DataGrid custom Column FilterTemplate

Radzen.Blazor Components
1

I am using the datagrid component with a custom filter, just like in the example https://blazor.radzen.com/datagrid-filter-template.
The problem I have is when I filter through the custom filter I lose the values of the rest of the filter. Any idea how to solve this?

Possible solution will be to use the approach from this article:

Thank you enchev!
Indeed, the clue you sent me allowed me to achieve this with the following code:

public Dictionary<String, String> dicCurrentFiltro(RadzenGrid<Dom_HitoPlantilla> GridHitos) {

            Dictionary <String, String> dic = new Dictionary<String, String>();

            foreach (RadzenGridColumn<Dom_HitoPlantilla> c in GridHitos.ColumnsCollection) {
                if (c.FilterValue != null) {
                    dic.Add(c.Property, c.FilterValue.ToString());
                }
            }
            return dic;
        }

        protected override async Task OnAfterRenderAsync(bool firstRender)
        {
            //Aplicamos valores 

            foreach (RadzenGridColumn<Dom_HitoPlantilla> c in GridHitos.ColumnsCollection)
            {
                if (DicCurrentFiltro.ContainsKey(c.Property))
                {
                    c.FilterValue = DicCurrentFiltro.GetValueOrDefault(c.Property, null);
                }
            }
            GridHitos.Reload();

        }
