Finally i found my problems

Some parts in my etc/di.xml file

<type name="{{Namespace}}\{{Module}}\Model\ResourceModel\{{Entity}}\Grid\Collection">
    <arguments>
        <argument name="mainTable" xsi:type="string">{{your-entity-table}}</argument>
        <argument name="eventPrefix" xsi:type="string">{{youreventprefix}}</argument>
        <argument name="eventObject" xsi:type="string">{{youreventobject}}</argument>
        <argument name="resourceModel" xsi:type="string">{{Namespace}}\{{Module}}\Model\ResourceModel\{{Entity}}</argument>
    </arguments>
</type>

<type name="Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory">
    <arguments>
        <argument name="collections" xsi:type="array">
            <item name="your_listing_data_source" xsi:type="string">{{Namespace}}\{{Module}}\Model\ResourceModel\{{Entity}}\Grid\Collection</item>
        </argument>
    </arguments>
</type>

No need this below

<virtualType name="{{Namespace}}\{{Module}}\Model\ResourceModel\{{Entity}}\Collection" type="Magento\Framework\View\Element\UiComponent\DataProvider\SearchResult">
    <arguments>
        <argument name="mainTable" xsi:type="string">{{your-entity-table}}</argument>
        <argument name="eventPrefix" xsi:type="string">{{youreventprefix}}</argument>
        <argument name="eventObject" xsi:type="string">{{youreventobject}}</argument>
        <argument name="resourceModel" xsi:type="string">{{Namespace}}\{{Module}}\Model\ResourceModel\{{Entity}}</argument>
    </arguments>
</virtualType>

New GridUI comes with some implement interface you can see in module-cms
Don't forget Grid Collection located in

{{Namespace}}\{{Module}}\Model\ResourceModel\{{Entity}}\Grid\Collection. This implement SearchResultInterface for get collection data of entity and populate all to your grid
