Hi:
Relatively newby to the world of ASP .Net.
I'm having issues trying to set the min/max values of the RangeValidator.
I'm trying to set these values dynamically as my page/control loads.
I'd like to set these values directly within the page using embedded JavaScript to
references variables from my code behind.
My ASP .Net code looks like this:
=======================
<asp:RangeValidator ID="rngNumberOfTravelers" runat="server"
ControlToValidate="tNumberofTravelers"
ErrorMessage="<%=RangeTravelersErrorMessage%>"
CssClass="error"
Display="Dynamic"
EnableClientScript="true"
MinimumValue="<%=MinNumber%>"
MaximumValue="<%=MaxNumber%>"
Type="Integer"/>
My property definition is C# looks like this:
==============================
private int _minNumber;
public int MinNumber
{
get {
return _minNumbers;
}
}
private int _maxNumber;
public int MaxNumber
{
get {
return _maxNumbers;
}
}
I get the following exception during the page load:
===================================
Server Error in '/Explorica.TravelerAdmin' Application.
--------------------------------------------------------------------------------
The value '<%=MaxNumberofTravelers%>' of the MaximumValue property of 'rngNumberOfTravelers' cannot be converted to type 'Integer'.

What am I doing wrong?
Can this not be set dynamically on the ASPX page?
I've also tried setting this in my code behind during Page_Load() <Binding the controls>.
But the result was that my RangeValidator did not fire correctly.
Any and all help will be much appreciated.
Thanks,
