VS 2010 Datagridview Update From Query?
Apr 17, 2010
I have a datagridview and i want it to display the results from a query. How would i go about doing this. Here is my code so far:
Dim searchStr As String = S_date_menuItem.Text.Remove(0, S_date_menuItem.Text.IndexOf("'") + 1)
searchStr = searchStr.TrimEnd("'")
adapter = New OleDb.OleDbDataAdapter("select * from account where Date= @Date", acctconstr)
adapter.SelectCommand.Parameters.AddWithValue("@Date", searchStr)
that is my query but i don't know how to get my datagrid to display the results.

I need to run a query when I add/Change a value in my first column in a datagridview. When I add a value (a identifier from a table) in my first column, then I need the query to retrive the rest of the values in the table recordset. When I try to run a query, all i get is a query that updates my whole datagridview, and not only one row, with this code in the CellValueChanged module of the datagridview:
Me.myTableTableAdapter.FillBymyQuery(Me.myDatabaseDataSet.myTable, CType(DataGridView1.CurrentRow.Cells(0).Value, Integer))
Is there anyone who knows what I have to do, so I can add several rows to my datagridview, and let a query retrive my recordset based on my value in the first datagridview column?

I have been working on a simple delete and update thrugh the TableAdapter in Express 2010 and can't get it to update after a delete query. The same TableAdapter works fine when I do an 'Add', but not after the delete. What am I missing? I could use the SQL commands, but would like to use the software commands instead. Here is the delete code:

When I try to add an Update query, then open the Query Builder, I get an error saying: Error in table name or view name in UPDATE clause. Unable to parse query text. The only code that is in the Query Builder is UPDATE How would I fix this? If this is needed, the table name is Authentication, column names are AuthKeys, and Available.

This query fails on a dataset when I add the rating wildcard. The other two are fine but it does not like the %. This works fine if I run the SQL directly on SQL server.
HTML
SELECT Rating, InvDescrption, FullJobNumber, Product
FROM vJobLines
WHERE Product Like ? AND InvDescrption Like ? AND Rating Like The product and InvDescription fields are NvarChar where the Rating is Int32.

I'm creating a form application using vb. I'm still new to this and I'm teaching myself via the internet so please don't be too mean. I wrote my code using queries that I created in visual studio. I don't quite remember how to create an update query and write the code to update different datagrids. I tried searching the forums, and I can't find anything that fits into the way I wrote my code. I have an update button that I want to use to save all the edited data in the form. Here's my code so far:
Public Class Form1
Private Sub Blsys_systemsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.Validate()
Me.Blsys_systemsBindingSource.EndEdit()

I COMPLETELY understand how redundant this is but I NEED it.Upon users creating a User account which only contains the ID, Username, Password and CustomerID I must also have a record in Customers create itself but null everything and the User.User_Customer_ID must update to the newly created Customer.Customer_ID
I have everything working but this pesky update query. The ONLY thing it needs to do is change User.User_Customer_ID to Customer.Customer_ID I managed to story the User.User_ID in an integer called UserID and Customer.Customer_ID in an integer called CustomerID I have tried a million different ways with no success

I am not getting any errors. But the update query is not executed as it does not change the database.

I am beginning to work with .NET technology after several years of VB6 and C++ and I want to learn as fast as possible.
My problem is with a DGV. It shows the prices of several store items, and I intend to let the user modify those prices by entering a % in a textbox (radio button states if that % is positive or negative) or by editing cell by cell manually.
As editing prices is kind of sensitive, what I do is loop through the DGV, add or substract the % engtered in the corresponding column and ask for a confirmation after whole DGV loop is done. If user agrees, DB is updated with new values. No problem here.
If user denies (in case he/she made a mistake), I restore grid's DataSource to a copy I made before calculating new percentages and this automatically refreshes my grid to its original state.
The issue is that if a user denies the operation for a 2nd time, this 2nd execution of the code fails at showing the original values, disabling the pseudo-rollback function.
Here is the code:
.
.
.
If MessageBox.Show(mensaje, "Actualizo", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) = DialogResult.Yes Then
[Code]...
remember this works OK if user denis once. What am I missing regarding DataSources or its Tables? Is there anything like .Redraw?
Btw, I tried update, refresh and I also used a sleep function (this helped me a few times back in VB6...).
