Nobody is going to reply if you post a question with this.

How about posting the update code and we can see where the problem is. For starters I would re-evaluate the whole order. Just updating/adding the one student would not "auto" update the rest of them. Post the code you use for the update and we can check or advise from there.

I am using:

<br />
foreach (DebtorDataSet.PaymentArrangementsRow row in debtorDataSet.PaymentArrangements.Rows)<br />
                                {<br />
                                    if (row.PaymentArrangementID != -1 && row.PaymentTypeID == Convert.ToInt32(paymentCategoryComboBox.SelectedItem) && row.ArrangementComplete == false)<br />
                                    {<br />
                                        row.ArrangementComplete = true;<br />
                                        row.ArrangementDate = DateTime.Today;<br />
                                    }<br />
                                }

but this is giving me the error:
'Unable to cast object of type 'System.Data.DataRowView' to type 'System.IConvertible''
I am not sure how to correct this.

Any help would be much appreciated please.

I'm not really sure about it, but because there is only one line where you convert something I would
replace

Convert.ToInt32(paymentCategoryComboBox.SelectedItem)

with

Convert.ToInt32(paymentCategoryComboBox.SelectedItem.ToString())

But in general SelectedItem is not from the type 'System.Data.DataRowView' so I'm a little
bit confused with it. But maybe that helps.

Many thanks for your reply.

Sill me realised that I needed SelectedValue instead of selectedItem to do the job.

What type is the SelectedValue?
If it's an int, why convert an int to an int? Just cast it.
If not, then you can probably cast it anyway.

I find the Convert class to be nearly entirely useless; try not to use it.

This question isn't really answerable is a forum environment. The description of everything you ahve to do would be a larger article or a small books worth. Far beyond the capacity of a few forum posts. All I can do is direct you to start researching the System.DirectoryServices namespace to get an understanding of the classes you're going to use to manipulate Active Directory. From there, you can come up with a design for your ASP.NET app.

Would you care to actually explain the problem and the code you're using or should we just guess at the million or so possible issues you have?

Problems with VirtualMode of the DataGridView

Hi Guys,

i need the NewRowNeededEvent of the DataGridView. So i set the VirtualMode Property to true.
But if this property is set to true, i need to set the cell value by myself, otherwise it vanisches if i leave the cell.

So i've tried to save the value - the cell is a ComboBox where i select a value - in the CellValidatinEvent.

But it doesnt work. The value property of the cell is not changing it is still null.

Here is some code that you can understand what i mean.

<br />
<br />
 private void aufwandDataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)<br />
        {<br />
            DataGridViewComboBoxCell cell =<br />
            aufwandDataGridView.CurrentCell as DataGridViewComboBoxCell;<br />
<br />
            cell.ReadOnly = false;<br />
<br />
            if (aufwandDataGridView.IsCurrentCellDirty)<br />
            {<br />
<br />
                aufwandDataGridView.CommitEdit<br />
                    (DataGridViewDataErrorContexts.Commit);<br />
            }<br />
<br />
            //e.FormattedValue contains the item thart i selected in the ComboBox<br />
            cell.Value = e.FormattedValue;<br />
            //cell.Value is not changing it is still null. no exception is thrown.<br />
        }<br />

Can anyone please help me?

Kind regards and thx in advance
Me

Ok it's because of the VirtualMode property that i can't set the cell.value so easily.
But how can i set the cell.value if the cell is not databound?
