Filtering with custom column in Grid

Question

Good day !  I'm testing SF Grid for a real-time dashboard. One of the column is a simple custom control (let's name it "PriceControl") 
 that get a model as input param and displaying only a span label with 
decimal value, and this control has subscription to external event and 
it updates its decimal value each second.   
All is working fine

so far, but now I want to make a custom filter for this column: a checkbox that filter records where Price > 100.   I'm not sure I can use 
FilterTemplate  for a GridColumn without Field (since it's a template with child control inside). And also I didn't find a proper way to make a ref or some binding to
"PriceControl"

so I can use its value in the filter (each row in Grid has its own model and its own Price).  Is there any workaround for such scenario ?Best regards,Vadim.

Hi Vadim, 

Greetings from Syncfusion. 

We have validated your query with the provided details. You have rendered a custom column(Custom control which shows some custom values) and you don’t have Field for that custom column. We would like to inform you that the Grid operations(such as Filtering, sorting, etc) works based on the Field property defined in the GridColumn. So we need to define Field property to perform Grid operations. 

If we don’t provide Field property to GridColumn, then we could not able to perform Grid operations(Filtering, Sorting, etc).  

Please let us know if you have any concerns.

Rahul

Hi Rahul! OK. So it's limited only with Grid pre-defined fields. I'll try then to implement it in another way with Observable collection, where I gonna modify the calculated column to get the same effect as current 
PriceControl

does.   For now I have another question related to a bug.When I use built-in "Search" for Grid, it always loads the initial state of 
PriceControl and ignore the current state of it. It's definitely not the expected behavior. The "Search" function should only affect the visual part and just filter out the records, isn't it?
Best regards,Vadim.
