OnSelectedIndexChanging being called twice

[Marc Scheuner]

Folks,

I have a rather basic GridView on my ASP.NET page, and when a particular row
is selected (by clicking on an image in a TemplateField column), I expect
the page to be created and then go into my OnSelectedIndexChanging event
handler. In there, I evaluate the info I get and I have a
Response.Redirect(......) to my details page.

Trouble is: once I run through that event handler, instead of going to
details page, the whole process is repeated....my page with the GridView is
created, the Page_Init and Page_Load methods executed, and I fall into the
OnSelectedIndexChanging event handler once again. Now the second time
around, my Response.Redirect seems to work - but it just seems weird that
the overview page gets re-created and the handler executed twice, before the
Redirect actually works....

Any ideas??

Thanks!
Marc
