Hi,

I want to filter my data by some properties, so I use ejQuery's where clause to do it. Like this:

me.query = new ej.Query().where(new ej.Predicate("prod_order_reference", ej.FilterOperators.contains, $('#filterHighlightTextOp').val(), true)
                                                 .or("item_reference", ej.FilterOperators.contains, $('#filterHighlightTextOp').val(), true)
                                                 .or("item_name", ej.FilterOperators.contains, $('#filterHighlightTextOp').val(), true)
                                                 .or("customer", ej.FilterOperators.contains, $('#filterHighlightTextOp').val(), true)
                                                 .or("sale_order", ej.FilterOperators.contains, $('#filterHighlightTextOp').val(), true));

Doing it this way it only filters the first level of the data structure, but it doesn't filter the subtasks of a task.

For example, in the ej.Predicate, it first check the if "prod_order_reference" property contains a value. I want to check this in the parent task and in every child subtask, but it does only in the parent one.

How could I do this?

Thanks.

Hi Oscar,

We have analyzed the reported query. The reported issue may due to applying “ej.Query()” on a hierarchical data. To filter all the required records, we recommend self-reference data source. And using “filterSettings” property we can filter required columns on load time.

Please find the code example below:

[ts]

this.filterSettings = {

filteredColumns: [{

value: "5",

field: "TaskName",

operator: "contains",

predicate: "or"

{

value: "1",

field: "TaskName",

operator: "contains",

predicate: "or"

}]

}

[html]

<ej-gantt id="GanttControl"

//..

[filterSettings]="filterSettings">

</ej-gantt>

We have also prepared the sample based on this. Please find the sample from below location

Please let us know if you need further reference on this.
