Solution 1

It very simple with the help of Jquery

value="change" />

here i have two button named read or changed and a textbox.
read button is simply reading the attribute value and the change button is changing the value of attribute.

here is the Jquery code

$(function () {

$("#Button5").click(function () {
alert($("#Text1").attr("name"));
});

$("#Button6").click(function () {
$("#Text1").attr("name", "Singh");
});
})

"</select>";

try by changing the name of the dropdown list..

DropDownList div2 = (DropDownList)Master.FindControl("ctl00_ContentPlaceHolder1_perage['"+pcnt+"']");

i think this will work fine..

if your are creating dropdown from code behind then you wiil not able to find that.beacuse on every postback you have to create the dropdown list.
