Jan 6, 2010

- put datagrids modified information in new dataset
- set report's databinding source to new dataset
- generate report...

Referring To A Previously Existing DataSet?

Jul 21, 2011

I'm working on a very basic VB.net frontend for an Access database and have stumbled upon a problem.

Dim ds As DataSet
MaxRows = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows.Count
i = 0
Private Sub Navigate()
txtCourseReference.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(1)
txtCourseName.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(2)
End Sub

I get the error that Object Reference is not set to an instance of an Object. I think this is because I haven't defined the DataSet as "Course_assignmentsDataSet"- the one I want to use- but I'm not sure how to do this.

Get The Filtered Rows Into A Dataset Or Datatable In A Datagridview Bounded To A Bindingsource?

Nov 22, 2009

I have a datagridview bounded to a bindingsource (that is, in turn, bounded to a dataset that is the data origin of the project) and a bindingnavigator to a Access table, all of this done with the visual designer of Visual Basic .net 2005. I want to print in a crystal report the rows shown in the datagridview after filtered using the .filter property of the datagridview. But, to achieve this, I need to get the filtered rows in a dataset, and I havenīt got this in any way. If I pass to the crystal report the main dataset origin of the project, it will print all the rows, not only the filtered rows. I would have figured out that there would be a .getfilteredrows or something like that in the bindingsource object, but there isnīt. I managed to get this manually, through a loop, but I canīt believe it is the solution experts use.

Insert Changed Data From One DataTable Into A Database Table In A Different DataSet

Oct 26, 2011

I want to track changes in an application. So I've made a copy of the main table in that application, and am accessing both tables in the application using two separate datasets.

My plan was to use the HasChanges method of the main DataSet to get changed rows and then insert those into the copy table. When I run the code I get an error:

A first chance exception of type 'System.InvalidCastException' occurred in MyApp.exe

Unable to cast object of type 'MainDataTable' to type 'MainAuditDataTable'.

Here's the code:

If Me.DataSet3.HasChanges Then
' 'look for each row that has changes, not new rows
' 'insert that row into the auditing table

Export XML Data From Multiple DataGridView And Import Again Later?

Apr 1, 2009

I have several DataGridView controls populated with data. I want the ability to export all the data from these populated controls to 1 XML file. In effect the controls are populated after my project runs. The user will be given the option to export the data.

I then in turn want the ability to import this same data back to these empty controls at a later point in time. I would run my project in a different mode which would display the empty controls. The user would be given the ability to uploaded the XML file and repopulate the controls.

IDE :: Dataset Code Behind Datatable.ColumnChanging Event Firing / But Dataset.HasChanges Property Not True

Jan 28, 2010

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
