var flag = true;
var dropdowns = new Array(); //Create array to hold all the dropdown lists.
var gridview = document.getElementById('<%=gv_accounting.ClientID%>'); //GridView1 is the id of ur gridview.
dropdowns = gridview.getElementsByTagName('select'); //Get all dropdown lists contained in GridView1.
for (var i = 0; i < dropdowns.length; i++) {
if (dropdowns.item(i).value == '0') //If dropdown has no selected value
{
flag = false;
break; //break the loop as there is no need to check further.
}
}
if (!flag) {

Hi Ankit,

On Gridview rowdatabound event add an attribute onchange as : 

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType == DataControlRowType.DataRow)
DropDownList ddl = new DropDownList();
ddl=(DropDownList) e.Row.FindControl("ddlID");
ddl.Attributes.Add("onblur", "onchangemethodValidate(this);");
}
}

 And Aspx page: 

<script>
function onchangemethodValidate(ddl){
alert($("#ddl").val());
}
</script>
