FlexChart or legend entry for FlexPie).

To modify the template, assign a new value to the tooltip's content property. For example:

chart.tooltip.content = '<b>{seriesName}</b> ' +
   '<img src="resources/{x}.png"/><br/>{y}';

You can disable chart tooltips by setting the template to an empty string.

You can also use the tooltip property to customize tooltip parameters such as Tooltip.showDelay and Tooltip.hideDelay:

chart.tooltip.showDelay = 1000;

See ChartTooltip properties for more details and options.

wjModelProperty

wjModelProperty: string

Methods

applyTemplate

applyTemplate(classNames: string, template: string, parts: Object, namePart?: string): HTMLElement

Inherited from Control.applyTemplate
Applies the template to a new instance of a control, and returns the root element.

This method should be called by constructors of templated controls. Therefore, this method is not available. It is responsible for binding the template parts to the corresponding control members.

For example, the code below applies a template to an instance of an InputNumber control. The template must contain elements with the 'wj-part' attribute set to 'input', 'btn-inc', and 'btn-dec'. The control members '_tbx', '_btnUp', and '_btnDn' will be assigned references to these elements.
```
this.applyTemplate('wj-control wj-inputnumber', templateString, {
  _tbx: 'input',
  _btnUp: 'btn-inc',
  _btnDn: 'btn-dec'
}, 'input');
```
@param classNames Names of classes to add to the control's host element. @param template An HTML string that defines the control template. @param parts A dictionary of part variables and their names. @param namePart Name of the part to be named after the host element. This determines how the control submits data when used in forms.
Parameters
- classNames: string
- template: string
- parts: Object
- Optional namePart: string
Returns HTMLElement

  Container element. If set to null, all Wijmo controls on the page will be invalidated.
Returns void

Static refreshAll

refreshAll(e?: HTMLElement): void

Inherited from Control.refreshAll

  Container element. If set to null, all Wijmo controls on the page will be invalidated.
Returns void

Events

gotFocus

gotFocus: Event<Control, EventArgs>

Occurs when the control gets the focus.

invalidInput

invalidInput: Event<Control, CancelEventArgs>

Occurs when invalid input is detected.

Invalid input may occur when the user types or pastes a value that cannot be converted to the proper type, or a value that is outside the valid range.

itemsSourceChanged: Event<FlexChartBase<any>, EventArgs>

Occurs after the chart has been bound to a new items source.

itemsSourceChanging

itemsSourceChanging: Event<FlexChartBase<any>, CancelEventArgs>

Occurs before the chart is bound to a new items source.

lostFocus

lostFocus: Event<Control, EventArgs>

Occurs when the control loses the focus.

refreshed

refreshed: Event<Control, EventArgs>

Occurs after the control has refreshed its contents.

refreshing

refreshing: Event<Control, EventArgs>

Occurs when the control is about to refresh its contents.

rendered
