hi,
If there is any validation in
Transferring_Information1.aspx
page
then put CauseValidation
<asp:Button runat="server" ID="cmdPost" CauseValidation="false" PostBackUrl="~/Topics/Transferring Information/Transferring_Information2.aspx"
Text="Cross-Page Postback" />
Another reason might be Redirection URL, remove the extra space and rename the directory accordingly and try again, i.e. rename Transferring Information to TransferringInformation and use this code below,
<asp:Button runat="server" ID="cmdPost" CauseValidation="false"
PostBackUrl="~/Topics/TransferringInformation/Transferring_Information2.aspx"
Text="Cross-Page Postback" />
Hope this will help.
