Web Forms :: Wrong Data Getting Inserted Into Printed Report?
Jan 26, 2011
So I have an ASPX page. the only thing i am doing is creating a XPS/PDF report to be sent to a customer. everything works well but now we have a bunch of customers and people are hitting the page quite a bit and we got a complaint about wrong data being in the report. i can reproduce this when i hammer the aspx page with like 10 reports at once. I will see the 2nd persons data in the first persons report randomly. is there something going on with cacheing or is it using the same instance of the page when the 2nd request comes in while the first report is getting generated?

I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?

I have a very weird thing happening. I have two databases that have exactly the same tables but different database names on the same virtual machine, but in different instances of SQL Server. For some reason, when using one of them, it will save to the other. In debug, looking at my connection string..I have verified that it is correct, yet when I allow the save, I look in the table and it isn't there, it is in the other database that is in a table with a completely different name and in a different instance of SQL Server.

i m using Parameters .AddWithValue("@ ", .text) method t insert data from textbox to my data base. i m using SQL data base. primary key is auto incremented. problem is that when i click on submit button to add the data in data base, all the code works fine, and my data get inserted in database table. but then if i click on refresh page, same data get inserted again in the table. and if i click twice or thrice on refresh button data get inserted again and again. i solved this problem by redirecting the page to same page. but then i lost my view state of data. i want to keep the view state and restrict this insertion of data on refreshin. how can i solve this problem by keeping the view state.

I'm coding with VB.NET and have a webform that includes gridview. The gridview captures data via a db view. Also the view includes all the parameters of the tables.
The problem is: when start program, there is only 2 rows seen on gridview. then i can insert something successfully. And when i checked from db i can see the new data. But in my form, newly inserted data doesn't seen. Even i restart the whole program, gridview always shows only 2 entries.

I have a SQL 2005 database table with a column that has a datatype of nvarchar(255). It holds URLs.I created a FormView to edit records in the SQL table. The value for this column gets put in a TextBox in the FormView.When trying to edit the record, any text placed in the textbox gets truncated at 50 charactersI checked the TableAdapter in my dataset, and in the properties for that column, it has "255" for MaxLength.

I have gridview, and in this gridview, I insert a new row dynamically depending upon a value from the database all the way down the table. Even though this is all working well, I need to access a number of controls that I added to the inserted row. Namely, a checkbox and label. When I try to access these controls, I am getting an error message - object not set to reference. Then I tried saying "Gridview1.Rows[rowIndexVal].Cells[1].Text = myTextVal", but what this does is to insert the value on a different row.
Therefore, I have two problems, which I am really desparate to try and solve:How do I access the correct row and control that I have added to my inserted row, andBecause I have a checkbox control on my inserted row, which has an event associated with it, how do I get the selected row the user clicked. When I try doing this using FindControl, I always get a row index of zero.I am using Table object and TableCell to add a new row dynamically to the gridview, and then using ColumnSpan to make it fit the number of columns in the gridview.

I created an AR statement using crystal report. The main report gets customer info and use customer ID and from and to dates to link to three sub reports. The three subreports are (1) opening balance, (2) list of transactions and (3) aging summary. When I previewed it from VS2005 design mode, everything shown pecfectly however when I run it from VB, only the list of transactions shown and the other two subrreports only showed labels but no data. In addition, I can send the report to printer and no PDF can be generated.

I have a datasource:
[Code]....
I have a detailsView bounded by some other datasource. There is a dropdown in detailsview which is bounded by sqldatasource named "sdsNature" . Here is the templatefield for dropdown:
[Code]....
I want to show FNature instead of FNatureID in the selected mode as Label and in Edit mode as dropdown. When I am running this project, in Select mode it is showing FNatureID instead of FNature and if I click to Edit the record it is displaying following error:
'lstNature' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value Do I have to give some If else condition that if FNatureID is .... then dropdown should display FNature.... If yes then what should be the code?

I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:
<td class="style4">
<asp:TextBox ID="urlTextBox" runat="server" Text='<%# Bind("url") %>' CausesValidation="True" Width="200px" />
</td>
I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.

I am using a Listview with InsertItemTemplate bound to a LinqDataSource with a child table in the ORM datacontext. This table has a relationship with a parent table in the OR/M datacontext. The record is to be inserted in the child Table. The parent table is bound to dropDownList in the InsertItemTemplate to provide a user friendly name. Using the ListView ItemInserted event in debug, I can follow the execution and no errors occur BUT no record is inserted. I confirm this by a showing all Table Data in the SQL Mgmnt Studio. The child to parent table seems to be causing the problem because when I delete the relationship in the OR/M .dbml , I am ABLE to insert records. I am using Scott Mitchells' Using ASP.net 3.5 ListView with Data Pager controls: Inserting Data as a model. I can provide code if required, but what is going on with the deleting of the relationship between child and Parent.

I have a report with some opening text, a table, and some closing text. The number of rows in the table can vary. When the report is exported to Excel or printed, the opening text is printed, then a pagebreak is inserted and the table starts on the second page. I want the everything to be continous with any pagebreaks occuring in the middle of the table.
I've tried modifying the body and page size. I've tried dragging the controls to the left and making them smaller. how to stop the unwanted pagebreaks from occuring?

I have a page with a gridview. It has a select command and an edit command which are both SPs. I added a standard "Edit, Update, Cancel" CommandField to the gridview so that I can edit. The edit and update are working fine. However, I have found that if the underlying data changes after I have loaded the page and before I hit "Edit", and this change causes the row I'm going to edit to be in a different row than before, the gridview will open the wrong row for editing.
For example, say the gridview is sorted by the a field called ID, and currently there are rows in the DB with ID of 2,4,6 and 8. I load the page and see those 4 records. While I'm looking, someone adds a record with ID of 1. When I click Edit on the row with ID = 4, I will actually end up editing the record with ID 2. Basically, i'm clicking on Edit in the second row, and I end up editing the record in the 2nd row, but the 2nd row is now a different record than before.
It seems like there HAS to be a way to fix this, otherwise editing in the gridview seems exceptionally dangerous. Is there any easy way to handle this, to make sure the user is editing the row they think they are?

I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.

This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.

after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back

I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.
