Dude, check your string/DateTime format you inserting. The DateTime field in SQL 2000 does not have a length validator, but it might be expecting just the date. So from what i know is that one should always check to see if the DateTime input is being formatted correctly, this is because some asp.net dateTime members may be inserting a default time of 12:00 after the date itself. Also make sure that the field you are updating on SQL side is actually a Date field. Hope i helped you mate. Good luck. Gimmmme some cheese $Shucks | :-\$

Validating File Upload Control with Regular Expression Validator

I have a fileupload control and a Regular expression validation control in my page. The requirement is user can upload only a word or pdf file, which is working fine. There is also a upload button, which when finishes with upload gives the message that 'Document Uploaded successfully'. This also working fine.

My issue is, if the user again clicks on browse button (after uploaded the file successfully) in FileUpload Control and checks any file other than doc or pdf file, both the messages are displaying:"Only doc or PDF file should be uploaded" and "Document uploaded successfully". This looks weird.

Any idea how to overcome this? I tried to write servevalidate events but it's not firing at all. Anybody provides any idea on this? Thanks for the help.

My guess is you do not return from the function if the validation fails.

But it would be nice, if you can post your code so that exact problem can be looked upon.

Here is the code:

<asp:Button ID="DocumentUploadButton" runat="server" OnClick="DocumentUploadButton_Click"
Text="Upload" Height="21px" Width="80px" /></td>

<tr><td><asp:CustomValidator ID="DocumentUploadedCustomValidator" runat="server" Display="Dynamic" CssClass="labeltext"
ErrorMessage="<"Document must be uploaded %>"
OnServerValidate="DocumentUploadedCustomValidator_ServerValidate" ></asp:CustomValidator>
<asp:RegularExpressionValidator ID="DocumentUploadExpressionValidator" runat="server" CssClass="labeltext"
ControlToValidate="DocumentFileUpload" Display="Dynamic"
ErrorMessage="<"Only PDF or Word files is allowed."%>"
ValidationExpression="[a-zA-Z\\].*(.doc|.DOC|.docx|.DOCX|.pdf|.PDF)$"></asp:RegularExpressionValidator>

</td>
</tr>

protected void DocumentUploadedCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
{
CustomValidator cv = (CustomValidator)source;
args.IsValid = !String.IsNullOrEmpty(System.Convert.ToString(ViewState["DocumentFileId"]));

}

protected void DocumentUploadButton_Click(object sender, EventArgs e)
{
PDFFilename = Path.GetFileName(DocumentFileUpload.PostedFile.FileName);
int FileExtensionIndex = PDFFilename.IndexOf(".");
PDFFilename = PDFFilename.Substring(0, FileExtensionIndex);
PDFFilename += ".pdf";
ViewState["PDFFilename"] = PDFFilename;
Guid g = AddFile(DocumentFileUpload.FileBytes, PDFFilename);
File.Delete(PDFSaveLocation);
ViewState["DocumentFileId"] = g;
DocumentUploadedCustomValidator.IsValid = true;

if (ViewState["DocumentFileId"] != null)
{
DocumentUploadedLabel.CssClass = "SuccessMessagesLabel";
DocumentUploadedLabel.Text = "Document Uploaded Successfully";
}
else
{
DocumentUploadedLabel.CssClass = "ErrorMessagesLabel";
DocumentUploadedLabel.Text = "Document Upload Failed";
}}

How to specify Numeric Format i.e Numeric part and decimal part?

Hi ,

i want to specify the maximum number of digits for numeric part and the Decimal part in a text box.

i tried specifying precision and maxlength of the text box but then it if we input the max length then the precesion cannot be inputted and it gets resetted to the maxamount which should not be possible.

like if Maxlength=8

precsion = 2

input required:123456.90 possible

input required : 12345678.89 which is not possible

so is there any way we could specify the format of the numeric part and as well the decimal part. which would restrict for only that particular input format.

like : dddddddd.dd

thanks in advance....

cheers,

sriharsha

You can use regular expressions to do the validation.

In between, do you how to build a regular expression for this?

Hi ,

I used Regularexpression and its working fine.

as:

<asp:regularexpressionvalidator id="regexpName" runat="server"
errormessage="This expression does not validate."
controltovalidate="TextBox5"
validationexpression="^\d{1,8}(\.\d{1,2})?$" enableviewstate="true">;

in
controltovalidate : speicfy the textbox to validate
ValidationExpression: which validates the expression in the format (8,2)
otherwise gives error.

Thanks for all suggestions.

Please post your question little bit clear...

and as per my understand you want to fetch only one record from your table,
for that,
you have to write a query to fetch the particular one record according to your requirement...and bind it to your gridview...
