I have a vb.net application, and I have a combobox which should contains a display member (text) and a value member (integer).the problem is:I want to set a default value to that combobox when the form load but I don't have a load event as I create the form and the combobox dynamically. i have used the combobox.selectedvalue =6 but it doesn't work.note: I can't use the selectedindex property because sometimes the value comes from a DB table primary key which is not the same as the combobox index.
the code:
Private Sub fill_combo(ByRef combo As ComboBox, ByVal nodes As HashMap)
Dim comboData = New BindingList(Of KeyValuePair(Of Integer, String))
nodes.movefirst()
Do While Not nodes.eof
I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default. The name is stored in a public variable 'PubName' and I do not want the user to be able to type into the combobox themselves.Is this possible?
I can not locate the correct method to make the first item in a combo box visible.
The app starts with an empty combo box. The user makes a radio box selection then clicks Go! (how original). The combo box is loaded via an LDAP query. All this is working just fine. The problem is the combo box still appears to the user to be empty. They must click the arrow to see the options.
How do I make the first option 'visible' after the users clicks Go!?

OK i have a combobox on the form. I have entered 4 values. I have left the TEXT field blank.Is there any way i can set the default SELECTEDINDEX of the combobox in the form design window.

I programatically / runtime created combobox and bind it to a datasource but can not set its default value. Since I am using the Handler of SelectedValueChanged, this is causing the program to mis-fire. Here is the code I am using.
Public WithEvents T_combo as ComboBox 'dictionary holds data to use in other parts of program Dim T_Dict As New Dictionary(Of String, String)

I have a small section of a windows form that allows users to select when a customer should be called (i.e. day of the week, time and inbound or outbound)When the form is loaded I will extract the information using a dataset and bind to form controls. I want to use a combo box for call stautus - inbound or outbound - however wish to give the user the choice at runtime.My thoughts are I would need to set a static list (so the user could choose) and set the default or displayed value to the info the dataset has extracted.This code to select the index doesnt work when I am comparing the dataset result to the "Outbound" string even though I am using the ToString method.
Private Sub TestTelesalesForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Me.Telesales_DEV004016TableAdapter1.Fill(TelesalesDataset1.Telesales_DEV004016) Me.comboCallStatus.Items.Add("Outbound")

Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.

I am using VB.NET together with ADO.NET to create a program. I have set my TableAdapters as needed and bound the correct tables-columns to my comboboxes.My problem though is this:My combobox2 item is bound to a datatable. The table adapter's Fill method (the select command basicaly) includes a public variable in the where clause to fetch the correct results. I ll put some code here to clarify it a bit more.Public Class Frm_inv
I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.
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.
When I will click the suggested text shown in the combobox it will disappear.My Combobox btw is connected in a database.If I type Kev then kevin and kevsky will show at its suggestion then when I will click any of it ,the combobox text will be empty or will clear what I typed ("Kev") and will not show what I clicked.[code]
I am making a custom ComboBox, inherited from Winforms' standard ComboBox. For my custom ComboBox, I set DrawMode to OwnerDrawFixed and DropDownStyle to DropDownList. Then I write my own OnDrawItem method. But I ended up like this:
How do I make my Custom ComboBox to look like the Standard one?
Update 1: ButtonRenderer After searching all around, I found the ButtonRenderer class. It provides a DrawButton static/shared method which -- as the name implies -- draws the proper 3D button. I'm experimenting with it now.
Update 2: What overwrites my control?I tried using the Graphics properties of various objects I can think of, but I always fail. Finally, I tried the Graphics of the form, and apparently something is overwriting my button.
Here's the code:
Protected Overrides Sub OnDrawItem(ByVal e As System.Windows.Forms.DrawItemEventArgs) Dim TextToDraw As String = _DefaultText __Brush_Window.Color = Color.FromKnownColor(KnownColor.Window)
DataGridView TIPs has TextBoxes and ComboBoxes in it and the data comes from an SQL table. I see how to get or set the cell values that come from the ComboBoxes using Item, but how do I access the actual ComboBox events and properties?
I have a table in my database with 5 columns (ID1 to ID5) and just one row. I'm trying to bind a comboBox, to show ID1 through ID5 in the combobox when my form loads. I have a dataset and tableAdapter's made for this already. I just want to know how to bind a combobox to those ID values.
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.
I think my question is discriptive, or as Microsoft in the Documentation for Data Grid the question is, How do I have a combo box column display a sub set of data based upon the value of a different combo box column?
