One To Many / Datagridview / Table Manager?
Dec 22, 2010
Made what I think was a tactical error by using lots of 3rd party controls that made it easy to get stuff going but resulted in carrying a lot of baggage with my apps. Now it is finally time to switch to VB.Net and I want to avoid 3rd party controls as much as possible.
The database is MS Access. Master table called GroupName, key GroupID, string GroupName. Child table is GroupCustomer, key GroupID+CustomerID. Two datagridviews, GroupName on top, CustomerGroup on bottom. I've studied the one to many videos and howto's and it is easy and works like a champ. Fill the tables, sort, filter, add, update, delete, all is well.
Top grid
GroupID1 GroupName1
GroupID2 GroupName2
and so on.....
[code]....
However, adding a third table is where I get into trouble. In the bottom grid I want to link customerID to the Customer table to pick up Name, address, city, state & zip for display purposes. I've modified the table adapter to create a select query returning the lookup data with the groupID and customerID. It displays nicely on the Fill but doesn't automatically refresh the customer lookup fields when I add or change a customerID and I can't seem to update new records or deletes. The only table in my query that I want to update is the GroupCustomer table but the query is not updateable.I've been trying to figure this out, read articles, learn, step back and think but am still stuck. how to use the controls that come with VS2010.

I am trying to create a smart client (multi table manager). I didn't want to make it a MDI app, so I used a TabControl to host each table UI. I am having problems with the BindingNavigator control. When I drag the table grid from the DataSources to the top tabpage, the designer adds all the needed controls. However, on the other tabpages it doesn't add the BindingNavegator. So, is this the proper behavior or am I doing something I am not supposed to do? What would be the best way on doing this? Do I need to make it a MDI app.?

My Application ( Vb.Net) is to scan Access DB forms and find out the Activx control if present and it works fine. But my problem is.In some DBs we have tables with mapping path to specific locations (Table Property->Linked Table Manager) and when we relocate these DBs then we need to change the path manually otherwise it will show a message to re-link ( Access DB message) while opening the DB. And I am facing same problem while scanning through my Tool as well and my process stops, continue only by manual intervention.
Do I capture the massage event and send some user specific message to user in the Log file or Report and continue scanning further?

I have a form which has a dataset and a datagridview. The form is built with 3 textboxes (TxtPracticename, TxtRegion, TxtPostcode) and the datagridview (Dgvcontacts) has 4 columns (address1, address2, address3, town). So when the form loads the textboxes and columns are populated by the following;
Code:
Me.GP27TableAdapter.Fill(Me.BinleyDBDataSet.GP27)

I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView.So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs .manager and ComboBox to set the active AnnounceURL.

I have a function that will allow me to edit the manager property of a user here:
Public Shared Sub SetManagerProperty(ByVal de As DirectoryEntry, ByVal pName As String, ByVal pValue As String)
'First make sure the property value isnt "nothing"
[Code]....
But what if the manager is not in the Company OU? How can I edit this to search for him in the entire domain?

Let's say, I have something like a table in the WebBrowser component, it's not actually a table, because the data organized in flash, but, it's organized like a table, it has like rows and columns. You can see more in the attached file. Can I transform this text organized as table into DataGridView or some another tool that serves as table. like_a_table.JPG

My application must display some data in Datagridview (status of COM ports communication) and i Used .mdb databases before for faster search and Datagridview update. How i understand Datagridview is importing data from DataTable and data in DataTable is imported from .mdb file, so i decided to make shortcut - stop to using .mdb file (data must be erased every time application start and it is useless make .mdb file and erase it every time, becouse it is increasing even when drop is used) and using only DataTable..
I want to row in Datagridview change it color to red when it's Collumn(6).text countains %error% string..
When Error in COM port is starting, i can fast find row in DataTable for that port and write information that Error accured for that port and DataGridview automatically updates:
Dim RRow as () DataRow
RRow = ds.Select("Port = 'COM3')
RRow(0).Item(6) = "Error Opening COM3"

I have a DataGridView table that I allow the user to enter data into. I have a button to add a row. This works OK but how can I select that row after the button has been clicked. The reason for this is so the user will not have to scroll to the bottom of the list the enter data into the new row.

I have a DataSet with many tables and a single DataGridView. I need to select a value from a combobox and then pressing aButton to show the selected table to the DataGridView. For example if I select from combobox "Selection1" I would like to show to the Datagridview the contents of the table called Selection1. I paste the event that I thought might work but doesnt show a think: Private Sub aButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles aButton.Click

I have set up at DataGridView "cdgvExp" for data entry. cdgvExp.Datasource = ExpTab. The datagridview can accept new rows according to how many entries there are. I will then use the data in ExpTab. The Fourth colum is called "Lot" and is a combobox in the datagridview. The goal is to have the Combobox in the fourth column have the datasource be LotTab which is populated according to other choices in the form. I am hunting for something that would work like an independant combobox like cbLots.datasource = LotsTab
How do I dynamically set the Datasource and Datamember of a combobox that is already set up in a datagridview?

What i am trying to do is to have a fixed initial row heigh of 60. Then the user is to put Data into the empty fields. When it user clicks the add button it will loop until it reaches an empty record and then it will insert the data into a SQL Database. Its simular to my code below but with a DataGrid. Also, this DataGrid is located on a ControlTab. The code below is just to show the logic of what i am trying to do.
Private Sub btnInkjetGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInkjetGenerateTicket.Click
'Description: This INSERTS and Generates ticket from the InkjetTab fields

I am facing a "weird" problem with the DataGridView. In fact, I have a function, that loads each table of an xml file into a datagridview (27 tables all with same structure except one called Listes). In the datagridview I have a combobox column to select "type" (it's the 3rd Column, so it's index is 2 normally). The problem is that when I call the function loaddata for the first time, all work perfectly ! If I call it for a second time, to reload the data, I get an error of cast! I verified and it seems that first time I call the function the column that contains the combobox is column(2), but when I run it again automatically the indexes of the columns are changing and am getting the error, because the column that contains the combobox is becoming column (3) and that explains the cast error because the column'(2) is not anymore the combobox so the cast will fail ! What I can't understand is why it's reordering that way my columns automatically ?
Here is the code:
vb.net
Sub LoadData(Path As String )
Dim oData As DataSet
oData = New DataSet
oData.ReadXml(Path)
Dim i As Integer
Dim MaGrille As DataGridView
