Problem description:
Select the Documents tab in the document library of SharePoint 2010 and select the upload document drop-down menu. You will find that the upload multiple documents button is gray and cannot be used.
When you hover the mouse over the button, a message saying:This control is currently disabled. You might not have the right permission level to use this, you might need to select an object or item, or the control might not work in this context.
This information indicates that the space is disabled. You may not be authorized to use this function. You may need to upload files one by one or the space is unavailable in the current context. It's a confusing reminder ..
Solution:
First, make sure that you are using IE. This function is the same as open with explorer and can only be used in IE, because chrome and Firefox do not have ActiveX space.
In addition, the IE browser you open must be a 32-bit version, not a 64-bit version. In Windows 7, two versions of IE usually exist.
There is a problemBackground SolutionThe SharePoint administrator selects enable additional actions and online status for members in the general setting of the current web application through the central administration. The specific steps are as follows:
1. Open Central Administration
2. Click Manage web applicatin.
3. Select the web application name you want to configure
4. Select general settings in the toolbar at the top of the page
5. In the person name actions and presense Settings area, find enable additional actions and online status for members and select Yes
6. Click OK to exit
7. Clear cache in IE, open the page again, and try again
Of course, in an enterprise, the above process may take a long time, so it is not worth waiting too long for users. At this time, there is a simple workaround.
Find the Datasheet view button in the library tag, click it, and return to standard view. You can use the upload multiple documents feature again... It's cheap.
