![]() ![]() As mentioned before, this is a simplified version, but the problem is the same. I would assume that it would sort the table in reverse order but nothing is happening instead, I just get the table as specified in rowData and as soon something is written into the filter field all entries are filtered. ![]() export interface VersionInfo ` Įverything is working fine excepet for the comparator. I have an interface VersionInfo which represent the object I am passing to the grid. Below I have a very simplified version of my problem. (for set filter).I have an ag-grid table and I am passing some objects as data. One such feature is Value Getter & Value Formatter. Core feature of ag-Grid supporting Angular, React, Javascript and more. But thats besides the point, valuegetter and valueformatter will just return the observable object as they are synchronous. So if you define valueFormatter forĪ column, do not expect formatted values to show up in column filters ag-Grid - Working with Data: Value Getter & Value Formatter. As of today, the column filters in ag-grid are driven offĬolDef.field or valueGetter. For instance, the column with field name will render the value stored in row.name. Version 17 is available for download now, take it for a free two month trial. Value getters are a method for customizing the formatting and display of data in the grid. By default, the data grid uses the field of a column to get its value. Keep input value after reloading/refreshing page. Use Value Formatters to format values for display. Refresh ag-Grid after a data change with React, Angular, Vue and JS. Use Value Getters when the data is not a simple field. Value Getters & Value Formatters are about getting and formatting the data to display. It is the inverse of ValueFormatter, it lets you format your data before you set the value for the cell.Īfter editing cells in the grid you have the opportunity to parse theĪ typical use case would be if your number is displayed with commas, you would want to parse it to remove commas when you edit it and setting data to your row. ag-Grid is a feature-rich data grid supporting major JavaScript Frameworks. Notice the following: The 'Total' column uses a value getter to calculate the sum of all values in that row. The grid is doing all the refresh by itself with no need for the client application explicitly requesting a refresh. Use value getters when retrieving the data requires more logic, including executing your own. A Value Getter is a function that gets called allowing values to be pulled from literally anywhere, including executing any expressions you wish along the way. The example below shows the impact of change detection on value getters. This video and the next three are based on the aggr-data starting point. Value parser should be used when editing cells. Example: Change Detection and Value Getters. This will not affect the underlying data.Ī classic use case is when you want to round numbers for a numeric field. Value formatter should be used when you want to format your data for display. Note that valueGetter gets called instead of colDef.field if you have a valueGetter defined Use value getters when retrieving the data requires more logic, including executing your own expressions (similar to what a spreadsheet. You should use colDef.field most of the time. Pulled from literally anywhere, including executing any expressions A Value Getter is a function that gets called allowing values to be pulled from literally anywhere, including executing any expressions you wish along the way. (The first time the grid is loaded - the value formatter is called only once with the real value) Strangely - the params.data does have the real value in its map. This happens when updating the grid with new data. Let's say you have 2 separate fields displaying First Name and Last Name and you want to have a derived field to show full name, you would use a valueGetter for this new field to concatenate First Name and Last NameĪ Value Getter is a function that gets called allowing values to be The ValueFormatter is called twice - once with params.value undefined and then again with the real value. Value getter should be used when you want to have custom logic when sourcing data for your ag grid field. ![]()
