Question

I have an asp:DropDownList on a page that, due to the 1024×768 development standard can truncate some of the text values in the dropdown (not enough of them, apparently, to redesign the layout ), so I need to display a tooltip of the selected value when a dropdown item is being selected (i.e. when the dropdown is shown and an item is being hovered over), preferably only when the text for that item is being truncated.

Is this possible by default, javascript hacking or only my imagination?

Answer 1

foreach (ListItem _listItem in this.DropDownList1.Items)    
{     
  _listItem.Attributes.Add("title", _listItem.Text); 

}

// add a tooltip for the selected item also

DropDownList1.Attributes.Add("onmouseover", this.title=this.options[this.selectedIndex].title");
