There are minimal permission requirements to view ComponentOne Web Parts in SharePoint. One of the following must be true:
OR
Additional permissions are needed for users to edit and save Web Parts:
Users must have Contribute permission or greater on the SharePoint site. (They must belong to the Home Members or Home Owners group on the SharePoint site, where Home is the name of the site. )
In order to grant certain users limited permissions:
Users who are members of the Home Visitors group are only granted read permission and, therefore, have limited functionality. Home Visitors can modify Web Part properties but cannot save them. Additionally, Home Visitors do not have permission to browse subsites in SharePoint, so subsites will not be accessible in the Data Source tab of the On-Board Designer. However, SharePoint administrators can change the default SharePoint permissions of the user groups.
Click the Check Names button to find the user or group, which will appear in the text box once it is located.
Click OK, and you will notice the user or group now appears in the Members list in the WSS_WPG Properties dialog box.
Click OK again to close the dialog box. The user or group will now be able to view ComponentOne Web Parts.
You can also choose to Give users permission directly. Select the control option for the user here. Users must have Contribute permission or greater in order to edit ComponentOne Web Parts.
