You can use the columns.filterTemplate property to define custom component in advanced filter UI from excel filter for a particular column.

The following example demonstrates the way to use filter template for a column when using excel filter. In the following example, the DropdownList component is used to filter CustomerID column using filter template.

    public filterOption: FilterSettingsModel = { type: 'Excel' };
    public dropdata: string[] = DataUtil.distinct(data, 'CustomerID') as string[];
    public fields: object = { text: 'CustomerID', value: 'CustomerID' };
    public height = '220px';

  • By default, while opening the excel/checkbox filter in the Grid, the filter dialog will get and display the distinct data from the first 1000 records bound to the Grid to optimize performance. The remaining records will be returned as a result of the search option of the filter dialog.
  • However, we can increase the excel/checkbox filter count by modifying the filterChoiceCount argument value(as per our need) in the actionBegin event when the requestType is filterchoicerequest or filtersearchbegin. This is demonstrated in the below code snippet,

actionBegin(args: FilterEventArgs) {
    if (args.requestType === "filterchoicerequest" || args.requestType === "filtersearchbegin") {
        args.filterChoiceCount = 3000;
