[Regression] Filterable Grid throws if a column field is not bound to a field from the model

In a filterable Grid, if a column is not bound to a field from the model the Grid uses, it throws with:

Error: System.ArgumentNullException: Value cannot be null. (Parameter 'nullableType')

Reproduction: https://blazorrepl.telerik.com/GyEUlFEs04AUJoJ601.

The issue is reproducible :

For `FilterRow` - on initialization even if the column is not filterable.
For `FilterMenu` - on initialization when the column is filterable.

A possible workaround for the time being is to set the FieldType of the column: https://blazorrepl.telerik.com/wSugvFui10jhcpZy00.

Hi Mike,

I confirm that the bug was fixed for the TreeList too. Here is a test page: https://blazorrepl.telerik.com/cyYCutaW43pc6IEb34

Please make sure the column has Filterable="false" and the app is actually using the latest version.

Regards,

This problem also occurs in TreeList, which inherits TableGridBase, but was not addressed in the 6.1.0 release.

@Dimo

Before we upgrade to v6 it was perfectly working.

Hi,

We tried to set Filterable = "true" for a column field that is not bound to a field from the model and getting "An unhandled error has occurred.Reload".
We are using following example: https://blazorrepl.telerik.com/wSugvFui10jhcpZy00

@Aldo

A Field configuration like @nameof(RequestListItem.M136.APMcsfirma) is invalid. It assumes that RequestListItem has a property APMcsfirma, which is not true. Please check the KB article about binding to nested (navigation) properties.

Hi, we have the same problem with columns bound to a subfield from the model.

RequestListItem is my model that has its fields, one of these is an object (M136) with fields

So, this works
<GridColumn Field="@nameof(RequestListItem.Field)"

This raise an exception even with the workaround (FieldType)

<GridColumn Field="@nameof(RequestListItem.M136.APMcsfirma)" FieldType="@typeof(string)"

The grid is showed but fields value is always null and if I click on column header to sort I get

Error: System.ArgumentException: Invalid property or field - 'APMcsfirma' for type: RequestListItem
