Hello,

Have installed the demo version onto Win 2003 server with MOSS 2007.  All the demo gauges work fine.

I've installed / registered the web parts into a separate web app on the server (port 80).

I can add the gauge web parts OK to a web part page.  In the gauge designer when I enter values into the data souce for a database connection it always gives an error "Error: Cannot connect to data source. Error was:ConnectionString cannot be an empty string."  regardless of the type of DB Connection.

Additionally if I try to change the data souce to list or web part table,  the parameters required don't change and always stays on database parameters.

some screen shots attach

I suspect I'm doing something wrong, or maybe a permissions problem or something ?  Any pointers on where to look ?

Thanks

Hi,

Looks like a re-boot fixed it.  Not sure what was going on there, did an additional couple of IISReset's, but in the end looks like it needed the big on/off switch.

Cheers

Hello Dan,
Can you please check which is the build version you currently have (the version of the Nevron DLLs)?

By default, when you add a Nevron web part, it will have an empty connection. The first thing you need to do is to run the Chart/Gauge designer and connect to some data through the Data Source tab.

Following is a "Getting Started" video tutorial, which explains how to create a simple Bar chart connected to a SharePoint list: Nevron Vision for SharePoint Getting Started

Please, let us know if you have questions or if you meet any problems.

Best Regards,
