![]() In this example, the requirement is to create a value getter that is type-safe and uses the data provided to AG Grid to conditionally multiply a value within our data set. This is where we can leverage the pipeline for rendering cells:Īnd, here is a demo using Angular: Using the valueGetter() callback functionįirst, we can use a valueGetter() to fetch and/or mutate data in a cell using a provided callback function. However, often times an AG Grid implementation is not this simple. Without any customization and in the simplest form, each cell in AG Grid is rendered as a string based on the field specified in the provided row data. How to create a type-safe and performant cell renderer There are two active row groups as the supplied country and year column definitions have rowGrouptrue declared.How to create a type-safe value formatted to format the value of a cell.The Group Column Filter will not work with the Group Rows display type as there are no group columns. Download v31 of the best React Data Grid in the world now. How to create a type-safe value getter to retrieve the value for a cell This section shows how the Group Column Filter can be used when row groups are displayed under group columns.How to leverage the new TypeScript generics provided by the AG Grid API (released in version 28).Many of our clients use AG Grid to meet customer requirements for displaying tabular data. Html.Here at LiveLoveApp, we're big fans of AG Grid - the best JavaScript grid in the world.įor two primary reasons: performance and extensibility. In this example, all columns are sortable, exceptįor the Name column, which has sortable set to False. Here’s a complete example using ColumnDefs and defaultColDef. In general, cell customization can be implemented using one of the following: cell templates with custom syntax for loops and conditionals. Then finally adds properties from the specific column definition. It then adds properties defined via column types (see the next section) and Starts with the default column definition. The following example shows how to appoint individual columns to show individual groups. The previous example makes all columns editable, except the Name column, because when the grid creates a column, it Adding to the previous example, here we configureĪll columns to be editable: columnsDefs = [Īnd here, we make all columns editable, except the Name column: columnsDefs = [ The following example shows a simple grid with 3 columns defined: Download v31 of the best React Data Grid in the world now. Col 5 and Col 6 have neither colId or field so the grid generates column IDs. The grid appends 1 to Col 4 to make the ID unique. Use defaultColDef to set properties that all columns will inherit. The grid appends 1 to Col 2 to make the ID unique. Here, we define a grid with 3 columns: columnsDefs = [ single will use single row selection, such that when you select a row, any previously selected row gets unselected. rowSelection: Type of row selection, set to either single or multiple to enable selection. Below shows the column definition properties for value formatters. putting in currency symbols and number formatting). numeric) but needs to be converted for human reading (e.g. This is useful when data is one type (e.g. Columnsįor a list of all properties that can be applied to a column. Selecting a row and holding down Shift while clicking a second row will select the range. Value formatters allow you to format values for display. Function: A function that returns JSX for display. Class: Direct reference to a cell renderer component. ![]() String: The name of a cell renderer component. undefined: Grid renders the value as a string. More details See: Row Grouping - Display Types. The cell renderer for a column is set via colDef.cellRenderer and can be any of the following types. custom: informs the grid that group columns will be provided. the ag-column-moving class is not added to the grid while columns are moving. If the rows supplied to the grid do not need to be grouped by the grid, consider using. An object map of custom column types which contain groups of properties that column definitions can reuse by referencing in their type property. The Display Types listed below are only concerned with how the results of Row Grouping are displayed in the grid. Define columns on the AgGrid component using the columnDefs property, provided as a list of dictionaries. Row Grouping performs a GROUP BY operation to the flat list of rows provided to the grid, where the rows are grouped by one or more columns.
