setting the font color to red for Dropdownlist control list item

Hi,

I am trying to change the font color for the items in a dropdownlist control
at run time using ASP.NET 2.0.

DropDownList1.Items[i].Attributes.Add("style", "color:red");

But when I run the application, I don't see any color change.

I am using Visual Studio 2005, ASP.NEt 2.0.

Any help would be great!On Mar 19, 4:06 pm, Rekha <R...@.discussions.microsoft.comwrote:

If you want the color for the entire list to be changed, then (in C#):
DropDownList1.ForeColor = Color.Red;

It's a known bug, it doesn't work.
Something as simple as :
<option style="color: red;">Something</option>
...works.

Also, you can use a Listbox instead of a DropdownList if you want to do it programmatically.
They have roughly the same functionality, anyway.

myconnection = New SqlConnection("Server=YourServer;Integrated Security=True;Database=Northwind")
myda = New SqlDataAdapter("Select * from Products ", myconnection)
ds = New DataSet()
myda.Fill(ds, "AllTables")
dim i as Integer
For i = 0 To ds.Tables(0).Rows.Count - 1
list1.Items.Add(New ListItem(ds.Tables(0).Rows(i)("UnitPrice"),
ds.Tables(0).Rows(i)("ProductID")))
If ds.Tables(0).Rows(i)("UnitPrice") <= 40 Then
list1.Items(i).Attributes.Add("style", "color:red")
Else
list1.Items(i).Attributes.Add("style", "color:green")
End If
Next

Use anything you'd like for your conditions...

Thanks to everyone for your reply.

I know that this is a bug but wasn't sure if Microsoft fixed the bug or not.

*WAS* a bug ! :-)

In the previous example, I used a <SELECT directly:

<select name="DDL1" id="DDL1" size="10">

...but ASP.NET renders a dropdownlist control as a select, so there's
no problem getting a dropdownlist to render its contents in different colors.

I modified the example so it uses an ASP.NET dropdownlist control:

http://asp.net.do/test/dropdowncolor3.aspx
DDL1.Items.Add(New ListItem(ds.Tables(0).Rows(i)("UnitPrice"), ds.Tables(0).Rows(i)("ProductID")))
If ds.Tables(0).Rows(i)("UnitPrice") <= 40 Then
DDL1.Items(i).Attributes.Add("style", "color:red")
Else
DDL1.Items(i).Attributes.Add("style", "color:green")
End If
Next

That, and changing the <SELECT to :
<asp:DropDownList id="DDL1" size="10" runat="server" />

...produces the exact same HTML as the previous example.

http://asp.net.do/test/dropdowncolor2.aspx
and
http://asp.net.do/test/dropdowncolor3.aspx
to verify that.

Juan,

Thanks for your reply.

The issue that I have is I am updating the list box items color based on the
selection made in a calendar field. When the user selects a date in the
calendar field, the list box items are color coded. I am updating the listbox
items in the Calendar_SelectionChanged event but I don't see the color
changing.

Any ideas!!

Thanks!

I have tried Attributes.Add as well as CSSStyle.Add both worked for me

<asp:Dropdownlist id="ddlLimit" tabIndex="6" runat="server">
<asp:ListItem Value="100" Selected="True">100</asp:ListItem>
<asp:ListItem Value="250" style="color: #00AAAA;">250</asp:ListItem>
<asp:ListItem Value="500">500</asp:ListItem>
</asp:dropdownlist>

On page load

ddlLimit.Items[0].Attributes.Add("style", "color: #0000FF; font-size: 12pt");
ddlLimit.Items[1].Attributes.Add("style", "color: #00FFFF; font-size: 12pt");
ddlLimit.Items[2].Attributes.CssStyle.Add("color", "red");
