With a DataGridView bound to a bindingsource, which is filled by da.fill(ds) . How do I go about deleting selected rows when the UserDeletingRow event is fired? I've used the following code in the event:
Dim dsEmplTran As New DataSet
daEmplTran.Fill(dsEmplTran)
dsEmplTran.Tables(0).Rows(dgvEmplTran.SelectedRows(0).Index).Delete()
Dim cb As New SqlCommandBuilder(daEmplTran)

View 2 RepliesI have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
View 2 RepliesI have a List of an object, set to DataSource of a BindingSource, set to DataSource of a DataGridView. Then I added a DataGridViewButtonColumn which I want a click to remove that record from the collection. So I simply call collection. RemoveAt (e.rowIndex) from the DataGridView CellClick event. However this produces an IndexOutOfRange Exception; "1 does not have a value"..
So is happening here? I have maybe a vague idea, but would like to understand exactly which events are failing etc.. and what do i need to do to perform this action properly?
EDIT: This seems not to happen if I use a BindingList.. But when using a List, I get this problem..
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

I am trying to develop a scheduler for my workplace for which I am using a datagridview. The data displayed in the datagridview is bound to a SQL server database.
I need to be able to drag and drop rows so that the any job with a high priority and a nearer deadline can just be dragged from anywhere in the grid and dropped to the topmost point in the grid. I don't mind using two buttons (up and down) to do it either. But I am not able to figure out a way to do it.
How would I delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If I dont delete the successful rows then I will have multiple inserts of the same dataRow and we dont want that! And if I don't move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic I am trying to perform at the bottom of my code, right after I insert into the database.
Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click
'Function declarations
'Object declarations
Dim localOutputServer As SQLServer = Nothing
'Variable declarations (Form)

i am working on my first database program. i believe that I am almost finished, except that i have a remove button like i would like to remove just a single selected row both from the datagridview and the actual database. this is just in case any information is entered wrong, and also to delete all the entries i put in just for testing purposes. the only problem im having is in updating the database after removing the row from the datagridview

I'm loopiing through a datagridview and I want to get the selected value in a combobox, not the bound column's value. (I'm putting the contents of the dgv on a Word document.)
For icounter = 0 To Me.ConversationTblDataGridView.RowCount - 1
range.Text = range.Text & Me.ConversationTblDataGridView.Rows(icounter).Cells("PersonID").Value <-- I want to change "Value" so I get the displayed value, not the person's id
range.Text = range.Text & CHR(13)
Next icounter
It will not take .DisplayMember or .SelectedItem and .Selected returns True of False. Can anyone tell me how to get the name that shows in the combo box instead of the id number?

This code seems right but its not working. It's giving me an "Index out of range" error. If I change the upper bound of the loop to "(Count - 2)" the code works, it just deletes all except 1 selected row. So can't figure out why "(Count - 1)" doesn't work.
I am having trouble with multiple selected rows in a DGV. I have the following line to test how many rows have been selected.
Dim NoOfRoomsSelected As Integer = MonthDGV.SelectedRows.Count.ToString But each time the value comes back as 0.MSDN says : The SelectionMode property must be set to FullRowSelect or RowHeaderSelect for the SelectedRows property to be populated with selected rows.I have this set to RowHeaderSelect.
I would like to copy only the selected rows, but not all cells, only the ones I set in the sub, from one datagridview to another datagridview.
