What is the solution for "The Type or namespace 'AjaxControlToolkit' could not be found..."?
asp.net, c#, database, javascript, textbox
Solution
Way to reference a `dll` is:
- In Solution Explorer, select the project.
- On the Project menu, click Add Reference. The Add Reference dialog box opens.
- Select the tab indicating the type of component you want to reference. (If you don't find your .dll in the list, then go to the browse tab and find it in your directory)
An article on MSDN to include installed libraries.
And there is another way to do it, too.
