I am writing a Windows Form app in c# and I've populated a combobox with
values.
I click on the down arrow to display the list and the list of values
displays correctly. Once I select a value, the list disappears and the
selected value does NOT display as the selected item. If I click the down
arrow again and re-select the value, this time it displays.
What's wrong?
Thanks,

Check your code. Somewhere, you must have "Combobox1.Sele ctedIndex =
-1". There is really no other way for this to happen.
One way to check is to capture the event "SelectedIndexC hanged" and
then set a break point there to see how the event is being fired.

Hi,
Check your code, see what methods are handling the selenctedindexc hanged.
Also verify what you do ni that method, if you affect other controls's
status it's possible that the handlers of those other controls do the same
with the combo.

I found my problem - in the course of executing the SelectedItemCha nged event
I was clearing the combobox value list with .Items.Clear.

Hi,
I have a combobox who's data source i set to an array of objects (call
it MyObject). these objects have get properties: key, value, descr. i
set ValueMember to "key", DisplayMember to "descr", and datasource to
the array of MyObjects.
How can i set the selected value of that combobox based on the
ValueMember OR how can i find the index of an item in the combobox BY
ValueMember?

Hello - this started out as a minor annoyance - and now is
starting to bother me more and more - I'm hoping someone
can help me.
I would like to have a combobox display - NOT initially be
blank - but contain a value. However the value is just
for user reference - not really one of the combobox
choices. For example intially the combobox should equal
the word Select - and the item values can be
say 'one', 'two', and 'three'.

I've tried googling for the answer to this problem, without any luck.
I'm sure the truth must be out there somewhere!
I have a multiselect listbox populated with many items (set by the
RowSource property). In my code I cause a number of these to be
selected - but if the first selected item is not within the currently
visible range then there is no change to the display. This gives the
impression that nothing has happened.

I have a combobox that when it drops down the selected item is not
highlighted.
I'm guessing there is a property that controls this but can't find one.
Is there?
Should it always be highlighted?

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,...
