FilterElement.FilterModelTemplateSelector Property

Gets or sets a template selector that applies a visual template to the filter element based on its model type.

Namespace: DevExpress.Xpf.Core.FilteringUI

Assembly: DevExpress.Xpf.Grid.v26.1.dll

Declaration

C#

public DataTemplateSelector FilterModelTemplateSelector { get; set; }

VB.NET

Public Property FilterModelTemplateSelector As DataTemplateSelector

Property Value

Type	Description
DataTemplateSelector	A DataTemplateSelector that selects a visual template based on the filter element’s model type.

Remarks

Use FilterModelTemplateSelector when a filter element can produce different model types depending on the underlying column type. Unlike FilterModelTemplate that applies a single template regardless of the model type, FilterModelTemplateSelector allows you to define distinct editor templates for each supported model type.

The selector receives the current FilterModel instance as a data item. Use the model’s type to return the appropriate template.

Note

FilterModelTemplateSelector has priority over FilterModelTemplate when both properties are assigned.

Example: Create Different Filter Models Based on Column Types

A DateRangeFilterElement creates different filter models depending on the column type:

• DateRangeFilterModel for DateTime columns
• DateOnlyRangeFilterModel for DateOnly columns
• TimeOnlyRangeFilterModel for TimeOnly columns

Use FilterModelTemplateSelector to assign a dedicated editor template for each model type:

Xaml

<dxfui:DateRangeFilterElement FieldName="OrderDate"
       Context="{Binding FilteringContext, ElementName=grid}">
    <dxfui:DateRangeFilterElement.FilterModelTemplateSelector>
        <dxfui:DateRangeFilterModelTemplateSelector
            DateTimeRangeTemplate="{StaticResource DateRangeEditorTemplate}"
            DateOnlyRangeTemplate="{StaticResource DateOnlyEditorTemplate}"
            TimeOnlyRangeTemplate="{StaticResource TimeOnlyEditorTemplate}" />  
    </dxfui:DateRangeFilterElement.FilterModelTemplateSelector>
</dxfui:DateRangeFilterElement>
