Hello,

First, I already found this same topic under Forums -> WinForms -> GridView, but that thread does not answer to my problem.

I have radGridView1 binded to DataTable. I can add new rows to grid and delete rows from grid.
Error "This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row." occurs when I remove latest row I have added.

Here is the code which removes selected row:

    
            private void button2_Click(object sender, RoutedEventArgs e)  
        
                    {  
        
                        List<DataRow> itemsToRemove = new List<DataRow>();  
        
                        foreach (DataRow item in this.radGridView1.SelectedItems)  
        
                        {  
        
                            itemsToRemove.Add(item);  
        
                        }  
        
                        foreach (DataRow item in itemsToRemove)  
        
                        {  
        
                            ((DataTable)this.radGridView1.ItemsSource).Rows.Remove(item);  
        
                            ((DataTable)this.radGridView1.ItemsSource).AcceptChanges();  
        
                        }  
        
                        DataTable emptyTable = new DataTable(); // this is for refreshing grid view  
        
                        radGridView1.ItemsSource = emptyTable;  // this is for refreshing grid view  
        
                        radGridView1.ItemsSource = myDataTable;  
        
                    }

Can you help me from here?

BR,
Tatu
