Sort The Rows In A Bindingsource?
Mar 29, 2011I need to sort the rows in a bindingsource. When I sort by a field name, ASC, it works correctly, but when I sort in DESC mode, instead of being the opposite of ASC, it sorts the rows whose fields have the same value in ASC order. For example:
I've got a column with the values A, B, P, P, P and P
ASC: A B P(1) P(2) P(3) P(4)
DESC (as i want it to be): P(4) P(3) P(2) P(1) B A
DESC (as it sorts):P(1) P(2) P(3) P(4) B A
Is there any property in bindingsource which I can use to change this?

Add Rows Inbetween Rows In Gridview Based On Parent And Child Node
Jan 19, 2011I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?
Jul 30, 2010How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

View 1 RepliesVS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?
May 8, 2012I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):

Accessing Specific Rows And Information From The Rows Using VB In An Access DB
Mar 23, 2010Public Shared Function isMatch(ByVal username As String) As Integer
For i As Integer = 0 To table.length - 1
Dim cellValue As String = table.getRow(i).getCell("Alias")
[Code].....
I have the code listed above as a translation from a Java snippet. The problem i have is that in Java, my table was stored as a dataset and as such, the methods were easily identifiable by "getRow" and getCell" using specific numbers and column names. However in VB the information is stored in an MS Access database (which i already have an open connection to, called: "_SalesPerformance_AnalyticsToolDatabaseDataSet12") and as such i do not know the correct way in which to iterate through each row in the database, checking a specific column against an already specified variable and then returning an integer based upon the value of a seperate column in the same row.

Asp.net - SessionID Randomly Changes On Postbacks?
Feb 3, 2011Our solution is built on ASP.NET v1.1 framework. User is presented with login form, so upon providing credentials this information is posted back to the server. Upon postback SessionID changes and our application crashes as some information which is required for processing is stored in the cache and is identified by SessionID string as a part of the name.
This SessionID change happens absolutely randomly and only to some of the clients. Most of the time browser used to view the page and post info is IE8. I cannot reproduce this issue in our test environment, as SessionID is persistent though-out the whole testing process.
I've already checked all solutions, i.e.
Session cache is used on Page_Load to retrieve/store some information, so it's initialized and contains data stored. I've made a Health Monitoring check on Application_End event to capture any possible AppDomain crashes using Reflection and Diagnostics Libraries and retrieving ShutDownMessage from httpruntime object, but that's also not a case. Cookieless attribute of the sessionState in web.config is set to false (using URL to store SessionID is not an option)
All MS security and bug fixes are installed on the server. IIS Server settings are similar to the ones we use in Test Environment.

I can run this 100 times under the exact same conditions and it seems like 40 times it will crash with the following error:
"Cannot access a disposed object. Object name: 'frmImportExport'."
It will either die on

Dim __Delegate As New _Delegate(AddressOf StartProcess)
Me.Invoke(__Delegate)
or
Dim D As New _Delegate(AddressOf SOPERATION)
The form isn't being disposed manually anywhere that I see, and this code is being executed on formload. It's a subform that is to be displayed within a main form.
