Before you can use the GEET classes in your web pages you must reference the GEETMultisheet dll which was installed into the Global Assembly Casche of your computer.

To set this reference, perform next steps:

1. Inside Solution Explorer select the web.config file and double-click it. Web.config file will open.
2. Locate the compilation section and insert the reference to the GEETMultiSheet assembly by adding the next line to the Assemblies section of the compilation section. <compilation debug="true"> <assemblies> <!-- next line to reference the GEETMultiSheet dll inside the Global assembly cache --> <add assembly="GEETMultiSheet, Version=1.3.2.0, Culture=neutral, PublicKeyToken=67ad70e900207353"/> </assemblies> </compilation>
3. Save and close the web.config file.

We have verified that whenever tags are not properly closed, the rendering from GEET Classes cease to work. In this case we reccommend you to:

1. try setting the page attribute EnableEventValidation="false"
2. test the Export to Excel again. If it works, your web page may have some tags closure missing or misplaced.
3. after tags correction please set the page attribute EnableEventValidation back to "true"

We have verified that setting a SqldataSource web control inside the TD tags of a TABLE makes the rendering of the Export to Excel to stop working.
