hii,
how can i make automatic pop up alert message when i open a particular page?
the alert message is used to identify the products that reached its stock limit by comparing both columns in sql server.
it is like when the user update the amount of product in product page and the amount is equal or less than the stock limit then after the user refresh the page then the alert message will be come out automatically. for example, the stock limit is 100, then user update product amount to 90 then after refreshing the page the alert message will come out.

please give me solution for this problem. thank you

you can write your checking code in your page load event and according to your condition, you can show alert messages to user, so this code every time execute when you reload your page.

Try this:

JavaScript

<script language="javascript" type="text/javascript">
function IsValidStockValue()
{
var uid;
var temp=document.getElementById("<%=txtValue.ClientID %>");
uid=temp.value;
if(uid > "Stock limit value")
{
alert ("Please Enter Actual Stock Value.");
return false;
}
else
{
return true;
}
}
</script>

{
SqlConnection connection = new SqlConnection("Data Source=MELINA_YEO-VAIO;Initial Catalog=InventorySystem;Integrated Security=True");

SqlCommand abc = new SqlCommand("Select case when (P_Amount <= SafetyStockamount) then 'Limit stock has been reached' end as Alert from Product");
