View 2 RepliesI have a simple web service, in it i have a static class which has a static collection to remember alive tokens.
I just want to make sure that the token collection lives until the next iisreset or the application pool recycles.
And what is the difference between remembering states in Application bag and static class?
I am developing a custom control that needs it's viewstate to be loaded on init. Can I antecipate the view state loading at any time?

View 2 Replieswhere is session state, application state in page life cycle?
View 2 RepliesI am writing a web application that takes in session variables from the user and when the user comes back to the page the form elements are automatically filled with the users entery. So I tried using the page_load event to check to see if the session object was equal to null. But then when I rerun the application the form elements are filled in with the previous entery. Does this mean that if a user logs into the system and has a session withing the lifetime of a previous session that the form elements will be filled in with the previous data?

I have a listview control, in it each item will have a checklist eg - Pass / Fail which will then have a label displaying the selected value. I also have datapager wired up to the listview.
When i toggle between the datapages and toggle back, any result previously submitted will be wiped.
I am thinking i should be using session state to temporarily store then info, and then once the session is finished use a submit button to send all values and ids into an xml.
1. Is this the right way of approaching the situation?
2. How would i specify session state for listview items, eg would i angle it through a itemdatabound event or the application itself?
1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).
View 4 RepliesI'm using Visual Studio 2008, and when I select/highlight something in design view and switch to source view it does not highlight and scroll to the selected item. This makes it really hard to change stuff in source view, and it's very inconvenient at worst
View 2 RepliesI am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.

View 2 RepliesI know the basic of view state. But I dont understand the functionality of view state at a control. For example, a texbox has a property view state. what is the purpose ? what it wiil act for true or false value.
View 3 RepliesI have two radio button list:
*1* report views -- 4 options -- NOT in updatepanel
*2* pagination views -- 2 options -- IS in updatepanel
The situation goes as follows: Refresh WORKS in default setting but when I select *2* radio button options and refresh the page renders the state that the (1) was entered in.
Example: () are the radio buttons
Report Viewing: () (x) () () Pagination View: (x) () REFRESH works!
Report Viewing: () (x) () () Pagination View: () (x) REFRESH fails to display Report Viewing: () (x) () () Pagination View: (x) ()
Report Viewing: () (x) () () Pagination View: (x) () REFRESH works!
OR: () are the radio buttons
Report Viewing: () () (x) () Pagination View: () (x) REFRESH works
Report Viewing: () () (x) () Pagination View: (x) () REFRESH fails to display Report Viewing: () (x) () () Pagination View: () (x)
Report Viewing: () () (x) () Pagination View: () (x) REFRESH works
I am using the session variable to hold the Pagination Viewing option but during page states, I've noticed that when a 2nd option is selected of *2* radio buttons (doesn't matter of 1st or 2nd option was initially selected) that during debugging mode the step over corrects the issue but not the right table viewing. Upon entering Page_Init selection selection index of radio button list returns to 1st option.

View 9 RepliesI have a grid view with a nested text box in it.I would like to turn view state off but the fact of the matter is when data is posted,the text boxes inside the gridview aren't available (there are no rows in the gridview on postback). Control's information is not stored in the View State (for things like selected value and .text etc.):Control state,introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state.However,control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.

I am trying to what i think is an easy task, but so far i have came up empty.
What i want to do is take a repeating table on a form i have and submit the employee IDs to a database using a web service.
I know how to submit them one by one, but i am thinking there is an easier way to do this instead of send the value to the web service, submit thee data, and then go till the last record.
I am currently using this:
<WebMethod(Description:="sends employee id to database")> _
Public Function SendMultiple(ByVal strEmployeeID as string) As String
Dim sqlCon As New SqlConnection()
Dim sqlCmd As New SqlCommand()
sqlCon.ConnectionString = "connection string information"
If sqlCon.State = ConnectionState.Closed Then
sqlCon.Open()
End If
sqlCmd.CommandText = "spInsertMultiple"
sqlCmd.Connection = sqlCon
sqlCmd.CommandType = CommandType.StoredProcedure
Dim Parameter0 As SqlParameter = New SqlParameter("@EmployeeID", strEmployeeID)
Parameter0.Direction = ParameterDirection.Input
sqlCmd.Parameters.Add(Parameter0)
Dim dr As SqlDataReader
dr = sqlCmd.ExecuteScalar
Dim strReturnedValue As String = "hello"
Return strReturnedValue
End Function
In the user form, the user has a chekboxList, and he can select more than one item.
how can I store those selected items in database, and how then I can retrieve them.
"
Is it true to make a separate column for each item, and then if selected, then that cloumn will have "1" and "0" for non selected.
"
Only that idea occurred to my mind, and I think that I can find better it.
