Occasionally, a C# project will have a user control in it that belongs to another C# project and I will have to move it over. Attempting to simply copy + paste that user control over results in namespace errors. Let's say project 1 has a namespace of
namespace General.Category1.Controls and project 2 has a namespace of
The steps I initially took were:
1) Copy + paste control (which includes
.resx files) from project 1 to project 2
2) Change namespace to project 2's
At this point upon building, I received additional errors from the forms on which this control is used before the copy + paste that states
'The type of namespace name 'UserControl1' does not exist in namespace 'General.Category1.Controls' (are you missing an assembly reference?). It turns out that the
designer.cs form files did not update to the correct namespace after the copy + paste.
So then I add to add an additional step:
3) Change declarations to match new namespace of
private General.Category2.Controls UserControl userControl1;
I'm confused why the
designer.cs files wouldn't have updated that since it's not usually advised to edit
designer.cs files. But then again, maybe it's ok to modify them as long as you don't touch the
InitializeComponent() method as it states in the actual file itself.
In conclusion, why do all of the
designer.cs not update automatically? Is the actual answer to know where this control is used and update the declarations myself as I have done?
[EDIT]: The first 2 steps are for the control itself (it's
.designer.cs files). The 3rd step is for associated with any forms in which the control was placed on before copying it over because it is still using the old namespace, so all of the form
.designer.cs files must be changed as well.
how are you referencing the user controls is this a web app or windows app..? in it's a web app can you show how you are referencing it in the .aspx file..?
instead of copying and pasting them in repeatedly like that, why don't you make a control library project and reference that?
@MethodMan This is a Windows Application.
@Muckeypuck That's what we're doing, but there are two control library projects. The control was made in the 1st incorrect one, so I am copying + pasting it into the 2nd correct one.
something doesn't sound right. if you are pasting it into the second one, you should only have to paste it in once. i guess theres something i dont understand. Are you reproducing your control libraries for every project?
