Populate Datagrid From Dataset WPF
Jan 6, 2011
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 am trying to populate a dataset from an XML file. Within the xml file are some € signs. However, when the data is read from the XML, the € sign is displayed as a ?. Has anyone seen this behaviour before, and if so do you know how to correct this? Below is a copy of the code i use to read the data from the xml file:
Public Function ReadExportFile(ByVal sFilePath As String) As Boolean
Try
msExportFile = sFilePath

I'm trying to populate a combo box with a dataset, this sort of works, but everything is just appearing on the same line. I think this answer might be to put the dataset into an array, then put the array into the combo box.
...problem is, I'm not sure how to do this! My code thus far is,
Dim usernameList As Array
'Retrieve usernames where player has available status
GetFilteredData()

I have need for a database in my latest app, i quickly realised it had been a long time since i last used a database and am in fact very very rusty on the subject. So i decided to create a simple DataSet using the designer, i created 2 tables as follows
Table 1 is Named Map and contains a 2 dimensional array each cell containing an array of object id's of anything in that cell, and a level ID.
Table 2 contains data about these objects ie size weight and a z-order, again referenced by an object id (matching Table1)
This i did with no issues, when it came however to actually populating these tables i drew a blank. Do i have to locate the database file and edit with notepad? I presume not. Maybe i have to use an external app like sqlmanager? I seem to recall from my past that i added table rows from within the designer but i cannot find this in 2010 express

This is a problem I have been trying to conquer for some time now and haven't managed to deal with. I've looked pretty hard on Google and so on, but most of what I find there is for populating a TreeView from a database. The closest I got was a bit of C# code for populating with a list of file paths. But unfortunately the result is individual roots & branches for each item.
What I'm working on is a message template tool where I'm trying to get the nodes in the treeview, which represents the templates, to populate from an XML file. I'm using DataSets for their simplicity of working with XML. Here's a basic example of the structure of the XML which is imported to the DataSet;
Code:
<?xml version="1.0" standalone="yes"?>
<Templates>
<Item>
[Code].....
So the path to each node will look like RootBranchName. I know this will no doubt require some recursion, but recursion is one thing I haven't fully grasped yet.

I am using Visual Basic in Visual Studio Express 2008. I am creating a form that works with an Access database which has five tables, though for purposes of my problem I will only mention two of the tables: Customer and Project.
The Customer table contains basic customer info, with a unique ID auto-number. The Project table describes relationships between two customers. There is a Primary ID number and a Secondary ID number, both of which correspond to an ID number from the Customer table. Any given ID number can exist as a Primary or Secondary ID, so if "Bob's Company" ID is 1, and "Fred's Company" ID is 2, there can be two projects, one having "Bob's Company" as Primary and "Fred's Company" as Secondary, and the other vice versa.
The user navigates through the Customer table by means of a combo box. They choose one customer name from the box, which populates a label with that customer's ID number. I have a View Projects button with the intent that once the user chooses the company, they can click View Projects and a DataGrid will appear which contains only the records from the Project table in which this specific Customer number appears (either as Primary or Secondary). So basically, with all that explanation, I'm trying to figure out how to get the View Projects button to take the CustomerIDLabel.Text and use that to populate the DataGrid.[code]...

I am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET.I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes. For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. So a grade 1 team can respond to emergency priorities of 1 and 2.A grade 2 team can respond to emergency priorities of 1, 2 and 3.A grade 3 team can respond to emergency priorities of 1, 2, 3 and 4.
So basically, if the user selects emergency priority of '4', then only grade 3 teams can be displayed. I am using two different tables in the datagrid. The datagrid is populating at the moment, but not based on anything that is selected in the comboboxes. It just displays a lot of duplicates of all the records in the tables. Here is my code so far (this code is on the search button click - I have already loaded items into the comboboxes on the form's load event):
Dim sqlConn As New OleDb.OleDbConnection
Dim sqlCmd As New OleDb.OleDbCommand
Dim sqlReader As OleDb.OleDbDataReader

I have a simple access database that a log record gets written to a few times an hour.
I'm trying to make a DataGridView that shows that data as it arrives.
My "Solution" is simple;
when a user clicks the view -> read from the database (fill the datatable) -> update the view.
Not what I dreamed of, but functional, if totally sub-optimal.
However, my "solution" is a dud, using fill draws every single record from the database, even if there are already 599 on screen.
Really, I just want fill the datatable once, and add new records as they arrive (or on click if needs be).
Bonus point if you can also explain another way (that isn't called so often) to hide the ID column, and change the header of column 1 (named DateTimeStamp) to TimeStamp.
Public Class FormMain
Shared dataAdapter As OleDbDataAdapter
Shared logTable As New DataTable("log")

