Custom event not added to event section of properties panel
This is visual c# so I'm not sure if this thread should go here.
I am attempting to add a custom event to the event section of properties panel for my custom control. The problem is no event is being added to the panel for me to subscribe to.
I attempted to create the event with,
Code:
public event System.EventHandler PositionChanged;
and then built the solution but still no event appeared in the panel.
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace LabelTextBox
{
public partial class ctlLabelTextbox : UserControl
{
public enum PositionEnum
{
Right,
Below
}
private PositionEnum position = PositionEnum.Right;
private int textboxMargin = 0;
private string labelText = "";
public event System.EventHandler PositionChanged;
public string LabelText
{
get { return labelCaption.Text; }
set
{
labelCaption.Text = labelText = value;
MoveControls();
}
}
public string TextboxText
{
get { return textBoxText.Text; }
set
{
textBoxText.Text = value;
}
}
public PositionEnum Position
{
get { return position; }
set
{
position = value;
MoveControls();
}
}
public int TextboxMargin
{
get { return textboxMargin; }
set
{
textboxMargin = value;
MoveControls();
if (PositionChanged != null)
PositionChanged(this, new EventArgs());
}
}
public ctlLabelTextbox()
{
InitializeComponent();
}
private void ctlLabelTextbox_Load(object sender, EventArgs e)
{
labelCaption.Text = labelText;
Height = textBoxText.Height > labelCaption.Height ? textBoxText.Height : labelCaption.Height;
MoveControls();
}
private void ctlLabelTextbox_SizeChanged(object sender, EventArgs e)
{
MoveControls();
}
private void MoveControls()
{
switch (position)
{
case PositionEnum.Below:
textBoxText.Top = labelCaption.Bottom;
textBoxText.Left = labelCaption.Left;
textBoxText.Width = Width;
Height = textBoxText.Height + labelCaption.Height;
break;
case PositionEnum.Right:
textBoxText.Top = labelCaption.Top;
if (textboxMargin == 0)
{
int width = Width - labelCaption.Width - 3;
textBoxText.Left = labelCaption.Right + 3;
textBoxText.Width = width;
}
else
{
textBoxText.Left = textboxMargin + labelCaption.Width;
textBoxText.Width = Width - textBoxText.Left;
}
Height = textBoxText.Height > labelCaption.Height ?
textBoxText.Height : labelCaption.Height;
break;
}
}
private void textBoxText_KeyDown(object sender, KeyEventArgs e)
{
OnKeyDown(e);
}
private void textBoxText_KeyPress(object sender, KeyPressEventArgs e)
{
OnKeyPress(e);
}
private void textBoxText_KeyUp(object sender, KeyEventArgs e)
{
OnKeyUp(e);
}
}
}
I downloaded the source code for this since it is from a book and the source code didn't have the a event handler for the event and the event wasn't in the event section of properties for the custom control.
