Class Details

[line 55]
TRangeValidator class

TRangeValidator tests whether the value of an input component is within a specified range.

The TRangeValidator component uses three key properties to perform its validation. The MinValue and MaxValue properties specify the minimum and maximum values of the valid range. The ValueType property is used to specify the data type of the values to compare. The values to compare are converted to this data type before the validation operation is performed. The following value types are supported:

  • Integer A 32-bit signed integer data type.
  • Double A double-precision floating point number data type.
  • Currency A decimal data type that can contain currency symbols.
  • Date A date data type. The format follows the GNU date syntax.
  • String A string data type.
Namespace: System.Web.UI.WebControls

Properties

  • MinValue, string, kept in viewstate
    Gets or sets the minimum value of the validation range.
  • MaxValue, string, kept in viewstate
    Gets or sets the maximum value of the validation range.
  • ValueType, string, default=String, kept in viewstate
    Gets or sets the data type (Integer, Double, Currency, Date, String) that the values being compared are converted to before the comparison is made.
