Columns in Angular Grid component
04 Aug 2021 / 34 minutes to read
The column definitions are used as the dataSource schema in the Grid.
This plays a vital role in rendering column values in the required format.
The grid operations such as sorting, filtering and grouping etc. are performed based on column definitions.
The field property of the columns
is necessary to map the data source values in Grid columns.
Auto generation
The columns are automatically generated when
columns
declaration is empty or undefined while initializing the grid. All the columns in the dataSource are bound as grid columns.

typewill be determined from the first record of thedataSource.
Set Primary key column for auto generated columns when editing is enabled
Primary key can be defined in the declaration of column object of the grid. When we didn’t declare the columns, the grid will generate the columns automatically. For these auto generated columns, you can set isPrimaryKey column property as true by using the following ways,
If Primary key “column index” is known then refer the following code example

}Foreign Key Column
Foreign key column can be enabled by using column.dataSource,
column.foreignKeyField and
column.foreignKeyValue properties.
column.dataSource- Defines the foreign data.column.foreignKeyField- Defines the mapping column name to the foreign data.column.foreignKeyValue- Defines the display field from the foreign data.
In the following example, Employee Name is a foreign column which shows FirstName column from foreign data.
To use ForeignKeyColumn, you need to inject ForeignKeyService in the provider section of AppModule.

- For remote data, the sorting and grouping is done based on
column.foreignKeyFieldinstead ofcolumn.foreignKeyValue.- If
column.foreignKeyFieldis not defined, then the column usescolumn.field.
Header Template
You can customize the header element by using the headerTemplate property. In this demo, the custom element is rendered for both CustomerID and OrderDate column headers.

Number formatting
The number or integer values can be formatted using the below format strings.
| Format | Description | Remarks |
|---|---|---|
| N | Denotes numeric type. | The numeric format is followed by integer value as N2, N3. etc which denotes the number of precision to be allowed. |
| C | Denotes currency type. | The currency format is followed by integer value as C2, C3. etc which denotes the number of precision to be allowed. |
| P | Denotes percentage type | The percentage format expects the input value to be in the range of 0 to 1. For example the cell value 0.2 is formatted as 20%. The percentage format is followed by integer value as P2, P3. etc which denotes the number of precision to be allowed. |
Please refer to the link to know more about number format.
Date formatting
You can format date values either using built-in date format string or custom format string.
For built-in date format you can specify columns.format as string (Example: yMd). Please refer to the link to know more about Date formatting
You can also use custom format string to format the date values. Some of the custom formats and the formatted date values are given in the below table.
| Format | Formatted value |
|---|---|
| { type:‘date’, format:‘dd/MM/yyyy’ } | 04/07/1996 |
| { type:‘date’, format:‘dd.MM.yyyy’ } | 04.07.1996 |
| { type:‘date’, skeleton:‘short’ } | 7/4/96 |
| { type: ‘dateTime’, format: ‘dd/MM/yyyy hh:mm a’ } | 04/07/1996 12:00 AM |
| { type: ‘dateTime’, format: ‘MM/dd/yyyy hh:mm:ss a’ } | 07/04/1996 12:00:00 AM |

Reordering can be done by drag and drop of a particular column header from one index to another index within the grid.
To enable reordering, set the allowReordering to true.

To use the column resize, inject ResizeService in the provider section of AppModule.

platformBrowserDynamic().bootstrapModule(AppModule);You can disable Resizing for a particular column, by specifying
columns.allowResizingto false. In RTL mode, you can click and drag the left edge of header cell to resize the column.
Min and Max width
Columns can be restricted to resize in between minimum and maximum width by defining the
columns.minWidth and columns.maxWidth.
In the below sample, OrderID, Ship Name and Ship Country columns are defined with minimum and maximum width.

Stacked columns can be resized by clicking and dragging the right edge of the stacked column header. While dragging, the width of the respective child columns will be resized at the same time. You can disable resize for any particular stacked column by setting allowResizing as false to its columns.
In this example, we have disabled resize for Ship City column.

When you tap at the right edge of header cell, a floating handler will be visible over the right border of the column. To resize the column, tap and drag the floating handler as much you need. You can also autoFit a column by using the Column menu of the grid.
The following screenshot represents the column resizing on the touch device.
Resizing Events
During the resizing action, the grid component triggers the below three events.
- The
resizeStartevent triggers when column resize starts. - The
resizingevent triggers when column header element is dragged (moved) continuously.. - The
resizeStopevent triggers when column resize ends.

Column type can be specified using the columns.type property. It specifies the type of data the column binds.
If the format is defined for a column,
the column uses type to select the appropriate format option (number
or date).
Grid column supports the following types:
- string
- number
- boolean
- date
- datetime
If the
typeis not defined, then it will be determined from the first record of thedataSource. Incase if the first record of thedataSourceis null/blank value for a column then it is necessary to define thetypefor that column.
Column template
The column template has options to display custom element instead of a field value in the column.

The following sample, Filter item was hidden in column menu when opens for the OrderID column.

You can toggle column visibility based on media queries which are defined
at the hideAtMedia.
The hideAtMedia accepts valid
Media Queries. In the below sample, for OrderID column, hideAtMedia property value is set as (min-width: 700px) so that OrderID column will gets hidden when the browser screen width is lessthan 700px.
