Angular Pivot Grid Column Pinning

    A column or multiple columns can be pinned to the left or right side of the Angular UI Grid. Column Pinning in Ignite UI for Angular allows the end users to lock column in a particular column order, this will allow them to see it while horizontally scrolling the Pivot Grid. The Material UI Grid has a built-in column pinning UI, which can be used through the Pivot Grid's toolbar to change the pin state of the columns. In addition, you can define a custom UI and change the pin state of the columns via the Column Pinning API.

    Angular Pivot Grid Column Pinning Example

    Column Pinning API

    Column pinning is controlled through the pinned input of the igx-column. Pinned columns are rendered on the left side of the Pivot Grid by default and stay fixed through horizontal scrolling of the unpinned columns in the Pivot Grid body.

    You may also use the Pivot Grid's pinColumn or unpinColumn methods of the IgxPivotGridComponent to pin or unpin columns by their field name:

    Both methods return a boolean value indicating whether their respective operation is successful or not. Usually the reason they fail is that the column is already in the desired state.

    A column is pinned to the right of the rightmost pinned column. Changing the order of the pinned columns can be done by subscribing to the columnPin event and changing the insertAtIndex property of the event arguments to the desired position index.

    Pinning Position

    You can change the column pinning position via the pinning configuration option. It allows you to set the columns position to either Start or End. When set to End the columns are rendered at the end of the grid, after the unpinned columns. Unpinned columns can be scrolled horizontally, while the pinned columns remain fixed on the right.

    public pinningConfig: IPinningConfig = { columns: ColumnPinningPosition.End };

    Demo

    Custom Column Pinning UI

    You can define your custom UI and change the pin state of the columns via the related API.

    Let's say that instead of a toolbar you would like to define pin icons in the column headers that the end user can click to change the particular column's pin state. This can be done by creating a header template for the column with a custom icon.

    On click of the custom icon the pin state of the related column can be changed using the column's API methods.

    public toggleColumn(col: ColumnType) {
    col.pinned ? col.unpin() : col.pin();
}

    Demo

    Pinning Limitations

    • Setting column widths in percentage (%) explicitly makes the Pivot Grid body and header content to be misaligned when there are pinned columns. For column pinning to function correctly the column widths should be in pixels (px) or auto-assigned by the Pivot Grid.
