Web Components Grid Column Hiding

    The Ignite UI for Web Components has a built-in column hiding UI, which can be used through the Web Components Grid toolbar to change the visible state of the columns. Developers have the flexibility to define the Column Hiding UI anywhere within the page as needed. The Web Components Grid Column Hiding feature is especially useful when one wants to decrease the size of the grid and to eliminate the need for tabbing through redundant fields.

    Web Components Grid Column Hiding Example

    Grid Setup

    Let's start by creating our IgcGridComponent and binding it to our data. We will also enable both filtering and sorting for the columns.

    <igc-grid id="grid" auto-generate="false" width="100%" height="560px" allow-filtering="true">
    <igc-column field="ID" data-type="String" sortable="true" hidden="true"></igc-column>
    <igc-column field="ContactName" data-type="String" sortable="true" hidden="true"></igc-column>
    <igc-column field="ContactTitle" data-type="String" sortable="true"></igc-column>
    <igc-column field="City" data-type="String" sortable="true"></igc-column>
    <igc-column field="CompanyName" data-type="String" sortable="true"></igc-column>
    <igc-column field="Fax" data-type="String" sortable="true"></igc-column>
    <igc-column field="Address" data-type="String" sortable="true"></igc-column>
    <igc-column field="PostalCode" data-type="String" sortable="true"></igc-column>
    <igc-column field="Country" data-type="String" sortable="true"></igc-column>
    <igc-column field="Phone" data-type="String" sortable="true"></igc-column>
</igc-grid>

    Toolbar's Column Hiding UI

    The built-in Column Hiding UI is placed inside an DropDown in the IgcGridComponent's toolbar. We can show/hide the Column Hiding UI by using this exact dropdown.

    For this purpose all we have to do is set both the IgcGridToolbarActions and the IgcGridToolbarHiding inside of the IgcGridComponent. We will also add a title to our toolbar by using the IgcGridToolbarTitle and a custom style for our Grid's wrapper.

    <igc-grid>
    <igc-grid-toolbar>
        <igc-grid-toolbar-actions>
            <igc-grid-toolbar-hiding></igc-grid-toolbar-hiding>
        </igc-grid-toolbar-actions>
    </igc-grid-toolbar>
</igc-grid>

    The IgcGridComponent provides us with some useful properties when it comes to using the toolbar's column hiding UI.

    By using the title property, we will set the title that is displayed inside the dropdown button in the toolbar.

    <igc-grid id="grid">
    <igc-grid-toolbar>
        <igc-grid-toolbar-actions>
            <igc-grid-toolbar-hiding id="hidingAction" title="Column Hiding"></igc-grid-toolbar-hiding>
        </igc-grid-toolbar-actions>
    </igc-grid-toolbar>
</igc-grid>

    You can see the result of the code from above at the beginning of this article in the Web Components Column Hiding Example section.

    Disable hiding of a column

    We can easily prevent the user from being able to hide columns through the column hiding UI by simply setting their disableHiding property to true.

    <igc-grid>
    <igc-column field="ContactName" data-type="String" sortable="true" disable-hiding="true"></igc-column>
    <igc-column field="ContactTitle" data-type="String" sortable="true" disable-hiding="true"></igc-column>
</igc-grid>

    Styling

    The grid could be further customized by setting some of the available CSS variables. In order to achieve that, we will use a class that we will first assign to the grid:

    <igc-grid class="grid"></igc-grid>

    Then set the related CSS variables for the related components. We will apply the styles also only on the igx-column-actions, so the rest of the grid is unaffected:

    .grid  igx-column-actions {
    /* Main Column Actions styles */
    --ig-column-actions-background-color: #292826;
    --ig-column-actions-title-color: #ffcd0f;

    /* Checkbox styles */
    --ig-checkbox-tick-color: #292826;
    --ig-checkbox-label-color: #ffcd0f;
    --ig-checkbox-empty-color: #ffcd0f;
    --ig-checkbox-fill-color: #ffcd0f;

    /* Input styles */
    --ig-input-group-idle-text-color: white;
    --ig-input-group-filled-text-color: #ffcd0f;
    --ig-input-group-focused-text-color: #ffcd0f;
    --ig-input-group-focused-border-color: #ffcd0f;
    --ig-input-group-focused-secondary-color: #ffcd0f;

    /* Buttons styles */
    --ig-button-foreground: #292826;
    --ig-button-background: #ffcd0f;
    --ig-button-hover-background: #404040;
    --ig-button-hover-foreground: #ffcd0f;
    --ig-button-focus-background: #ffcd0f;
    --ig-button-focus-foreground: black;
    --ig-button-focus-visible-background: #ffcd0f;
    --ig-button-focus-visible-foreground: black;
    --ig-button-disabled-foreground: #ffcd0f;
}
