I have a dropdownlist and I want to add tooltip for dropdownlist items. I tried with following code, but it does not work;
for (int d = 0; d < drpID.Items.Count; d++)
{
drpID.Items[d].Attributes.Add("title", drpID.Items[d].Value);
}
Can anyone help me on this?
Try like this;
public void Tooltip(ListControl lc)
{
for (int d = 0; d < lc.Items.Count; d++)
{
lc.Items[d].Attributes.Add("title", lc.Items[d].Text);
}
}
You should use .Text property for tooltip, not for .Value.
Check out for this link: http://www.dotnetspider.com/resources/5099-Tool-tip-for-DropDownList-ASP-NET.aspx
Try following code:
foreach (ListItem item in drpID.Items)
{
item.Attributes.Add("Title", item.Text);
}
You should try this
protected void ddlDetails_DataBound(object sender, EventArgs e)
{
DropDownList ddl = sender as DropDownList;
if(ddl!=null)
{
foreach (ListItem li in ddl.Items)
{
li.Attributes["title"] = li.Text;
}
}
}
I know this thread was regarding a databound control, but in the infrequent case where you have actually hard coded the ListItem values in the aspx page, I simply added a
<asp:ListItem Id="liNumberOne" Runat="server" title="My nifty help text" />
attribute to the ListItem tag itself and it worked just fine. Sure, I got a complaint about that not being a valid attribute but when the page rendered, it came along and then it WAS a valid attribute.
I've just had to implement a tooltip on a programatically populated DropDownList. I found that the title attribute was being set to the Text property automatically and I couldn't override it, even at PreRender.
None of the suggestions on this thread worked, and I was eventually forced to use a jQuery approach.
When creating the list item I set a custom attribute with the tooltip text
ListItem item = new ListItem("Name", "Value");
item.Attributes.Add("tooltip", tooltip);
ddl.Items.Add(item);
Then fire the method below with a start up script
function SetTooltip() {
jQuery('#<%=ddl.ClientID %> option').each(
function () {
jQuery(this).attr('title', jQuery(this).attr('tooltip'));
}
);
}
Pretty it ain't. But it works.
foreach (ToolStripItem item in yourToolStripName.DropDownItems)
{
item.ToolTipText = "tool strip item message";
}
