Web Forms :: Setting A Compare Validator To Compare With Control In Different Content Area
Jan 10, 2011
When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?
<asp:Content ID="Content4" ContentPlaceHolderID="leftForm" Runat="Server">
<asp:Label ID="lblStartTimeEnter" runat="server" Text="Start Time:" Width="100px"/>
<asp:TextBox ID="txtStartTime"runat="server" MaxLength="50" Width="250"/>
</asp:content>
<asp:Content ID="Content4" ContentPlaceHolderID="rightForm" Runat="Server">
<asp:label ID="lblEndDateEnter" CssClass="formMargin labelInput" runat="server" Text="End Date:" Width="100px"/>
<asp:TextBox ID="txtEndDate" CssClass="formMargin" runat="server" MaxLength="20" Width="250" ClientIDMode="Static"/>
<asp:CompareValidator ID="cvlDate" runat="server" ControlToValidate="txtEndDate" ControlToCompare="txtStartDate" Operator="GreaterThan" Type="Date" ErrorMessage="Start Date must be before End Date" > *</asp:CompareValidator>
</asp:content>

I am trying to check for a condition such that a date in an input control (textbox) is not greater from a date 1 years from current date(exactly) and also it should not be less than a date 1 year back from current date. for eg. if today's date is "21/dec/1990" then usen cannot enter a date in textbox which is less than 21/dec/89 and it should not be greater than 21/dec/1991. for this i first tried to confirm the greater than condition, i wrote the following code:
<asp:TextBox
ID="TxtSessionFrom"
runat="server"></asp:TextBox>
<asp:CompareValidator
ID="CompareValidator1"
runat="server"
ControlToValidate="TxtSessionFrom"
ErrorMessage="CompareValidator"
Operator="GreaterThanEqual"
Type="Date"></asp:CompareValidator>
CompareValidator1.ValueToCompare=(DateTime.Now.AddYears(1).ToString());
but this gave an error: The value '' of the ValueToCompare property of 'CompareValidator1' cannot be converted to type 'Date'.

When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?

All of the examples I can find show the compare validator being used to see if two values are the same. Validation is succesfull if these values are the same, such as password confirmation.I want validation to succeed if values are not the same. I want to use this to be sure that someone doesn't enter the same value for two phone number fields. I want the two values to be different. Can the compare validator be used for this? I wasn't able to find any properties or examples that used it in this way. If not, how should this be done?

I have compare validators that I build on the fly in code behind that validate textboxes that are also built up in the code behind:
[Code]....
These work fine until a postback occurs. After a postback they still validate the form (i.e. they don't let you postback) but the error message won't display.

I've got a booking form which allows users to pick dates. User clicks FromDate button which activates calendar control, they select date from calendar which then populates a textBox. I have a compare validator which checks that the SelectedDate is greater than the current date, if the SelectedDate is in the past then the validator fires error message. This works as fine, however, when the validator fires it disables the FromDate button so the user is unable to pick another date from the calendar as the focus goes to the TextBox which is being validated - how do I get around this? Here's the code:

I have an AJAX Calendar extender that puts the date in the textbox in this format: MMMM d, yyyy. I also have a compare validator control that does at DataTypeCheck for DATE. However, when the Calendar Extender enters the date as MMMM d, yyyy (eg. November 2, 2010) the compare validator doesn't like it. It only seems to like the date in the format MM/dd/yy. Not sure how to get this compare validator to accept the input format from the calendar extender?

I have a date textbox. It has three validators on it. One is RequiredFieldValidator, second is CompareValidator and the third is RegularExpressionValidator.
CompareValidator checks for LessThanEqual for current date. For example if user enters date greater then todays' then it should display error message. It does that.
Problems is if user enters invalidate e.g., 2009/05/0d then I see two error messages. One for invalid date and one for compare. In this specfic case I want to see only one error that 'Date is invalid'. But some how I see two mesages.

I have a compare validator datatypecheck that was set up to check the date entered. I am now changing this to check to make sure that the date/time entered is valid. I changed the binding to be the date and time. I am not seeing anything that I need to change on the compare validator.
When I run the program and enter a date and time into the textbox, it is giving me the error that it is an invalid date. What am I missing?

I have this compare validator:
<asp:CompareValidator ID="cpvBirthDate" Type="Date" ControlToValidate="txtBirthDate" Operator="DataTypeCheck" runat="server" ErrorMessage="Please enter a valid date in this format mm-dd-yy">
<img src="Images/ExclamationMark.gif" alt="Please enter a valid date in this format mm-dd-yy" />
</asp:CompareValidator>
It works on the clientside fine, but if a user has javascript disabled then it accepts 071873 which is not a date. Do I need to write a specific serverside function for this validator to work?

I have come unstuck with a simple compare validation.
I have the following code
<asp:TextBox ID="tbxHowMany" runat="server"
style="z-index: 1; left: 310px; top: 385px; position: absolute; text-align: center;"
Width="75px"></asp:TextBox>[code]....
So when a user enters a figure higher than 200, the validation appears.However, when I change this figure to say, 30, the validation remains. I must be doing something really stupid, I just don't know what!
UPDATE: I have also just noticed that this validation occurs when a number greater than '20' is entered into the checkbox. I'm not very confused. I am assuming this is a type issue?

add the validation controls to them.The first page has a series of text boxes with autopostback = true. I can put CompareValidators onto the form and assign them to the textboxes, and they seem to work right. On my second page, however, the controls are being built on the server using vb code. The CompareValidators seem to work on the client side. On the server side, however, the CompareValidators always have an IsValid property = true, even when the value of the textbox clearly violates the conditions. I've checked all the properties I can think of and I can't see any difference between these dynamically generated validators and the static ones I have on the first page, so I'm thinking there must be something else going on.
