  How to Assign Value to ListBox.Items.Insert

  Jul 01, 2008 07:58 AM|LINK

   I have e.g 3 items in my ListBox

   
  ITEM 1
  ITEM 2
  ITEM 3

   
  Lets assume ITEM 2 and ITEM 3 is get from data source and I set its DataTextField as "Name" and DataValueField As "ID"

   
  ITEM1 is insert by the following command  ListBox1.Items.Insert(0,"ITEM 1")

  How do I assign e.g a value "item1value" to ITEM 1 and not changing its text.
  
  Means it show
  ITEM 1
  ITEM 2
  ITEM 3

   
  But when I call ListBox1.SelectedValue (assume at this moment i select ITEM 1) , it will return me item1value instead of ITEM 1

   

  Thanks,
  Baoky

  You have to create a new ListItem and use it instead of just inserting a string 

  lstTest.Items.Insert(0, new ListItem("ITEM 1", "0"));

  try this...

  ListItem li = new ListItem();
  li.Text = "Item 1";
  li.Value = "Item 1 Value";

  ddlist.Items.Insert(0, li);

  if  you using dataset means why you are inserting values into Listbox . just u can bind data into datalist using following method

  ListBox1 .DataSource = Datasetname.Tables[tablename ];

  ListBox1.DataValueField = "ID";ListBox1.DataTextField = "items";

  ListBox1.DataBind();

   

  when you selelcting listbox why you are getting item1 only behalf of  Id means .. you have not set the value for listitem.

  so u can use following code for inserting value

   

  Dim NewItem As ListItem
  NewItem = New ListItem("text","value")
  ListBox.Items.Add(NewItem)
  
  or
  
  ListBox.Items.Add(New ListItem("text","value"))
  
  ListBox.Items.Insert(index, New ListItem("text","value"))
  ListBox.Items.RemoveAt(index)
  ListBox.Items.Clear()
