Bind DataGridView With 2 Tables?
Mar 8, 2010
I have a datagridview who's datasource is a BindingSource. The problem that I need to resolve is that the DGV has 6 columns, 5 of which come from the same database table, while the other column comes from another database table. Is there anyway of configuring the BindingSource that will make it contain all 6 columns?
The same grid in Part 1 works in the way that when a user selects a row, textboxes and comboboxes are populated with the DGV Row of data in order for the data to be modified. When the user makes any changes, this modified data needs to update the DGV row or BindingSource. How do I associate the changed values back to the BindingSource or the DGV?

I was wondering if there is any way to bind TWO different database tables to ONE textbox in VB? I've spent the whole day going through tutorials and different webpages and I've found nothing at all on this...
Well let me try to explain what I want to do exactly: basically I have multiple buttons on 'Form 1' and a textbox on 'Form 2' asking the user to insert a value which will then go to an Access database. But here is where it gets tricky for me: IF the user presses Button 1, the Value inserted on Form 2 will go to a field in the database whereas if the user presses Button 2 to open Form 2, then the value will go to somewhere else and so on.
This would be easy to do if I was to create multiple forms or multiple textboxes, 1 for each button but what I really need is 1 form/1 textbox that would work for all of them... [URL]

I am developing a Windows Form Application against a SQL Server relational database. An example of the database schema is:
TableA
------------------
PK A_ID uniqueidentifier
A_NAME varchar(254)
[code]....
In the form I have a ComboBox (cboA_ID) to select the TableA record (DataSource = TableA, DisplayMember = A_NAME, ValueMember = A_ID) and a TabControl where controls on each tab are bound to fields in either TableB or TableC.My question is, is it possible to bind cboA_ID to TableB.A_ID and TableC.A_ID?This is my first database application so if there is a better way to do this I'm all ears. I have set everything up using the wizards in Visual Studio 2010, so I'm still not 100% familiar with what all the various TableAdapters and DataSets do.

I think my subject sums up what I am interested in knowing. I am looking to create a chart where Series1 is from Table1, Series2 is from Table2 in the given Dataset. My code below doesn't throw any errors, but it appears to be grabbing the data for each series from the first table.
Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Public Sub New(ByVal ChartData As DataSet)

I have the following:
a table of addresses and a bindingsource for the table
a enum list of address type: 0 = "Mailing", 1 = "Physical", 2 = "Shipping" etc...
I would like to bind the datasource of the combobox to the enum so it displays "Mailing", "Physical" etc. Then I would like to change the bindingsource position of the address table based on the user selection of the combobox.
Here is what I have so far:
cbxAddressName.DataSource = New BindingSource(ApplicationEnums.GetEnumList(GetType(ApplicationEnums.CompanyAddressType)), Nothing)

I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding

I want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

How can we databind a datagridview to some of the My.Settings (user scoped) properties so the user can edit the values? This must be to a datagridview. I know we can bind to My.Settings in a form with textboxes and so on, but in this case we just want it as list of editable strings in a datagridview.
Of course some My.Settings entries can have different datatypes which complicates matters but generally we're only working with strings and booleans. Also, let's assume the user understands that he must enter the string "true" to set a boolean to true. No checkbox column needed. Here's what we are using (and it works), just looking for a better, leaner way: [Code]

I have bind the DataGridview with DB. To add the data from textboxes to DataGrid, I use the foll. code-
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Try
Dim row0 As String() = {TextBox1.Text, TextBox2.Text, TextBox3.Text}

Error is coming: Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound. there is no any way to add data to the Gridview if we bound it to the Database.

I have a Datagridview with a bound datatable in it. Then I add a check box column to it.
When I click the headder of the DGV, it sorts the bound columns, and clears all checked checkboxes in the checkbox column.
How do I bind the checkboxcolumn to the rest of the table?

I have combobox in a form. The combobox is bound to a table and displays the list of values as expected. What I want to do is also bind the combox to another field in a different table similar to the way the datagridview with combobox works. That is the dgv is bound to the combobox column but the dgv's bound value sets/reflects the value selected by the combobox. I can't figure out if this is possible with a standalone combobox.

know it is possible to have bounded and unbounded columns in a datagridview.Is it also possible to have bounded and unbounded rows?I knows its unorthodox, but I want to have two rows in my datagrid per item in my object list One row is bounded to the properties of each item; below that I want an unboundedrow of checkboxes for each property But since when binding the datagridview sets the rowcount equal to the list count, I'm not sure its possible.

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'd like to partition my search results (which is in a DataTable) into groups of say 100 so the user navigates through them a chunk at a time.I thought I could bind an array of DataRows to a DataGridView as the DataSource but it just does not work. This is the code I tried
DataGridView.DataSource = (From r In DataTable.Rows Skip 200 Take 100).ToArray()
I'd like to stay away using the DataGridView's VirtualMode.
