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 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>

Web Forms :: Is Using Both A Required Field Validator And A Compare Validator

Mar 1, 2010

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?

Web Forms :: Compare Validator Be Used To Be Sure To Values Aren't The Same?

Jun 25, 2010

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:


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.

Web Forms :: Compare Validator - Error Label Still Visible

Dec 22, 2009

I have an intranet site. To add a new record to the db I have 3 pages, each with a segment of a new record and each dependent on the level of the user. I use both a Require and Compare Validator for that input. For Compare there are numerical totals categories. There are also sub-categories for numerical input. The sub-categories should not exceed their respective totals. The Require & Compare Validators work fine. However, I did not use those for another category. I used the following code - the problem is that if an "error label" appears and the user navigates to the next page then uses the back button to return to that page the "error label" is still visible.

The code:
Private Function Verify() As Boolean
Dim intReg As Integer = 0
Dim intOT As Integer = 0
Dim BlnPass As Boolean = True
Dim BranchRegTotals As New Dictionary(Of String, Integer)
Dim BranchOTTotals As New Dictionary(Of String, Integer)
If chkDVTT.Checked = True Then
intReg += Val(txtDVTTRegHrs.Text)
intOT += Val(txtBrDVTTOTHrs.Text)
BranchRegTotals.Add("DVTT", Val(txtDVTTRegHrs.Text))
BranchOTTotals.Add("DVTT", Val(txtBrDVTTOTHrs.Text))
End If
If chkLM.Checked = True Then
intReg += Val(txtBRLMRegHrs.Text)
intOT += Val(txtBrLMOTHrs.Text)
BranchRegTotals.Add("LM", Val(txtBRLMRegHrs.Text))
BranchOTTotals.Add("LM", Val(txtBrLMOTHrs.Text))
End If

Web Forms :: Compare Validator - Fires Error Message

Mar 17, 2010

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:
