I see. But if I want to get rid of one of the filtering trees, how would I do that?

In your example, if I wanted to get rid of this condition:

const productExpression = {

        condition: IgxStringFilteringOperand.instance().condition("contains"),

        fieldName: "ProductName",

        ignoreCase: true,

        searchVal: "Queso"

      };

But keep the second condition only after applying both condititons:

const productExpressions2 = {

        condition: IgxStringFilteringOperand.instance().condition("contains"),

        fieldName: "ProductName",

        ignoreCase: true,

        searchVal: "Cabrales"

      }

how would I do that?

Would I have to clear all conditions and apply only the ones I want to see?

Hi,

Yes I have tried that.

In this case when I want to filter out val '1' it would be:

const tree = new FilteringExpressionsTree(FilteringLogic.And);

    tree.filteringOperands.push({

        fieldName: 'Sort',

        condition: IgxNumberFilteringOperand.instance().condition('isNotEqual'),

        searchVal: 1

    });
this.grid.advancedFilteringExpressionsTree = tree;

So now we should get:

sort	column1	column2
2
2
3
3

And then when I want to filter out value '2' as well as value 1 at the same time it would be:

this.grid.advancedFilteringExpressionsTree.filteringOperands.push({

      fieldName: 'Sort',

      condition: IgxNumberFilteringOperand.instance().condition('isNotEqual'),

      searchVal: 2

    });

Which should result in:

sort	column1	column2
3
3

Is this the correct implementation?
