Shouldn't this be in the WPF or Silverlight forum?

As a quick aside, on line 45 of the C# code, why do you need to convert mylist[u] to string when it is already a string?

yes, i forgot to change it, the reason i convert it to string is because i use Integer and other form, so forget that, my problem is when i fill the first column the autocompletebox is ok but when tried to fill the second the first column become empty. what do you think the reason why is it happen?

[Skydiver]

Off the top of my head, I'm seeing a binding for the ItemsSource, but I'm not seeing a binding to where the actual value the user types in gets stored.

[Bertdecode]

ok i got your point, i tried to work with that ,and then i inform you after. thanks

[Bertdecode]

unfortunately i can't make it work, the problem is still occur.
Any help is appreciated... Thanks

[Skydiver]

Can you post your new code with the binding?

[Bertdecode]

I modify the itemsource of datagrid by adding MaterialCode where the First column of datagrid stored the data.

 public class SRItems
        {
            public string MaterialCode { get; set; }
            public string Description { get; set; }
            public string  Quantity { get; set; }
            
        }

and then also adding binding to autocompletebox

 <DataGridTemplateColumn FocusManager.FocusedElement="{Binding ElementName= autoCompleteBox1}" Header="Material Code" Width="180" x:Name="autoCompleteBox2">

                    <DataGridTemplateColumn.CellTemplate >
                        <DataTemplate >
                            <TextBlock  Text="{Binding MaterialCode}" />                                
                        </DataTemplate>
                        
                    </DataGridTemplateColumn.CellTemplate>
                    <DataGridTemplateColumn.CellEditingTemplate>

                        <DataTemplate>
                            <my:AutoCompleteBox HorizontalAlignment="Left" SelectedItem ="{Binding MaterialCode}" Margin="0,0,0,0" ItemsSource ="{Binding AllRoles, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}" x:Name="autoCompleteBox1" VerticalAlignment="Top" Width="180"/>
                        </DataTemplate>

                    </DataGridTemplateColumn.CellEditingTemplate>

                </DataGridTemplateColumn>

Thanks.

That is strange. I don't know what to tell you.

If instead of AutoCompleteBox, you used a plain old TextBox, does it work? If it does, have you tried moving up to a ComboBox? And if the ComboBox still works, then switching back to the AutoCompleteBox in theory should also work, but as you've observed it doesn't. It maybe time to download the source for the AutoCompleteBox and set breakpoints within it.
