I was using Visual Studio 2015 and the component BehComponent.dll to use Persian DateTimePicker and I right clicked on the ToolBox and chose Choose Item and then I selected this component and It generated the DateTimePicker Components in the ToolBox.
But after intalling a fresh windows and Visual Studio 2015, I did the same thing but I could not install this component.
There was a message that:
There is no component in BehComponent.dll to be placed on the ToolBox.
Although I could add this component as a reference but the component itself did not appear on the ToolBox.
It could easily be solved.
I created a
Windows Form Applicationand openedToolBoxand simply draggedBehComponent.dllon theToolBoxthenPersian DateTimePickerwas easily generated itself.
