Hello friends,

I have one update button in application when i click update button then it opens a panel of checkboxes. With selection of checkboxes i am updating my database with my datagrid's value. It is successful if i am selecting the checkboxes. But when i left checkboxes and again i click on my update button then my application crashed on firefox. I want to know what is d reason behind this.Below is my code what i am using:
private void btnUpdate_Click(object sender, RoutedEventArgs e)
{
if (myDataGrid.ItemsSource != null)
{
grdProduct.Visibility = Visibility.Visible;
grdAttrbutes.Visibility = Visibility.Visible;
btnUpdate.Visibility = Visibility.Collapsed;
btnUpdateLst.Visibility = Visibility.Visible;
}
else
{
MessageBox.Show("Please open the file first which you want to update..");
}
}
void client_UpdateDatabaseCompleted(object sender, AsyncCompletedEventArgs e)
{
this.isWorking = false;
myProgressBar.Visibility = Visibility.Collapsed;
myDataGrid.Visibility = Visibility.Visible;
MessageBox.Show("Process Complete", "ExceltoSql", MessageBoxButton.OK);
foreach (UIElement elem in grdProduct.Children)
{
if (elem is CheckBox)
{
((CheckBox)elem).IsChecked = false;
}
}
foreach (UIElement elem in grdAttrbutes.Children)
{
if (elem is CheckBox)
{
((CheckBox)elem).IsChecked = false;
}
}
}
private void btnUpdateLst_Click(object sender, RoutedEventArgs e)
{
if (myDataGrid.ItemsSource != null)
{
ObservableCollection<ExcelClass> Lst = new ObservableCollection<ExcelClass>();
MessageBoxResult result = MessageBox.Show("Are you sure to update the data?", "Update Data", MessageBoxButton.OKCancel);
if (result == MessageBoxResult.OK)
{
ExcelClass update = new ExcelClass();
if (chkShippingCost.IsChecked == true)
{
update.ShippingCost = "1";
Lst.Add(update);
}
if (chkProductDescription.IsChecked == true)
{
update.Discription = "2";
Lst.Add(update);
}
if (chkProdName.IsChecked == true)
{
update.PName = "3";
Lst.Add(update);
}
if (chkColor.IsChecked == true)
{
update.COLOR = "4";
Lst.Add(update);
}
if (chkCategory.IsChecked == true)
{
update.CATEGORY = "5";
Lst.Add(update);
}

Lst.Add(update);
}
if (chkSP.IsChecked == true)
{
update.SP = "8";
Lst.Add(update);
}
if (chkCP.IsChecked == true)
{
update.CP = "9";
Lst.Add(update);
}
if (chkSPWithVat.IsChecked == true)

}
if (chkVat.IsChecked == true)
{
update.Vat = "11";
Lst.Add(update);
}
if (chkQty.IsChecked == true)
{
update.Qty = "12";
Lst.Add(update);
}
}
else if (result == MessageBoxResult.Cancel)
{
foreach (UIElement elem in grdProduct.Children)
{
if (elem is CheckBox)
{
((CheckBox)elem).IsChecked = false;
}
}
foreach (UIElement elem in grdAttrbutes.Children)
{

}
}
grdProduct.Visibility = Visibility.Collapsed;
grdAttrbutes.Visibility = Visibility.Collapsed;
btnUpdateLst.Visibility = Visibility.Collapsed;
btnUpdate.Visibility = Visibility.Visible;
//return;
}
if (Lst.Count != 0)
{
myDataGrid.Visibility = Visibility.Collapsed;
myProgressBar.Visibility = Visibility.Visible;
this.isWorking = true;
WcfServiceClient client = new WcfServiceClient();
client.UpdateDatabaseCompleted += new EventHandler<AsyncCompletedEventArgs>(client_UpdateDatabaseCompleted);
client.UpdateDatabaseAsync(Lst);
}
else if(Lst.Count == 0)
{
MessageBox.Show("Please click the checkboxes which you want to update..", "Updata Data", MessageBoxButton.OK);
return;
}
}
}
void client_UpdateDatabaseCompleted(object sender, AsyncCompletedEventArgs e)
{
this.isWorking = false;
myProgressBar.Visibility = Visibility.Collapsed;
myDataGrid.Visibility = Visibility.Visible;
MessageBox.Show("Process Complete", "ExceltoSql", MessageBoxButton.OK);
