I am creating a program to help tutor Paramedics students and the drugs they need to memorize during there classes. I have a form that presents to a student a Trade Name of one of these drugs and then they have a selection of 4 possible generic names to match to. These generic names are then presented to the student with 4 Radio buttons.I want all 4 of these Radio Button to be in Deselected mode when the form presents itself to the student with the Drug names.I have set all 4 radio buttons to "Checked=False", but when I 'F5' to test, the first button always comes up selected. I even tried to put in the Form_Load area,
Private Sub TradeGeneric_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.rbGenericName1.Checked = False
Me.rbGenericName2.Checked = False

When one item, in the listview, is clicked, it is selected.
I want to unselect the item when (1) it is clicked again or (2) user clicks into an empty area of the listview.
I've looked into getitemat, but turns out listview does not have that in WPF. I've posted a thread asking about GetItemAt separately, but haven't had any proper info so far.
1, About the left arrow on datagrid. How can I set the left arrow on datagrid to the selected row?2, I got multiple data display on my datagrid. For example, the value of the data is 1,2,4,6,10 like that. Now first I search the value 1 then it will select the row in datagrid with the value 1 and then if next, I search the value 6, it will unselect the row with value 1 and point to the row with value 6.But now the problem is, when I first search for value 6, it will point to the row with value 6 but if after that, I search for the value 2, it wont unselect the row with value 6 and select the row with value 2. It will select both row with value 2 and 6. So what is the problem with my code??

I need window1.xaml through window6.xaml to appear in the combobox on my admin form.
Here's my scenario...I have 2 datagridviews in my Windows Application.When I click on a row in the parentgrid, a child grid shows up with data regarding to which I have clicked.both grids are from the Database (SQL2005) only. In the child grid am using a combobox and that is my headache...this part is working fine and the problem is in the child grid.
When I try to add a new data (at the sametime into the Parent and Child) its working fine and am able to insert data into the tables...
But when I want to edit a data in the child grid, the combobox is making problem.I selected a value from the combobox and go to the next cell OMG the combobox value changed to the corresponding ID of that instead of showing the text.But I neglected this as I was getting the correct value tat has to be inserted into the DB.
Now while editing the main data am tryn to add a new child data ( assume that there are few child data already and am adding a new one).When I click save the values in the combobox are retreived as string and am not able to update the database.This happens to the rows that were already there.the reason is because of the strange behaviour of Combobox in the grid..
Am after this for 2 days and still after this..
Also am populating the combobox from the DB only.
Find the code below, how I did the combobox population
CODE:
I have a combo box having multiple items and I want by typing the item should select automatically and combo box style should be "DropdownList" type.Let�s say I am typing "I" then country like "India", "Indonesia�,� Italy" should sort automatically. It is happening by default in VB.NET for one character.But I want If I type "India" this should select "India" instead of "a...." because my last character is a. in VB.Net it is selecting country like starts with "a�. But I want the full typing option should be present for the combo box.
View 1 RepliesThis seems to be the toughest thing I've had to search for. It seems there's not a good thread that clearly explains how to add items to a combo box that's bound to a SQL Server table (of course, I'm a newbie so I'd like a step-by-step on how to get it done).
View 5 RepliesI 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.
I am totally new to VB.NET and Visual Studio. I am creating a new form, which includes a combobox. I have figured out how to add the items to the combobox using the properties box, but I would rather code them. I tried the below code, but no luck. Any ideas what I am doing wrong? Me.cboSTATUS.Items.Add("A")

On my first form, I have a combobox that is bound to the Locations table and displays all the different locations. Once a location is selected, a 2nd form is loaded which has textboxes which are also bound to the Locations table and are populated with the corresponding data.
Here's my issue: on the 2nd form, I have combobox that is bound to the Offices table. Currently, when this form loads all the available offices, displaying with the first office in the list. I need it to populate with the correct office based on the selection made on the combobox on the first form. I guess what I'm asking is, how does one bind a combobox to a foreign key b/c it is the foreign key, office_refnbr, from the Locations table that needs to display in the Office combobox.
I've tried a variety of bindings, including:[code...]

I am successfully hiding a combobox, based on the selection of another combobox. However, I can not get the label of the combobox to hide as well. The code I am using, which is basically the same code for hiding the combobox itself returns the following error:

Here is the code I am using for the label:
Me.DOCUMENT_EVALLabel.Visible = (EVALUATIONComboBox.Text = "Text")

Nevertheless, mycontrol remains empty after this.
I 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.

I am having a problem to get the results of a combobox when the user uses the tab key to exit the combobox. The combobox uses a database as the datasource. When the user uses the mouse to click on the selection the selectedindex is set proprerly, however when the user will enter some text and presses the tab key, selectedindex is set to -1.
I have attached some test code to duplicate the issue.
