Ag grid dynamic columns8/18/2023 Col 5 and Col 6 have neither colId or field so the grid generates column IDs. 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.For instance, the column with field name will render the value stored in row.name. Lets go over these left to right, with each pair getting progressively more complex. Ag-Grid allows your users to easily manipulate data and immediately display any changes in it coming in from API or a server-side update. By default, the data grid uses the field of a column to get its value. In the default themes, this transpires to no animation for moving columns. The grid appends '_1' to Col 4 to make the ID unique. You’ll see three pairs of columns, each pair consists of one unformatted column and a duplicate column using a value formatter. If true, the ag-column-moving class is not added to the grid while columns are moving. Get the example code in Angular, React, Vue.JS and JavaScript. The grid appends '_1' to Col 2 to make the ID unique. See how to set ag-Grid column definitions dynamically based on the columns in your row data. Open the example in a new tab and observe the output in the dev console. In the example below, columns are set up to demonstrate the different ways IDs are generated. ![]() ![]() Finally, the ID is ensured to be unique by appending '_n' if necessary, where n is the first positive number that allows uniqueness.

Editing See Cell Editing for more information. Column Headers See Column Headers for more information. Remove duplicate columns columnDefinitions columnDefinitions.filter((column, index. If neither colId nor field exists then a number is assigned. Use our powerful mobile-first flexbox grid to build layouts of all shapes and sizes thanks to a twelve column system, six default responsive tiers. Column Definitions See Updating Column Definitions for more information. .If both colId and field exist then colId gets preference. If the user provides colId in the column definition, then this is used, otherwise the field is used. if two columns have the same field, or if you are using valueGetter instead of field) then it is useful to understand how column IDs are generated. If you are using the API and the column IDs are a little complex (e.g. The following example shows a simple grid with 3 columns defined: // define 3 columns const columnDefs = [ Column IDsĮach column generated by the grid is given a unique Column ID, which is used in parts of the Grid API.
