Hi Ivan, 

Thanks for contacting Syncfusion support. 

We suggest you to set the “Type” property for the corresponding column to overcome the problem you are facing.  
 
By default the type for the corresponding column type will be defined based on first record value of the particular column’s data. If the first row data for the column is empty then the type for the column will not be set by default and so the script error will occurred when try perform filter in Grid.  

So to overcome the problem, kindly specify the type for the column using Type property. Please refer the code below, 

 
<EjsGrid @ref="Grid" @ref:suppressField DataSource="@Orders" AllowFiltering="true" AllowPaging="true" Height="315"> 
    <GridColumns> 
       <GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Type="number" Width="120"></GridColumn> 
        ... 
    </GridColumns> 
</EjsGrid> 

@code{ 
    ... 
   protected override void OnInitialized() 
    { 
        Orders = Enumerable.Range(0, 4).Select(x => new Order() 
        { 
            OrderID = 1000 + x, 
            CustomerID = (new int?[] { null,8, 9, 10, 11 })[x], //null value for first row data, so it is must to define the Type for “CustomerID” column. 
            ... 
       }).ToList(); 
    } 
    ... 
}
