VS 2005 - Bindingsource Removecurrent - Difference Delete Or Adding Button
Apr 27, 2011If you have a form with two datagridviews that were dragged on to the form from a datasource that have a parent/child relationship with foreign key constraints. Is there any difference between using the binding navigator Delete button or adding a button to the form and in the Click event put "somebindingsource. RemoveCurrent". Basically what I'm trying to find out is if clicking the navigator Delete button causes "Removecurrent" or does it do something else or something additional.

VS 2008 BindingSource NullValues?
Sep 28, 2010Maybe i'm missing something, but how can i make my application to save the value that i use to replace the null values that exist in the database?Let me explain i have a form with several textboxs to let the user enter/edit some data. At the first time the user opens the form, the are some fields in the database that are null, so i use one of the overloaded versions of the control.databindings.add(), and set default values for those fields.
My problem's when the user clicks save without changing any of the default values, i can't detect any changes to the datatable, so the update method doesn't update anything.

VS 2008 Getting Filtered Data Using With A BindingSource?
Oct 17, 2009I'm using a bindingsource to bind a dataset to a datagridview. Normally I would use a dataview to sort and filter the data, but since a bindingsource can also do this, I figured I would not need a dataview anymore. But I'm not sure how to get certain data from the filtered source. I know I can get it from the datagridview, but I'm not loading the entire dataset into the datagridview. I guess I could and then just make the columns I don't need be invisible. Or I could go ahead and use a dataview also, but that seems redundant. I was wondering if there is an equivalent to this code to get a specific item from a dataview, but pulling it from the bindingsource:
tbCode.Text = dv.Item(m_recno).Item("CodeNo")
As long as I'm not filtering the data, I can get it from the dataset, but when it's filtered, the indexes won't match.

VS 2008 - BindingSource Position Changed Event
May 5, 2009I datagridview and I populate it using a bindingsource. I have the following code in the bindingsources PositionChanged event and it works as I want it to except when I filter the bindingsource.
Private Sub ProductBindingSource_PositionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProductBindingSource.PositionChanged
If (Me.ProductBindingSource.Current IsNot Nothing) Then
Dim dr As DataRow = CType(Me.ProductBindingSource.Current, DataRowView).Row
Dim ProductId As Long = CLng(dr.Item(2).ToString)
Dim ResultId As Integer = CInt(dr.Item(0).ToString)
GetReport2(ProductId, ResultId)
End If
End Sub
The scenario is when I click on a row in my datagridview the bindingsources positionchanged event fires and I load a crystal report. Problem is when I filter the bindingsource, even though the first item in the grid is now different the incorrect report is displayed because the bindingsources position hasn't changed.
VS 2008 Datatable - Datagridview Using A Bindingsource And Dataadapter

Then for each day I tick I have to save to my pupil_job_day table. I will save the peoleid,their accountid and the date. please help me

View 4 RepliesVS 2008 Bindingsource Currentchanged Event - Refresh The Data By Clicking Row
Feb 19, 2010I have added a handler in my code for the bindingsource currentchanged event: I have populated a datagridview. AddHandler PeopleBindingSource.CurrentChanged, AddressOf ChangeHandler then on the ChangeHandler Sub I populate an HTML report. However I don't think this is the best event to handle this. I have to datepickers on my forma as well. So say I click on a row in my dgv, that persons report loads. Then I change the start date on my datepicker,
Now i want to click on that row again to refresh the data, but since the currentchanged event doesn't fire the data won't refresh. I have to click on another row then click on the row I want to view in order for the event to fire. which event is best to do this?

The issue is in the last line.
