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.
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.
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")
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]
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've this very stupid litle problem. I want to populate a combobox with numbers ranging from 00 to 99. But when I ad them with a loop as an integer the first ten numbers apear only with one digit.I wonder, how can I ad a second digit to them like; 00, 01, 02... and so on without me typing the whole list?
I'm trying to implement a combobox that will drop down and give a list of things that the user can select via checkbox so that they can have all, none, or some of the items selected/implemented in the program. Through some research, I've come up empty handed. I found a few tutorials that dealt with tons of class files, which I'm not really familiar with, didn't understand much, and then didn't work. Who would've thunk it right?Anyway, i tried just adding the checkedListBox as a control to the comboBox and it would disappear from the form as if it had been added, but wouldn't show up from the comboBox drop down menu..can anyone tell me how I can go about doing that?
In VB.Net for an ASP project I was able to do the following:
Dim Item As ListItem While DataReader.Read Item = New ListItem Item.Text = DataReader.Item("CustomerName").ToString Item.Value = DataReader.Item("CustomerNumber").ToString Me.lstCustomers.Items.Add(Item) End While
However in a VB.Net Windows Project it won't let me duplicate this.
I need to display the CustomerName but return the CustomerNumber of the selected customer
I am also adding the items in code because they are changing based on changing values.
I am creating an application install program, but one of the main things i cannot get working is the combobox, this is a drop down list of all my applications that i have put in there. I was wondering if there was a way you could tell the combobox to look at a directory or share and list the names of files within it? So, for example i could place 5 programs inside a share or directory then when i run the program and the click the drop down combo the 5 programs are listed and then i can click and install this program. Also then if i add/remove any programs it also removes it from the combo list.
i am having 11 comboboxes and 11 tabpages in 1 tabcontrol each tab page having one combobox.i kept the name of combobox like combobox1,combobox2,combobox3.....and so on also there are other comboboxes in tabpages but they are of different name i had also kept the tag property of combobox from 0 to11 for each one now what i want to do is add the same item in all comboboxes for that i wrote code like:-
dim combos() as string=new string("A","B","C"....) dim tp as tabpage dim cnt as combobox for each tp in me.tabcontrol1
[code]....
but this displays an error syntax like:"expression is of type System.windows.form.tabcontrol,which is not a collection type." i just want to add same items in combobox of each tabpage ..
Not too familar with the propertygrid control.But I have two comboboxes that need to be added to it from my.settings. How do i setup both My.Settings and then link it into the propertygrid?
The dropdowns will be named "Location" with 5 values, and the second called Hourly/Salary with 2 values.
This would be part of my larger application where the user selects these values and then logs in.
Is there a way to loop through each constant in the ControlChars module programatically? I want to add each of the enumerated control characters to a combobox control.
Well basicly I have been trying trial and error, and im sure this is a very simple fix, but how would I populate a ComboBox with information from My.Settings using VB.Net.
When I populate a combobox with items that have a line and text drawn in the DrawItem event, only the line image for the first item in the list appears in the drop down portion of the combobox. The other items (index>0) shown in the drop down portion of the combobox do not contain an image of the line, yet each item in the list does contain the designated text. The correct line image does appear when the user selects an item and the drop down portion of the combobox is not visible. How can I get the line image to appear in every item of the combobox when the drop down list is activated?
Public Class Form1 Friend WithEvents ComboBox1 As ComboBox Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Me.ComboBox1 = New ComboBox With Me.ComboBox1 [Code] .....
I have to add item "Final Grade" to my cboQuarter. The thing is, my cboQuarter already has a datasource and I can't add the item "Final Grade" during drop-down. The error says, "cannot modify or insert (can't remember word by word) when it already has a datasource."
I'm using ms access 03 to fill a datagridview no problem. I have 4 fields(id, first, last, points), but I just want to fill one in a combobox I have. Here is what I'm using to fill the datagridview:
Dim con As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and SettingsPC #6My Documentsstudent.mdb") Dim sql As String = "Select first,last,points from student" Dim oledbAdapter As OleDbDataAdapter Dim ds As New DataSet [Code] .....
How could I get a combobox to just display just one field, like idk if I'm explaining myself correctly, like a SQL statement look like this: Dim sql As String = "Select first from student" but just for my combobox.
I can't figure out how to refresh the combobox on my main form after I have added or deleted an item to the table that populates the combobox. I use a separate form to add, change and delete items in the combobox table. I have tried different suggestions that I have found on the subject on the web. Nothing seams to work... Here is what I have right now that does not work.
I am making a program and in the program I give the user the option to add Custom Items into the Combobox. To make sure that the Custom Items are still there when the program is restarted I use this code in the form load
Dim customcarrier As New IO.DirectoryInfo(Application.StartupPath & "CUSTOM") Dim carriers As IO.FileInfo() = customcarrier.GetFiles("*.txt")'gets all the custom items in the directory Dim carrier As IO.FileInfo
[code]....
The problem is that the program adds the whole filename with the extension to the Combobox. Is there any way I can exempt the last 4 char (.txt)
