Hello,
i have a problem with my gridview, i have a string that shows me a result from a search box in another page, and i want to add sql "like" command to my string:
strSql = "select * from tbl_search where tx_search='" + Request.QueryString["selectedvalue"].ToString() + "'";
For sure i need a command parameter too, but i don't know how to write it and how to put sql "like" in this string.
Thank you!
