Hi Wenkai,

Thanks for your update.

We have analyzed your query and you can achieve your requirement “To apply filter for listbox element in GridTemplateColumn” by using the below code snippets. Since, if we keep any of the Edit elements in the CellTemplate then it will break the virtualization behavior while scrolling the data and reusing the same row to populate another data. Thereby, we have used the TextBlock as a CellTemplate and loaded ListBox as an EditTemplate.
  

<Syncfusion:GridTemplateColumn MappingName="EmployeeName" FilterPopupStyle="{StaticResourcefilterControlStyle}">  

    <Syncfusion:GridTemplateColumn.CellTemplate>  

        <DataTemplate>  

            <TextBlock Text="{Binding EmployeeName, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"/>  

        </DataTemplate>  

    </Syncfusion:GridTemplateColumn.CellTemplate>  

    <Syncfusion:GridTemplateColumn.EditTemplate>  

        <DataTemplate>  

            <ListBox ItemsSource="{BindingDataContext.EmployeeList,ElementName=sfdatagrid,Mode=TwoWay}" SelectedValue="{Binding EmployeeName}">  

            </ListBox>  

        </DataTemplate>  

    </Syncfusion:GridTemplateColumn.EditTemplate>  

</Syncfusion:GridTemplateColumn>
