Web Forms :: Page Refresh Creating Duplicate Entries In The Table?
Mar 25, 2010
We have developed the Application using Visual Studio 2008, After publish we got the issue like After Submitting the Form the user can able to Move Backward and do the Refresh. This will again triggers the Submit Post Back and the Duplicate Record Created As Well.
This is happening for all the Web Forms. How to Avoid this ? I need a Generic Solution where i can implement that logic in Base Page then the rest of the Pages this functionality will be covered by default.
Moreover, Before Refresh We should also intimate user "Do you Want to Post the Same Data Again ?", if the user clicks Yes then it can allow the same record can be posted again.
How to do this ?? But i cannot disable the Browser Features like back, forward and Others. I have found many solutions in various web sites but it is also happening for the Validation Part Also...
I'm using SqlMembershipProvider and SqlRoleProvider for user management.
Users are created by
Dim MCS As System.Web.Security.MembershipCreateStatus Dim NewUser As MembershipUser = Membership.CreateUser(TB_UserName.Text, TB_Pw.Text, TB_Email.Text, TB_SecQuestion.Text, TB_SecAnswer.Text, False, MCS) later, after email confirmation, I take the user into a specified role Dim myUser As System.Web.Security.MembershipUser = Nothing myUser = Membership.GetUser(New Guid(Request("RegID")))Catch If myUser IsNot Nothing Then myUser.Comment += " approved " Membership.UpdateUser(myUser) Roles.AddUserToRole(myUser.UserName, "role") End if
After this I have two entries with the same UserName in aspnet_Users table, but with different UserId's. One UserId is referenced in aspnet_Membership table and the other in the aspnet_UsersInRoles table.
I Am working on payment gateway integration, i am storing whole information about the transaction on page load event. so when i press refresh button then Duplicate data is again inserting in database So i want to stop this.
I want to do like
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { // Here I Am Using My Function For Insert Or Update Database } }
I am using the built in database with the tables (i.e. membership, users, etc...). I created my own table (relationships), but when I try to create a row that uses the same email address it says "cannot create duplicate entries". I am not allowing duplicate email addresses in the membership table. That did not work because I couldn't convert System.Guid to long. So, I decided to do it by email address. I changed idRequester to requesteremail and the same for receiver. However, when I try another record with the same email address in either field, it does not accept it.
I have a receipt page for my clients that will display their info and they will get notify by an email message. Here is the problem: when user hit refresh button from a brownser, it will send duplicate email message to the user.
This is what i have:
protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) SendEmail() } protected void SendEmail() { //here is my function for email }
I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.
I want to show just a 8 entries pro time, and above the table make some kind of navigation (like 1 2 3 4 5 ..) and if i need to see next 8 entries I#m clicking on the number 2, i see them. I dont know how can i do all this.
i working with mvc, and i want too that this solution is dynamic, that by more entries automaticly will have longer navigation 56 enties = (1 2 3 4 5 6 7).
An option to add a range of computers based on tag numbers, for instance, user input 800101 and 800110 would add computers SYS800101, SYS800102, SYS800103, SYS 800104, SYS800105, SYS800106, SYS800107, SYS800108, SYS800109, and SYS800110. Currently the app adds a single computer at a time.
Here I am using ASP.NET using C# and my backend in active directory.
I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt

Is it possible to setup the CreateUserWizard to check for a duplicate entry in the aspnet_profile table (for a custom field) before the new user is created? For example, if I added a phone number field and wanted to make sure nobody else could create an account using that same phone number if a user already has an account with that phone number in the aspnet_Profile table's PropertyValuesString row?
I have an ASP:Table that has one row in by default. I would like to give the user the ability to, by clicking a button, add the same row again to enable more data entry. The end result being that I can commit the data in the rows to a SQL database.
