Date format in RangeValidator

Question

I am using RangeValidator to validate date enter in textbox and its working fine with default date format but now i want the date format in \"dd/MM/yyy\" but its generating

Answer 1

MinimumValue & MaximumValue need to be set in the Page_PreRender event and appear to require the date format as "dd-MM-yy"...see last post on Rangevalidator Min Max Value error

protected void Page_PreRender(object sender, EventArgs e)
{
    RangeValidator1.MinimumValue = DateTime.Now.Date.ToString("dd-MM-yy");
    RangeValidator1.MaximumValue = DateTime.Now.Date.AddYears(90).ToString("dd-MM-yy");
}
