  Say that you fire the SelectedIndexChanged event handler;

  Just add this code to find say Label control within selected item:

  Dim MyTitle As Label = CType(ListView1.Items(ListView1.SelectedIndex).FindControl("MyLabelControl"), Label)
  
  
  Label MyTitle = (Label)ListView1.Items(ListView1.SelectedIndex).FindControl("MyLabelControl");

  You can get the selected Item using SelectedIndex

  protected void ListView1_SelectedIndexChanged(object sender, EventArgs e)
  {
      ListViewItem selectedItem = ListView1.Items[ListView1.SelectedIndex];
  }

  Add OnselectedIndexChanged="ListView1_SelectedIndexChanged" for the listview in the page markup.

  Kulrom, thx for your replay..

  Hmm... Looks little bit complicated to understand.. I just want to get selected id from listview.

  i usually use gridview. In gridview, i can get selected value with :

  string id = GridView_Main.SelectedValue.ToString();

  and add : 

  OnSelectedIndexChanged="GridView_Main_SelectedIndexChanged"

  but i dont know how to get that value in listview..

  thanks,

  sansan, thx for your replay..

  can't i change "ListViewItem" with data type like string or int??

  ex : 

  string id = ........ ;

  coz i will use that id to filter my table like this: 

  var notification = db.DMSDataContext.Notifikasis.Where(p => p.IdNotifikasi.Equals(id)).Single();

  thanks,

  Please specify the datakeynames of the listview to ID and you can retrieve the value as shown below

  protected void ListView1_SelectedIndexChanged(object sender, EventArgs e)
  {
      string id = ListView1.SelectedDataKey.Value.ToString();
  }

  Hello Sansan,

  If I have many Fileds (With an Image), I can apply that or not? Or if user click on Image, please tell me how to get value?
