View 5 RepliesCombobox - Drop Down In .NET?
Sep 11, 2010I have a small requirement and that is: There are two combo boxes on a form and for populating the employee names and roles. I am populating the combo boxes as follows: I have created a class called "DbConnect" and in that there are 02 functions as:
Public Function getEmployees() As DataTable
Dim employeeDS As New DataSet
Dim employeeDA As New SqlDataAdapter("prc_emp_list", conn)
employeeDA.Fill(employeeDS, "employees")

.net - Programmatically Close A ComboBox Drop Down?
Apr 15, 2011In a Windows Form application (VB.NET) I have a combo box and under certain conditions, when the user opens the DropDown list, I want to display a warning message.All of this works well: In the DropDown event, I check the conditions and if required I display the warning message.The problem is that when the user clicks on Yes on the warning message, I move to another tab on the main form and the drop down list still shows even though I've moved away from the tab containing the combo box.I've searched quite a bit and tried to set DroppedDown to False, call OnDropDownClosed, etc but nothing worked.It seems that when I try to close the drop down list from within the DropDown event, it doesn't work.

Drop Down Combobox, A List Of Options Are Available?
Mar 12, 2012Is using Public Property the best way to achieve the following.From a drop down combobox, a list of options are available. Each option in the combobox has a number of public properties that need to be associated with it.When a option is selected, the user will then have two buttons that each call a different sub, the appropriate options are passed to the sub.Each option will always have the same properties required to be passed.So I'm looking at something like this.

Public Property server As String

Forms :: Drop-down List Combobox?
Mar 23, 2010I have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.

View 12 RepliesSelect A ComboBox Item Which Is A Drop Down List
Feb 28, 2011i seem to have a problem when i try to select a ComboBox item which is a drop down list. The ComboBox contains a list of various items where the user can select from a list, the type of query he/she would like to perform on an Access Database. Two of the items in the Drop Down List are "Employee Sales Between Specified Weeks" and the other item is "Employee Sales Between Specified Months" (without quotation). Now in my VB code, i have a really long If/ElseIf Statement which includes all the options the user can select. Additionally, if the user has selected a week query, he/she must select a From Week, a To Week and a Year (for example week 3 to week 5 year 2009). From Week is another combobox (1-53 weeks) and To Week is also another ComboBox (1-53).When the user selects a month query, he/she should select a From Month from a ComboBox (1-12) and a To Month from another ComboBox (1-12) and the year from the same Combobox (e.g 2009).

View 2 RepliesComboBox Problem - Combo Box Won't Drop Down After Cancelling Validation?
Feb 24, 2012I've found some unexpected behaviour in my ComboBox, which I'm hoping someone can help me with. If focus is lost by pressing the Return key on a form which has AcceptButton set, then after handling the Validating event and cancelling the validation,the ComboBox will not drop down any more. When you click on the drop-down arrow, the list drops down momentarilly then goes away again To reproduce this, create a new VB.NET Windows Forms application. Drop a Combo Box and a Button onto the default form, then add the following code:[code]....
Run this application, click on the Combo Box, enter some random text (e.g. "asdf"), then press Return. After this, click on the drop-down arrow on the Combo Box.I'm using Visual Basic 2010 Express on Windows 7 Home Premium.
DataGridView Combobox Drop Down Item Select Query
Jun 14, 2012I have set the combo box dropdown style to dropdown, the auto complete mode to suggest append and the auto complete source to list items. This works fine IF I choose the required item using the mouse. If I type the full item name into the combo box, it is displayed but not selected for use. Is it possible to use a key such as TAB or Return to select the item in the combo box's display area after the drop down window has closed?

VS 2005 - ListView Drag And Drop
May 20, 2011In the attached program, I have 3 listviews.
1 is Source Invoices
2 and 3 is Customers.
When I drag something from ListView1 - it stays there, and turns a different color to show it has already been assigned. It stays in the list. This is what I want. When I drag something between 2 and 3, it should delete from the source and clone to the destination. It does this when I move 1 at a time, but if I select multiples (try 5 records) it does 3 of them, then the source list gets an error:
System.NullReferenceException: Object reference not set to an instance of an object.
If I highlight all 5 items in list 2 or 3 - then select the top item as the item to drag across, it seems to work.
If I highlight all 5 items in list 2 or 3 - then select the middle item as the item to drag across, it seems to NOT work.
I have tried going from top of list to bottom. Then thought, since I am deleting rows, maybe I should start at bottom and work up. Same thing?
