使用已编码的ui testmethod获取Silverlight列表项

Question

I have a very simple silverligt page which contains this listbox

<ListBox ItemsSource="{Binding itemList}" x:Name="list">
    <ListBox.ItemTemplate>
        <DataTemplate x:Name="datatemplate" >
            <Grid Name="grid" AutomationProperties.AutomationId="grid" >
                <TextBlock Text="{Binding Txt}" AutomationProperties.AutomationId="{Binding Id}"></TextBlock>
            </Grid>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

I want my Coded UI test to select one of this list item and click on it, but i don't know how to search for itemlists. I tried everything but i cannot figure out how to get it.

here is my simple testmethod

public void ClickOnItem()
{

    SilverlightList list = new SilverlightList(this.UISilverlightApplicatiWindow.UISilverlightApplicatiDocument.UISilverlightControlHoPane.UIItemCustom.UIMainPageMainPage.UIListList);
    list.SearchProperties.Add(SilverlightList.PropertyNames.AutomationId, "list");

    SilverlightListItem item = new SilverlightListItem(list);

    item.SearchProperties.Add(SilverlightListItem.PropertyNames.AutomationId, "3");
    Mouse.Click(item);
}

(where "3" is the third element in the list, ofc)

what have i to search for? do i need additional xaml tags?

I`m not really sure if this is what you want but:

Once you have the Framework element you can access the items using the "Items" property itself. Example

var item = list.Items[index]

or using Linq

var item = list.Items.First(c => c.Id == 3);

Once you have the item you can select it with SelectedItem property as follow:

list.SelectedItem = item;

or depending on the case

list.SelectedValue = item;

To fire the click event you can simply call it giving null parameters as

list.OnMouseLeftButtonDown(null)

Which means you want to fire it with no parameters.
