RangeValidator control

Hi Rajesh,

RangeValidator for Age Field

RangeValidator validates the input to fall between the specified range of MinimumValue and MaximumValue property. We can also mention the validation data type through the Type property of the RangeValidator. The code for creating and binding a RangeValidator with GridView control is as follows
RangeValidator rangevalidator = new RangeValidator();
rangevalidator.ID = "RangeValidator1";
rangevalidator.ControlToValidate = "TextBox3";
rangevalidator.ErrorMessage = "Invalid Age";
rangevalidator.MaximumValue = "100";
rangevalidator.MinimumValue = "0";
rangevalidator.SetFocusOnError = true;
rangevalidator.Type = ValidationDataType.Integer;
e.Row.Cells[2].Controls.Add(rangevalidator);
