How do i make sure that the changes "done" by a user interacting with a DataRepeater control are reflected in the corresponding database source table? I have used DataRepeater in VirtualMode, do I have to supply my own code that will "actually" make corresponding changes to the actual tables, or is there a way of "configuring" or "binding" the controls on the DataRepeater to the "dataSet" so that the changes made by the user are reflected automatically in the underlying table? Whatever I have tried so far has yielded no results; whenever i edit the data on the control, the actual data is not updated. I attach a file showing the only events under which i have put some code: Load event of the Windows form, and the ItemValueNeeded event of the Repeater Control.

why my code isn't deleting the selected row in my ListView from my SQL table? it says it works fine in run time and removes the seleced row from the ListView but when i restart the program its there again.
Obviously this is because my code isnt actually deleting the data from the SQL table but i cant work out why not? the code for my delete button is as follows
Private Sub btnDeleteTask_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeleteTask.Click Dim delete As DialogResult = MessageBox.Show("Are you sure you want to delete this customer?", "Delete Customer", MessageBoxButtons.YesNo, MessageBoxIcon.Warning)

View 3 RepliesI have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

View 2 RepliesI have been trying to create a listview in detail mode which has 2 images (a light is on and one with the light off which represents a boolean value) I have gotten some code which populates the Listview during runtime but i have tried various ways to get the images into this without any success, google has been particularly useless and most examples seem to involve creating an array for each row(great if you have all the data in the first place, my project will perform like a log, it will show an Id, a Name and then 2 colums which should have on/off icons in them.
This is my sample code which works by creating a ListViewItem, adding the items for the row and then adding it. When i did this on my project however it showed nothing in the view (presume i need to refresh it after each add?)
