Hi,

I get the following error when compling. Please help. Thanks.

Error:
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'ASP.management_genres_aspx' does not contain a definition for 'GridView1_SelectedIndexChanged' and no extension method 'GridView1_SelectedIndexChanged' accepting a first argument of type 'ASP.management_genres_aspx' could be found (are you missing a using directive or an assembly reference?)

And is the error message correct? Do you see the missing method define in the file's Code Behind? If not, remove the following:

onselectedindexchanged="GridView1_SelectedIndexCha nged"

You may have accidentally set up this handler, then undid your changes in Code Behind (or closed the file without saving it), accidentally leaving this in the markup.

Cheers.
