In our VB.Net Windows form application we have a combobox
pre-populated with a list of items. What I need is simply
clear everything from it's dropdown, when a button is
clicked. I tried everything I can think of, such as set
data source to nothing, etc., but still not been able to
make it happen.
Can someone show me how to do it?
Thanks 5 59483
Is it a data control?
If not, then call ComboBox1.Items .Clear

Are you using a databound control?
Try that:
\\\
Me.ComboBox1.It ems.Clear()
///

Thanks for your reply.
The Comobox1.item.c lear doesn't seem to work properly
since have datasource set - I am getting an error message
about this. When I try to set Comobox1.DataSo urce =
Nothing then I can clear the list, but I still have one
line displyed in the combo: System.Data.Dat aRowView. What
should I do with this?

You have to set the data source = nothing
before issuing ..items.clear

Have you tried calling DataTable.Clear on the table that it's bound to?

Below is my code for a combobox. Basically, I have 2 comboboxes. 1

I currently catch the SelectedIndexChanged event on a ComboBox to perform
some processing when the user changes the selected item. But I also want to
know when the user clears the list, but I can't seem to catch any events that
would indicate when this is happening. I've tried SelectedIndexChanged,
SelectedValueChanged, TextChanged.
What can I do to know when the user calls Clear() on the ComboBox items list?
This is .NET v1.1.

What I'm trying to accomplish is:
Disable a ComboBox (not bound to any data) when a .Clear method is
executed.
So far a cboComboBox.Items.Clear does NOT trigger any of the events I
expected it would. I've placed break points in the following events and
still they are not triggered:
Click
SelectedValueChange

Hello:
I have 20, 30 text and combo boxes on one form, and I would like to clear
them up at one time using the statement "With..........End With".
I used this when using VB6, but I don't know if I can use the same way in
VB.Net. If I can't use With statement in VB.Net, what should I do?
Thanks!!

I am populating a ComboBox at run time. I insert the first value of
"Choose Value"
cboTaxValue.Item.Insert(0, "Choose Value")
Then I loop through the rest of the values to be added to the combobox.
My problem is that when I try to clear the ComboBox it clears the items
that were inserted into the ComboBox, but does not clear the item I
selected in the ComboBox... For Instance.

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,...
