Apply < or > filter to column

I have a list of objects that have int parameters that are separated into columns and I would like to filter those columns by a < or > value. I was wondering how I might be able to get this done. The data should only be displayed if the value is above or below a specific int value. I think I can do this with a HeaderTemplate or FilterTemplate but I'm not sure how. Thanks.

<RadzenGrid   Style="min-width: 100px; max-width: 100px; border: 1px solid black;" 
AllowFiltering="false"  AllowPaging="true" AllowSorting="false" 
Data="@_stResultList.Where(i => i.StateTest.subject == item && i.Date.date1.Year == year)" 

           foreach (var filter in multipleValues)
            <RadzenGridColumn Width="20px;" TItem="Webadmin.Models.Schools01.StateTestResult" Property="@filter" Title="@(filter)">


Hi @HRichard,

I think you should filter your data instead. Something like this:

_stResultList.Where(i => i.StateTest.subject == item && i.Date.date1.Year == year && i.Value > TargetValue)

I will give this a try, thank you!
