Board index » Web Programming » [newbie]cant drop controls onto multiview

Web Programming349
Not sure what is going on. I added a multiview to my project and then

dropped 4 views. I cannot put any controls from the toolbox onto any of the

views. Instead they show up at the top of the document underneath the menu.

Cutting and pasting existing panels and controls from my document into the

views just puts them back where they came from. Typing into the view works

fine. I can type anything I want, just cant drop any controls.



Tell me I am doing something wrong. Surely I can drag and drop controls

onto a view?



Is there an idiot's guide to this madness? I had a bunch of grayed out

controls in the toolbox and it took me two weeks to figure out that the

first class in my dotnet program has to be "_default" and anything else

grays out the designer widgets.

Yes, you can drag and drop controls into a view.



Only one view can be visible at a time. This means that if you place

controls is say the third view from the top, when that view is visible it's

controls will appear at the top of the multiview - and if the multiview is

placed at the top of the page, that's were the views controls will show.



Is this maybe what you are seeing?

Thanks Mike, the multiview selections works fine. I have a menubutton for

each view and clicking on the menu selects that view. I just cant put

anything except text into the views. No controls, etc. The multiview is at

the bottom of the document. I did not design the project with multiview in

mind but added in the multiview when it was apparant that tabs (or

multiview) would be best.



I attempted to bring up the Default.aspx.cs[Design] page and it failed with

these messages:

===========from the Design page========

Object reference not set to an instance of an object.

======end of design=====

I did not have these error messages before adding the multiview and menu. I

then tried backtracking, removeing the views, multiviews, even the menu that

I added. I cannot get back to where the designer comes up. When I hit

rebuild, the project builds just fine, no errors. I do not see anything in

the above error to indicate how to fix the problem.. The designer page has

a couple of objects on it that I added and have not even used yet.



I just tried deleteing my DataSet1.xsd and that didnt help so I re-added it.

Looking at "Default.aspx.resx" that page has my pgSqlCommand1 and

pgSqlConnection1 Those were the two items I added to the designer page

which is not being displayed. I do not know what is going on. Previously

when the designed page failed to show up I saw a message about haveing a

class in the wrong place and that "_default" had to be the first class in

the project. I took out a small error class I had added at the top of the

Default.aspx.cs page and that fixed the problem and the pgSql connections

and commands showed up in the toolbox for the first time. Unaccountably, I

cannot get back to where I was before I started messing with the multiview

components.



Is there any way I can narrow down what is causing the problem? Since it

occures at design time I would assume that some static object like a

SqlConnection is no longer connected to a database and that is keeping the

page from coming up. If so, how do I delete "Default.aspx.cs [Design] so I

can start over. I cant delete Default.asps.cs as that has a lot of code.



Question: If I bring up my main page "Default.aspx" at the footer (of

VS2005 dev gui) I can selected between Design and Source. The Design at the

footer of VS2005 is a *DIFFERENT* design page than the one that is shown

when I select "Default.aspx.cs [Design]" at the header of VS2005. That

second "[Design]" page is the only page where I can add SqlCommands,

Connections, etc. I cannot add those widgets to the design page that has

GridView and SqlDataSource.

Two problems went away, one didnt even exist.



1. Selecting a view to drop a control does not cause the control to go

there. It appears at the top of the document and then I move it over the

view. I would have thought it would drop into the view (like a control

surface) and the view would expand to where the stuff I dropped in would

fit. I had to press return until the view got big enough then when I

positioned all the (existing) controls over the view they were hidden until

enabled. They were not attached to the surface of the view like I thought.



2. I had to delete Default.aspx.resx before the component designer would

come back up. This fixed whatever was causing this compile time error

message: "Object reference not set to an instance of an object".. The

object was never identified and I had no clue which one was causing the

problem so I just deleted that resx file and did a web site rebuild.

Possibly I had something in the .res file that had been deleted in the other

code pages????



The following is all that was shown and it appears the instant I selected

the component designer.

Anyway deleting that resx file fixed problem. The component designer came

up and I could add in the tools I need.