I am creating an electronic display board using Visual Studio 2005, this will be an application using VB and not web based.What I am trying to do is use labels dynamicly and populate them from a dataset, Now there is a lot of labels on this board and to be honest the perfect solution would be to use a Data Grid View, unfortuantly I have to fit the information into a Custom Graphic that was created, hence the reason for labels.So obliviously I dont want to have to name each label and specify its information, for example:
Code:
Label1.text = MyDataSet.Tables(0).Rows(0).Item(0)
Label2.text = MyDataSet.Tables(0).Rows(1).Item(0)
Label3.text = MyDataSet.Tables(0).Rows(2).Item(0)
So I thought about something as follows but not sure how to get it work.Say I new I had 100 Labels Label1 to Label100.
Code:
Dim i as Integer
For i = 1 to 100
[code]....
Now the above doesnt work but it doesnt throw up any errors either.

I'm having a little trouble figuring how to do this.I have a dataset with a single table. Each row has the following fields ProductName, Version, CompanyName
The data might look like this
Visual Studio, 2005, Microsoft
Visual Studio, 2008, Microsoft
Office, 2007, Microsoft
I have already populated the TreeView with a list of Company names from a separate table. Now, what I want to do is to loop through my dataset adding a single node for each product under the appropriate manufacturer. Then under each product adding a separate node for each version of that product.

I am trying to build a DataTable to populate a DataGrid in VB.NET. The columns will be the username and then question from an exam. Each row will be the answers by user for each question.
So it would look something like this:
Username | What is your favorite color? | What is your favorite book?
-------------------------------------------------------------------------
Joe Blue The Hobbit
Fred Red The Road
[Code].....
That works great and gives me a table that has the needed columns, but I am stuck as to how and get each users answer and put it under the appropriate column.
I tried adding rows in the same loop, but that just adds all of the answers under the first column.

I want to populate a listview with items from datagrid view. I've been searching for solutions but it seems that all the scenarios I found were about populating listview with items from tables in database, not from another listview or datagrid view.
I'm trying this code:
For count As Integer = 0 To (DataGridView1.Rows.Count() - 1)
Dim row As DataRow = DataGridView1.Rows(count)
Dim item As ListViewItem = New ListViewItem(row(fieldfirstcol).ToString())
item.SubItems.Add(row(fieldsecondcol.ToString()))
ListView1.Items.Add(item)
But it doesn't work; it says DataGridViewRow cannot be converted to DataRow.

just would like to ask if it is possible to manually populate the datagrid in asp.net 2003 using vb.netwe usually populate the datagrid using this code, in this code what it does is it populate the datagrid base on your query , it's automated you can't edit or evaluate the data inside.
dataGrid.DataSource = ds
dataGrid.DataBind()
What if if I want to edit or evaluate the data inside the DataSet?

I need some suggestions on how to tackle this issue. I am fairly new to using ADO.NET and am running into difficulty populating a dataGrid.Basically here is what I want to accomplish:
a) on form open the dgvLOCATION populates with any records found in the database that match the customer ID that is displayed in a text box (the textbox will already have a value when the form opens)
b) when the value of the Customer ID textbox changes then the dgvLOCATION will change (I am already going to do this with a text changed event...I am just having problems with the query)
I am using VS Studio 2005 and connecting to an Oracle 10g database.I have also created a 'view' for the dataGrid since it will not any binding.Currently the dataGrid will populate will ALL database records on 'form open' if the field value of Customer ID is not null.
I am using the Query Builder wizard and when I enter the following I get an error.Select C_ID, ST_NUM, ST_NAME, CITY, RESIDENCE From CUSTOMER_LOCATION_VIEW Where C_ID = :TXTCID.TEXT
The error tells me that the query could not be parsed.

I am attempting to discover how I can populate a ComboBox with the data values already located in a data source that has been added to my project. I know how to use the ComboBox.Add method. I also know how to add individual value items contained in a manually entered array at design time using the For Each Next loop. However, I am unable to populate a ComboBox with all values for a field of a table in a data source that has been added to my project. I assume that I am unaware of some simple referencing step that will solve this problem.
