我在TabBox控件中的GroupBox中有10个TextBox。如何实现剪切,复制和放大粘贴所有TextBox而不单独访问每个TextBox
答案 0 :(得分:0)
只需使用阻止或替换剪切,复制,粘贴命令的自定义文本框:
public class MyTextBox : TextBox
{
private const int WM_CUT = 0x0300;
private const int WM_COPY = 0x0301;
private const int WM_PASTE = 0x0302;
protected override void WndProc(ref Message m)
{
switch(m.Msg)
{
case WM_CUT:
// Handle Cut
return;
case WM_COPY:
// handle copy
return;
case WM_PASTE:
// handle paste
return;
}
base.WndProc(ref m);
}
}
