There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.
In datagridview .DataSource how about in listview ?
Is it possible to populate a listview with a dataset? I have a function that returns a dataset. Why im asking this is because my SQL is quite complicated and i can't convert it to a SQLDataSource..

How do i populate datatable with listview. . . .i have tried this code but it doesnt give the items that contained in listview to datatable. .
dt.Rows.Add(ListView1.Items("Quantity"), ListView1.Items("Description"), ListView1.Items("Price"), ListView1.Items("Total"))
When the user clicks an "Edit" button on my form, I want a box to come up which allows the user to edit a DataTable in a strongly-typed DataSet. What's the best way to do this?
View 2 RepliesI have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.

I populate a datatable from a database. The table is sorted by the first column.
Then I add some new rows to the table. After that I sort the table with pgds.Tables(0).DefaultView.Sort = "firstcolumnname"
The new added rows are listed after the originally ordered rows and not in the right order.
I'm making a questback in Windows forms (VB). I've succesfully setup the MySQL-database, and made connection with everything needed. I've also manage to populate a DataTable called tblAlt for the alternatives for the question.Then I try to populate each radiobutton with rows from the DataTable.Here's what I tried:

If tblAlt.Rows.IndexOf(row) = 0 Thenof the table).

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

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'm trying to populate an array from a dataset with only specific column using vb.net 2010. is there any code to populate the array directly or must i make the use of a query?
View 1 RepliesI'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()

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 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.

View 7 RepliesPart 1 of what i want to do is on the Load Event of my form i want to look at an excel worksheet and populate a data table with the data found in the first two columns of the worksheet.
Essentially column 1 is Descriptions and column 2 is pricing
Part 2 of what i need to do is that when a user selects a description from the combo box it populates a text box with the appropriate pricing.
After doing some reading into this all i have seen is some threads on how to use Jet4.0 to link and grab the data but it is my understanding that Jet doesnt work with 64 bit OS.
Nonetheless I need to figure out a way to accomplish my end goal and make it as universal a solution as possible (ie. i do not want it to only run on 64 bit or 32 bit machines)
