I'm getting errors after introducing Accordion/Accordion Panes into my code.
Can I get some assistance with this? I'm new to ASP.NET so I am still learning how to use its features.
This is the error:
Could not find control 'ProjInfoGridView' in ControlParameter 'ProjectNum'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Could not find control 'ProjInfoGridView' in ControlParameter 'ProjectNum'.
This is my code:
