Hello everyone,
Something weird is happening in my website (asp.net 2.0 website) running it using internet explorer 7.0.
I am putting tool tip on everyday item of a drop down list using this line of code:

For Each itm As ListItem In ddlAccountNumber.Items
itm.Attributes("title") = itm.Text
Next

 The tool tip is displayed sometimes and not displayed in other times, randomnly.
Can you help?

Hi Goodway,

Your tip is displayed somtimes and not displayed in other times.

Based on my experience, you may put the code into wrong place.

You can try the following method.

    protected void DropDownList1_PreRender(object sender, EventArgs e)
    {
        foreach (ListItem itm in DropDownList2.Items)
        {
            itm.Attributes["title"] = itm.Text;

        }

    }

Let me know if I have misunderstood what you mean.
Thanks.
Hope it helps,
Hua Jun

Try This 

for(int i=0; i<=ddlAccountNumber.items.count-1; i++)
{
       ddlAccountNumber.Item[i].Attributes.Add("Title", ddlAccountNumber.Item[i].Text)
}
