Refreshing main form

Hi All,

I have two forms, one holding a list of all contacts named "frmContactsListing". The contact is selected from grid.

The other is named "frmEditContact", manages the edit of a single selected contact from "frmContactsListing".

The code from "frmContactsListing" looks as shown below:-

private void barButtonEditContact_ItemClick(object sender, ItemClickEventArgs e)

{

try{

var selectedContact = gridViewContacts.GetFocusedRow() as Contact;

frmEditContact editContact = new frmEditContact(selectedContact, _contactService);

editContact.ShowDialog();

}

catch (Exception Errhandler){

MessageBox.Show(Errhandler.Message);

}

And the code from "frmEditContact" looks as shown below:-

public frmEditContact(IContactService contactService) {

InitializeComponent();

_photoService = UnityConfig.GetContainer().Resolve();

_contactService = contactService;

}

public frmEditContact(Contact contact, IContactService contactService)

: this(contactService) {

this._contact = contact;

SelectedPhotoId = _contact.ContactId;

contactNameTextEdit.Text = _contact.ContactName;

physicalAddressTextEdit.Text = _contact.PhysicalAddress;

postalAddressTextEdit.Text = _contact.PostalAddress;

telephoneTextEdit.Text = _contact.Telephone;

photoBindingSource.DataSource = _photoService.GetById(_contact.ContactId);

byte[] byteImg = ImageToByteArray(contactPhotoPictureBox.Image);

}

private void simpleButtonAccept_Click(object sender, EventArgs e) {

try {

_contact.ContactName = contactNameTextEdit.Text;

_contact.PhysicalAddress = physicalAddressTextEdit.Text;

_contact.PostalAddress = postalAddressTextEdit.Text;

_contact.Telephone = telephoneTextEdit.Text;

contactBindingSource.EndEdit();

_contactService.Update(_contact);

byte[] byteImg = ImageToByteArray(contactPhotoPictureBox.Image);

var photoSelection = _photoService.GetById(SelectedPhotoId);

photoSelection.PhotoData = byteImg;

photoBindingSource.EndEdit();

_photoService.update(photoSelection);

} catch(Exception Errhandler) {

MessageBox.Show(Errhandler.Message);

}

public byte[] ImageToByteArray(Image img) {

System.IO.MemoryStream ms = new System.IO.MemoryStream();

img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

return ms.ToArray();

}

The simpleButtonAccept_Click method accepts the edit.

Now, How do I refresh "frmContactsListing" once the edit form is closed to accomodate the edit changes,

taking into cosideration I have updated two binding sources, contactBindingSource and photoBindingSource. Entity framework.

Thanks.

Peter Dzuya.

Thank you so much Madhanmohan. Please show me how to apply those methods within "frmEditContact" form since I am still learning C#. Thank you.

Please try this
public class frmEditContact:Form {
frmContactsListing _contactlisting;
public frmEditContact(IContactService contactService) {
InitializeComponent();
_photoService = UnityConfig.GetContainer().Resolve();
_contactService = contactService;
}
public frmEditContact(frmContactsListing contactlisting) {
_contactlisting = contactlisting;
this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.frmEditContact_FormClosing);
}
private void frmEditContact_FormClosing(object sender, FormClosingEventArgs e) {
_contactlisting.PerformRefresh();
}
public frmEditContact(Contact contact, IContactService contactService)
: this(contactService) {
this._contact = contact;
SelectedPhotoId = _contact.ContactId;
contactNameTextEdit.Text = _contact.ContactName;
physicalAddressTextEdit.Text = _contact.PhysicalAddress;
postalAddressTextEdit.Text = _contact.PostalAddress;
telephoneTextEdit.Text = _contact.Telephone;
photoBindingSource.DataSource = _photoService.GetById(_contact.ContactId);
byte[] byteImg = ImageToByteArray(contactPhotoPictureBox.Image);
}
private void simpleButtonAccept_Click(object sender, EventArgs e) {
try {
_contact.ContactName = contactNameTextEdit.Text;
_contact.PhysicalAddress = physicalAddressTextEdit.Text;
_contact.PostalAddress = postalAddressTextEdit.Text;
_contact.Telephone = telephoneTextEdit.Text;
contactBindingSource.EndEdit();
_contactService.Update(_contact);
byte[] byteImg = ImageToByteArray(contactPhotoPictureBox.Image);
var photoSelection = _photoService.GetById(SelectedPhotoId);
photoSelection.PhotoData = byteImg;
photoBindingSource.EndEdit();
_photoService.update(photoSelection);
} catch(Exception Errhandler) {
MessageBox.Show(Errhandler.Message);
}
}
public byte[] ImageToByteArray(Image img) {
System.IO.MemoryStream ms = new System.IO.MemoryStream();
img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
return ms.ToArray();
}
}
