Populating ComboBox Based On Selected Item In First One

Jan 10, 2012

I want to populate the combobox based on the selected item in the first combobox. The following code is written in vb.net 2008

Public Class Form1 Sub fillcombo()
strsql = "select * from device"
Dim cmd As New OleDb.OleDbCommand
cmd.CommandText = strsql
cmd.Connection = con
[Code] .....

For this code I am able to populate the first combobox and when I select the specific item in combobox then the second combobox shows only the first element of that item.

In MS access 2007 I have created 2 tables:
1) Contains the device ex:computer
2) Contains the device and its parts ex: cpu, monitor so here the device has duplicate values
Table names are device and parts.

Add New Item To Databound Combobox

May 2, 2012

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]

Forms :: Add Item To Databound ComboBox?

Sep 7, 2009

I started a Windows app using all code for database connection and validation. However, it was always losing the formatting that I had set at run time. So I thought I would use the long tedious process of using all of the studios objects with minimum code.

I am now at the position where I am mostly happy with the layout and how this operates. However, I want to be able to add a non-databound value to a databound combo box. I have set the properties for the combo box in the combo box tasks.

Also, I want to add the ability for the user to update that table that is bound to this control, when a value is not in the list. I know that there is a NotInList event in Access, but I can not find it in VB.Net. I did get so far with updating from the combo box using the Leave event. However, when the database was updated the control could not find the ID in the Clients table to save to the Quotes table.

VS 2008 - Change Individual Item Color In DataBound ComboBox

May 8, 2009

I have a combobox called cbMaterialType on a windows form that's bound to a table in SQL - everything loads great and the combobox displays 'Material' items as it should, in that table I have two fields - Material (as mentioned above) which is a char(25) and InStock which is an nchar(1). If the InStock field contains a '1', I'd like the individual material to be green in the combobox, if '0', then red. I have the simple code in the drawitem event of the combobox as follows, but can't seem to get any results at all:

Private Sub cbMaterialType_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles cbMaterialType.DrawItem
If MaterialTableAdapter1.GetData.Item(cbMaterialType.SelectedIndex).InStock = 1 Then
cbMaterialType.ForeColor = System.Drawing.Color.Green
Else
cbMaterialType.ForeColor = System.Drawing.Color.Red
End If
End Sub

I've never worked with any form of color in comboboxes before and this is my first attempt at the drawitem event.

Delete Selected Listbox1 Item And Listbox2 Item With Same Value?

Mar 1, 2012

I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.

Change List Of Combobox A Based On Item Chosen From Combobox B?

Jun 17, 2011

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.

SelectedIndex : Gets Or Sets The Zero-based Index Of The Currently Selected Item In A ListBox?

Jun 7, 2012

First of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:

When I access the Programing guide, I see that:

ListBox.SelectedIndex Property

Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:

If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then

This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:
