Question

i generated a page with an ASP Button which loads another page.

<asp:Button ID="ServerCredentials" runat="server" Text="Server Credentials" Font-Names="Verdana" Font-Size="12px" OnClick="Credential_Click" Width="135px"/>

Function which loads another page:

 Protected Sub Credential_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Response.Redirect("~/WebPage/Booking/ExchangeServer.aspx")
    End Sub

This code only works when i registered on the page with exchange data.

when i am not registered, nothing happens.

But if i put a onclientclick with any function, it works again.
like this:

<asp:Button ID="ServerCredentials" runat="server" Text="Server Credentials" Font-Names="Verdana" Font-Size="12px" OnClientClick="return CheckDateVonBis()"  OnClick="Credential_Click" Width="135px"/>

what is the difference between onclick and onclientclick?

how can i solve this problem?

Answer 1

onclick for server side function and onclientclick for client side

OnClientClick : if you wish call javascript function

OnClick : if you wish call code behind function declared in server side
