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 ...)
What is the best way to debug a CompareValidator that always fails the validation? Is there any way to see what the values are that it's comparing to maybe get a clue as to what's going wrong?
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.
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?
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.
I am using a master page and I need to change how the <title> element is rendered. The <title> content renders as expected. The problem is the whitespace that bounds my <title> element. I want to get rid of it.How do I remove the leading and trailing characters
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
protected void btnExportExcel_Click(object sender, EventArgs e) { Â Â Â Â Response.Clear(); Â Â Â Â Response.Buffer = true; Â Â Â Â Â Â Â Â Response.AddHeader("content-disposition", Â Â Â Â Â "attachment;filename=GridViewExport.xls");
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.
How do I validate RequiredFieldValidator/CompareValidator conditionally. I have aded equiredFieldValidator/CompareValidator on date textbox. I want that if textbox1="No" thne it should not validate or compare date text box, if textbox1="Yes" then it should validate.
Is this possible on form submit button or any other way?
i have 2 texztboxes for password function. Now i want to use the customvalidator to compare the 2 textboxes instead of the comparevalidator. I used a cs code like this bloew, but it doesnt work.
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.
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 realized this has been asked multiple times before, but I still haven't been able to get it to work. I'm trying to export a Gridview to Excel without losing leading zeros. Here is my code. Add added the STYLE lines to try to fix the problem.
Dim attachment As String = "attachment; filename=Awards.xls" System.Web.HttpContext.Current.Response.ClearContent() System.Web.HttpContext.Current.Response.AddHeader("content-disposition", attachment) System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel" Dim sw As New StringWriter() Dim htw As New HtmlTextWriter(sw) gv.RenderControl(htw) System.Web.HttpContext.Current.Response.Write(sw.ToString()) Dim STYLE As String = "<style> .text { mso-number-format: ; } </style> " System.Web.HttpContext.Current.Response.Write(STYLE) System.Web.HttpContext.Current.Response.[End]()
I 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?
i have a asp.net web site with it we have admin area with login page for admin only and all site is allowed for all - i need to ask how to define the right security configuration for it as i get this error Cannot use a leading .. to exit above the top directory.

I'm currently having an issue with asp net mvc and iis7 rewrite module. I'm rewriting a page from /kw.htm to /Listing/Search. And when it renders I have an exception that says "Cannot use a leading .. to exit above the top directory" I thought this scenario was now handle with the iis7 rewrite module. Did I miss something ?
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.
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?
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.
