Below is my revert subroutine:
Private Sub BindingNavigatorRevertItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorRevertItem.Click
Me.GpheaderBindingSource.CancelEdit()
[Cdoe]....
My problem is Me.gpdetailbindingsource.canceledit() cancels only the current row being edited. I want all rows of my detail be reverted.
I run this, but my row of data is still being deleted.
PreTicketBindingSource.CancelEdit()
Dim datatable_default_view As DataTable = _datatable.DefaultView.ToTable
Dim servicenumber As String = datatable_default_view.Rows.Item(e.RowIndex)("Service Number").ToString
'gets the service number of the selected row[code]....
I've put this code under the DatagridView_CellEndEdit event
The Problem: The 'data_row edited' variable doesn't get initialized when exiting the cell in edit mode using the keyboard (ie: pressing the down/up arrow).If I use the mouse it works as expected. Why is this ?
I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.
View 1 RepliesI think I started out with a misunderstanding of what happens with addnew() and canceledit().
I have a strongly typed datasource in memory.
I call bindingsource.AddNew()
Later I find that the record the user was trying to add already exists, so
bindingsource.CancelEdit()
I have not set any properties other than datasource on the bindingsource.
My assumption was that the CancelEdit() would rollback the blank row added by the AddNew(), but I'm getting some odd errors which lead me to believe this is not true.
Could someone verify that CancelEdit() leaves the new row?
I have a problem with bound controls and a bindingsource. I'm using vb 2008 and .net 2.0.I have a few text boxes bound to columns in the binding source.The backend is a Access database.
I'm using a bindingnavigator to add a new record.The additem event works fine.If the user clicks an icon to cancel edit, the code executes bindingsource.canceledit. This seems to work fine. The row count on the navigator returns to the correct number before the addnew event occurred. However, the bindingsource seems to have an empty record in it. As the bindingsource navigates, it eventually gets to the empty record depending on where it's position was when the addnew event fired.
The error received is an invalidcastexception. This error occurs because the record is repostionedand each time this occurs the code performs calculations using values from the bound controls.But when it navigates to the empty record, the values in the bound controls are null.Is there other code besides canceledit to remove the empty record?

I am using VS 2008, Windows XP R3, and Visual Basic.When I open some forms in the form designer, (In Solution Explorer, right click on the form, then select View Designer) the form always opens as Edited. An Asterisk "*" appears after the form name in the open window tabs. If I open the form to just view the code (In Solution Explorer, right click on the form, then select View Code), the form opens normally. This happens for just some forms.
It always happens for the same forms, and never happens for the other forms. What I am missing in those forms where the designer always thinks the form has been edited?

The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

I 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.
How 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 RepliesI 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):

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.
