Hi,

I want to dynamic caml query based on query string.Let me explain it with example

my query sting can be anything

?cat=ABC&cat=ABD&cat=ABE...
?Cat=ABC
?Cat=ABC&cat=ABL

so no. can be anything now the problem begins

I want to query my sharepoint list based on this query string

if (HttpContext.Current.Request.QueryString["cat"] != null)
        {
            string _cat = HttpContext.Current.Request.QueryString["cat"].ToString();
        }

so this way my string contains all the query

string _cat=ABC,AD,....all.

I want to query my sharepoint list based on these query string and with "AND"

where title=ABC and title=AD ....

if there is only one query string then only where title=ABC....so I want my query string should be dynamic.... Any idea how to acheive this??
