on button click i used to validate my dropdownlist i set validation group also.. but its not working why...
I have 2 text boxes in which I am comparing the numeric value of one to the other. At first it works fine and I get the appropriate error message. But eventually as i plug in different numbers although I should be getting an error message I stop getting one. Is there something going on behind the scenes to fire the error message than I am unaware of. Also the error message fires some time when the value is less than the value of another control and equal to the value. I only want it to fire when it is less than the value of the other control.

I have a text for user inputs Date. There is a CompareValidator which is used to compare Date between 2 TextBoxes. User do not need to input separator. After finish inputting value, he presses Tab to call a Javascript function to Format value of this Textbox.
Ex : user inputs
TextBox1 (From) : 01012010 =>Press TAB =>Value : 01/01/2010.
TextBox2 (To) : 01022010 =>Press TAB =>Value : 01/02/2010.
But Compare Validator show Error after cursor leaves the TextBox2. If I choose these values from Date Picker => No problem.
I think Compare Validator is called before onblur event. Is that right?
If it is right, is there any way to do my work?
Using a CompareValidator control in GridView. I am validating a value by comparing it to another value found at different cell at edit time. My code found below and perfectly working as expected. Now, how to further make this code to dynamically work based on a flag (checkbox) found in a third cell?
Via RowDataBound
[Code]....
To elaborate more, here is my pseudo code example
If the FLAG cell is checked then, any input number should pass the validation. The Checkbox value is unchecked by default.

I have two textboxes and a CompareValidator attempting to ensure that TextBox_1 contains a date that comes on or before the one in TextBox_2. When one textbox contains a date in "MM/dd/yyyy" format, and the other uses "M/d/yyyy", and the only difference between the two is a leading zero in the "MM" part, my validator fails to recognize that the dates are equal.
I've solved the problem by using the same format for both, but I'm wondering what's going on.
(I'd post the code, but there are so many layers -- controls using inherited classes, etc. -- that it would be more than a bit difficult to make sense out of ...)
I created a UserControl and added a public DateTime property. I want to set this property in Markup (ie. <cc1:MyControl runat="server" id="MyControl1" DateTimeProp="1/1/2010" /> ) however I live in a place with a dd/mm/yyyy date format so it complains if I set something like "20/1/2010". Is there a way to set markup in my local datetime format or do I have to conform to "mm/dd/yyyy"?
View 2 RepliesI have two textboxes where the user will input integers - i need to do a validation on these textboxes: txtStartIndex should be less than txtEndIndex - this works except with either one of the textboxes is left empty/blank how can i fix this?
<td align="right">
<asp:TextBox ID="txtStartIndex" runat="server" Width="50px"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtStartIndex" ErrorMessage="*" ValidationExpression="[0-9]*" ToolTip="Numeric Values Only"></asp:RegularExpressionValidator>
<td align="right">
<asp:TextBox ID="txtEndIndex" runat="server" Width="50px"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server" ControlToValidate="txtEndIndex"ErrorMessage="*" ValidationExpression="[0-9]*" ToolTip="Numeric Values Only"></asp:RegularExpressionValidator>
<asp:CompareValidator ID="compareValidator1" ControlToValidate="txtEndIndex" ControlToCompare="txtStartIndex"Operator="GreaterThan" Type="Integer" Text="*" runat="server" ToolTip="EndIndex has to be greater than StartIndex" />
</td>
obj.From = DateTime.Parse(txtFrom.Text, ci);
And it will give error String was not recognized as a valid DateTime. How it can be solved..

There are a lot examples of validation but with ControlToValidate as textBox or label, What about more complex Controls, is there any way I can tell which property from that control has to be used?
Maybe Client side validation ? But how to do this ?
I have a compare validator to validate an entry of course. And so, I set my compare validator to validate a textbox and its type to DOUBLE. Even if I input a double value (i.e. 150.24) on the text box, still the page cannot proceed on the next statement because the error message of the validator always display.

I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
I have an XML string which contains Dates formatted "dd/MM/yyyy hh:mm:ss".
I'm loading this XML into a dataset using DataSet.ReadXml().

I have a salary TextBox and an associated CompareValidator, which is setup as follows:
<asp:CompareValidator ... Operator="DataTypeCheck" Type="Currency" />
I fill the TextBox with a formatted string out of the database:
txtSalary.Text = myObject.Salary.ToString("N2")
When a user accesses the page using a French culture (such as fr-ca), the ToString method will put 80 000,00 in the textbox, which is fine.However, any number with a space in it causes the validator to fail, which is not fine. Is there any way to make the CompareValidator work properly with non-US formatted numbers?
I have the following template defined within DetailsView ( DetailsView is bound to object data source ):
<EditItemTemplate>
<asp:TextBox ID="txtReleaseDate" runat="server"
Text='<%# Bind("ReleaseDate", "{0:d}") %>'>

<asp:CompareValidator ID="valReleaseDateType" runat="server"
ControlToValidate="txtReleaseDate" Type="Date" Operator="DataTypeCheck"
Display="Dynamic" > *

Assuming I enter into TextBox txtReleaseDate a date in format month/day/year, then upon clicking an Update or Insert button, a CompareValidator control complains that date format is not valid. But if I enter date in format day/month/year, then object data source throws an exception Cannot convert value of parameter 'releaseDate' from 'System.String' to 'System.DateTime', while CompareValidator doesn't complain. I need the two controls to accept the same date format, so:
a) Since my DB stores date in format day/month/year, the best option would be for ODS to also accept this as valid date format. Can ODS be configured that way?
b)Can CompareValidator be configured to also accept month/day/year format?
