VS 2008 Datagridview Or Listview Of Displaying SQL Database?
Aug 24, 2009
Well, just struggeling to decice on which would suit my situation best. I am developing a simple app to show a log of radio messages. Should I display these in a listview or in a datagridview? What is the actual difference?
I had done this by using the query builder (in VS Studio) but soon found out thay I gain no points by doing it this way as I am not using any code. I have tried to adapt the code I had to insert data into my database, just changing the SQL sintaxa and some other bits, but it is not working yet. Well, it gives results, but I think it is still geting the results from the query I had built using the query builder. Here is the code I've got so far:
Public Class Form2 Private Sub btn_search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_search.Click Dim str_search As String = txt_search.Text Dim str_dob As String = txt_dob.Text
I have a list view control and for each item I set to display an icon it will change the icons for the other items that already have icons, to the most recently added icon.
Here is my code.
vb.net Dim ext As String = Strings.Right(e.Item.Text, 4) Dim fileandparam As String = IconsInfo(ext).ToString
displaying it into Datagridview while inserting & deleting records in runtime..I insert records it into database using Access and delete but the datagridview not changes or update.my question is how can i update the datagridview while inserting records and deleting records.[code]
I have database like this [URL]but I will need to display only certain columns, which will depend on which user has logged in. Each user will have a unique ID, and so I want that that datagridview would only display the rows, which are for him, well have his ID, so that he couldn't see other users information, but only the one associated with him.I also need to output that user's forename and surename into label, it is stored in the database.
I want to be able to use this program to filter through a list of doctors, and based on what doctor you select, only show the patients who see that doctor.Here is what I have so far, the database has a column with just the doctor names so I thought I should be able to filter it by that and show the patients, but none show up. I don't get an error and it seems to refresh, but nothing ends up in the schedule.
vb Public Structure ScheduleOwner Dim _doctorname As String Dim _description As String
[code]....
Actually I just realized I don't think I loaded the data from the database as the form loaded. I tried doing that, but get an error where I called for the data to be loaded. I added the code where I try loading the databases."No value given for one or more required parameters."
I've been asked by a local window cleaner to design a small utility that can display a grid of customer data, sort them, and then export it out as a formatted .txt or rtf file.
Private Sub DisplayList(ByVal CusRef As Integer) Dim ConnectionString As String Dim SQLString As String Dim TitleString As String Dim conn As System.Data.OleDb.OleDbConnection
[Code]...
So that works, but how do I display multiple things, CustomerID & CustomerName on the same line?
I can't get it going, it only puts my CustomerName under the ID
I have recently built an N-Tier app using VB.Net 2008. The application is based on Beth Massi's tutorial at [URL] I am trying to incorporate a datagrridview control on a Parent form - one parent (father and mother) to many children. For example,
I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code , Dim dtParm As DataTable = MyDataSet.tblParameter Dim dgv As DataGridView = Me.dgvResultNum_DataGrid
I used the following code for retrieving a column items from access table and displaying it by using list view and it work perfectly, the problem now is that I need to add another column items to the list view ... but how? I displayed the two columns with their headers but the problem is retrieving the items for the second column.
This is the code that I used for the first column: ListView1.Items.Clear() Dim comm As New OleDb.OleDbCommand("select * from TEACHER", cnn) Try cnn.Open() Dim datareader As OleDb.OleDbDataReader [Code] .....
I have a problem with displaying output in listview in windows7. I am populating listview colum using OleDbDataReader from database which has value in string as "1,2,4,6,8,9,10" etc. But when I displays it in listview it appears as "10,9,8,6,4,2,1" i.e in opposite order but only in windows 7 not in XP.
on my application i have a username and password form that saves the username & password It's not meant to be secure, and it writes to a text file displaying as so
Private Sub cmdPostAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdPostAdd.Click 'Add new username and password
[code]....
This all works fine, but i have no idea how to reload this information when the form loads.Obviously it needs to read the string, the seperate the username and password.also is it possible to password char the password section in the listview? at the moment it can be read.
I have seen listview controls before that do not show any type of ID. (ie: Items in an order). So when I delete this row, how does it know which row to delete in my database? There could be many rows with the same exact data but each belonging to a different order. Would there be a hidden column with the record ID in it? If it is a hidden column, how would I go about this?
I've used this method for returning id's for ComboBox's and Listbox's:[URL]
My book uses Console app to display the result of a code but I prefer working with Windows forms controls. translate the code below so that it displays in a ListView or ListBox instead Console? Where do I find tutorials on how to use ListView/ListBox?
Dim ds As New NorthWindDataSet() Dim tblCustomers As NorthWindDataSet.CustomersDataTable = ds.Customers Dim rowCustomer As NorthWindDataSet.CustomersRow
This is my code in VB6 used for displaying data into listview using ADODB.recordset. converting this code into VB.net?. So I could load data into my listview easily.
Sub ListViewAdjustColumnWidth(LV As ListView, Optional AccountForHeaders As Boolean) Dim row As Long, col As Long
I have a ListView capable of displaying files in all available views (Large Icon, Small Icon, Tile, List, Details). Now I am wondering how to properly use the SmallImagelist and LargeImagelist for the small and large icons...the ListView is actually a modified listview (inheriting from ListView), using a modified ListViewItemCollection.In this custom ListViewItemCollection I use the Add override function to add a few details to my ListViewItem:
vb.net Public Overrides Function Add(ByVal value As System.Windows.Forms.ListViewItem) As System.Windows.Forms.ListViewItem Dim file As clsTexture = TryCast(value, clsTexture) If file IsNot Nothing Then
[Code]...
I realize it is a pretty complex post to read and will probably not get very many answers, but I really want to make the most of my Listviews...Of course, one work around is to just always use the LargeIcon which then gets scaled down automatically when the SmallImagelist is used but I am pretty sure there are icons that are very different in Large or Small view...
Okay, I've made a local database now and everything is okay. But I don't want the normal data grid view, I want to display the information in a list view. How can I do that? Do I have to make some sql queries or something?
if this question has already been answered many times, but I am new to VB and I don't really understand any of the examples I have found by trying to research this topic. I am using VB 2008 Express Edition. My List View is called listView.
I have a list of movie names in a list view. The user clicks a button and the posters and names are displayed instead. I want to be able to change it back to the list again. The problem I am facing is the size of the rows stay the same as the pictures when there not even there, the text alignment isnt fully to the left either. Is there a way to return the listview to its original state?
I've tried the following code but it doesn't delete and no error message received.
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click Dim Station As String = "" For Each sItem As ListViewItem In lvList.SelectedItems
