I am trying to use a DataGridView to display one column of textboxes with a
single value from a query and then next to it have a combobox that displays
results from another query. What happens is the second query just returns 1
value to each combobox. So, in other words, for each textbox, the next
result of the second query puts 1 value in the corresponding combobox.
Here is my code... What the heck am I doing wrong????

Hi,
I have a problem with the DatagridView of VB 2005.
In a DatagridView I have a databound DataGridViewComboBoxColumn. My
problem is now, that if I click in the header of this column, VB sorts
the grid on the ValueMember (which is a non-significant ID number) and
not on the DisplayMember (which is a significant text).
This is for the user very confusing, because he sees a list that is not

How do other people get around having to define the ValueMember in a

I'm currently doing the following, and it feels wrong and woefully
misguided.

Hi
I have a little application that does datavalidation.
It supports dynamically loaded plugins (you drop a dll with a class
implementing IValidator<Tin the same dir as the main application).
All classes that implement this interface are shown in a drop down in
a DataGridViewComboBoxColumn named Validator.
By choosing the class to validate this specific data in the drop
downbox IValidator<T>.Validate is called and returns true/false....

display member: (concatinated field) Surname &' '& Forename &' '& MembershipNo & - & DateofBirth as `Memberdetails`

I would like to sort the combo box by surname/MemberDetails but it currently only sorts by membershipNo. I have tried the sorted = true value which does sort by surname but does not sort the Valuemember:...

I have tried to use the DataGridComboBoxColumn object with limited success.
What I want to do is to create one new unbound column to be a combo box (so
far, this has worked), populate it with items from the database (this also
has worked). But, now I want to be able to have the user select one of the
items in that combo box and fire off an event to select more data from the
database based on what the user selected in the combo box.
Well,...

I have a datagridview containing a datagridviewcombobox.
The combobox has a dataset containing city_name and city_id.
When I select a new city_name in the combobox I would like to return the city_id corresponding to that city_name.
Code:
//City ComboBox
comboboxCity.DataPropertyName = "city_name";
comboboxCity.HeaderText = "City";
comboboxCity.DataSource = city_table;

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:
