Bug with Grid's PredicateModel detection

[Ivan]

Hello!
Next bug:

The grid incorrectly determines the predicatemodel if you switch between filters without closing the previous popup filter.

Click on the date column filter icon, then without closing the filter click on the integer column filter icon.

The predicatemodel's type is still datetime but not integer as expected.

Therefore, it is impossible to bind to the predicatemodel value as runtime errors occur

<SfGrid TValue="Order" AllowFiltering="true">

    <GridFilterSettings Type="Syncfusion.Blazor.Grids.FilterType.Menu" ShowFilterBarStatus="true" />

    <GridColumns>

        <GridColumn Field="@nameof(Order.Id)">

            <FilterTemplate>

                @{

                    GetPredicateType(context);

                }

            </FilterTemplate>

        </GridColumn>

        <GridColumn Field="@nameof(Order.Date)">

            <FilterTemplate>

                @{

                    GetPredicateType(context);

                }

            </FilterTemplate>

            </GridColumn>

    </GridColumns>

</SfGrid>

@code{

    private void GetPredicateType(object obj)

    {

        Debug.WriteLine(obj.GetType());

    }

    public class Order

    {

        public int Id { get; set; }

        public DateTime? Date { get; set; }

    }

}

Hi Ivan,  

 

Thanks for explaining the reported issue with video demo. 

 

Query: “You probably reproduced the bug incorrectly. It is also present in your example.” 

 

We have validated the reported issue and we are able to reproduce the reported issue at our end in the provided sample. We have considered it as a bug and logged the defect report for the same “FilterTemplate Context value returns same type for different columns of different datatype”. Thank you for taking the time to report this issue and helping us improve our product. Fix for the issue will be included in our weekly patch release which is expected to be rolled out by mid of October, 2020.  

 

You can now track the current status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.

Once the above issue is resolved, kindly define the context of FilterTemplate like below (i.e.) type cast the PredicateModel based on column type 

 

<SfGrid TValue="Order" DataSource="Orders" AllowFiltering="true"> 

    <GridFilterSettings Type="Syncfusion.Blazor.Grids.FilterType.Menu" /> 

    <GridColumns> 

        <GridColumn Field="@nameof(Order.Id)"> 

            <FilterTemplate> 

                @{ 

                    GetPredicateType("integer", (context as PredicateModel<int>)); 

                } 

            </FilterTemplate> 

        </GridColumn> 

        <GridColumn Field="@nameof(Order.Date)"> 

            <FilterTemplate> 

                @{ 

                    GetPredicateType("DateTime", (context as PredicateModel<DateTime?>)); 

                } 

            </FilterTemplate> 

        </GridColumn> 

    </GridColumns> 

</SfGrid> 

  

  

@code{ 

    private void GetPredicateType(string caller, object obj) 

    { 

        Debug.WriteLine($"caller: {caller} - {obj?.GetType()}"); 

    } 

 

 

Till then we appreciate your patience.
