Empty GridView in first loading

[milelena]

Hello

In my web page I have a Calendar which is associated with a DayRender procedure. In this procedure, I keep the visible month of the calendar to a Session("month").

In the same page, I also have a GridView presenting some results based on the Session("month") I have mensioned previously.

When I first load the page, the GridView presents no results, although it should do that. If I then refresh the page, the results are presented.

I was thinking that the DayRender procedure acts after the page loads, so the Session("month") value which is passed to GridView is null.

Do you have any idea how to solve this issue?

Thank you in advance
Elena
