Web Forms :: Date CompareValidator Fails When Leading Zero Is Missing?

Jul 8, 2010

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 ...)

Using The CompareValidator Control To Compare User Input Date With Today's Date?

Feb 15, 2010

i would like to compare the current date with the date entered by user..however, i'm encountering errors so far..

i tried something like this:

<asp:TextBox id="txtDate1" runat="server" />
<asp:CompareValidator runat="server" ErrorMessage="The date must be greater than today"
ControlToValidate="txtDate1" type="date"
ValuetoCompare="DateTime.Today.ToShortDateString()" />

and i got an error stating that the value of DateTime.Today.ToShortDateString() of the ValueToCompare property of "" cannot be converted to type 'date' i also tried ValueToCompare="DateTime.Now.Date()" and i got the same error message.

CompareValidator Control To Accept Date In Format Month / Day / Year

Jun 3, 2010

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

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?

Forms Data Controls :: Retain Values In A FormView When Validations Fails Or The SQL Fails On An Insert?

Oct 6, 2010

To me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.

As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.

I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.

Forms Data Controls :: Add Leading Zero In Formview Edititemtemplate?

Apr 28, 2010

I have a formview which binds to a table where one of the fields is an integer zip-code field. I want to pad the zip with a leading zero in the edit template when the zip is something like "02134". How do I edit the bound data without "breaking" the two-way binding?

I wrote simple function to add the zero and return a string:

Public
Function padZIP(ByVal zip
As
Integer)
As
String
Dim tmpStr
As
String =
CType(zip,
String)
If tmpStr.Length = 4
Then tmpStr =
"0" & tmpStr
Return tmpStr
End
Function

and I can call it in the itemtemplate fine:

<asp:Label
ID="ZipLabel"
runat="server"
Text='<%# padZIP(container.dataitem("Zip")) %>'
Width="30"
/>

but, trying to do that in the edititemtemplate breaks the binding?

Web Forms :: How To Use CompareValidator Validation Control

Jan 11, 2011

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.

Web Forms :: CompareValidator Is Called Before Onblur Event?

Jan 11, 2010

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?

Forms Data Controls ::Using A CompareValidator Control In GridView?

Apr 4, 2010

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.

Keep Leading Zeros In A OleDbDataAdapter?

Jan 13, 2011

I have understood there is no way to keep leading zeros in a OleDbDataAdapter?

Im trying to read some data from a text file with:

MyCommand = New System.Data.OleDb.OleDbDataAdapter("SELECT F7, F5, F9, F1 FROM " & System.IO.Path.GetFileName(bonnerfil.PostedFile.FileName), MyConnection)

I have managed to keep leading zeros if I add a Schema.ini file into the directory with column set to Char.

But, when having a Shema.ini the select statement reads from start to end of the file. As you see in my select statement I prefer/must have the coulumn 7 first being read and so on. This do work and I will have get the result I want. But for now it´s either - get the order of columns correct or have leading zeros.

how can I either have a Schema.ini that reads the file in the order I want, or keep leading zeros and not have the order I want.

Code:

GridView Is Trimming Leading Spaces?

Mar 25, 2010

The GridView in ASP.NET 2.0 is trimming the leading spaces from data coming from a SQLServer database. I have yet to find a way to keep it from doing that. The data in this particular view is being edited to remove such spaces, but only upon editing the row can any leading spaces be seen, meaning, at present, each row will have to be touched. With 12,000+ rows, that's a little much.

What little I've found on Google has mainly be concerned with trimming leading spaces. Is there a way to force GridView to show the data exactly as it is in the database, leading spaces and all?

C# - Data Reader Trimming The Leading Zeros?

Jan 13, 2011

I have a string coming from a stored procedure looks like '001234567'.

sqlCommand = new SqlCommand("csp_Bbp_OBN_GetBasePageList", BBConnection);
sqlCommand.CommandType = System.Data.CommandType.StoredProcedure;
sqlCommand.Connection.Open();
// Run the SQL statement, and then get the returned rows to the DataReader.
accReader = sqlCommand.ExecuteReader();............

In my case, from the stored procedure I am returning the varchar, after executing and reading it I am getting the value to basePage.GrouNum which is a string. So, I don't see where it is trimming the leading zeros.

Example: GroupNumber in the table is : "001234567"
BasePage.GroupNum after reading from DataReader : "1234567"

But, I do not want the leading zeros being trimmed.
