08 May 2023 / 2 minutes to read

You can customize the default settings of the components which are used in Menu filter by using params of filter property in column definition. In the below sample, TaskID and Duration Columns are numeric columns, while opening the filter dialog you can see that NumericTextBox with spin button is displayed to change/set the filter value. Now using the params option we hide the spin button in NumericTextBox for TaskID Column.
