#Remarks

Handle the CustomizeFilterRowEditor event to customize filter row editors separately from data row editors. The following example hides clear buttons in filter row editors displayed for Task and Employee Name columns:

@inject EmployeeTaskService EmployeeTaskService

<DxTreeList Data="TreeListData"
            KeyFieldName="Id"
            ParentKeyFieldName="ParentId" 
            ShowFilterRow="true"
            CustomizeFilterRowEditor="TreeList_CustomizeFilterRowEditor">
    <Columns>
        <DxTreeListDataColumn FieldName="Name" Caption="Task" />
        <DxTreeListDataColumn FieldName="EmployeeName" />
        <DxTreeListDataColumn FieldName="StartDate" />
        <DxTreeListDataColumn FieldName="DueDate" />
    </Columns>
</DxTreeList>

@code {
    List<EmployeeTask> TreeListData { get; set; }

    protected override void OnInitialized() {
        TreeListData = EmployeeTaskService.GenerateData();
    }
    void TreeList_CustomizeFilterRowEditor(TreeListCustomizeFilterRowEditorEventArgs e) {
        if(e.FieldName == "Name" || e.FieldName == "EmployeeName") {
            var settings = e.EditSettings as ITextEditSettings; 
            settings.ClearButtonDisplayMode = DataEditorClearButtonDisplayMode.Never;
        }
    }
}
