      {
          panel2.Controls.Clear();
          panel2.Controls.Add(obj);
          obj.TopLevel = false;
          obj.Show();
      }

Solution 1

Are these forms within an MDI container?

Either way you need to make the reference to the Calendar object (note the spelling :)) available within the context that it needs to be referenced. In this case that means the top level form, i.e.

class MyForm {
 ...

 Calendar calendar = new Calendar();

 void viewCalendar_click(object sender, EventArgs e){
   panel2.Controls.Clear();
   panel2.Controls.Add(obj);
   calendar.TopLevel = false;
   calendar.Show();
 }
}

Then you can refer to it in the event handler of 'Jump to Today':

void jumpToToday_click(object sender, EventArgs e){
  calendar.HighlightDate(DateTime.Today);
}

... obviously you need to write HighlightDate as well and that depends on how your Calendar works, but that should be pretty easy.

OP's comment:
I tried following code. But did not worked.

Collapse | Copy Code
private void viewCalenderToolStripMenuItem_Click(object sender, EventArgs e)
{
Calender obj = new Calender();
obj.TopLevel = false;

if (panel2.Controls.Count > 0)
{
panel2.Controls.Clear();
panel2.Controls.Add(obj);
obj.TopLevel = false;
obj.Show();
}
else
{
obj.TopLevel = false;
panel2.Controls.Add(obj);
obj.Show();
}
}

private void jumpToTodayToolStripMenuItem_Click(object sender, EventArgs e)
{
Calender obj = new Calender();
obj.monthCalendar1.SetDate(DateTime.Now);
}

That's because you didn't do what I suggested, you're still declaring Calenders (sic) inside each method.

'Calender' is name of other form on which there is 'monthCalender1'.
