I'm trying to use a datagrid for data entry. I've created a couple of combo
box columns using information from
http://64.78.52.104/FAQ/WinForms/FAQ_c44c.asp#q480q
That example basically sets every combobox in a given column (for every row)
to the same datasource.
One obstacle I have to overcome is when a user changes a value in one
column, the next combobox in the next column on the same row needs to bind to
a new set of data, and...

Hello,
I know this has been discussed a lot already because I've been searching
around for information the last few weeks.
I'm trying to implement a DataGridComboBoxColumn class. I've found
several examples on the web. They all seem to have problems, though
that I've been unable to resolve.
The most promising example I have found is at:

Hay there,
I'm writing my own DataGridComboBoxColumn because .NET 1.1 does not have one
(I hope .NET 2.0 supplies one). I based it on this article:
http://msdn.microsoft.com/msdnmag/issues/03/08/DataGrids/default.aspx
I have a problem when there are two DataGrid's on one form, and when I
switch focus from one grid to the other. To be more precise, when I'm editing
a combo box column in one grid, and then click in the combo column of...

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...

i have a datagrid in my form that has a combobox in it. the actual
data of a combobox is a number because this is a foreign key from
another table. i can create tag successfully in combobox located in
form but not inside the datagrid.
this is the sample combobox that i have created that has no problem
With cboProgram
.DataSource = DsStudentCourse1
.DisplayMember = "Program.ProgramTitle"
.ValueMember = "Program.ProgramID"

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,
I have a problem with a ComboBox bound to a DataView.
The ComboBox shows the correct number of rows but instead of the data, each
row shows "System.Data.DataRowView"
Can someone explain how to fix this and why it is happening?
The Form's Class has:
Imports DataAccessLayer
'Class that retrieves data as a DataSet

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
