set visibility of label in datagrid IF text string present

[footballhead]

Hello-

I have page on my site that displays the results of a product search in
a datagrid.

There is a text field that has a full description of the product named
FullInfo. I have placed some keywords in this description that denote
certain things about the product such as SALE, CLOSEOUT, FREE_SHIPPING,
etc.

I have labels in the datagrid template for each condition above (SALE,
CLOSEOUT, etc). These lables are all set to Visible="False". I'd like
to make these visible IF the keyword appears in the FullInfo text
field.

I am stuck on figuring out how to read through the text in the FullInfo
field for the keywords. I have tried using a sub-routine with an IF
statement and IndexOf to determine if the keyword is present but that
did not work.

Any help is appreciated, thanks!

Are you able to extract the string from the cell?


Look into Regular Expressions (Regex)

IndexOf would certainly work.

dim i as integer

Dim strTest As String = "we have a SALE on foxes"

i = strTest.IndexOf("SALE")

if i > 0 then....

Jeff-

I've got that exact code working on other pages where the field in
question has been placed into a Label.

On this page that I am working on, the text that I need to search
through is in the datagrid. It's being called like this:
<%# DataBinder.Eval(Container.DataItem, "FullInfo") %>

I succesfully added a new Label named lblFullInfo INSIDE that datagrid
template and set the Text property to = <%#
DataBinder.Eval(Container.DataItem, "FullInfo") %>. This works and
shows up when I test the page.

However, when I add my script, I get the error:
Name 'lblFullInfo' is not declared.

Here is my script:

<script runat="server">
dim isFreebie as String = lblFullInfo.text
if isFreebie.IndexOf( "freebie" ) > 0 Then
lblFullInfo.visible = True
End if
</script>

NOTE: I only have access to the aspx page, I cannot get to the
code-behind.

Thanks!
