Hello, I’ve got a few questions about your Planner/Calendar control.

1. When I’m using the control with the CurrentView set to MonthRange I can’t seem to get the DaysOfWeek headers to not show. I have set the ShowDayOfWeek property to disabled within MonthSettings, but they still show. When I switch to SingleMonth view the days of the week disappear. Playing with the control I have come to find that that particular header is considered a MonthSubHeader, but I can’t find any docuementation on it. How do I go about making the days of the week be invisible in the MonthRange view, or set the MonthSubHeader invisible?

2. Reviewing your tutorials I see that you use CustomDrawElements.DayHeader, however in 4.4 I do not have this enum as an option. Did CustomDrawElements.CellHeader take it’s place?

3. In 4.4 I have found a way to custom draw into each day cell. When you test for CustomDrawElements.CellContents within the draw function, the e.Bounds matches the full day cell. I’m curious if it is possible to have such a thing for MonthRangeView for the MonthContents, or if it is already available? It would be handy to have this so I can access the bounds of the MonthCell when you’re in MonthRange view and use this to draw a summary string for how many items exist within that month. In this case the e.bounds would be the bounds of the MonthCell.

Ex:

private void calendar_Draw(object sender, CustomDrawArgs e)
{
if (e.Element == CustomDrawElements.MonthRangeMonthContents)
{
System.Drawing.Font f = new System.Drawing.Font("Microsoft
Sans Serif", 8F);

SizeF strLength = e.Graphics.MeasureString("Summary




//Gets the x location based on the month’s content width.
int x = (e.Bounds.Width - (int)strLength.Width) / 2;



//Gets the ylocation based on the month’s content height
int y = (e.Bounds.Height - (int)strLength.Height) / 2;

e.Graphics.DrawString("Summarynew
SolidBrush(Color.Black), x, y;

}
}

If this isn’t clear, please let me know and I’ll try and explain it better.

Mippy, thanks for the answers really appreciate you guys looking at this. I have 1 more question/possible request.

I’m using your control in MonthRange view and I’m having it show 3 rows of 4 months each. On each month it displays the total number of items that will happen within the month as I described in the above post. I then want the user to be able to double click on a particular month and it will drill down to a SingleMonth view. Currently I have tapped into DateClick event, and tested the clicks property for 2. This works fine as long as the user clicks on a cell that contains a date. Problem is if they click on an empty cell (Ex: Where padding days would be) no event fires. I’m curious if I’m missing an event or if it’s possible to add a click/double click event for the entire month cell.

Thanks again for your time.

Meppy,

Thanks again for the quick response, and getting a build out with these fixes. I’ve got a few more things for you and your development team. I’ll list them out here since we already have an ongoing thread instead of creating a new one. If in the future you would like me to split the suggestions and bugs up in their respective forums let me know.

1. The DateClick event is working how you described it, however this isn’t quite the correct fix. Problem I’m having now is my code within the click event is being fired twice. There isn’t a flag for the event specifying how I got into the event (Ex: MonthCell or DateCell click). This means I have no way of determining how I got into it, so I can’t test to make sure my code doesn’t get fired twice. It would be ideal if the developers could give us 2 separate events. One that fires for the date cell clicked, and one that fires for the month cell clicked. That way I can decide which I want to tap into depending on the view I’m currently looking at.

I believe this next one to be a bug, and I’ll try and describe it best as possible.

2. I’m currently looking at the calendar control in the MonthRange view. I have it setup to show 3 rows of 4 months each. I have set the ScrollInterval property to 12. I then set the calendar’s date property to 01/01/ {year I want to view}. This allows for me to view from Jan-Dec of the year I’m interested in. When you click the next button to jump to the next year it actually goes to Dec. of the year you were looking at to Nov. of the next year, instead of Jan. to Dec. of the next year. It behaves this way through 01/03/{year}, however at 01/04/{year} it works the way you would expect it to. One more interesting thing is on a leap year it is broken for only 01/01/{year} and 01/02/{year}, 01/03/{year} works fine.

After doing some testing and looking at the properties these are some examples. The dates below is what the calendar returned for the Date property.

01/01/2007 -> Click next -> 12/29/2007
01/02/2007 -> Click next -> 12/30/2007
01/03/2007 -> Click next -> 12/31/2007
01/04/2007 -> Click next -> 01/04/2008

Leap Years
01/01/2008 -> Click next -> 12/30/2007
01/02/2008 -> Click next -> 12/31/2007
01/03/2008 -> Click next -> 01/03/2007
01/04/2008 -> Click next -> 01/04/2008

01/01/2012 -> Click next -> 12/30/2007
01/02/2012 -> Click next -> 12/31/2007
01/03/2012 -> Click next -> 01/03/2007
01/04/2012 -> Click next -> 01/04/2008

Overall great control, and we will be buying it as soon as I can verify to my boss that it works the way we need it. Thanks once again for the timely responses.

It's me again got another one for you.

I'm currently viewing the calendar in MonthRangeView and there are 2 buttons at the top that allow you to scroll forward or backward. When I hover my mouse over one of these buttons it forces the Draw event to fire for the Calendar. I'm curious as to why this is.

I noticed this problem when I put calculations within the draw code for CustomDrawElements.MonthContents. The problem I was seeing was that the draw event being fired was preventing me from scrolling to the next set of months I wanted to view. Granted my current calculations are not optimized for testing purposes, but I don't understand why the event would be fired.

Further testing shows that at times your Draw event is being fired twice as many times as it needs to be. Example is I currently am viewing 12 months at a time, and the draw code gets fired 24 times. Also moving your mouse off of the scroll button fires the draw event as well. This could essentially result in numerous Draw calls if the user was to move their mouse rapidly on and off the scroll buttons.

Thanks again.

Hello,

I created a new form and added a calendar control to it to make sure what I'm seeing wasn't caused by some other code. With a very simple form I was able to recreate the draw situation. The following code is what I used.

private void TestDrawCal_Load(object sender, EventArgs e)
{
this.calendar1.CustomDraw = CustomDrawElements.MonthContents;

calendar1.Draw += new CustomDraw(calendar_MonthRangeDraw);
}

private void calendar_MonthRangeDraw(object sender, CustomDrawArgs e)
{
if (e.Element == CustomDrawElements.MonthContents)
{
//Listbox I'm using to display events
this.lbEvents.Items.Add(DateTime.Now.ToShortTimeString() + " - Draw fired");
}
}

I only changed 1 property and that was "this.calendar1.CurrentView = MindFusion.Scheduling.WinForms.CalendarView.MonthRange;"

The event is being fired as soon as I move my mouse over the bounds of the scroll button.

Also have another question, I can't seem to find an event to tap into to know when the user has pressed one of the scroll buttons. In this example they scroll forward 12 months or backwards. I'd like to be able to know when they do this so I can perform calculations on a 12 month range.

Thanks as always.

Hey again. Got pulled off our calendar project for awhile, but now I'm back at it. I was curious if you guys were ever able to recreate my problem from above. I'm still experiencing the problem, and have been trying to debug what's making the call to the draw code. I was curious if there is a way I can make a sample app and send it to you so you can see exactly what I'm doing. Thanks again.

I am using the newer versions of the control from above that fixed the bugs I reported. I would guess that these builds are tweaks to the build that is released with the file you just linked. With these builds I am seeing the problem persist. What is the best way for you to get my zipped test solution so you can see what I'm refering to?

I received your sample and experimented a bit with it. However, I am trying to move the mouse on and off the navigation buttons, but the event never fires. I welcome any further suggestions about how to reproduce this problem.

Thank you,
Meppy
