I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.
ComboBox Items From A DataGridView Column?
Jan 8, 2009I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

View 16 RepliesCombo Box Using Items Collection Bound To A Database Table / Dataset Is Not Recognizing Changes
Apr 14, 2009Visual studio 2005 - vb.net..I have a user control on a form containing 15 combo boxes.All contain Y, N, and blank (for Yes, No, or blank) in the Items Collection property.Each of the combo boxes have a binding source to the same table, different fields.When you select a value Y, N, or blank for any of the fields and do a save, the values save while the application is open.Once you close and reopen, the values are gone.It appears the dataset does not recognize the change, so the values are not getting stored in the database table. Is there something I can do or put in one of the events that would identify this as a change.

Select A Particular Value On A Combobox By Looping Through Combobox Items?
Jan 5, 2012I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.
Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....
I'm using the following code for doing so:
Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database
Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")

2 Items With Same Name In Combobox?
Oct 28, 2009I have a combobox in an app that auto-populate. Some of the items have the same name and so there is the problem: when an item is selected and there is another one w/ the same name , when the combobox is clicked again, the fisrt item with that name is selected, not the one that was clicked.
for example:
there is a combobox with the following items:
aaa
bbb
ccc
ddd
ccc
I open the combobox. I click the last ccc. I open the combobox again and the first ccc is selected, not the last.

View 21 RepliesDisable Some Items From The Table By Setting A Value In The Table?
Dec 7, 2011I have a combobox that retrieves data from a database. Occassionally i have to disable some items from the table by setting a value in the table so that item is not available in the dropdown for users. I do this through my SQL query i.e.SELECT * FROM TABLE WHERE ADDITEMTODROPDOWN=1
When i have the DropDownStyle set to normal (dropdown) and the application loads the dropdown shows the item from the database which is no longer available for users to select (the item is set to disabled or this is fine and is what im after. I then change the DropDownStyle to DropDownList to make it look like a button so users cannot enter their own items. As soon as i load the form with the combobox the item that i disabled no longer appears as the original text.

Adding Items To A Combobox?
Nov 27, 2007In VB.Net for an ASP project I was able to do the following:

However in a VB.Net Windows Project it won't let me duplicate this.

I am also adding the items in code because they are changing based on changing values.

View 7 RepliesCombobox Items Maintenance ?
Feb 24, 2011I'm in the process of converting an Access 2007 database to vb.net (in visual studio 2010). I want the user to be able to maintain the items in these comboboxes....adding, updating, and deleting any item they choose. In Access, I had a button which would display the combobox items and allow the user to maintain. Upon leaving this display, the combobox would be refreshed. Is this the best practice for vb.net? Would it be any different than what I'm doing now in Access?
View 5 RepliesCombobox Performance Many Items?
Oct 28, 2008So, I've been reading around on the internet and through MSDN trying to find a way to add thousands of items to a combobox without taking 12 seconds.I KNOW, I'm going to incite reflex-responses involving: bad design; use categories and filter; use BeginUpdate ...Here's the thing.I've read through a lot of similiar forum questions as the one I'm asking and none really seemed to answer the question, but these responses are common.The problem is, there is no way to further categorize.I have thousands of customers and each customer can have anywhere from 1 to tens of thousands of designs.The designs have to IDs: DesignID and DesignTitle. The data entry people sometimes have the one and sometimes have the other. If they have the DesignID than all they've got is a number ranging from 1 to (at this time) 60,000. One Customer has 11000 designs. I don't know of any way to further categorize.The reason I use a combobox is for autocomplete. Also, with most customers there are only 10-20 designs, but for some there are thousands.I have to have one practical solution that handles all possibilities.
As far as BeginUpdate or SuspendLayout is concerned, neither have any effect.The sad thing is, the DataSource takes less than a second to load from my DataBase.It's just the setting of the datasource for the combobox that takes so long.It seems to iterate through the entire list once for the bindingsource and then again when I set the DisplayMember.I can set the display member before I set the binding source but that doesn't make any difference in terms of performance.Performance is improved by almost half when I don't use a BindingSource and just set the Combo's DataSource to the List directly, but, sadly, I need to use the bindingSource because there are multiple Combos using the same list.I know WPF uses virtualization for it's combos,.On the internet I found a Technical document on how to implement a Virtual Combobox in C#, but the code was incomplete and I don't really have the time to spend several days creating and debugging something like that.
