Hi,
I would like to know:
a) How to insert a new row in the RadGridView by clicking on a button rather than pressing the insert key.

b) How can i also insert multiple rows using the button? Currently when pressing the insert key twice does not insert 2 new rows.

Regards,
Mark.

Hello MarkBr,

The Insert key is intended to toggle between visible and hidden state of the new row. So pressing it multiple times will just toggle visibility multiple times.

The workaround is to add multiple empty records to the ItemsSource of the grid on pressing a button. Later the user may focus and edit the empty cells.
I am preparing a sample project for you to demonstrate how this may be done. I'll send it to you later today.

Hi Pavel

I would also be interested in this project to see how this is done. Is it also possible to have a copy of the sample project ?

Thanks

Gavin

Hi Gavin Bryan,

I am attaching Pavel's project. It binds to an ObservableCollection of Customer objects and upon clicking the Add Customers button inserts five empty objects. RadGridView picks those up and displays them in empty rows:

private void Add5Rows() 
    ObservableCollection<Customer> data = (ObservableCollection<Customer>) this.RadGridView1.ItemsSource; 
    for (int i = 0; i < 4; i++) 
    { 
        Customer blankCustomer = new Customer() { CustomerID = -1 }; 
        data.Add(blankCustomer); 
        pendingCustomers.Add(blankCustomer); 
    } 
 
private void AddCustomers_Click(object sender, RoutedEventArgs e) 
    Add5Rows(); 
 

The code also keeps track of newly-inserted customers by storing them in the pendingCustomers collection. Those customers are sent to the server whenever the user clicks the Save button:

private void SaveNewCustomers_Click(object sender, RoutedEventArgs e) 
    SavePendingCustomers(); 
 
 
private void SavePendingCustomers() 
    foreach (var Customer in this.pendingCustomers) 
    { 
        client.AddCustomerAsync(Customer); 
    } 
 
    this.pendingCustomers.Clear(); 
 


Sincerely yours,
