3/31/2024 0 Comments Ag grid column types![]() ![]() We use the same process for working with APIs, but we might have to customise the fetch a little more. In the previous example, we just process a simple JSON file from a GET request. The most important property is the name of the field to map to in the rowData.Į.g. The Column Definitions array contains ColDef objects with the properties defined in the documentation for Column Def Properties. Set the definitions to use the amended array by using the API call ('columnDefs', colDefs). ![]() Amend the Array of Column Definitions to use the keys.Get the Column Definitions from the grid using the API call getColumnDefs().The short answer to "How to set the column definitions from JSON" is: If we dynamically set the data from a JSON file then we can't offer as rich a user experience as we don't really know what data will be present and the only information we have for the columns is their name. The normal use case for AG Grid is to render a specific set of data in a controlled way, this allows pre-configuration of the formatting, editing, header names etc. The information required to handle this is contained in our documentation for Updating Column Definitions. Example of Setting Column Definitions Dynamically From JSON.We will read JSON information from an API and use the keys from the returned JSON objects to configure the column heading names while rendering returned data in the grid. In this blog post we will show how to dynamically configure and read a JSON object from API calls into AG Grid.
