G'day,
After doing much searching and pinching bits of ideas from here there and
everywhere I came up with a fairly 'clean' solution of including a comboBox
into a dataGrid column.
You can download a fully working C# sample with the Northwind.mdb here:

I have a datagrid containing a single combobox column. It also contains an
'Add New Row' button at the bottom of the datagrid. The datagrid is in a
form that contains 'Save' and 'Restore' buttons. The 'Save' button saves all
the data from the dataset to the database. The 'Restore' button resets the
datagrid to the values contained in it at the last 'Save' operation.
When I have 3 entries (rows) populated within the datagrid. If I delete...

I'm sure this is a fairly basic question, but I've been looking all over the
web for days for suggestions on how to do this.
I've got a datagrid that's bound to a dataset on my form. It includes
several columns, the last of which (with the header Quantity) contains int16
values. When a user selects a row, I would like to have a combobox on the
form display the values from 1 to the number in the Quantity column (e.g.,
the selected row has...

OK. So I've been to http://www.syncfusion.com/FAQ/WinForms/FAQ_c44c.asp and learned a lot about what I might do with a datagrid. But I'm STILL not able to do what I want to do. I want to be able be able to enter data into my grid cell using a combobox. I want the combobox to display items based on my selected DisplayMember and update the datasource based on my selected ValueMember. So far, so good. But when the user leaves the combobox...

I have derived a ComboBoxColumnStyle that inherits DataGridColumnStyle. It works fine except for one behavior. If the user selects a new value from the ComboBox's pulldown list on a brand new record, the ComboBoxColumn's Commit event doesn't fire. If the user first edits a TextBox cell on the same New row, and THEN selects a new value for the ComboBox cell, Commit fires. What is going on and how do I get around it
Thanks
Pat

Hi
I have a datagrid with a combo box,
I need to populate the combo with data dependant on the record value.
eg for record 1, field Warehouse = 2R so combo would allow selection of
locations valid for 2R
record 2 has Warehouse = 2M so combo on that row has a selection of
locations valid for 2M
I can set the combo datasource but can't see how to set it on a row by row
basis.

Hi,
Forgive me for posting this message in 2 groups -- it appears that the Data
Access group isn't very active, so I'm posting again here:
I have a DataTable that I want to fill using a DataGridView. I've set the
DataSource of the DataGridView to my DataTable. My problem is that I want
some of the columns to be drop downs. For example, the user will need to
enter a "product" into one of the columns. There is a list of "products" in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
