when i wish to set a value in a field of a new collection item, as below, how do i get the collection to accept the value like it would if I had  typed the value in a cell of the bound datagrid. The exapmle below will always correctly set the value of the field in the datagrid when I click a new line. and it add an item. But the row is not added complely until I add some value and validate the row in the grid. What do I need to do to have the addnew add a complete row that coul dbe saved without a manual cell validate event in the grid.

Code:

namespace BusinessObjects
{
	public partial class Component : esComponent
	{
      
      
      public override void AddNew()
      {
         base.AddNew();
         int next_id = this.Collection.Count;
         this.SetColumn(BusinessObjects.ComponentMetadata.ColumnNames.AssemblyName,"Line " + next_id.ToString());

        
         
        
      }  
	}

Code:

base.AddNew();

Code:

this.AssemblyName = "Line " + next_id.ToString());
