Get Grid View Hidden Field Value Using JavaScript/Jquery

Forgive my English, I had one challenge in my project I,e whenever I started to access hidden field value which in grid view using JavaScript or Jquery, I'm getting compilation err

Solution 1:

I'm not sure the code

document.getElementById("<%=PatientRefferalId.ClientID%>")

will work, because you don't have only one "PatientRefferalId", but you get many (as many as numbers of rows in your gridview).

I don't know if there is a cleaner way, but I can do what you want by using this javascript code

var gv = document.getElementById("<%=gvPatient.ClientID%>");
var Rows = gv.getElementsByTagName("tr"); // Get all the rows from your gridview (rendered as html table).
// you can loop through the rows or if you know the row index, you can do:
alert(Rows[2].childNodes[0].children[0].value); // Show you the first control (the hiddenfield) of the first cell of the row #2.

Hi This post may help you.

var c = document.getElementsByTagName("table");
    for (var i = 0; i < c.length; i++) {
        if (c[i].id.indexOf("GridView1") > -1) {
            var hidd = c[i].getElementsByTagName("input");
            for (var j = 0; j < hidd.length; j++) {
                if (hidd[j].type == "hidden")
                    alert(hidd[j].id);
            }
        }
    }

    <asp:Content ID="Content2" ContentPlaceHolderID="cphContent" runat="Server">
        <script type="text/javascript">
            function DispValue(btnShow) {
  var parentRow = $(btnShow).closest("tr");
var hiddenField=parentRow.find('input[id$=PatientRefferalId]');
 alert(hiddenField.val());

    return false;
            }
        </script>

        <div align="left" style="float: left; margin-left: 5px;">
