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 form(EmailContacts) which contains a datagridview and a button to add the data to a textbox of another form. Everything is working fine and i can display data from the database on the datagridview properly. The problem is how do i add a 'Select All' feature such that when the user clicked once on the 'Select All' checkbox, all the checkboxes of the columns are selected?
These are my codes for the form:-
Public Class EmailContacts
Dim xs As String

I am a student working on a project for my company. I work using Microsoft Visual Studio 2005. Language is vb.net. I also work using windows application.
I have a form(EmailContacts.vb) which contains a datagridview and a button(btnAdd) to add the data to a textbox of another form. My datagridview consist of 3 columns; CustName, Email and Selection. Selection column being the column with all the checkboxes. Everything is working fine and i can display data from the database on the datagridview properly.
The problem is how do i add a 'Select All' feature such that when the user clicked once on the 'Select All' checkbox, all the checkboxes in the 'Selection' column are selected?

I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.
I'm a bit of a noob at this and finding that all my research that's led me to wanting to do things right for data integrity are making it a bit more complicated on the front end.
Presently I have a Form in which I have two DataGridViews that I'm populating, each with it's respective stored procedure.
What the form is for is for linking rows from the one DataGridView (I'll call it DGV1) to a different one in the other DataGridView (DGV2).
Now to facilitate the ease of doing this for the user I want to both have the dgvs fully populated so that if the user wants they can just slide on through and manually select the rows in each they want and then there'll be a button to select which I'm planning to then use another stored procedure to then insert this connection between these two items into the database.
Another thing to facilitate this is a search bar. I want them to be able to type in something and have the datagridviews both navigate to where their selection is as well as selecting it so that it's then ready to be bound to the selection in the other.
What I'm wanting to know, and having a hard time figuring out, is how do you get such a search function to work on DataGridViews that I have bound to these read only stored procedures? How do I search and select within the DataGridView? And then how would I go about using the selection from two different datagridviews and putting those as parameters in the stored procedure that I wanted to use to then record the relationship in the database?
I have two tables Employees and CafeLogs. Some employees can be cashiers and also customers at the Cafe shop.
Table structures:
Employees: EmployeeId(PK) , FirstName, LastName
CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table
Table relationship:
Employees 1:N CafeLogs (CashierId (FK))
[code]....
Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.
Dim query = From log In db.CafeLogs _
Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _
Select log.LogId, emp.FirsName, emp.LastName, log.Value
I have two table called
1.Register product table
2.Sell product table
Register product table consist of (Product Id (txtProdId.text) and Product Name(txtProdName.text)) NB. All are textboxes Sell product table consist of (Product Name(cboProdName.text) and ProdPrice (txtProdCost.text)). NB. ProductName over here is a combobox.
When someone saves record in the Register product table, items should be added into the combobox into Sell product table.
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

Alright I have a DataGridView, where the user can click on the column headers to sort. When they add a new row while a sort is applied, the record isn't created until the moment they validate the row(which they cannot do till they exit the newRow). How can I make the row be selected once it is sorted?The DataGridView is databound.The selection mode for the grid is full row.I'm using VB.NET with SQLite database backend.I suspect I need to use the RowsAdded event, or DataBindingComplete events. The records in question do have a unique GUID attached but it is NOT visible in the DataGridView.

View 4 Replieshow to add a new row to a table via visual basic 2008, this is what I have been trying and it does not seem to work
newdatarow = dataset.table.newrow
I have an access database with a couple of tables (each with a couple of fields).
in the vb form i have databindsource for two tables each table's fields are shown in textboxes (whose displaymember has been set to each field).
I tried adding a new row to the table like this:
Mbindingsource1.addnew()
textbox1.text="df"
textbox2.text="tttt"
me.Mbindingsource1adapter.update(me.missiondataset.Mtable)
I don't get it, it works just fine for one table but doesn't work for the other which simply doesn't add anything.
I am already exporting datagridview to ms excel and I need to add a row for "Total" but I've encountered a problem because I don't know how to merge the cells for my "Total" since the code for that is placed in a for-loop, there is no exact cells to be assigned for "Total" because it depends on the number of rows in the table. As a result, "Total" is placed in each cell in a row at the end of the table.
