I have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I'm new to vb.net and I have what probably is a simple question, but one that I am stuck on. I'm trying to add a single item to a ca combo box at run time. For example, a user selects a category from the first drop down box at run time, say "Admin", I want to add a single item to the combo box below it: Not applicable.
I want to adding checked item from checkedlistbox to my combobox, but i have a little problem here.Combobox only show 1 item last checked.This is my sample code.
If CheckedListBox1.CheckedItems.Count <> 0 Then For i As Integer = 0 To CheckedListBox1.CheckedItems.Count - 1 cbCheckedItem.Text = CheckedListBox1.CheckedItems(i).ToString Next i End If
In the form below you see how the initial selected item is the first record of the table.. these controls are bound.. I want to initially show "Select one" in the combo box or nothing at all and the other controls not to be bound until an actual item is selected in the combobox..
I'm currently trying to add all the sections of a specified .ini into a combobox.[code]Now that's my section in the .ini, but it's scrambled and placed into multiple lines. I just want it on a single line as said in the .ini.Does anyone have any idea how to get values between brackets "[hi]" and place the value between the brackets into the combobox items?
I am searching a XML file for <Asset_Number> and then adding all children to DataGridView1, i can search but i dont know how to add item to the DataGridView Also my datagridview columns are created from a txt file

I'm using a comboboxcell in a datagridview with the combobox autocompletemode set to SuggestAppend.When I enter the cell and start typing, the autocomplete window pops up. When I click an item in the autocomplete list, the cell value is set and the cell exits edit mode. This has the same effect as selecting an item with up/down arrow keys from the autocomplete list and pressing the enter key.)
I want to copy that behaviour when an item is selected from the combobox dropdown list.E.g. if the user clicks the dropdown arrow button to open the dropdown list, then clicks an item in the list, the cell value should be set to that item, the dropdown should close, and the cell should exit edit mode.I've tried adding a handler to the combobox mouse click event, but the combobox only seems to receive that event if the main part of the combobox is clicked, but not if the mouse is clicked somewhere in the dropdown part. I don't think this matters if the combobox is used in a datagridview or by itself. how to capture a mouse click in the dropdown part of the combobox?
actually i have 3 fields in database which are Sid Fee status what i want to add combo column in field [status] with two option PAID or UNPAID which a user can select and update it .i am all clear with filling the datagridview from database and updating but only problem is adding a combobox in third field that is status.
i tried it with this Dim combo As DataGridViewComboBoxColumn DataGridView1.Columns("combo")
Has anyone here tried putting a combobox to a bound datagridview? The selected value of the combobox will depend on the value of the corresponding column in the database.
I have a datagridview. When the user clicks the edit button, the application fetches the records from the database and binds it to the datagriview. But I want to show the Gender Column as combobox with selectable 'Male' and 'Female' values.

So am back again with dattagridview and comboboxes...sorry for the troubless.. Now let me come to my scenario aka problem..I have 2 dataviewgrids in my WINDOWS APPLICATION FORM (VB.net).The first grid populates some data from the SQLSERVER 2005 DB.When I click on any cell of the first grid, my second grid shows up and populates with the data corresponding to the cell which I have clicked in the grid 1.This is working perfect and so far so good.In the second grid I have 3 combobox columns and some textbox columns..The three combobox columns in this grid are also populated from the DB only usng datasets and datasource.In the first Combobox Column if I select one value, then the corresponding values are filled into the other textboxcolumns.This is also working good.The other 2 comboboxcolumns are also populated from database using different datasets..
Am about to add a master data ( i.e data into the first grid).it got added and after that a msgbox pops up sayn u must add data into the second grid as well.so the user is adding the data in the second grid.(all works except the new requirement).he added something into the first row by selecting the comboboxcolumns and also editing the other columns in the first row.(he havent saved this row.This will happen when he clicks the save button in the form not in the grid)he goes into the second row .Now here he should not see the item from the combobox1 which he has selected in row1.
I am using a DataBindingSource to connect a DataTable to a DataGridView. Everything was working fine until I added a ComboBoxColumn
Dim ReasonColumnIndex As Integer = dgvData.Columns("Reason").Index Dim ReasonCombo As New DataGridViewComboBoxColumn With ReasonCombo .Name = "Reason" .Items.Add("BREAK")
I 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?
The user picks x amount of scenarios from the combobox, and x amount of columns appear in the datagridview. If the user changes the number of columns from x amount to y amount, the columns should be added/removed respectively but currently when y amount is chosen x amount of columns are in the datagridview.
I'm not sure how to do this, I've tried using an IF statement under the .SelectedIndexChanged event but the code adds columns until it reaches as high as it can go, then pulls an error saying too many columns.
I am using this to populate column1 combobox from a text file and it works fine.[code]I tried to add a number range using this to populate columns 4 and 5..[code]The number range populates the combobox(CB) fine but when i select a number from the CB it causes a error and selects the first item, the error loops evertime the mouse hovers over the CB..[code]
For Each Proc as process in process.getprocesses Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?
I have a combo box with "yes" and "no" with i select Yes i want the label2 to change the text to "yes" likewise with "no"
I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.
Public Class Form1 Dim aa As String Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
i have a combobox containing countries name and their codes like INDIA:CNT001 then i have a textbox that store the code of country i.e CNT001(fetching from database) Now i want to match that code with the combobox code so that the combobox is set to that item when i click a button. i m using vb.net and sql server as database.
my program downloads into a combobox every item(line) that is in a text file located on a server. Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)" - one that will allow the download in the combobox only the item ending with "a)" - one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear() ComboBox1.Items.AddRange(lines)
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.
i want to scroll with my mousewheel from first item back to last item and scroll then scroll more back.to scroll up from last to first i have with the folowing code but how to do it backward i dont know.

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'm trying to make a program that adds a menu item when right clicking files.I got a C# code here:[URL] and converted it to VB. It's working perfectly but the trouble is, it adds a menu item to folders and not files.
These are the registry entries i added:
Private Const MenuName As String = "FoldershellNewMenuOption" Private Const Command As String = "FoldershellNewMenuOptioncommand"
I am using ASP.NET with VB.NET as background code. I have 8 ImageMaps in my webform Estimator.aspx.Each ImageMap represents a car part (Front Bumper, Rear Bumper, Mirror, Hood, Sunroof, DoorShell, Headlights, Tail lights) and I have a dropdownlist ddlChosenParts. When the user clicks on any of the 8 ImageMaps, I add the PostBackValue to the dropdownlist ddlChosenParts.The problem is that if the user clicks on the same ImageMap twice, the PostBackValue is added twice.I want to check if ddlChosenParts contains the ImageMap's PostBackValue and if it already contains it, do not add it again. That means that if the user clicks more than once on the same ImageMap, it's PostBackValue is only added once in ddlChosenParts.I have this code but i'm getting an error: Value of Type String cannot be converted to ListItem. [code]
