Set The Binding To Update The Sql With The Changes Made By The User In A DataGridView?
Aug 25, 2009
I have created a form that contains a DataGridView with data from a SQL Database. After viewing, the user will want to update checkbox fields in a single column of the DataGridView This action needs to update the SQL Database. I have set the "ReadOnly" to false on all the columns of the form and placed an "Edit" button on the form which changes the ReadOnly Property to True on the Column where changes would be allowed. How do I then set the binding to update the Sql with the changes made by the user?
I have a manually created a dataset (dsPickingList) that I add data too as the user inputs data on a form. There is a datagridview on my form of which it's datasource is set to dsPickingList.What I would like to do is spot if a user deleteds a row from the datagridview and update the dataset (dsPickingList) as it is ultimatly this dataset that is stored to the db and printed, not the DataGridView.[code]This is why I need the action from the DataGridView to update the dataset
I can't get my binding source to update from a DataGridView
This is how I'm loading the dataset into the dgv:
vb.net Dim sFileName = filelocation & "Checks.xls" Dim connectionStringTemplate As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1""" Dim connectionString As String = String.Format(connectionStringTemplate, sFileName) Dim sqlSelect As String = "SELECT * FROM [Sheet1$];" Dim workbook As DataSet = New DataSet()
Im on project about database and I actually im facing 2 major problems.#1I made a form where the user can create a new record.Actually a new product like :
Public Class newgame'Dim cmd As OleDb.OleDbCommand = New OleDb.OleDbCommand("INSERT INTO clients(name,surname,address,phone home,mobile phone,e-mail,memo) VALUES (' " + TextBox1.Text + " ' , ' " + TextBox2.Text + " ',' " + TextBox3.Text + "','" + TextBox4.Text + "','" + TextBox5.Text + "','" +
With the DataGridView I'm used to just populate them with a list of some object, using the DataSource property. Now I want to just display properties from a single object, and I'm a bit confused on how to do it.. The object is updated through an API event, and I want to select some of the properties for displaying in the DataGridView, to look like this:.where "ValueX" is the name of the properties.Now, what would be my options for binding this to the DataGridView, such that property changes are automatically updated. Since an update also must invoke the control, does that mean I must reassign all bindings, or what logic is necessary in this case?
should I bind to an array, arrayList, stringList, dataTable etc? I guess I'm not sure which type of source will allow binding. Or if I should perhaps build the columns and cells of the grid and populate them "one-by-one" to the properties of the object?
I was wondering how you update a program made in vb.net. I know that when you click "Publish" you do a bunch of crap and it shows if you want your program to check for updates.
When I click on the Save button in the interface it executes the SaveData() steps. But I am being told that I need to update the date stamp on the Access file. How I would make this change?

I hope that someone help me , i have a form , a datagridview bound to datatable and a button named " Cancel "

