Expression containers

Some properties are also expression containers (ExpressionContainers). Expression containers can handle both normal strings and expressions. Qlik Sense support two different expression containers:

• StringExpressionContainer

• ValueExpressionContainer

String expression container

Example: Non-calculated string expression container

	  myTable.Properties.Title = "My Table Title";

Result:

	  string stringValue = myTable.Title;

Example: Calculated string expression container

	  myTable.Properties.Title = "=1+1";

Result:

	  stringValue = myTable.Title;

Value expression container

Example: Evaluated value expression container on gauge measure

            IGaugeMeasureAxis measureAxis = gauge.Properties.MeasureAxis;
            measureAxis.Max = "25";
            measureAxis.Max = 25d;
			
            measureAxis.Max = "=20+5";

            double value = gauge.MeasureAxis.Max;
