JavaScript

function callonclick(obj)
{

var sdt = obj.split("_");
var chkDeny=document.getElementById('ctl00_ContentPlaceHolder1_gv_'+sdt[3]+'_chkDeny');
var txtReason=document.getElementById('ctl00_ContentPlaceHolder1_gv_'+sdt[3]+'_txtReason');
if(chkDeny.checked)
{
txtReason.value="";
txtReason.disabled =false;
}
else
{
txtReason.value="Enter Reason";
txtReason.disabled =true;

}
}


On Aspx page

<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</EditItemTemplate>
<ItemStyle HorizontalAlign="Center" />
<ItemTemplate>
