Hi! I have a gridview wherein datas are displayed and the first column has a link. Now i want to select a data on that gridview by clicking that databound field, pass the value of that link and display data on the other page. How can i do this?

you can use a HyperLinkField like this:

   <asp:hyperlinkfield headertext="Title"
      datatextfield="title"
      datanavigateurlfields="title_id" 
      datanavigateurlformatstring="details_title.aspx?titleid={0}" />

here's an example: http://authors.aspalliance.com/aspxtreme/webforms/controls/addinghyperlinkfieldstogridview.aspx

so, now on details_title.aspx you could parse the querystring for the titleid and load appropriate data

public partial class Test: System.Web.UI.Page
{
        int TitleID = 0;
        protected void Page_Load(object sender, EventArgs e)
        {
            
            if (Request["titleid"] != null)
            {
                TitleID = Convert.ToInt32(Request["titleid"]);
                //get data with that TitleID etc 
            }
        }
}
