Question

Does anyone know there have any way that I can set the minimumvalue and the maximumvalue in the server side for asp:RangeValidator .net c#

Example:
I have the following code, instead of hard coding the minimumvalue and the maximumvalue, any way that I can set those value during the page load?

<asp:RangeValidator runat="server" id="rngDate" controltovalidate="txtDate" type="Date" minimumvalue="01-01-2011" maximumvalue="26-05-2011" errormessage="Please enter a valid date !" />

Answer 1

Yes, just set the MinimumValue and MaximumValue properties in the Page_Load. First, change your declaration of maximumvalue in your sample code to maximumvalue="05-26-2011" (the way you have it in the sample caused an ASP.NET exception in my test). Then, just do something like this in the Page_Load:

protected void Page_Load(object sender, EventArgs e)
{
    rngDate.MinimumValue = "05/01/2011";
    rngDate.MaximumValue = "05/20/2011";
}

It should work fine. If it’s not, then maybe something else is going on in your page.
