I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

I have a main form with player information (it's a sports application). To add or edit a player the user presses a button which opens another form. They either add or edit from this point. When they click 'OK', it saves the data to the database table then goes back to the main form. The amended or new info doesn't appear. If they close the application, then reopen, the new info appears in the datagrid now.
how I can get the datagrid to refresh once I press 'OK' on the input form?

I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary
User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.
How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?
I have a mature VB6 program that depends heavily on flexgrids for the display.It appears that DataGrids are somewhat of a replacement for flexgrid?I need to update individual cells over and over and I don't see how to address a single cell. Appears to me that most samples are tied to a database which I don't have.If I set up a datagrid that is say 3x3, how do I read and write from and to say the center cell?

I'm at the moment busy with a project for school. Well I have a datagridview that displays all of the employees within the company. But I want to be able to change, delete or add new employees in the datagridview and then save it in the actual database. I used this code to do that.
Me.Validate()
Me.TblPersonnelBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.DtsPersonnel)
But when I run my program and click on the save button I get this error message:
Application Exception was unhandled
TableAdapterManager contains no connection information. Set each TableAdapterManager TableAdapter property to a valid TableAdapter instance.How can I get around this? I think it has to do that my dataset exists out of 1 table but actually it contains items from 2 tables. Would this be the problem?I need to have the dataset like that though otherwise other parts of the program won't work.

View 4 RepliesWe use an ERP program in conjuction with SQL server and lots of tables that keep track of product records customers and all these kinds of stuff. I am building a fairly simple Warehouse Inventory Application that warehouse employees will use to count and inventory stock on hand from products around the warehouse and then check if any quantity errors occur between stock on hand and logistic quantities.I have created a custom Inventory table that I would populate with records like {stock_code, Description, Quantity_remain, quantity_avail}. Those records already exist in 2 different tables in my database. The aim is that I want my program to fetch daily 10 random codes from the stck table, and records about their quantities,bringing together the "columns" that my new custom table has +2 more editable columns: inventory, date, user with a query like this:[code]
As you can imagine my custom table contains the exact same fields as the query suggests + 3 more.I use the the stck table to fetch product info like its code,description, its group_code, categ_code, and then I outer join the stck_x_th that contains records concerning quantities remaining or available asociated with each product code and the "places" those quantities reside in the warehouse.Then, store them in a datagridview control, with only one editable column -inventory- (user and date columns are auto-populated with default values), and then when the user fills out the inventory quantites, I want to save the datagrid "as it is" in my new custom table.I am creating a databound gridview control using one table adapter (which refers to the inventory table). Then I add to my table adapter using "add query" the forementioned query with a fillby method to populate the Datagrid (and therefore my Table in SQL) with the exact same values my query returned from the different tables. But whenever I try to update the table concurrency exceptions raise.It works like a charm if I enter the values in the grid cells manually, without populating the grid control with the new fillby method my self but not if I populate the grid via a query and then hit update.
