Add Item In Combo?
Jan 9, 2009I'm having some weird trouble with adding a new value in a combobox.The combobox has a datasource which is a bindingsource.The combobox's list is filled from a different table through a different bindingsource. Combobox.valuemember = "ID" and Combobox.displaymember = "Description".When a user types a value in the list, I want to add the new value to the table which is the source for the list. (Which is not the problem, but I don't get that far) The problem is that when the user types a new value in the box, it totally disappears as soon as the user tabs out of the combobox. So, in the event combobox.Validating the combobox.text property (nor any other property) does not show the new typed value.

View 2 RepliesIf Eval Compare Item 1 And Item 2 If Item 1 ="0" And Item 2 > "0.00" = Display Result
Jan 21, 2012Is it possible to compare 2 dataitems and then display the result depending on the 2 values using if eval at run time?I have a ListView with databound controls. 1 is RedemptionChoice and the 2 is CashBack.When 1 reads "0" and 2 reads > 0.00 the output should read AUTO I have read many comments online and most point to create a new function within code behind but have found it impossible to implement on my own.I tried this as a test on the actual page:
<%# If(Eval("CashBackRedemptionChoice").Equals("0") & Eval("[CashBack]").Equals("0.00"), "Auto Cashback"))%>
2 needs to be greater than 0.00 for AUTO to be displayed. Hence I know this would not work. Just trying to give an example of what I would like.
Combo Box - Assign Value To Each Item?
Dec 20, 2010assign a particular value to each item in a combo box? Or, alternatively, some similar control? Specifically, I want a drop down list to select from a list of countries. I then want to get the ISO 2 letter abbreviation for the selected country. I could have a section of code like this
selected_country = cmb_country.SelectedItem.ToString()
if selected_country = "Afghanistan" Then
country_code = "AF"
ELSE IF selected_country = "Aland Islands" Then
[code]....
but this will get rather tedious.Is there an easier way to do it? I would like to be able to assign a value to each line in the list, like
Afghanistan, AF
Aland Islands, AX
Albania, AL
then get the value for the selected item. Is this possible? If not with a combo box, then any other control?
Hiding An Item In A Combo Box
Jan 15, 2010I am using VB 2008 Express Edition.
Say I have Combobox1 with items (1)Breakfast (2) Lunch (3)Dinner
and I have combobox2 with items (1)Apples (2)Bananas (3)Grapes(4)Oranges
Now when I choose Breakfast in combobox1, I want user to see all 4 items in combobox2. But when I choose Lunch in combobox1, I only want user to see (1)Bananas(2)Grapes(4)Oranges in combobox2, hiding Apples.
Does anyone know a code where I can hide an item in a combo box depending on the condition?

View 6 RepliesAutomatically Selecting First Item In Combo Box?
Sep 1, 2009When my application starts, it scans the computers registry for COM ports and adds them in the combo box. The combo box first index is just a blank, and the second is COM1, COM2,...COMn. What I want to do is by default, I want my program to select the first COM port in the combo box, so in this case, COM1.
I know I have to use the PORTNAME property of the serial object, but not sure how I would set that equal to the 2nd index of the combo box.
C# - Refresh A Combo Box Item In-place?
Sep 17, 2009The ComboBox Items collection is an ObjectCollection, so of course you can store anything you want in there, but that means you don't get a Text property like you would with, say, a ListViewItem. The ComboBox displays the items by calling ToString() on each item, or using reflection if the DisplayMember property is set.
My ComboBox is in DropDownList mode. I have a situation where I want to refresh the item text of a single item in the list when it gets selected by the user. The problem is that the ComboBox doesn't re-query for the text at any time besides when it loads up, and I can't figure out how else to do what I want besides removing and re-adding the selected item like so:
PlantComboBoxItem selectedItem = cboPlants.SelectedItem as PlantComboBoxItem;
// ...
cboPlants.BeginUpdate();
int selectedIndex = cboPlants.SelectedIndex;
[Code]....
This code works fine, except for the fact that my SelectedIndex event ends up getting fired twice (once on the original user event, and then again when I re-set the property in this code). In this case, it's not a big deal that the event is fired twice, but it's inefficient, and I hate that. I could rig up a flag so it exits the event the second time, but that's hacking.

View 3 RepliesCombo Box - Action When Entered Item Not In List?
Jan 6, 2011I hope this question is sufficiently clear I'm trying to port an application that I wrote in Access VBA to VB 2010 express and SQL Server. In Access, when the user enters an item in a combobox that is not in the item list an event is fired ("not in list") from which I can set up records in related tables. How can I do the same in VB? I can't see any equivalent to the "not in list" event.
To be more explicit with an example. An address consists of Street, e.g. "23 Acacia Drive", Town, e.g."Wilton" and County, e.g. "Oxfordshire". When entering a new address, the form first requires a street entry in a text box. Next, a Town entry in a combo box which is populated with towns already in the address table. If an existing Town is selected the (previously disabled) County field is automatically filled from that town's County as read from the database. If a new Town is entered the County field is enabled and the user either selects an existing County or adds a new one which is added to the database using similar logic on the not in list event.

Why Timer Stops For 1st Selected Item In Combo Box
