using the code

before getting into working nature of code let me explain u about the trick i used in this , getting clientid of particular cells textbox in rowediting event and registrering along with javascript gives exact needs to set datetime picker in gridview

            protected void gridview1_rowediting(object sender, gridviewediteventargs e)
    {
        int f;
        f = e.neweditindex; 
        f += 2;
       
        string clientid = "ctl00_contentplaceholder1_gridview1_ctl";

        string startdate;
        if (f <= 9)
        {
            startdate = clientid + "0" + f.tostring() + "_txt_when";
        }
        else
        {
            startdate = clientid +  f.tostring() + "_txt_when";
        }
        

        string targetdate;
        if (f <= 9)
        {
            targetdate = clientid + "0" + f.tostring() + "_txt_tdate";
        }
        else
        {
            targetdate = clientid +  f.tostring() + "_txt_tdate";
        }
        

        string script;
        script = "<script language=" + (char)34 + "javascript" + (char)34 + "  >";
        script += "function getdate(result,ctrl)";
        script += "{";
        script += "if(ctrl == 'txt_when' )";
        script += "{";
        script += "document.getelementbyid(" + (char)34 + startdate + (char)34 + ").value      = result;";
        script += "document.getelementbyid(" + (char)34 + startdate + (char)34 + ").innertext  = result;";
        script += "document.getelementbyid(" + (char)34 + startdate + (char)34 + ").readonly   = true;";
        script += "}";
        script += "else";
        script += "{";
        script += "document.getelementbyid(" + (char)34 + targetdate + (char)34 + ").value      = result;";
        script += "document.getelementbyid(" + (char)34 + targetdate + (char)34 + ").innertext  = result;";
        script += "document.getelementbyid(" + (char)34 + targetdate + (char)34 + ").readonly   = true;";
        script += "}";
        script += "}";
        script += "</script>";
        l1.text = script;
    }
