im trying to make a combo box that shrinks as you type
Private Sub ComboBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles ComboBox1.KeyDown
ComboBox1.DroppedDown = False
I have a combobox which I called Combobox1, and it gathers a bunch of names from a database.My problem is I can't seem to figure out how to be able to type in the combobox and have the combobox drop down and start to find the name you are typing.I start typing BS I'd like it to display the BSmith for me to click on it and it would select it. This works if I click the drop down arrow, but I don't want to make my users have to click the drop down arrow to make it work. [code] This was working perfectly until I clicked on the drop down arrow then I had two boxes going at once.
I am unable to get the toolstrip menu item to delete or remove a yacht type, been working on this for a few hours now and still have had no luck.

Now I need to roll through the rows to validate and insertt the records into the database. I cant seem to access the ValueMember property. I have set a a looping structure and want to access the ValueMemeber property. I can get a property called Value, but it seems to be the DesplayMember value. How to access the Valuemember?
I am using Access 2007 as an automation server for a custom form in Outlook 2007. I am trying to use the records in an Access table as a rowsource for a Outlook combobox. I have been debugging it quite a bit; I can tell that I successfully grab a recordset and can tell that they are the correct values. The only problem is when I try to add an item to my combobox (cboCategory).I checked the properties of the additem function and it expects a variant, so that's what I give it. However at runtime, it gives me a type mismatch error.

I am working on Combobox in VB.NET08 The Combobox have list of Data.The Combobox Style is DropDown.Assume that i set a list of Countries in the Combobox.I need when i type on the Combobox that corseponding data should be heighlite in the list.Means if i type with "A" letter on the Combobox , shows all countries which statrs with "A". and again if i continue with writing 'A' and write 'U' then corresponding country names should be show in the list like 'Australia', 'Astria'.Here list in the sense not any other control , list means in the dropdown list.
I have 3 controls in my Form.Two Dropdowns and one textbox.My task is if i select a value in one Combobox then the related text should be display in other two controls.Ok I wrote a code in "SelectionChangeCommitted" event and now i am getting the values correctly.
This is my first web-based application using VB 2008. I had no idea where to start so I just chose the 'Wpf Browser Application' and started adding the controls on the form and naming them the same as I would do with a normal non-web-based vb app. I ran the XBAB file under bin/debug using IE and the form showed up but I couldn't enter text or anything even though the textbox was set to enabled?
This is the code Imports System.Data, System.Data.OleDb Public Class Form1 Public CON As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source =" & Application.StartupPath & "\bible.mdb") [Code] .....
I got that Error for data2.Fill(ds1, "Bible") Data type mismatch in criteria expression the combobox1 value is numbers
I tried this code Dim sql1 As String = "select distinct ChapterNum from Bible where BookNum ='" & Trim(ComboBox1.Text) & "'" And this code Dim sql1 As String = "select distinct ChapterNum from Bible where BookNum ='" & Val(ComboBox1.Text) & "'" And it still got the same error.
Combobox collection from -3 to +3 The goal of the message is to warn the user that the systems only covers +- 3 timezones, if he types in for example +4 or -4, he gets the message (by the way: how to protect the system if he types for instance a character?)
When I run the application: 'Unhandled exception: Cast from string "click" to type 'integer' is not valid
Private Sub ComboBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)
I have the following code which is not working, giving an error Conversion from string "" to type 'Double' is not valid.What am trying to do is if the shown value on the combobox is empty then set the two textboxes to empty strings.
If cmbactiveproj.SelectedIndex = "" Then txtclientOrgnw.Text = "" txtProjectID.Text = "" End If
So would it be possible that the problem comes from of the "time bit" : "00:00:00"?if, so is it the parsetime function which would allow to take into account only the time bit value of the combobox?
I've come from a Assembler and C/C++ background, so I understand the concept behind reference types versus value types in vb.net. Also, I've read Jon Skeet's article regarding references and value types and I understand all of that. My question is: How can you tell if a given type is a reference type or a value type? Is it simply that all integral types (ints, floats, etc.) are value types and all classes are reference types? (If so, where do strings fall?)
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?
I have a combobox..... When a user clicks on the list inside the combobox my webbrowser opens to the selected items website.how to make the combobox go back to the original text of the combobox?
Example: Combobox list ---- Select Item ---- Royals Mets
[code]....
When the user see's the screen the ---- Select Item ---- is visible. When a user clicks a teams name it opens the teams website and the name stays in the box. I want it to go back to ---- Select Item ---- immediately after they click a list item.
Is there a way to update source combobox to printer combobox selection?So going from printer1 to printer2 the source will update according to what that printer has to offer.
