Simplify.Windows.Forms

Simplify.Windows.Forms Documentation

Provides additional System.Windows.Forms controls and helpers: message boxes, control validators, a list view column sorter, a nullable date-time picker, and a topmost progress bar.

Available at NuGet as binary package

Targets net6.0-windows, netcoreapp3.1, and net48. Depends on Simplify.Resources for string-table-based messages.

MessageBox

// Shows a message box with the given text, icon and buttons.
public static DialogResult ShowMessageBox(string text,
    MessageBoxIcon icon = MessageBoxIcon.Information,
    MessageBoxButtons buttons = MessageBoxButtons.OK);

// Shows a message box with text loaded from a string table (resource) record.
public static DialogResult ShowStMessageBox(string stringTableRecordName,
    MessageBoxIcon icon = MessageBoxIcon.Information,
    MessageBoxButtons buttons = MessageBoxButtons.OK);

ControlsValidator

Validates a list of controls for a filled/existing value, enabling or disabling a result control accordingly.

// resultStatusControl is enabled/disabled based on the validation of checkItems.
public class ControlsValidator(Control resultStatusControl, params Control[] checkItems)
{
    public void EnableValidation();
}

Usage Example

var validator = new ControlsValidator(buttonOk, textBoxName, comboBoxCity);
validator.EnableValidation();

TextBoxesValidator

Validates a list of TextBox controls for a filled value, with optional invalid-value color highlighting.

public TextBoxesValidator(Control resultStatusControl, params TextBox[] checkItems);
public TextBoxesValidator(bool enableColorHightlight, Control resultStatusControl, params TextBox[] checkItems);

public void EnableValidation();
public void DisableValidation();

// Text-box numeric value validation event handler.
public static void OnTextBoxNumberValidated<T>(object sender, CancelEventArgs e);

ListViewColumnSorter

An IComparer implementation for sorting ListView columns.

public class ListViewColumnSorter : IComparer
{
    // Number of the column to sort (defaults to 0).
    public int SortColumn { get; set; }

    // Order of sorting (e.g. Ascending or Descending).
    public SortOrder Order { get; set; }

    public int Compare(object x, object y);
}

Usage Example

listView.ListViewItemSorter = new ListViewColumnSorter { SortColumn = 1, Order = SortOrder.Ascending };

Controls

NullableDateTimePicker

A DateTimePicker that supports a null value.

public class NullableDateTimePicker : DateTimePicker
{
    // The text shown in the control when the value is null.
    public string NullValue { get; set; }

    // The nullable DateTime value of the control.
    public new DateTime? Value { get; set; }
}

TopmostProgressBar

A topmost progress bar Form control.

public partial class TopmostProgressBar : Form;
