How do I edit all rows in an ASP.NET ListView control at the same time?

Question

I would like to know how to put all of my ListView rows into edit mode at once. I am not looking for the traditional behavior of editing each row one at a time. The answer

Probably the easiest way is to just use the ListView's ItemTemplate, so in essence, the ListView is always in "edit mode":

    
        
            
                <%# Eval("department_id") %>
            
            
                
            
        
    
    
        

            No departments found.
        
    
    
        
            

            

                

                    
Department ID
                    
Name
                
            
            

                
        
    

You can then read the changed values when the user clicks the button:

protected void cmdSave_Click ( object sender, EventArgs e )
{
    foreach ( ListViewItem item in lvwDepartments.Items )
    {
        if ( item.ItemType == ListViewItemType.DataItem )
        {
            TextBox txtDepartmentName = ( TextBox ) item.FindControl( "txtDepartmentName" );

            // Process changed data here...
        }
    }
}
