How to find/access the Control inside the LongListSelector of Windows Phone 8/7 App

In this blog you will learn how to find/access the Control inside the LongListSelector.

To find the Control Whether it may be a Checkbox,TextBox,Loader,ImageBrush whatever it may be By using the Following code you can find the control in LongListSelector and do respective actions like enabling,disabling,hiding etc.For Example this is my LongListSelector I need to find a control and Hide it

<phone:LongListSelector
 x:Name="AddrBook"
 JumpListStyle="{StaticResource AddrBookJumpListStyle}"
 Background="Transparent"
 GroupHeaderTemplate="{StaticResource AddrBookGroupHeaderTemplate}"
 ItemTemplate="{StaticResource AddrBookItemTemplate}"
 LayoutMode="List"
 IsGroupingEnabled="true"
HideEmptyGroups ="true"/>

This is my Data Template of LongListSelector.

<DataTemplate x:Key="AddrBookItemTemplate">
   <StackPanel VerticalAlignment="Top">
       <TextBlock FontWeight="Bold"  Text="{Binding FirstName}" />
       <TextBlock Text="{Binding LastName}" />
       <TextBlock Text="{Binding Address}" />
       <TextBlock Text="{Binding Phone}" />
   </StackPanel>
</DataTemplate>

So What can I Do is I can Simply use the following code to get what control I want from the longlistselector .

Use the Below Code Wherever you wish to get Control inside LLS

LongListSelector myControl= (AddrBook as LongListSelector);
SearchVisualTree(myControl); //Finding The TextBlock In LongListSelector(in My Case)

private void SearchVisualTree(DependencyObject targetElement)
{
    var count = VisualTreeHelper.GetChildrenCount(targetElement);
    if (count == 0)
        return;
    for (int i = 0; i < count; i++)
    {
        var child = VisualTreeHelper.GetChild(targetElement, i);
        if (child is TextBlock) //Setting Control to be Find                  {
            TextBlock targetItem = (TextBlock)child;


            if (targetItem.Visibility == System.Windows.Visibility.Visible)
            {
                targetItem.Visibility = System.Windows.Visibility.Collapsed;
                return; //Setting visual Property of TextBlock to Collapsed
            }
        }
        else
        {
            SearchVisualTree(child);
        }
    }
}

Now its Done!Cheers

Thank You !
