Infragistics Grid ColumnFilter过滤基于2列值

Question

我有2列x和Y.我需要根据2列的值过滤网格.例如:假设我的过滤条件为真,那么它应检查两列的值,如果任何列值为true,则不应过滤该行.如果该值都不为真,则应该过滤该行.

Answer 1

我能想到一个快速解决方案.下面的代码将在2列上设置普通过滤器,然后您只需更改列LogicalOperator.

    private void Filter() {
        Infragistics.Win.UltraWinGrid.FilterCondition fc = new Infragistics.Win.UltraWinGrid.FilterCondition();
        fc.CompareValue = "someValue1";
        fc.ComparisionOperator = Infragistics.Win.UltraWinGrid.FilterComparisionOperator.Equals;
        ultraGrid1.DisplayLayout.Bands[0].ColumnFilters["col_x"].FilterConditions.Add(fc);

        Infragistics.Win.UltraWinGrid.FilterCondition fc2 = new Infragistics.Win.UltraWinGrid.FilterCondition();
        fc2.CompareValue = "someValue2";
        fc2.ComparisionOperator = Infragistics.Win.UltraWinGrid.FilterComparisionOperator.Equals;
        ultraGrid1.DisplayLayout.Bands[0].ColumnFilters["col_y"].FilterConditions.Add(fc2);

        // set the logical operator of the columns on the band
        ultraGrid1.DisplayLayout.Bands[0].ColumnFilters.LogicalOperator = Infragistics.Win.UltraWinGrid.FilterLogicalOperator.Or;
    }

这是你在找什么？
