(i have used time picker jquery to get time.)

I have a page register.aspx that a user can use to register on my website. Once the registration process is completed, I redirect the user to thankyou.aspx where he will get a code to activate his account.
My problem is this: from the thankyou.aspx page, if the user click the "previous button" on the navigator, he can still have access to the information he had previously submitted and might cause data duplication . I don't want this to happen. I want in that case to redirect him back to thankyou.aspx or another page which will be different than the register.aspx.
My questions are:
1. how can I prevent the user to use the "previous button" on the navigator to avoid data duplication?
2. in case question 1 cannot be done, how can I know in register.aspx that the user comes from thankyou.aspx (which should not normally happen) so that I can redirect him to another page?
My approch was before redirecting to thankyou.aspx, I concatenated session.sessionID and another data to be retrieved on thankyou page. And on thankyou.aspx, I destroy the session after the page was loaded by using Session.Contents.RemoveAll(). And here, nothing happens. The session is still on when using the previous button.

View 2 RepliesI have a web page containing a multipage and 3 pageviews filled with controls... linked to VB server side code.All I want to do, and I imagine it's pretty simple intuitively, is to grab all the controls from one of the 3 pageviews and add it to the multipage.
Now I have 4 pageviews. The 4th one being a copy of either pageview 1, 2 or 3.I looked everywhere and I understand I need to deep copy the PageView and stick it to the Multipage, as I already do for a blank PageView, but I am missing the rest.
I would like to know how to avoid the same operation from being performed twice after some action has been taken on the gridview.
i.e. on clicking a button in gridview, operations in RowCommand get executed. Then on doing a page refresh, the same thing gets done again.
How can we avoid this?
Example: url is [URL]
I click an asp:Button which cause a postback, but now the url comes up:
[URL]
There is nothing special in the button, just id and runat.
This only happens when I start with the "/88" in the starting url?
Why, and how can I prevent the duplication. After the postback I want the url to be the same as when started.

How can I display edit and new buttons without duplication in a detailsview control? This is a question from a past exam paper for 70-562. Part of the question is below:
"The company CIO assigns a task to you. According to his requirement, you must make sure that the users can insert and update content in the DetailsView1 control. Besides this, you have to prevent duplication of the link button controls for the Edit and New operations. At line 3, which code segment
should be inserted?"
I am new to ASP.NET but have had about a year of experience with VB.Net. Currently I am working on a webpage where I can download my inventory list from a GridView control to an excel spreadsheet. The routine is very straight forward however I cannot get it to stop duplication data in the spreadsheet. When I run my routine it inserts the gridview twice in the spreadsheet, the second one immediately to the right of the first table...
[code]....
It renders perfectly on the page by using the following commands:

I have tried a little bit of everything to stop the duplication and am completely stumped.
I populate a DetailsView from an ObjectDataSource that is coded in a class - meaning that the ods Select, Update, Insert and Delete are class methods. The selected record is set to come from a GridView.SelectedValue.
My problem is that when the page loads the code crashes. I am pretty sure I know why: the DetailsView is pulling from a class object and instead of using the existing class object it instansiates a new one which is empty.
Here is the details view code:
[Code]....
Here is the odsDetailsView_1:
[Code]....
As you can see from the code the odsDetailsView gets it's information from a class object "Match". The detailsview is not controlled by any code behind.

i have two radcombobox on my page and i am controling their focus by jquery...also i have some code on their OnClientFocus , therefore focus and blur are so important ...my aspx and jquery code are like this : (without RadComboBox -> OnClientFocus )

it seems that radcombo box can not foreget it's focus and stick with that , therefore when i play with 2 buttons (enter=13 and upper key=38 as you see in the upper code - Jquery) For Changing Their Focus so RadComboBox OnClientFocus does not fire until i click on my page and Click On the RadComboBox Again...These Lines do not work:
1-$('input[id$=RadComboBox1_Input]').blur();
2-$('input[id$=RadComboBox2_Input]').blur();
how can i take focus off from radcombo box i destroy it's highlight?
Can I provide a Combobox that will EITHER let a user type in a value OR let them select from the dropdown? I am trying to create a scenario where a user can attach a value to an object they are editing. When attaching that value, I want them to be able to type in a completely new value or, select from a list of already-existing values.
When I create the combo box, I add a list item that has text like "Type a value or pick from the list"...this has an index of 0. Then I append the databound values to the list.
A combo box seems like the perfect solution since it combines a text box with a drop down list but, I can not figure out how to retrieve the text that has been typed into the combobox once the form is submitted. cmbMyComboBox.text seems to be the obvious way to do it but, that returns an empty string. If I try to get the SelectedItem.Text then, I get "Type a value or pick from the list" instead of whatever text I typed into the combobox, once it was displayed.
Am I trying to do something that the ComboBox is not meant to do? How can I accomplish this?
I have decided to abandon trying to use the combo box. I am trying to use a dropdown menu in one column, and text boxes in all the others. But, I am having a strange problem with that as well. I will post those problems in the appropriate forum. I marked this post as "No Status" because I didn't see any way to delete it.
I'm still struggling with my scenario. I have looked everywhere for a solution and cannot find a solution. I am using C# and ASP.NET and I need to export data to an Excel spreadsheet.
I have a list of applications that contains Application objects. Each Application object has a status ID. When I export these applications to Excel then I need a column with a drop down/combo box in it. In this drop down/combo box should be a list of all the statuses from the database. And then I need the status to be selected to that of the application's status ID.
Another question is also with regards to the above scenario. When the user downloads the Excel document then the user can change the status of each application by selecting a different value in the drop down. I will need to upload this spreadsheet and loop through the rows and get the values of the columns and the value of the selected item in the drop down/combo box. How would you do this? Is this possible?
I may not use COM components, so I tried to go with EPPlus or NPOI (it does not have to be these 2) but it doesn't seem like they support my scenario. How would I be able to achieve my scenario? Once again, it doesn't have to make use of EPPlus and NPOI.
When i select or autosuggest in a combo box , i should be able to get the selected value in a text box in the client side using ajax without a postback.
