Combobox.items.add - Combobox To Have A List Of Choices From A Table In A Db

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.

Select A Particular Value On A Combobox By Looping Through Combobox Items?

Jan 5, 2012

I 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")

Trying To Add Items From ListBox To Insert Into Textbox

Oct 14, 2009

So the on this application a user will click a workgoup then a location then when they add the workshop it will and the prices to gether and put them in the lstCost, while doing that it also puts the price in the lblTotalCost.Text. Now the problem I am having is when a user adds more then on workgroup and location the lbltotalCost is geting what ever the last line in the lstCost is and multiplying the last line by the index number that it is so if the last line is line 2 then it will * 2 for line 3 then *3 of what ever the price is. Heres what I have so far...

Using An Array To Insert Items Into A Textbox?

Apr 27, 2011

I am having some trouble splitting a string within an array into 2 values. For example in my textbox I have several lines of measurements that are Length x Width: 20x14, 10x8, 16x13. Each measurement is on its own line. I'm trying to split all Width values that are greater than 12 into 2 separate measurements, so with that last example, I would have 5 measurements (LxW): 20x12, 20x2, 10x8, 16x12, 16x1, then I would like to add these measurements to a new textbox with each measurement on its own line.

Here is the code I have so far. Again, I am very new to programming and this is the first serious project for me since "Hello World", so what I have might be way off. Thanks in advance.

Dim room As String = RoomsTextBox.Text
If room.EndsWith(vbCrLf) Then room = room.Substring(0, room.Length - vbCrLf.Length)
Dim roomarray() As String = room.Split(vbCrLf)

2 Items With Same Name In Combobox?

Oct 28, 2009

I 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.

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

I need to display the CustomerName but return the CustomerNumber of the selected customer

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

Combobox Items Maintenance ?

Feb 24, 2011

I'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?

Combobox Performance Many Items?

Oct 28, 2008

So, 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.

Is it possible to disable some items in a combobox?Depending on the current mode that my application is in, certain items need to be enabled or disabled.I know that I could remove the items and rebuild the combobox but in this case I think that by showing the items greyed out it gives the user feedback as to what mode they are in and what options would be available to them if they decided to switch modes.
