VB 2008 - problem updating datagridview

Hello everyone,


I'm stuck on a stupid problem

I have a datagridview where i add rows using array like this:
Dim srow() As String = {getIDprodus(cmbprodus.Text), cmbprodus.Text, getprodusforma(cmbprodus.Text), txtcantitate.Text}
griddetalii.Rows.Add(srow)


Next, i need to let user to modify the added row. So when user selects a row and press EDIT, a new form is popped out using this code:
Dim i = griddetalii.CurrentRow.Index
frmdetaliiiesire.cmbprodus.Text = griddetalii.Item(0, i).Value
frmdetaliiiesire.txtcantitate.Text = griddetalii.Item(1, i).Value
frmdetaliiiesire.StartPosition = FormStartPosition.CenterScreen
frmdetaliiiesire.ShowDialog()

In that form, the user can change the 2 values and after that, he clicks ok with this code:
frmiesiri.griddetalii.Rows(CInt(TextBox1.Text)).Cells(0).Value = cmbprodus.Text
frmiesiri.griddetalii.Rows(CInt(TextBox1.Text)).Cells(1).Value = txtcantitate.Text

In textbox1 i have put the index of the current row selected in grid


The problem is when i push OK, the applications crashes and i receive an error: INDEX WAS OUT OF RANGE

If the users changes the values from the same form, it's works. But changing them from another form crashes the applications

Can someone help me?

put a msgbox in there + check that cint(textbox1.text) is what you expect it to be

i did....
it says that index = 0 and that's corect, it's the first row from the grid. but i still receive the "INDEX OUT OF RANGE" error :(

i have made some things ...

underneath the datagridview, i put a textbox and next code:

vb Code:

Private Sub griddetalii_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles griddetalii.CellContentClick
                TextBox1.Text = e.RowIndex
    End Sub

but when i click the first row, the value in the textbox is 3 :|
why ?

i don't know why that'd happen.
maybe if you post more of your code or zip your project + post it, i might find it

here you go...maybe you can explain why....


i have created a new simple project, and i get no error when i try to update the datagridview from another form... it works perfectly with the same code....


ty man

i'll have a look at it later this evening (it's 8.15pm here now). just a guess though, is frmiesiri a child form, + do you have more than 1 instance of frmiesiri open at 1 time?

it might be that you load frmiesiri as form3 in your mdiparent form, so that is what you should refer to it as:

form3.griddetalii.Rows(CInt(TextBox1.Text)).Cells(0).Value = cmbprodus.Text
form3.griddetalii.Rows(CInt(TextBox1.Text)).Cells(1).Value = txtcantitate.Text

i'm an idiot :(

it worked then?:D

no, it didnt

when i write form3, it says that: form3 is not defined.

:(


LE: only one instance of frmiesiri is open at a time :)

ok try this (in frmdetaliiiesire):

vb Code:

Private Sub btnok_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnok.Click
    Me.Owner.griddetalii.Item(1, CInt(lblid.Text)).Value = cmbprodus.Text
        Me.Owner.griddetalii.Item(3, CInt(lblid.Text)).Value = txtpretunitate.Text
        Me.Owner.griddetalii.Item(4, CInt(lblid.Text)).Value = txtcantitate.Text
        Me.Owner.griddetalii.Item(5, CInt(lblid.Text)).Value = txttva.Text
    Me.Close()
End Sub

it says: griddetalii is not a member of System.Forms.form

vb Code:

Private Sub btnok_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnok.Click
    directcast(Me.Owner, frmiesiri).griddetalii.Item(1, CInt(lblid.Text)).Value = cmbprodus.Text
    directcast(Me.Owner, frmiesiri).griddetalii.Item(3, CInt(lblid.Text)).Value = txtpretunitate.Text
    directcast(Me.Owner, frmiesiri).griddetalii.Item(4, CInt(lblid.Text)).Value = txtcantitate.Text
    directcast(Me.Owner, frmiesiri).griddetalii.Item(5, CInt(lblid.Text)).Value = txttva.Text
    Me.Close()
End Sub

Object reference not set to an instance of an object.


:( :( :( i think i will soon hang myself



LE: i realize now, the problem is because i use MDiform :)

the test application i have used so far, i have added a mdiform, and i still get the index out of range error. damn mdiform

still alive i hope?

try this now:

OMG OMG OMG OMG OMG OMG OMG OMG

it works........

unfortunatelly, it's verry late for me and i have to go to bed to sleep few hours before i go to work.

man, i must admit, you're a genius. How can i rate you?

thanks alot, i hope somedays i will manage to help you too :)
