VS 2008 Datatable - Datagridview Using A Bindingsource And Dataadapter

Dec 8, 2009

I populate a datagridview using a bindingsource and dataadapter. So I join 3 tables in the view to get the data i need.

so I have my view as a child table in my dataset. and a table called classes which is the parent table. So when I select a Class(class 1A for example), my datagridview displays the pupils in that class.

Now i need to add another relationship in the dataset. so when I select a day in a monthcalendar, I need to add 5 checkbox columns for each day to my datagridview. Should I add these 5 columns to my datatable? i'm not sure what the best way is.

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

.net - Disposing BindingSource Breaks DataGridView DataSource

Dec 13, 2011

Brief : I have code which works if I don't dispose of the BindingSource after it has been assigned to DataGridView.DataSource but breaks if I do dispose it - why? Do I need to worry about disposing this?

[Code]...

So, what is going on here? When I set DataGridView1.DataSource = Bds does it just do this as a reference? How does Bds get disposed once the procedure exits? Does garbage collection pick it up if I assign something else to DataGridView1.DataSource? Do I need to worry about this?

DataGridView BindingSource And Structure Array Not Updating?

Jun 19, 2012

I'm having some issues and it's all explained in some simplified code I have a structure

Public Structure myStruct
Public Property name As String
Public Property span As Double
Public Property offs As Double
End Structure

Which is instantiated in a Singleton object as follow

Public myValues(10) As myStruct

Then on a form, I'm using the structure as the DataSource for a SourceBinder and the binder as DataSource for a DataGridView.On loading the form, I get all the values into the binder

For i As Integer = 0 To 9
binder.Add(singleton.getRef.myValues(i))
Next i

All the values are shown on the grid.User is supposed to be able to change the values, which should reflect on myValues but no matter, what code I put on CellValueChanged or CurrentChanged. I can't make it reflect the changes. Using breakbpoints on those events, I noticed that grid.row().cell().values and binder.current never changes.I tried also placing a button and directly changing myValues and reseting the binder binder.ResetBindings(False) and nothing happens.As far as I saw all ReadOnly properties are set to false.I've also tried setting VirtualMode to true on the grid and catching CellValuePushed and CellValueNeeded events but those are never called.

DB/Reporting :: DataGridView BindingSource.Filter Changes Causes Dataerrors

Oct 28, 2008

I have a DataGridView that is bound to a datatable. I also have a combo box with sorting items in it. When the user selects a new item in the combo box, the DataBindingSource.filter is changed accordingly.

For the cell and row validation on the DataGridView, I set the row error text accordingly as opposed to displaying a message box.

Occasionally, when switching between items in the combo box, the datagridview gets filled with a bunch of empty rows that all have error messages. It seems it is validating the rows that existed from the previously selected filter against the new filter.

See attached image. I hope I am making myself clear.

Getting BindingSource And DataGridView To Work In A Seperate Class?

Feb 19, 2010

Basically I try to get a DataGridView and a BindingSource working inside a class. I define them by:

Dim TempDGV3 As DataGridView = New DataGridView
Dim TestBinding As BindingSource = New BindingSource

When I manually add columns to the DataGridView, it works perfectly, but when I set it's DataSource to a bindingsource from a base class, it doesn't load data and keeps throwing 'object does not exist' errors. The bindingsource mentioned here did, however, work on other DataGridViews that are defined in the base class (and implemented in the form to which the base class belongs)

Same for the BindingSource(not the above mentioned, but the one I try to create inside the class in the beginning of this post). I try to use it in the following way:

TestBinding.DataSource = TempDGV3
TestBinding.Filter = filterString()
SourceDataGridView.DataSource = TestBinding

But the BindingSource keeps returning 'Nothing' for it's datasource and basically doesn't work. However, the SourceDataGridView mentioned here gets filled with 63 columns with "AllowUserToAddRows" and other properties when the columns names are asked.

So my question is: how do I get the BindingSource and the DataGridView to work in this class? I'm getting the feeling I'm missing out on something very obviously here. If that's not the case, I can report back with more code?

VS 2005 Update A Datagridview From A Bindingsource - Filter

I'm having problems with bindingsource. I have a proc used to update a datagridview from a bindingsource. When I run the debugger, the datatable appears to be populated rowcount is 2206 and 7 columns. When the bindingsource.datasource is set, everything looks good. The filter appears to be ok, however, when the datagridview is set to the bindingsource, it's not working. I have it in a try/catch block and an error isn't being raised. When I reference the columns to size them, an error is raised. Below is the snippet of

.net - DataGridView.SelectionChanged Event Firing When BindingSource.SuspendBindings() Turned On?

Jul 28, 2011

In the following sample, I create a collection of objects and bind them to a DataGridView. When the button is clicked, I .SuspendBinding, then remove all the records, then .ResumeBinding. The DataGridView1_SelectionChanged event is fired when I remove { m_dataSource.RemoveAt(pos) } the selected row of the Grid. Why is this? I would think that .SuspendBinding() would stop any events from firing through to the grid. If not, what is the point of .SuspendBinding()?

.net - Filtering DataGridview Using DataSet -> BindingSource, Extra Columns Later Added?

Apr 29, 2011

For a WinForms VB.Net application, I use the Bindingsource's filtering capacity to filter data, which is seen in a DataGridview. The BindingSource is from a DataSet, created using the Designer, and the data comes from a Access DB, using JetEngine and .Net 3.5. So basically:

Datagridview.Datasource = xxBindingSource
xxBindingsource.Filter = "[extended filter string with multiple columns]"

This filtering works fine, however, now I included some extra columns in the DataGridView, which I'd like to filter on, too. Of course, when I feed the manually added columns to the Filter of the BindingSource, this doesn't work out.I've done some research, and was not able to find any way to use the BindingSource's filtering syntax on the DataGridview. I'd like to use this syntax though, as I designed quite a nice UserControl and class around it, to provide smooth, fast and simple filtering capabilities.

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.
