Implement the SQL sentence "IN" with the control. In order to filter the registers that have a value into a column defined into a list of values: [column] IN ('value1', 'value2'.'value3')
We added two new filter descriptors for string type: "Is in list" and "Not in list". The code snippet below demonstrate how can build the expression: this.radDataFilter1.Expression = "[Country] NOT IN ('Canada','Sweden','Germany')"
