i have a combobox containing countries name and their codes like INDIA:CNT001 then i have a textbox that store the code of country i.e CNT001(fetching from database) Now i want to match that code with the combobox code so that the combobox is set to that item when i click a button. i m using vb.net and sql server as database.
View 5 Repliesmy program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)
Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

Normally to add a item to a combobox I just do:
<option value="310">Willmington (310)</option>
But in a vb.net 2008 I am working a windows app to do the same thing, and for the life of me cannot figure out how.This is what I have currently.
While Reader.Read()
frmMain.cboType.Items.Add(Reader("TypeName").ToString)
End While

To add just the item, I can use
combobox1.items.add("New Part")
How can I attach a Value (Like an ID) to this item that can then be accessed from
SelectedID = combobox1.SelectedValue
?
How do you add item(s) to the top of a combobox instead of the end?

View 5 RepliesIn vb6, to add a combobox item, you simply say:
Combo1.AddItem
All easy enough. But how do you do that in VB .NET?

i have two tables. i bound one combo linked to another table value.
my problem is if user wants to add new value to combo how can i add that value to my combo as well as new row to table...
for example :
table 1:
PID,ItemID,Price
table 2:
ItemID,ItemName
i create form for create and modify table1. and i put combo in my form cmbItems for list of all items.
cmbItems.DisplayMember = ItemName
cmbItems.ValueMember = ItemID.
now if user want to add a new item in this form what should i do... and new item should be added in database also....
I have a combobox that is bound to a dataset (via datatable and datatableAdapter). The combobox displays the current data in the table as it should.I have programmatically added the string "ADD..." to the list at the form.shown event:[code]when the user then click on (select) "ADD...", i open a new form to allow the user to add a new item to the list.The code i have behind the "ACCEPT" button on the new form stores the NEW value to the DATASET. I have verified this by previewing the data in the dataset.My problem is getting the combobox to reflect the changes to datatable to which it is bound.[code]

View 2 Repliesvs2005 -vbI have a combobox that gets its values from a call to the db. I have programatically added the list values for the box to match all the possible values that could be pulled from the DB. The user can update these values and update the db entry.I would like to be able to display any entries from the db, however, there is one value on the list that I don't want the user to be able to change the combobox's value to. I'm hoping there is some way to to 'hide' or '.visible=false' for just this one item when the list drops down so the user can't select that value.The box sits in a datagridview. I realize I could use the 'cellbeginedit' & 'cellendedit' events to prevent this action, but I consider that to be a last resort, as I think not showing it on dropdown is preferable code-wise.

I have a combo box with a list of book conditions. When a book is loaded into the form, the condition the book has needs to be selected. How can I do this? Here's what i have: Excellent Very Good Good Fair Poor just for example, how would i select "Good" WITHOUT USING THE INDEX? The database knows the condition text, and condition id. I need to select the condition in the combo box with either. However, I don't know how to add the condition id to the items in the combo box. How would I do this in Visual Basic 2008? **EDIT** I forgot to mention, although i am using a database, i am NOT using SQL Server. I just need a way to select it with a variable containing either the id or condition.

when you can't make use of the item value property in an unbound combobox? I get access to it in html, so one would think you could do it in .Net.
