Visual Studio Designer Cannot open a file Despite it being the first and only Class in the file

Whereas MSDN suggests that some incompatible behavior might also cause this issue
In my case, The incompatible behavior is caused by some possibly weird(messed up mappings) on Entity Framework.
I have done due diligence to ensure one-to-one correspondence between the data model and the EF model(even recreated it twice, ground up)
The project builds and runs when I comment out a certain section of code.
public partial class TestForm : SecureForm
{
private myEntities _db = new myEntities();
public TestForm()
{
InitializeComponent();
PopulateTestsList();
}
private void PopulateTestsList()
{
listViewTypes.Items.Clear();
var query = from q in _db.Types orderby q.TypeName select q;
foreach (Type dt in query)
{
ListViewItem lvi = new ListViewItem(new string[]
{
dt.TypeName
});
lvi.Tag = dt;
listViewTypes.Items.Add(lvi);
}
}
private void buttonAdd_Click(object sender, EventArgs e)
{
TestEditForm myEditForm = new TestEditForm(_db);
if (myEditForm.ShowDialog() == System.Windows.Forms.DialogResult.OK)
PopulateTestsList();
}
private void buttonEdit_Click(object sender, EventArgs e)
{
if (listViewTypes.SelectedItems.Count > 0)
{
Test tsdt = listViewTypes.SelectedItems[0].Tag as Test;
if (myEditForm != null)
{
TestEditForm myEditForm = new TestEditForm(_db, mysForm);
if (myEditForm.ShowDialog() == System.Windows.Forms.DialogResult.OK)
PopulateTestsList();
}
}
}
}
It still does not show up the designer.
Here's the designer.cs for reference

Code analysis shows that the form is missing,(MSBuild does not). MSBUILD compiles the form into an exe thats kinda defunct(on the broken entity)
The entity in question has Name & ID properties. Both Name and ID are mapped properly, The collection is pluralized and loaded into a list.

How to bind data to a custom Windows Form using SplitContainer?

I've created a form that I call a ListChooser. It looks like so:
It consists of a System.Windows.Forms.Button and .TextBox.
Clicking on the Button (shown above with the text "Fruits") causes a dialog to popup and some selections are made and the TextBox is populated, like so:
My problem is I can't figure out how to set a System.Windows.Forms.Binding to this TextBox. I think the complication is that it's not just a TextBox, it's 2 components in one. (I know how to data bind with just a standalone TextBox). If I go to the TextBox > Properties > DataBindings > Advanced > ..., All entries listed under Property are not selectable:
I've tried this which has no effect:
private System.Windows.Forms.BindingSource myBindingSource;
this.myBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.myBindingSource.DataSource = typeof(Foods) // Fruits is a Property of Foods;
myListChooser.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.myBindingSource, "Fruits", true));
How do I do this?

c# chart axis not displaying when form is loaded

For some reason the axis and grid is not being displayed on the c# chart. as you can see from the two pictures, the background of the chart is being displayed, but nothing else is. Can anyone help me figure out why the grid and information from the chart is not being displayed?

Your code works fine but you need to add a DataPoint to trigger the Chart's display.
This is most likely because without any data the automatic settings, which are default for most elements, including ChartArea's Size, have nothing to work from. I tried it and after adding even a dummy point the grid and all other nice details will show just fine..:
As you can see clearing the DataPoints will wipe out the chart again..
If you want your Series clean of dummy data you can either delete the dummy after adding the first data or add a dummy series..

Cannot view data

I have covered many tutorials and articles but can not find exactly what I need to assist me in resolving my issue.
My issue is that my compiled dll does not return rows of data from my SQL database file to the DataGridView.
I have created this project as a windows application for testing and it works fine. However, when I change the output to a class library it runs but does not return any data to the DataGridView. The header is there, because it is declared, but I have a feeling the compiled dll can not establish a connection to the database.
I have experience with C# and ASP but not in creating dll's.
To also clarify further, I can use the dataset or the bindingsource before I compile and view all the records using the Preview Data option. Is there a specific way you have to setup the database connection when creating a class library in my situation?
SQLDatabase.mdf Connection String:
Data Source=(localdb)\v11.0;Initial Catalog=SQLDatabase.mdf;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False
Designer Generated Code: this.itemsTableAdapter.Fill(this.abDataSet.Items);
Please let me know if you would like me to post the Form.Designer.cs which was Designer Generated Code as well. Again, everything works fine as a Windows Application but as a Class Library the rows of data are never displayed in the DataGridView.

You have to add code in your class library that will let you set the connection string. The place to set the connection string is in the constructor of your class library. You can manually add the connection string like this in the app.config:
<connectionStrings>
<add name="MyDB" connectionString="Server=.\SQLExpress;
AttachDbFilename=C:\MyFolder\MyDataFile.mdf;Database=dbname;
Trusted_Connection=Yes;" />
</connectionStrings>
Then access the configuration string like this:
var str = ConfigurationManager.ConnectionStrings["MyDb"].ConnectionString

GUI White becomes Transparent

I wrote a GUI Form in c#. When I executed the program, white color becomes transparent.
It's suppose to be like this:
But when I run, it's like that:
You can see that white color became black like the picture behind.

By setting the TransparencyKey of the form, transparency is enabled. Default color for transparency is white.
Remove this line from the InitializeComponent () function
this.TransparencyKey = System.Drawing.Color.Transparent;
and the white on your form will no longer be transparent.
