View 5 RepliesDatagridview Changes Do Not Update To Database
Mar 31, 2012I have an application doing the following:
- Treeview with customers
- on clicking a treeview, for every project of this customer, a new MDIchild opens, where the products of this project are displayed
- the MDIchild is basically a DataGridView, which is connected to the products-table via a DataView
my Problem comes after changing a value in the products DataGridView:
- if i do not change the row, the changes will not go back to the database after an update
- if i do change the row after entering a new value, everything works fine
The strange thing is, that in both cases, the value in the DataTable is changed, the DataSet is "hasChanges=True" and the DataRow's state is "Modified".

Update The Database Through DatagridView?
Apr 3, 2008I am using VB NET 2005 and Sql server 2000.I have 2 tables which have 1 to M relationship.let's say:ProductionMaster (ModelNo, Description)ProductionDetails (ModelNo, ItemNo, ItemDescription, QuantityPer)once the form load, I fill the tblProductionMaster which ModelNo into txtModelNo.so once the txtModelNo got event "Changed", the datagrid will be filled base on ModelNo. (in this case I use dataset, datatable and dataadapter).but the I only use this query SELECT ItemNo, ItemDescription, QuantityPer FROM tblProductionDetails WHERE ModelNo = '" & txtModelNo.text & "' and filled it into datagridview.the question is how I update the DATABASE if user change the value in datagrid?let's say, user change the ItemNo from "A" to "B" in column ItemNo in datagrid so the rest column (ItemDescription and QuantityPer) will be followed change, how I update the database once the cell lost its focus?

DB/Reporting :: Update Database From DataGridView?
Aug 27, 2009I�m trying to make a simple database editor using DataGridView.I have one DataGridView containing a lot of data on products and some parameters on how they should be tested. Some of these parameters, for example "Test method", is just a number. But if I look in the table for Test Methods that number has lots of other parameters. So if I select a "Test Method" Cell and click a button that table opens in a new form with just that "Test Method" (if I for example have selected a cell with the number 1, Test Method 1 will be shown in the new form). So far everything I�ve said works. I can even change values and update it to database in the first "Products" table. So here is the problem The DataGridView that shows the products is bound to a table and always shows the same thing which makes it easy to change and update using the following code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.INPUT_PRODUCTSTableAdapter.Update(Me.TestPlattformDataSet)
Me.TestPlattformDataSet.AcceptChanges() End Sub
This will change later when I add a search function. Then this will need the same modification aswell. The DataGridView thats shows the other parameters can�t be updated using just this code cause I get an error that says
"InvalidOperationException" "Update requires a valid UpdateCommand when passed DataRow collection with modified rows."
It seems like the problem is that because I change the data under run its not really bound to the database. And I haven�t found any complete solution to this. I have found some similiar problems and it seems I need to update each row using the command
TableAdapter.Update(DataRow)
Here follows the entire code for showing the Parameter Table in a DataGridView. This does not work.

UPDATE And DELETE In Datagridview And Database
Sep 10, 2010I'm trying to get the Update button and my Delete button to work. Please advice me accordingly on what I'm doing wrongly. And as for the delete button, I have little clue of doing it. What I want the Update button to do: Basically I have a datagridview in my form. And the DGV displays all the records I have in my mdb file. The user could edit the records directly at the DGV and when the Update button is clicked, both DGV and database gets updated.

DataAdapter Commands To Update Database From DataGridView
Jun 21, 2010Any tutorial and maybe a sample project that can be downloaded that shows how to update a database such as MS Access from DataAdapter commands in which changes are made in a DataGridView? For example, the DataAdapter contains 2 tables called FirstTable and the other table would be called SecondTable. The DataGridView is based on a query that shows rows from both tables. The actual table that contains the rows to be changed, inserted or deleted is FirstTable.
