Partial classes

Hello,

I made a test project to understand how adding my own partial class to a
form works. It wasn't so easy. I guess it would get easier after I get used
to it.

My question: Why does a partail class for a form not nest itself under the
main form class the way the default partial class (Form1.Designer.cs and
Form1.rsex) does?

I get this...
Form1.Bindings.cs
Form1.cs
Form1.Desinger.cs
Form1.resx
Click to expand...

Instead of getting this...
Form1.cs
Form1.Bindings.cs
Form1.Desinger.cs
Form1.resx
Click to expand...

Am I doing something wrong?

Hi Douglas,

This is basicly a VS IDE issue instead of being controlled by .Net Winform
designer, so you'd better post in microsoft.public.vsnet.ide newsgroup in
future.

Anyway, this is actually an undocumented feature of VS IDE. If you use
notepad to open the project file [XXX].csproj, you can find the snippet
like this:

<ItemGroup>
<Compile Include="Form5.cs">
<SubType>Form</SubType>
</Compile>
<Compile Include="Form5.Designer.cs">
<DependentUpon>Form5.cs</DependentUpon>
</Compile>
<Compile Include="Program.cs" />
<Compile Include="Properties\AssemblyInfo.cs" />
<EmbeddedResource Include="Form5.resx">
<SubType>Designer</SubType>
<DependentUpon>Form5.cs</DependentUpon>
</EmbeddedResource>
<EmbeddedResource Include="Properties\Resources.resx">
<Generator>ResXFileCodeGenerator</Generator>
<LastGenOutput>Resources.Designer.cs</LastGenOutput>
<SubType>Designer</SubType>
</EmbeddedResource>
<Compile Include="Properties\Resources.Designer.cs">
<AutoGen>True</AutoGen>
<DependentUpon>Resources.resx</DependentUpon>
</Compile>
<None Include="Properties\Settings.settings">
<Generator>SettingsSingleFileGenerator</Generator>
<LastGenOutput>Settings.Designer.cs</LastGenOutput>
</None>
<Compile Include="Properties\Settings.Designer.cs">
<AutoGen>True</AutoGen>
<DependentUpon>Settings.settings</DependentUpon>
<DesignTimeSharedInput>True</DesignTimeSharedInput>
</Compile>
</ItemGroup>

These XML style attributes tell the VS IDE how to treat and open various
source *.cs files in the IDE designer. For example, <SubType>Form</SubType>
tells the IDE to launch form designer to view&edit the *.cs file. While
<DependentUpon>Form5.cs</DependentUpon> tells the IDE to place the current
*.cs item nested under "Form5.cs". So I think <DependentUpon> is what you
wanted.

Thanks.
