wijmo.vue2.grid Module

The wj-flex-grid component may contain the following child components: wijmo.vue2.grid.detail.WjFlexGridDetail , wijmo.vue2.grid.filter.WjFlexGridFilter , wijmo.vue2.grid.WjFlexGridColumn , wijmo.vue2.grid.WjFlexGridColumnGroup and wijmo.vue2.grid.WjFlexGridCellTemplate.

The component supports all properties and events of the pure JavaScript wijmo.grid.FlexGrid control it represents.

The component includes an initialized event that is raised when the control is initialized after it is added to the page. You can use this event to perform further initialization in addition to setting properties in markup. The signature of the handler function is the same as any other Wijmo event handlers.

The example below shows how to instantiate and initialize a wijmo.grid.FlexGrid control using Vue markup:

<wj-flex-grid
  :items-source="data">
  <wj-flex-grid-column binding="name" header="Name">
  </wj-flex-grid-column>
  <wj-flex-grid-column binding="sales" header="Sales" format="c0">
  </wj-flex-grid-column>
  <wj-flex-grid-column binding="expenses" header="Expenses" format="c0">
  </wj-flex-grid-column>
  <wj-flex-grid-column binding="active" header="Active">
  </wj-flex-grid-column>
  <wj-flex-grid-column binding="date" header="Date">
  </wj-flex-grid-column>
</wj-flex-grid>

The code sets the itemsSource property to a collection that contains the grid data, then specifies the columns to display using wj-flex-grid-column components.

The wj-flex-grid-cell-template component defines a template for a certain cell type in FlexGrid. The template element must contain a cellType attribute that specifies the {@link wijmo.vue2.grid.CellTemplateType}. Depending on the template's cell type, the wj-flex-grid-cell-template element must be a child of either wijmo.vue2.grid.WjFlexGrid or wijmo.vue2.grid.WjFlexGridColumn components.

Column-specific cell templates must be contained in wj-flex-grid-column components, and cells that are not column-specific (like row header or top left cells) must be contained in the wj-flex-grid component.

The wj-flex-grid-cell-template element may contain an arbitrary HTML fragment with Vue interpolation expressions and other components and directives.

Bindings in HTML fragment can use scoped slot properties that store cell specific data. The properties are col, row, and item, which refer to the Column, Row, and Row.dataItem objects pertaining to the cell.

For cell types like Group and CellEdit, an additional value property containing an unformatted cell value is provided.

To reference slot properties, you can use either a new v-slot directive right on the wj-flex-grid-cell-template element (it's available in Vue 2.6.0 or higher), or an old slot-scope directive on the <template> element nested in wj-flex-grid-cell-template.

For example, here is a FlexGrid control with templates for row header cells and, regular and column header cells of the Country column:

<!-- component.html -->
<wj-flex-grid :itemsSource="data">
  <wj-flex-grid-cell-template cellType="RowHeader" v-slot="cell">
    {{cell.row.index}}
  </wj-flex-grid-cell-template>
  <wj-flex-grid-cell-template cellType="RowHeaderEdit">
    ...
  </wj-flex-grid-cell-template>

  <wj-flex-grid-column header="Country" binding="country">
    <wj-flex-grid-cell-template cellType="ColumnHeader" v-slot="cell">
      <img src="resources/globe.png" />
        {{cell.col.header}}
    </wj-flex-grid-cell-template>
    <wj-flex-grid-cell-template cellType="Cell" v-slot="cell">
      <img :src="'resources/' + cell.item.country + '.png'" />
      {{cell.item.country}}
    </wj-flex-grid-cell-template>
  </wj-flex-grid-column>
  <wj-flex-grid-column header="Sales" binding="sales"></wj-flex-grid-column>
</wj-flex-grid>

The wj-flex-grid-cell-template directive supports the following attributes:

cellType

The CellTemplateType value defining the type of cell to which the template is applied.

autoSizeRows

Indicates whether the cell template will increase grid's default row height to accomodate cells content. Defaults to true.

cellOverflow

Defines the style.overflow property value for cells.

forceFullEdit

For cell edit templates, indicates whether cell editing forcibly starts in full edit mode, regardless of how the editing was initiated. In full edit mode pressing cursor keys don't finish editing. Defaults to true.

The cellType attribute takes any of the following enumerated values:

Cell

Defines a regular (data) cell template. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component. For example, this cell template shows flags in the cells of Country column:

<wj-flex-grid-column header="Country" binding="country">
  <wj-flex-grid-cell-template cellType="Cell" v-slot="cell">
    <img :src="'resources/' + cell.item.country + '.png'" />
    {{cell.item.country}}
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

If Group template is not provided for a hierarchical FlexGrid (that is, one with the childItemsPath property specified), non-header cells in group rows of this Column also use this template.

CellEdit

Defines a template for a cell in edit mode. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component. This cell type has an additional value scoped slot property available for binding. It contains the original cell value before editing, and the updated value after editing.

