Issue Defining ToolTips on ASP.NET DropDownList items

I am trying to use the “title” attribute for ASP.NET DropDownList items to display mouseover tooltips for each item. However, it seems like after I make a choice, and reopen the list, only tooltips for the selected item and below show the tooltips. For example, if I have 10 items in my list, and choose the 7th one, only 7-10 show tooltips if I re-open the list.

I have done a View Source of the page in the browser, and all the “title” attributes are present, but the upper ones don’t display on mouseover.

If I select the top item in the list, then they all display again. But if I choose the bottom item in the list, only that item has a tooltip that comes up.

I have tried both defining a derived class from DropDownList and overriding the SaveViewState and LoadViewState, as well as re-adding the attribute on a postback; both show the same behavior.

You may use the below to make the selected item go to top of the list and all other items will appear below.

protected void Page_PreRender(object sender, EventArgs e) { var itemIndex = DropDownList1.SelectedIndex; if (itemIndex != -1) { var item = DropDownList1.Items[itemIndex]; DropDownList1.Items.RemoveAt(itemIndex); DropDownList1.Items.Insert(0, new ListItem(item.Text, item.Value)); } }
