Hi there,
is it possible to avoid that a user could enter a text directly in a
combobox?
The user should only select a text from the list of the combobox without
typing anything.
Thanks

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...

This is a repost of an item that I still cannot resolve.
I have 3 combo boxes. The first leads to the second to the third.
When I have selected a value in the second box, the third box shows the
available information based on the second combo box selection. But if I
change my mind and select a different item in the second box, after the
third box has been populated, the third box still retains the information
that was previously...

Avoid autoselect in combobox
In the load procedure of a form I am filling a combobox with data from a
database. The combobox fill the data OK, but it is automatic showing the
first item of the list as the text. How can I avoid the first item in the
list to be selected as default? I want the textbox of the combo to be left
empty until the user select an item.

ComboBox databindng Problem
== How the ComboBox is setup and used:
My comboBox is populated by a lookup table. The ValueMember is the
lookup table's Id and the DisplayMember is the text from a
corresponding field in the lookup table. In my data table we store the
ID in what I will call the 'key' field.

Hi-
I've seen this problem discussed a jillion times but I cannot seem to
implement any advice that makes it work. I am porting a large project from
VB6 to .NET. The issue is using the combo box bound to a table as a lookup,
drawing values from another table to populate the available selections. This
all worked fine in VB6.
I have distilled the problem down to a simple form drawing data from the
Northwind database for a representative...

Hi Everyone,
I am at my wit's end here. I have a combobox (combyQueryTitle) that I
need to use in order to select a query for my database project. Therefore,
I am using the comboQueryTitle_SelectedIndexChanged handler to, when a new
selection is made, update the query and refresh the display. The only
problem is that the program seems to inexplicably start with the
..selectedindex property at -1! This makes no sense to me. ...

I've been reading all the help I can on the topic (MSDN, other) but I
can't make sense of this.
Desired behavior;
The user is to choose from the displayed list of the databound combobox
and the coresponding 'Id' from the lookup table is to be inserted into
the field of the new record.
I have two simple tables. "tblPerson" is the data table. The lookup

I have a combobox with items like this: {one,two,three}. The selected
index is 0, so "one" appears in the combobox text. When the user drops
down the list, and selects "two", for example, I modify the Items
collection to be {two,one,three} and now want "two" to appear in the
combobox text. However, the combobox text is now blank. the is apparently
somehow the result of having changed the combobox.Items collection.

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:
