I need to have a combobox functionality (ie. be able to type and/or
select from list). I'm using the combobox control from
metabuilders.com. For the most part, this control does exactly what I
want it to do.
One flaw: when i set the autopostback to true, it seems to have no
effect on the control. I have a selectedindexchanged event handler
that is suppose to fire when the index of the user control changes.
It is only fired when the...

I want to set the Default value of a Combobox for any changeable record and have got this working but it is totaly unsatisfactory
see the code below
I loop through the items in the Combo looking for a match between cVal and the selectedValue then stop when I do have a match
the obvious problem is that each iteration fires the selectedIndexChanged but also for a large list this will slow everything down.
There must be a better way

For fun, I am developing a combobox control look-alike.
The only way that I was able to accomplish creating a dropdown list was to
basically show up a form right underneath my custom combobox that acts as
the dropdown. This form does not have any borders on it and it only hosts a
list box control so it looks like a real dropdown.

I have a combobox of dropdownlist style as one of the controls on a
tabbed form.
The list is populated by setting the DataSource property to a dataset
and then the DisplayMember and ValueMember properties are set to the
names of 2 of the fields in the dataset.
I noticed that when the form displays, the combobox defaults to the
first item in the list, not to blank (selectedindex=-1) as I would
have expected. I can use the...

Hey,
I'm trying to find code for an Explorer-style Directory ComboBox. (You know, it display "Desktop", "My Computer", all drives, etc., but it has a treeview control inside the combobox so that you can navigate through the file system as well.) I've found some on the web, but all of them just have the drives and desktop directories and are static in that you cannot expand the directories. I normally build a treeview control to do it with,...

I want to create a combobox with its displaymember populated from a
datatable. But once I get it run, the default display member in the
combobox is always the first row of the displaymember list. even if I
abitrarily set the combobox text to empty string, the value retrieved
from the combobox text is still the first row value from the list. How
can I set, when I display this combobox, the default display text to be
empty, instead of the...

I have a combo box in a subform that will have different options
depending on values in the main form.
I would like the combo box to default to the first value in the list.
Any help would be much appreciated, thanks.

I want to create a customized ComboBox where the methods ComboBox.Items.Add
and ComboBox.Items.Insert will behave thusly:
-- If the item is not present, add it.
-- If the item is present, set the selected index to the item (without
adding a duplicate).
I know the basics of inheriting from user controls, so if this was merely
overriding a method of ComboBox I could do it. I also know how to do this
with a couple lines of code in my main...

I use DataGridView containing DataGridViewComboBoxColumn column.
Combobox column displays dropdown list opening selection triangle in all
rows. This covers part of visible data if columns are narrow.
How to force dropdown list opening control to appear only in active
(current) row ?

Hi, Im tyring to display a dataGridView with comboBoxes on about 5 of the fields. This table is basically permissions to certain parts of my program. In the database i just store a 1 or a 0 (access or no access). Now obviously to the user i want this to be displayed as text. Now currently i am creating the columns manually and using the cell changed event to do the updating. This is quite long winded and if possible i would like a simpler...

Overview:
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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
