devextreme设置DxDataGrid自定义headerFilter的初始筛选器值

Question

如果包含这样的自定义表达式，如何设置起始headerFilter值？设置filterValues="xxx > 0"不起作用

<dxi-column caption="" dataField="xxx" [headerFilter]="headerFilter" filterValues="xxx > 0"></dxi-column>

headerFilter: any = {
dataSource: [ {
text: "to do",
value: ["xxx", "=", 0]
}, {

text: "done",
value: [["xxx", ">", 0]]
},]
};

Answer 1

您调用过滤器值的方式不对。尝试以下操作：

<dx-data-grid ...
[filterSyncEnabled]="true"
[filterValue]="['xxx', '>', 0]"> 
<dxo-header-filter 
[visible]="true">
</dxo-header-filter>
<dxi-column caption="" dataField="xxx" [headerFilter]="headerFilter">
</dxi-column>
...
</dx-data-grid>