I have numberic updown control in my app. There may be times when I want to programatically change the vlaue (in which case I don't want to ValueChanged event handler code to run). There will certainly be times when the user makes a change (in which case, I would want the event handler code to run).
I have a DataGridView in my VB.net Form. I need to make some rows invisible based on a value. As there is not GridviewrowdataBound, I am trying to achieve it as shown in the below Code
Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting[code].....
When I try to do this I am getting the Uncommitted new row cannot be made visible error.
I have a DGV bound to a data adapter. I have a button that loads a form with a reference to the DGV row. When the form is loaded, it has a TextBox to type a value, that modifies one of the cells of the row. When the form closes, the cell.value is properly modified, but saving the DGV doesn't save the new value of the cell to the DB table. I'm assuming this happens because the DGV hasn't had physical interaction. Also, this particular field is a password field, so the whole column is being hidden from the view.It seems that a DGV change is noted by physically clicking in a cell and it stores some data telling the adapter there have been changes. The thing is, this is done on a per cell basis, and only if the cell has been clicked. Well, this cell is hidden, so even though the value will be changed, you could never click or select that cell.Is there any other way to force the DGV to accept changes made to it from outside actions of just assigning the cell.value from a button click and not phsyically changing it in the DGV?
Is it possible to save into temp data a user made class? I have a class with many structures and each structure contains variables and im trying to add to my program a way to save the data of that class object with its structures and everything is that possible? I tried manually making some sort of save but its taking too long and proving way too hard for me. Is there a way to just convert it into some general object format and save the object? Is that possible can you just save undefined objects without having to create a format manually for that object?
I use a DataGridView to Add/Edit/Delete records from an Access database. Doing those 3 things is working just fine. When I try to update the database with the new Table data, nothing happens. I need to basically overwrite the table in the database with the data that was added, edited or deleted in the DataGridView. I opened the connection and got the table data like this
I am using SQL Compact Edition and have a textbox binding to a dataset. When I enter something in the text box and try to update the datasource I get that the column Code in the datasource cannot be null. The textbox has a value so why is Code null?
Dim CONN_STRING As String = "Data Source=" & My.Settings.AutoCallPath & ";Persist Security Info=false;" conn.ConnectionString = CONN_STRING Dim myCommand As New SqlCeCommand("SELECT * FROM AutoCallDataTable", conn) da.SelectCommand = myCommand
In my viewmodel I have the property implemented like this:
Public ReadOnly Property IsBeheerder As Boolean Get Return iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder)) End Get End Property
Then when I raise my PropertyChanged event in my callback method
Private Sub GetMyPersonCompleted(ByVal lo As LoadOperation(Of FunctieRol)) 'Init FunctieRollen ect. ... RaisePropertyChanged(Function() Me.IsBeheerder) End Sub
my binding does not update. However! If I implement a backend field like this:

I'm curently trying to get information displayed in a listbox from a selection made in a datagridview. For example a user selects an artist from the treeview control and it displays all the albums by that artist in the datagridview. Once a user selects an album all information for that album is displayed below the datagridview in either a listbox or listview control. I've tried dragging the conrols from the datasource and it' won't drag onto the listbox. What do I need to do to get it so that it will display album, artist and track information?
I have a MS Access database file that I can view with a DataGridView, but I can not save the changes made. User should be able to modify data, and when pressing the "Save" button, these changes should be reflected on the database. That is not happening.I know this is a common question, but I have read dozens of pages trying yo get this to work.

is there any working examples of implementing add/update/delete using the binding source?
i have a datagridview that has a bindingsource as its datasource and i am wanting to provide Add/Update/Delete functionality on the grid itself. Each record has a delete button which when clicked will remove the row and then add/edit is performed in the grid itself
the user then clicks a save/commit button that will then perform the nessecary updates on all rows
my initial plan was to have a copy of the data (iList) and then compare this to the contents of the binding source data to confirm whether to add/update or delete the record
also upon clicking the delete button i cant get it to remove the row from the datagridview. it thought i could do something like this...
Private Sub dgvDocumentTemplates_CellContentClick(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) If (e.ColumnIndex = 6) And (e.RowIndex <> dgvDocumentTemplates.Rows.Count - 1) Then
So i have that code in my xaml and the button gets filed with a list of string. Depending on what the users chooses on previous Usercontrol that item will be filed with differents items. The problem is if the user select one option at the first run the button will be filled correctly but if the user go back and select the other option the control doenst update and shows the same as before.. My english is not the best but i think i could made me understand! PS: the bindind on Button is to a readOnly property so i cant define it to Mode="TwoWay".. i took a look on the debug and the property ExportFormat gets updates with the new items but the usercontrol still displays the first option!!
I've created a custom control which consists of two radio buttons with their appearance set to "Button". This control is meant to act like two toggle buttons with an "On" toggle button and an "Off" toggle button. I have a public boolean property "isAOn" which is used to set the state of both buttons and I want to be able to bind this property to boolean values. I have imported the component model and set Now when I add this to a form for a boolean value in one of my classes it doesn't seem to update the boolean value of the class when I change the button pressed.
Here is the code:
Imports System.ComponentModel ''# <DefaultBindingProperty("isAOn")> _ Public Class ToggleButtons
I have been on a database project for a while now. I wanted to be able to make changes to my database using the update command of a Datagridview control.However, I have been faced with a series of unsuccessful outcomes.I want to do this how do I go about it?
