Has anyone experienced problems with
a combo box SelectIndex property?
Is there a limit to the number of Items
for a combo box?
Namely, when I set programmatically
ComboBox.SelectIndex property
with 2000 Items listed in the ComboBox,
SelectIndex property accepts assigned
value. However, when I try to use SelectIndex

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 want to be able to compare the old combobox index to the newly
selected combobox index in the SelectIndexChanged event. How can I do
that? I know I could store the last selected value for the combobox
myself and compare that to the new index in the SelectIndexChanged
event, but doesn't VB.Net store this value somewhere so I don't have to?

Hello.
I have a combobox in a form (cmbNames).
The DataSource property is some arraylist of strings.
I have a button which is supposed to "clean" the combobox and deselect any
item.
Therefore, I do:
cmbNames.SelectedIndex = -1;
If index 0 was selected (meaning, the first item on the list) - the combobox
indeed goes to index -1 and there is no selected item.

Hi everyone,
I have a control array that contains two ComboBox and I used a Select Case to make the difference between the ComboBox and I also diferentiate the two ComboBox using their Index value. The problem is that when I run my program I can not see the values that are in the second ComboBox (Index 1) but I can see the values that are in the first ComboBox (Index 0). I have to click on the first ComboBox and then click on the second so I...

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. But how does one go about
overriding a method of the Items...

Hi All,
At first i will give thanks of all who have help me in the other thread. Know my combo works :).
Ok, you know the combo calls a javascript function in the onchage statement.
$combo = "<select name=\"ta\" id=\"ta\" class=\"imputbportada\" WIDTH=\"170\" STYLE=\"width: 170px\" onChange=\"cambia(document.formComprar.Q1,this.val ue)\">\n";
If i try to select a default option, but the onchange don't call the function.

Hi all,
I use ComboxBoxes to input and display lookup field values in a database
table. I want to use the value in database as the index of the items in a
ComboBox so the matching items will be displayed when a record is read.To
boolean value, it starts from 0, for other enums, they start from 1, so I
have to do adjustment in code, is it possible to configure a combobox' index
base instead ?

I've spent the last four hours Google searching for a way to disable
items in a Combobox. I found one example in C++ which I can't get to
work and another in C# that I couldn't get to work either.
Does anyone have some good code for an owner-drawn combobox?

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,...
