This suggests you to have a dropdown where user can select country and thus currency.
Based on the dropdown selection, get the latest data, convert anything that needs to be based on currency multiplier and then use the modified data as input for the page display.
Try out.

Hi,
Actually,I'm not using a dropdown list.The website is an international one in which there are different home pages for different countries.So,I want to show the images and prices of different watches on the website and the price should be updated dynamically depending on the exchange rate.So,how do I get the exchange rate values to do such a dynamic update?

Even then, there must be something that is driving the localization. Dropdown is just a way to know what country/currency. Whichever way you are chaning your homepage, based on the same paramter your data should be changed/driven.

I think you are looking to get the most recent exchange rate.
Check out: http://www.webservicex.net/ws/WSDetails.aspx?CATID=2&WSID=10[^]
You could write a small program that would invoke this webservice for the currencies you desire and store those rates in a lookup table which your drop-down list would be bound.
Good luck.

Not advisable as you will be blocking sever memory and can be very bad when multiple people connect.

Session timeout is set in Web.Config file. Default is 20 min. Change it to as per need there and will be used by IIS. You can also have FormsAuthentication timeout if you are using FormsAuthentication.
Following is sample change in Web.Config file:
<system.web>
<authentication mode="Forms">
<forms timeout="55"/>
</authentication>
<sessionState timeout="60" />
</system.web>

I have a variable that is declared in a user control. It is the value of a drop down list in the user control. When I try to use it in an If statement on an aspx page it says that the variable is not declared. Is there a way to declare the variable on the aspx page or make it recognize that it is declared on the user control page?
I'm calling the code at the top of the aspx page
<%@ Register src="pType.ascx" tagname="pType" tagprefix="uc2" %>
I'm using the if statement
<%If pt.SelectedValue = "1" Then%>
\\do things
<%End If%>
In the control pt is defined by
<asp:dropdownlist id="pt" runat="server">
Thank you!

Hi,
have you tried like this.
say you have used the user control like below in aspx page.
<uc2:pType ID="pType1" runat="server" />
so, in your code behind of the aspx page,
dim pt as DropDownList = CType(pType1.FindControl("pt"), DropDownList)
If Not pt IsNothing Then
If pt.SelectedValue = "1" Then
End If
End If
hope it helps

What do you want to do? You can always tie up the dropdown onchange (client side) or selectedchange (server) events to check the value and do some work.

System.Data.DataTable dt = (System.Data.DataTable)System.Web.HttpContext.Current.Cache["SesionList"];

Member 8701813 wrote: document.getElementById("<%=ddlusertypeid.ClientID %>").value != "")
Since you said, 'select' is displayed by default, change the above code to:
document.getElementById("<%=ddlusertypeid.ClientID %>").value != "select"
Since dropdown can have values 'select' or 6,7,8,9,10, any value other then select is ok.

i did it...its not working....any other solution pls...

It's not about any other solution. It's about implementing it correctly.
Debug and see which condition is executing it. Based on what you shared, I am sure it was 'select' instead of empty. (Make sure correct case is used) (Select OR select OR SELECT)
|
|
|
|
|
ddlusertypeid.Items.Insert(0, new ListItem("Select", "0"));
pls have a look at this statement...here i am using "Select" and not "SELECT".
|
|
|
|
|
Try this:
document.getElementById("<%=ddlusertypeid.ClientID %>").selectedIndex != 0
var e = document.getElementById("<%=ddlusertypeid.ClientID %>");
document.getElementById("<%=ddlusertypeid.ClientID %>").options[e.selectedIndex].text != "Select";
Do Javascript debugging if you face issues.

hi thanks
document.getElementById("<%=ddlusertypeid.ClientID %>").selectedIndex != 0
