Hi in sql, "identity column" will automatically increase the value of its own, wenever other columns getting the value.

But in my case i have mentioned my column datatype as varchar, so "identity" wont work out here.

i want to insert my datas like this format for my ID Column,

ID
V00000001
V00000002
V00000003
.
.
.
V00000023

how to achieve using asp.net

Thanks & Regards,

If the data always begins with "V" I would use the idendity column and concatenate either in a calculated column or in my data/business layer to form the field.

Otherwise, add an insert trigger to the table and use string functions to convert to a number, find the next in the sequence, then insert the column.

Before inserting, get the max Id number from your database, increment it by 1 (or your wish) and then insert a new record in the table using an incremented Id.

You gona have to do some logic for the correct number of zeros to be put before the actuall number.

For that, you have to do the following.....
1) First retrieve the max id from your database.
2) Then convert the number part of data i.e. 00000001 to int.
3) Then increment it.
4) According to the number, concatenate that number of 0's and V to the incremented number.
5) Insert this id to your database.
6) Enjoy!

The ASAP.NET field validaators are run with JavaScript on the client first, then on the server if you have a Server meethod defined. Use some JavaScript to test when you click your submit button, or whatever method you are using to submit the form.

function ValidatePage()
{
  return Page_Validate("VALIDATION GROUP NAME");
}

You can try using a CustomValidator[^].

Thanks Mark Nischalke and Shameel

I added a CustomValidator to the textbox and add ClientValidationFunction

This is my solution to share with other people those who have problem as mine

ASP.NET

<asp:CustomValidator ID="CustomValidator1" runat="server" 
                                      ClientValidationFunction="CheckPorts" ControlToValidate="txtPort" 
                                      ErrorMessage="Please checked at checkbox or enter Port code in textbox." ValidateEmptyText="True"  
                                      ValidationGroup="RegisterAgentUser">*</asp:CustomValidator>

ValidateEmptyText="True" also important here, if not control will not doing validation.

function CheckPorts(sender, args) {
        var chk = document.getElementById('<%= CType(CreateUserWizardStep1.ContentTemplateContainer.FindControl("chkViewAll"), CheckBox).ClientID %>')
        if (args.Value == "" && chk.checked == false) {
            args.IsValid = false;
             }
        else {
            args.IsValid = true;
        }
    }

How to get data from generic handler after file download

Dominick Marciano7-Aug-11 15:36

Currently I have a page with a button on it. When the button is clicked a query string is passed to generic handler. The purpose of this handler is to generate letters for individual students that were in a class (the query string is the class id). As the files are generated they are added to a zip file so the user only has to download one file. Everything works perfectly fine including the downloading of the file.

However my problem is I need a way to know when the handler has finished and to retrieve data from it. Specifically, as the handler is looping through all the students it may find that some students do not have all the necessary data saved in the database in order to generate the appropriate letter. In this case the students name is save in a List(Of String) so that it can inform the user, but continues creating the rest of the letters.

I have tried using HttpContext.Current.Items.Add("BlankStudents", BlankStudentRecords) and HttpContext.Current.Session("BlankStudents") = BlankStudentRecords in order to save the list. The latter did not work because it says the object is not set to an instance and I'm assuming it is referring to the session. The former did work, however the ASP page that calls the handler does not post back so it can't try and read from the HttpContext.

I tried using a redirect but I get a "Cannot redirect after HTTP headers have been sent" because this redirect is being done after the zip file is transmitted to the client. What would be the best way to accomplish this? Would it be better to add the zip file and the List(Of String) both to the HttpContext.Current.Items and then redirect back to the page and initiate the download from there, or is there an even better and efficient method.

Thanks in advance for any help or suggestions.

As per my knowledge and understanding, if you want to read/write session state value in HttpHandler then you have to implement

IRequiresSessionState

. If I am wrong then please let me know.

public class Handler : IHttpHandler,IRequiresSessionState 
{
...
