I have a legacy single form app and I wanted to add a few other forms to it.

So I add a form, an aboutBox to start off with, in the designer of the form I set the text property of various labels to what I want and I can see them change on the form design view. I then instantiate and display the form inside the click function of a button on the main form:

AboutBox1 aboutBox = new AboutBox1();
aboutBox.Show();

But then at run time the form appears with default placeholder text in all the labels - it completely ignores what I set in the designer?

CodePudding user response：

Did you try to set your content from code instead of from designer? About box shows default Application info from app manifest, on runing. Maybe it's a good way to create similar window by "Form" template.

In constructor default window AboutBox you can see this:

this.Text = String.Format("Information about {0}", AssemblyTitle);
this.labelProductName.Text = AssemblyProduct;
this.labelVersion.Text = String.Format("Version {0}", AssemblyVersion);
this.labelCopyright.Text = AssemblyCopyright;
this.labelCompanyName.Text = AssemblyCompany;
this.textBoxDescription.Text = AssemblyDescription;

This some lines is responsible to override your data after lauch. Change it and try again.