For example, here is a template that uses the Wijmo InputNumber control as an editor for the "Sales" column:

<wj-flex-grid-column header="Sales" binding="sales">
  <wj-flex-grid-cell-template cellType="CellEdit">
    <wj-input-number v-model="cell.value" :step="1"></wj-input-number>
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

Note that two-way binding can also be specified using the binding's sync modifier:

<wj-flex-grid-column header="Sales" binding="sales">
  <wj-flex-grid-cell-template cellType="CellEdit">
    <wj-input-number value.sync="cell.value" :step="1"></wj-input-number>
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

ColumnHeader

Defines a template for a column header cell. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component. For example, this template adds an image to the header of the "Country" column:

<wj-flex-grid-column header="Country" binding="country">
  <wj-flex-grid-cell-template cellType="ColumnHeader" v-slot="cell">
    <img src="resources/globe.png" />
    {{cell.col.header}}
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

RowHeader

Defines a template for a row header cell. Must be a child of the wijmo.vue2.grid.WjFlexGrid component. For example, this template shows row indices in the row headers:

<wj-flex-grid :itemsSource="data">
  <wj-flex-grid-cell-template cellType="RowHeader" v-slot="cell">
    {{cell.row.index + 1}}
  </wj-flex-grid-cell-template>
</wj-flex-grid>

Note that this template is applied to a row header cell, even if it is in a row that is in edit mode. In order to provide an edit-mode version of a row header cell with alternate content, define the RowHeaderEdit template.

RowHeaderEdit

Defines a template for a row header cell in edit mode. Must be a child of the wijmo.vue2.grid.WjFlexGrid component. For example, this template shows dots in the header of rows being edited:

<wj-flex-grid :itemsSource="data">
  <wj-flex-grid-cell-template cellType="RowHeaderEdit">
    ...
  </wj-flex-grid-cell-template>
</wj-flex-grid>

Use the following RowHeaderEdit template to add the standard edit-mode indicator to cells where the RowHeader template applies:

<wj-flex-grid :itemsSource="data">
  <wj-flex-grid-cell-template cellType="RowHeaderEdit">
    &#x270e;&#xfe0e;
  </wj-flex-grid-cell-template>
</wj-flex-grid>

TopLeft

Defines a template for the top left cell. Must be a child of the wijmo.vue2.grid.WjFlexGrid component. For example, this template shows a down/right glyph in the top-left cell of the grid:

<wj-flex-grid :itemsSource="data">
  <wj-flex-grid-cell-template cellType="TopLeft">
    <span class="wj-glyph-down-right"></span>
  </wj-flex-grid-cell-template>
</wj-flex-grid>

GroupHeader

Defines a template for a group header cell in a GroupRow. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component.

The row scoped slot property contains an instance of the GroupRow class. If the grouping comes from CollectionView, the item scoped slot property references the CollectionViewGroup object.

For example, this template uses a checkbox element as an expand/collapse toggle:

<wj-flex-grid-column header="Country" binding="country">
  <wj-flex-grid-cell-template cellType="GroupHeader" v-slot="cell">
    <input type="checkbox" v-model="cell.row.isCollapsed"/>
    {{cell.item.name}} ({{cell.item.items.length}} items)
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

Group

Defines a template for a regular cell (not a group header) in a GroupRow. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component. This cell type has an additional value scoped slot property available for binding. In cases where columns have the aggregate property specified, it contains the unformatted aggregate value.

For example, this template shows aggregate's value and kind for group row cells in the "Sales" column:

<wj-flex-grid-column header="Sales" binding="sales" aggregate="Avg">
  <wj-flex-grid-cell-template cellType="Group" v-slot="cell">
    Average: {{formatNumber(cell.value, 'N0')}}
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

ColumnFooter

Defines a template for a regular cell in a columnFooters panel. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component. This cell type has an additional value scoped slot property available for binding that contains a cell value.

For example, this template shows aggregate's value and kind for a footer cell in the "Sales" column:

<wj-flex-grid-column header="Sales" binding="sales" aggregate="Avg">
  <wj-flex-grid-cell-template cellType="ColumnFooter" v-slot="cell">
    Average: {{formatNumber(cell.value, 'N0')}}
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

BottomLeft

Defines a template for the bottom left cells (at the intersection of the row header and column footer cells). Must be a child of the wijmo.vue2.grid.WjFlexGrid component. For example, this template shows a sigma glyph in the bottom-left cell of the grid:

<wj-flex-grid :itemsSource="data">
  <wj-flex-grid-cell-template cellType="BottomLeft">
    &#931;
  </wj-flex-grid-cell-template>
</wj-flex-grid>

NewCellTemplate

Defines a cell in a new row template. Must be a child of the wijmo.vue2.grid.WjFlexGridColumn component. Note that the cell.item property is undefined for this type of a cell. For example, this cell template shows a placeholder in the Date column's cell in the "new row" item:

<wj-flex-grid-column header="'Date'" binding="'date'">
  <wj-flex-grid-cell-template cellType="NewCellTemplate">
    Enter a date here
  </wj-flex-grid-cell-template>
</wj-flex-grid-column>

The wj-flex-grid-column component should be contained in a wijmo.vue2.grid.WjFlexGrid component.

The wj-flex-grid-column component may contain a wijmo.vue2.grid.WjFlexGridCellTemplate child component.

The component supports all properties and events of the pure JavaScript wijmo.grid.Column class it represents.

The component includes an initialized event that is raised when the control is initialized after it is added to the page. You can use this event to perform further initialization in addition to setting properties in markup. The signature of the handler function is the same as any other Wijmo event handlers.

The wj-flex-grid-column-group component should be contained in one of the following components: wijmo.vue2.grid.WjFlexGrid or wijmo.vue2.grid.WjFlexGridColumnGroup.

The wj-flex-grid-column-group component may contain the following child components: wijmo.vue2.grid.WjFlexGridColumnGroup and wijmo.vue2.grid.WjFlexGridCellTemplate.

The component supports all properties and events of the pure JavaScript wijmo.grid.ColumnGroup class it represents.

The component includes an initialized event that is raised when the control is initialized after it is added to the page. You can use this event to perform further initialization in addition to setting properties in markup. The signature of the handler function is the same as any other Wijmo event handlers.
