I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

I need a way to read an xml file into a datagrid without using a dataset. I realize this is probably the accepted procedure, but it forces me to change a lot of existing code if I do.

I have tried googling so much that I have given up trying to look. I am trying to display a dataset in a wpf datagrid. After that I am going to need to display the individual column value in textboxes. I can then change the value in those textboxes and pressing, say, a commit button, to commit the changes to a database. Here's the code I have so far.
Dim con As New SqlConnection
Dim dbConnString As String
Dim ds As New DataSet

I'm populated my datagridview with data from my database - directly coded to update. I now want to export this data to excel or .csv file. I have found out how to export it from a dataset but not a datagrid. How can I populate a DataSet from my DataGrid? [code]

My problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here. I am using Visual Studio 2010 and attempting to create a WPF application. As you can tell from the code I am very new to this and any suggestions for improvement will be most welcome. I can see that the dataset is populated ok via the visualizer, I have a datagrid 'dgBOM' which I want to display the results. A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.
Code:
Public Sub Connect()
Dim cn As OleDbConnection
Dim cmd As OleDbCommand
Dim dr As OleDbDataReader

I have a datagrid that I use to display data from a SQL 2000 table. I am trying to write back any changes the user makes to the datagrid data back to the original table but don't know the proper method to do this.
Here is the code that populates the datagrid:
Dim TheDatabase As System.Data.SqlClient.SqlConnection
Dim ConnectionString As String
Dim cmd3 As New SqlCommand
Dim Adp3 As New SqlDataAdapter
[Code]...
I could use some suggestions on how to code the write back command that will allow the user to change the data in the datagrid and have those changes be written back to my tAdjustment table.

I am binding a dataset (dsTest) with a table called "TempResult" to a datagrid (DatagridView1).The purpose of the datagrid is to display test labels (set elsewhere in the software) and to allow the user to enter results into an empty column titled results.To achieve this I've filled the dataset with the required test labels then added a column called "Result" with a default value of 0.00.The user can enter numbers into the "Result" column on the grid then click a button "ADD" to update the changes to the datatset,When I first open the form the datagrid shows the correct information and any changes made to the Result column are updated correctly - all is well.
Private Sub Add_Results()
Dim ResultColumn As DataColumn
Dim Rows As Integer
Dim i As Integer
[code]....
If I close the form and open it up again (i.e. the user wants to add more results) the datagrid shows the results entered the last time the form was use and any changes made to the grid are not updated and the form won't work again until the software is reloaded.

It was written in vb6 and im trying to rewrite it in vb.net. I've completely stripped the program down from all the unneeded fancy addons and now just have the needed code to run it. The program retreives the records, but does not populate these records onto a datagrid.
Heres my Form code (Form1)
Imports ADS_SQL_TEST_VBNET
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]...
I think the problem lies within the LoadDataBound() Sub routine, but I can't say for sure since I was unable to fix this myself.

I consider myself a very patient guy with a whole lot of determination to get things working within say, a program i'm working on. However, I feel that I am only wasting precious time that I could be using to actually gain knowledge in something rather than hitting my head against a wall accomplishing nothing. It was written in vb6 and im trying to rewrite it in vb.net. I've completely stripped the program down from all the unneeded fancy addons and now just have the needed code to run it.

how to move current record in datagrid, i mean when i press Next record button then datagrid's data (table) also should move to next record or when i click any record in datagrid, then the current record of dataset also should move to clicked record of datagrid, so that i also may see datagrid's clicked record in textboxes in short i want to use default feature of vb6's ado control, when we bind datagrid with ado control, it worked autometically, both data grid and adodc wer connected each other at a time, so that moving next record also apears in datagrid.

I have a windows form with a datagrid and a dataset and some textboxes.I have a button that populates the textboxes with the selected row from the datadrid. That works.The user then makes changes to those text boxes.Now I would like to update the dataset with those new values and can not figure it out.If you could please give me some sample code,

I am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.
Here is my code so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Grabs data from excel sheet and stores it in datagrid.
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim con As New OleDb.OleDbConnection

Today i have been checking out the concept of datasets and i like the way they work except for a minor issue i have with it.The following code should get a databasetable and put it in a dataset and return that set to the user.[code]I submit the table name and it will select it, read it and fill the dataset with it, then return it. And it does exactly that once.If i try to re-read the same datatable it just returns the exact same dataset as the first time yet i am 100000% sure that i changed it .
