I tried to populate several ComboBoxes, but if I use databinding, the ComboBoxes all show the same value.Also, if I select a certain value, it also selects that row in the table, which I do not wish to do..

Creating A Reporting App That Pulls Information Off Of A Sql Database And Populates The Data In A Datagridview Control (DVG)?
Mar 31, 2011I am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs

OLEDB Connection - Pull Information From Three Different Database Tables And Compiling The Information Onto One Screen
Jun 9, 2011The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

Populating A DataGridView On-the-fly?
Nov 16, 2009I have a DataGridView which reads data from a custom (CSLA) list object. The dataset might have 100,000 records, and obviously I don't want to show them all at once because, for one, it would take ages to load.I think it would be nice if I could read the first (for instance) 20 records, and make it so upon scrolling to the end of the list, it reads the next 20 and adds them to the DataGridView.
I have experimented with various ways of doing this, mostly using a custom class inheriting from DataGridView to capture scroll events and raising an event which adds new records. I will include the code below:
Public Class TestDGV
Inherits DataGridView
Public Sub New()
[code]....
Though this (sort of) works, it can be buggy. The biggest problem was that if you used the mouse to scroll the DataGrid, it would get stuck in a loop as it process the scrollbar's ValueChanged event after the data was added. That's why I added ScrollbarOff and ScrollbarOn - I call them before and after getting new records, which disables the scrollbar temporarily.
The problem with that is that after the scrollbar is re-enabled, it doesn't keep track of the current mouse state, so if you hold down the 'Down' button with the mouse (or click on part of the scrollbar) it stops scrolling after it has added the new records, and you have to click it again.
Manually Populating A Datagridview?
Jun 10, 2009Historically I used Tek-Tips for stuff like this but I can no longer access my account there and they do not respond to form based mail. Maybe they got tired of the questions too :-)
I am not a student. I manage a 'large' network. Every now and then I need to roll up something for a specific task. Most of the stuff I write only sees my desktop so neatness and originality are not an issue.My current 'project' is throttling back a few of my users disk storage. I am not allowed to implement Quota's (Server 2003 infrastructure) so I thought the next best thing would be a duplicate file report. I purchased Folder Sized 4 which is a beautiful product (I have used it since it's humble beginnings as Bullet Proof Folders). The end users claim that the filename and date checks are not enough to prove a duplicate. Enter my idea.
I have cobbled together a MD5 hash generator from a function found out on the web. Now I want to send the results to a datagridview instead of my current disk files.I has thought that I could access the rows & columns like dgv.row(x).column(x) = "strFile", dgv.row(x).column(y) = "strMD5"Nope, hunting through the available properties did not point me to any likely candidates.
Again, if this is not the place for questions of this nature please let me know. I am not a programmer, nor am I in training to be one. I just toss little things like this together when needed. Importing a CSV file into Excell is working, but it seems rather lame to be taking so many steps.

Populating DataGridView Combobox Column?
Mar 26, 2009I have an unbound DataGridView control that displays a few columns of account data. The first column is a combobox that I fill with data from a dataset of names filtered by what's in a customer field on the form. When you click on a combo on one of the populated rows, the available names come up in the combo. But if the first click in the datagridview is on a new row's combo, various (incorrect) names appear. Only after you click on one of the populated row's comboboxes, does the correct data appear in the new row's combobox control.
I don't really understand why this is happening. I have been using the EditingControlShowing event to populate and add the combo to the new row, but it doesn't seem to be working very well. I hope someone out there has some ideas about the correct way to do this.
Populating DataGridView With Correct Data
Jul 30, 2011[VB 2008]. I'm trying to populate a DataGridView based on information in the Items in a ListBox (specifically, the file names without hypens or file extensions) and the content of the actual files. The DataGridView is supposed to look something like this:
IDNon-Hyphenated File NameFile Data
1. Some fileThe sky is blue.
2. Another fileThe grass is green.
The Items in the ListBox (lstFiles) look like this:
C:UsersUsernameDesktopFolderAsome-file.txt
C:UsersUsernameDesktopFolderAanother-file.txt
What is happening is that the DataGridView is being populated, but it looks like this:
IDNon-Hyphenated File NameFile Data
1 Another fileThe grass is green.
2 Another fileThe grass is green.
It's adding the second file's information to the DataTable twice and not adding the first file's information at all.

Populating The Datagridview Control Using Webservice?

I'm using visual studio 2005 and I have little experience using the datagridview control. In my webservice, I started the code that will be the datasource - should i be returning a dataset?

Populating DataGridView ComboBox Column During Runtime?
Nov 16, 2009I've got a window with multiple datagridviews. Each with data from a separate dataTable. All of which are part of the same DataSet. There are a couple of places where one DataTable has a field joined with the lookup dataTable from the dataset. For example a lookup table for LugSizes has a field called LugSize that is also it's primary key. Another table called Device Terminations has a field called LugSize to which the user can only select those values from the LugSize lookup table. I thought it would be as simple as using the Items.Add method for the combobox column whenever a new lookup table row was added to its own datagridview. Unfortunately, when I try to initially clear the items list, the data error event is triggered for every row.
Here's a sample of my code if it helps:
HTML
Private Sub FillLugSizeComboBox()
Try
If colDTLugSize.Items.Count > 0 Then colDTLugSize.Items.Clear()

VS 2008 ComboBox Selection Populating DataGridView?
Feb 7, 2012I have a form with a DataGridView and ComboBox, both of which are populated with data from an Excel spreadsheet, the source is unbound. My problem is in repopulating the DataGridView with data from another worksheet in the same Excel file when the user selects the corresponding value from the ComboBox. For example if they were to select January from the ComboBox then the DataGridView would load in and display the data contained on say Sheet2, selecting February would load Sheet 3 and so on. I am running Visual Studio 2008.
View 6 RepliesVS 2008 Manually Populating And Finely Tweaking A DataGridView
Sep 23, 2009I've been playing with a DGV. Let's say for my question here, I want a grid that is 10x10. I would like the font in each cell to be Arial 10 regular. Only one character will be in each cell (I'll use "M"). I would LIKE the cells to be 17 pixels by 17 pixels. But, if I manually force the column width to be 17, I get about half of my M and three dots "M...". I'm thinking this is a padding thing but as far as I can tell, everything is set to 0. See code and then more comments below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
With DataGridView1
[Code]....
Question 1: How can I reclaim some of what seems to be lost space around the cell contents so I don't have to make them bigger than they need to be? I'd like them to be 17x17 with the single character centered within.
Question 2: Do I have to manually set the height and width of each row and column? I'm thinking the RowTemplate setting but can't seem to get it to work.
FYI: This is a new project with a DGV dragged onto the form. All changes have been made programatically.
