This example will explain how to perform the calculation by defining the name for a cell or range of cells. Also, you can set and retrive the values in row and column index using ICalcData.
The below code explain how to create a class for set and retrive the values in row and column index using ICalcData,
public class CalcData : ICalcData
{
public event ValueChangedEventHandler ValueChanged;
Dictionary<string, object> values = new Dictionary<string, object>();
public object GetValueRowCol(int row, int col)
{
object value = null;
var key = RangeInfo.GetAlphaLabel(col) + row;
this.values.TryGetValue(key, out value);
return value;
}
public void SetValueRowCol(object value, int row, int col)
{
var key = RangeInfo.GetAlphaLabel(col) + row;
if (!values.ContainsKey(key))
values.Add(key, value);
else if (values.ContainsKey(key) && values[key] != value)
values[key] = value;
}
public void WireParentObject()
{
}
private void OnValueChanged(int row, int col, string value)
{
if (ValueChanged != null)
ValueChanged(this, new ValueChangedEventArgs(row, col, value));
}
}The below code will explain how to set the data value of a specified cell range,
CalcData calcData = new CalcData();
CalcEngine engine = new CalcEngine(calcData);
// To set the data value of a specified row and column.
calcData.SetValueRowCol(90, 1, 1);
calcData.SetValueRowCol(50, 1, 2);
calcData.SetValueRowCol(100, 1, 3);The below code will explain how to define the name for range of cells and perform the calculation,
// Adding the name to the named range collection,
engine.AddNamedRange("GROUPCELLS", "A1:C1");
// Using the name for computing formulas,
string formula = "SUM(GROUPCELLS)";
string result = engine.ParseAndComputeFormula(formula);The output of calculation with values based on cell ranges,
