Spread 提供了验证机制-DataValidator:
- gcSpreadSheet1.HighlightInvalidData = true;
- var valid = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateListValidator("5,10,15,20");
- gcSpreadSheet1.Sheets[0].Cells[0, 1].DataValidator = valid;
- gcSpreadSheet1.Sheets[0].Cells[0, 0].Text = "5, 10, 15, and 20 are valid numbers.";
-
- var valid1 = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateNumberValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.GreaterThan, "5", "20", true);
- gcSpreadSheet1.Sheets[0].Cells[1, 1].DataValidator = valid1;
- gcSpreadSheet1.Sheets[0].Cells[1,0].Text = "A number greater than 5 is valid.";
- var valid2 = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateTextLengthValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.GreaterThan, "4", "20");
- gcSpreadSheet1.Sheets[0].Cells[2, 1].DataValidator = valid2;
- gcSpreadSheet1.Sheets[0].Cells[2, 0].Text = "Type more than four characters.";

并且可以通过 ValidationError 来接收错误输入字符。 |
