How To Hide the SharePoint 2010 Web Part Checkbox
This morning I came across this post in the SharePoint 2010 forums. Although it’s nothing critical, it’s good to know the workaround!
Issue
How to hide the checkbox that is available for each Web Part in SharePoint 2010.
Resolution using CSS
Add the following CSS to your Master Page
.ms-WPHeaderTdSelection
{
display: none;
}
Resolution using OOTB available options
- Display the Web Part without a title
- Add a Content Editor Web Part right before the list Web Part, adding the title of the List Web Part to the Content Editor Web Part.
Can this be done with code?; For example when the webpart is loaded
I dont like the idea of touching SP2010 Master pages!
I am sure it can be done!
I am a no code guy 
The other option is to use jquery to use the plain cell css instead. this removes the hover and the checkbox
