I have a DatePicker
custom control that I am trying to add to toolbox. The name of the file is BasicFrame.WebControls.BasicDatePicker.dll
and I go through the procedure of right click in Toolbox > Choose Items and then selecting the file after browsing to it under .NET Framework components.
I however get this error message:
There are no components in that can be placed on toolbox
Why do I get this message and how can I resolve it?
In some cases you can solve this problem with drag and drop:
