MessageBox => StylableMessageBox

With the StylableMessageBox, you can create forms similar to MessageBox but the handling is a bit different as we allow you to style the form before showing.

Let's create a message box first:

StylableMessageBox mBox = StylableMessageBox.BUILDER
                .WithTitle("This is a text", MessageBoxIcon.Information)
                .WithText("This is an example of a stylable MessageBox")
                .Build();

This will create a message box with a title and a message and - as we did not provide other information - an OK-button. Now, let's style the form as we want to: mBox.StylableControls.Text.ForeColor = Color.Red; At last, you can show the dialog using mBox.ShowDialog()

Note: If you change the size on the controls (e.g. increase the font size), please call UpdateSize() to update the UI to the new settings. Otherwise, the Ui may look weird.

Interaction.InputBox => StylableInputBox

With the StylableInputBox, you can create forms similar to VB.NETs Interaction.InputBox but the handling is a bit different (as it's practically a slightly different StylableMessageBox). Therefore, we allow you to style and adjust the form before you show it.

Let's create an input box first:

StylableNumericInputBox iBox = StylableNumericInputBox.BUILDER
                .WithTitle("Numeric Test", MessageBoxIcon.Information)
                .WithText("Please enter a random number between -100 and 100")
                .WithHelpButton(new Uri("https://github.com/Assorted-Development/winforms-stylable-controls"))
                .WithTimeout(TimeSpan.FromSeconds(30), DialogResult.Cancel)
                .ForNumericValue(0, -100, 100);

This will create an input box for numeric values (currently, we support text via TextBox and numeric input via NumericUpDown). Now, let's style the form as we want to: iBox.StylableControls.Text.ForeColor = Color.Red; At last, you can show the dialog using iBox.ShowDialog() and either use its DialogResult or iBox.Value to get the input entered by the user.

Note: If you change the size on the controls (e.g. increase the font size), please call UpdateSize() to update the UI to the new settings. Otherwise, the Ui may look weird.
