subclass datagrid control
Alex Feldman
should have been there in the first place). I have followed
instructions, similar to the ones in the following link that teach how
to subclass controls,
http://support.microsoft.com/default.aspx?scid=kb;en-us;311317
but once I replace the control initialization statements to initialize
to my subclass, the grid disapears from the designer. I guess I can
live with it since If I want to get it back I can uncomment the original
grid initialization if I want to edit the grid from the designer, and
then change the initialization back to a subclass when I'm done, but
isn't there a better way? I tried making the subclass a control
selectable from the toolbox, but it's greyed out when I add it. I
couldn't find a set of good instructions on how to get that to work.
If anyone has good instructions on how to subclass a DataGrid and make
it a selectable control from the toolbox, or just any other suggestion
how I can solve the problem described above I would greatly appreciate it.

All of these examples seem to do a lot of drawing of the control. Do I
have to implement my own OnPaint code, or any other display
functionality? I was thinking of inheriting from the DataGrid control,
so can't I just let the DataGrid do the painting?
Thanks.

> or any other display functionality?
important thing to note is that you need two assemblies - one for runtime
and one for design-time. The design-time assembly is usually built by hand
(command line, batch file). The assemblies are "linked" through VS using the
RuntimeAssemblyAttribute.

What am I doing wrong? I tried doing just an override overload, or just
an overload, but still got errors. The override worked just fine when I
was subclassing within my application. Also, I based the .BAT file on
the C# compiler example, so I modified it the best I can, but I'm not
sure that it's 100% right.
Thanks for the help.

When you say "restructure your code", do you mean just the custom
control code? If it's just the custom control code that needs to be in
C# while the application using the control can be in VB.NET that's not a
problem for me. Rewriting the application that would use this control
to be in C# however is not an option.
Thanks again!

compiler in version 1.0 of the CF. I believe that the general idea is that
the VB compiler throws errors/warnings that can't be suppressed during a
"design-time build", whereas the C# compiler can suppress these
errors/warnings. The alternative at this point is to not have a design-time
version of your control, instead create it manually through code, or you'll
need to restructure your code in the C# language.

I've got the 2 dll files that I copy to their appropriate locations.
However, when I add the customized DataGrid control to the toolbox it is
greyed out. I've checked the references in both projects (custom
control and user of control), and there doesn't seem to be anything
missing (as far as I can tell anyway). Do you have any suggestions? I
think I'm almost there!
Thanks.

the RuntimeAssemblyAttribute? Are you sure that you properly built the
design-time assembly against the CF designer assemblies and the desktop
assemblies? When you added the control to the ToolBox did you browse to the
design-time assembly?

Only the custom control would need to be rewritten in C#. You can consume
this control, even through the designer, with a VB.Net project.

I've looked at your thread before. I was actually missing the
/r:"C:\Program Files\Microsoft
Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Windows.Forms.DataGrid.DLL"
line in my .bat file. I just added it and recompiled. The control is
still greyed out :-(
Alex
Tim Wilson UNDERSCORE AT PERIOD
library project and built it to produce the CustomControls.dll runtime
output. Then I modified the batch file as shown below...
csc /noconfig /define:NETCFDESIGNTIME /target:library
/out:design.CustomControls.dll AssemblyInfo.cs DataGridPlus.cs
/r:"C:\Program Files\Microsoft
Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Design.dll" /r:"C:\Program Files\Microsoft
Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows

Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Windows.Forms.DataGrid.dll" /r:"C:\Program
Files\Microsoft
Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows
CE\Designer\System.CF.Drawing.dll" /r:System.Windows.Forms.dll
/r:System.Drawing.dll /r:System.dll /nowarn:1595
copy /y design.CustomControls.dll "C:\Program Files\Microsoft
Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows CE\Designer"
copy /y bin\debug\CustomControls.dll "C:\Program Files\Microsoft
Visual Studio .NET 2003\CompactFrameworkSDK\v1.0.5000\Windows CE"
Then I added the control to the ToolBox by navigating to the design-time
version (design.CustomControls.dll). The control appears in the ToolBox as
it should, I could drag and drop it onto the Form, and the associated
runtime assembly was automatically added as a reference.

form, and delete the old one. Then I rename the new grid to the old
one's name. Lastly, I can add the
Me.dgGridName.TableStyles.Add(Me.DataGridTableStyle1) to the
"DataGridName" section of InitializeComponent method, and all the column
configuration is saved that way. If anyone has a better way I'd love to
hear it :-)

you can then just search and replace "System.Windows.Forms.DataGrid" with
the fully qualified name of your custom DataGrid "<namespace>.<classname>".
That should allow you to do substitution.

(runtime) reference to be added automatically by dragging and dropping an
instance of your custom DataGrid from the ToolBox. That way the appropriate
design-time reference will be added to the project file as well. Then you
can just delete that instance that you just added. So you're basically using
VS to set up the references for you by dropping your control onto the form
through the designer. After that then you can go into the source and search
and replace like I mentioned. Since you're deriving from the DataGrid,
everything that you have done through the designer against the CF DataGrid
will be able to be done against your custom DataGrid.
