Inheritance

System.Object

FormulaParsingEventArgs

Namespace: Syncfusion.Calculate

Assembly: Syncfusion.Calculate.Android.dll

Syntax

public class FormulaParsingEventArgs : EventArgs

Remarks

Please note that this event may be raised more than once as a string is parsed.

Examples

Here is code snippets that show how to tell a engine to also treat any text in a formula cell that begins with a minus(-) or a plus(+) as formulas. The default behavior is to treat only text beginning with equal(=) as formulas.

	//subscribe to the event before any formulas are loaded into the grid...
    Engine.FormulaParsing += new FormulaParsingEventHandler(Engine_FormulaParsing);

	//Here is the handler code that adds an = if necessary so any string beginning with +, - or =
    //is treated as a formula.
      void Engine_FormulaParsing(object sender, FormulaParsingEventArgs e)
      {
          //allow cells starting with + and - to be treated as formula cells.
          if (e.Text.StartsWith("-"))
               e.Text = "=" + e.Text;
          else if (e.Text.StartsWith("+"))
               e.Text = "=" + e.Text.Substring(1);
      }
