In my webform project, I have implemented a dropdown menu with custom tooltips for the list items. These tooltips are different from the display field and value field, which can be considered as the third column. To bind the tooltips to the list items using the DataTable, I have included the following code:
private void AddToolTipToDDL(DataTable dt, DropDownList ddl)
{
foreach (ListItem item in ddl.Items)
{
if (item.Value != "0")
{
DataView dv = new DataView(dt);
dv.RowFilter = "MasterID = " + item.Value;
string s = Convert.ToString(dv[0].Row.ItemArray[4]);
item.Attributes.Add("Title", s);
}
}
}
This code snippet will add a title attribute to each ListItem. Now, my goal is to style the tooltip that appears when hovering over the title attribute. How can I accomplish this task?
