Refreshing a DataGridView in one form from another

Ari

Hey I have a form which contains a DataGridView which items are bound via a List. From there, I can edit a selected rows items by clicking a button which opens a new form which contains textboxes, combo boxes etc. Once I've finished editing the data, I close the edit form using a button, which takes me back to the main form. Now, once I exit the edit form, the DataGridView is suppose to have its items refreshed so that the updated items are displayed. At the moment, the editing is working fine, however the datagridview is not refreshing. However, if i simply rebind the list in the main form it works, it should work from the edit form but it simply isn't.

Here is a snippet of code from the edit form exit button which is suppose to be doing the refreshing:

MessageBox.Show("Client successfully edited");

Client.DisplayClients(Clients.clients, mForm.DataGridViewProp);

mForm.DataGridViewProp.EndEdit();

mForm.DataGridViewProp.Refresh();

mForm.DataPanel.Refresh();

this.Close();

mForm is an instance of the main form:

private mainForm mForm = new mainForm();

Clients.clients is a List within a class, and DisplayClients is a method within the client class:

public static void DisplayClients(List cList, DataGridView dgv)

{

dgv.Rows.Clear();

foreach (Client c in cList)

{

dgv.Rows.Add(c.id_, c.firstName_, c.lastName_, c.homeAddress_, c.workAddress_,

c.emailAddress_, c.homePhoneNumber_, c.cellPhoneNumber_);

}

}

Any help on the matter is greatly appreciated.
Thanks,
Ari

Can you provide the additional clarification I requested? Is it possible to use the same List to update the data?

Also note that you will get more flexibility if you use the Data Sources window to create a table and use that as the data source instead of the list. You can create a table that only exists in memory but otherwise has all the features that a DataTable has whose data comes from a SQL Server.

Well, the DataGridView displays a list of clients - List

And is done so using the datasource property.

What does "bound via a List" mean? I am not sure of that. Is it bound using a Table Adapter or an Entity? If so, then I am not sure what "list" means.

Assuming that the DataGridView is bound using a TableAdapter, then is it possible to edit the data using the same TableAdapter that is used for the DataGridView? If that is possible, then that is the ideal solution. Otherwise there are other possibilities of course but first consider this first possibility.
