How to Get the value of selected Item in listbox(items loaded from DB using WCF service) to a Text box ?

Question

First, I consumed data from a database to listbox1. However, if I select the item, it does not go into textbox1! Instead, it shows a null reference error.

private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (null != listBox1.SelectedItem)
    {        
        string text = (listBox1.SelectedItem as ListBoxItem).Content.ToString();
        textBox1.Text = text.ToString();
    } 
}

Hi  shanmu995 ,

You want to show the selected Item in  textbox , right ?

Please try this , hope it will be helpful :

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (null != listBox1.SelectedItem)
    {
       //  string text = (listBox1.SelectedItem as ListBoxItem).Content.ToString();
         string s = listBox1.SelectedItem.ToString();
         textBox1.Text = s;

Hi Lisa Zhu ,

       thank you for your reply

      your code is not working because listbox1 values are consumed from database using WCF service in silverlight window phone. It show only name of the service

Hi shanmu995,
I am sorry for not  reading your post title carefully enought  , I thought you did a winform application ，so the code I gave is based on WinForm  application .Sorry.
And this forum does not support WCF related question /discussiion .
So , if you need help with the WCF ,please refer to : http://social.msdn.microsoft.com/Forums/en-US/wcf/ 

Thanks for your support  understanding .

Regards ,
