    I tried loading the SessionDataSource.cs to my app_code folder but still receive the error:

    Generation of designer file failed: Unknown server tag sds:SessionDataSource.  I'm able to compile fine.  However this doesn't work.

    Please help.

    Hi Atanas,

    I´m trying to use this sample:

    But, only changing "sds:SessionDataSource" by "asp:SqlDataSource" doesnt works.

    Please, how can I do this?

    Thanks, Daniel

    Hello Daniel,

    Simply replace the SessionDataSource with asp:SqlDataSource and remove the DisplayWarning="false"   and PrimaryKeyFields="ID" properties, in order to get the demo locally runnable.

    Hope this would help.
