Hello guys, please subscribe to my channel if my video help you. I will upload more tutorials and ideas.
What did you do at 9:20 ...what did you press to do thing you did?
@@Guide4Ever hello sir, i only deleted those panel i added inside flowlayout. i only added those panels to get thr right size of the usercontrol.
I will try to add commentary or text to my upcoming tutorials.
@@coding_ideas Thank you! :)
How to movie next year??
@@PradeepKumar-cq1dz What do you mean? Movie?
so instead of copying and pasting that entire method's code, you can just declare static variables at the top of the class for the form so that they are accessible like so:
static DateTime currentDT = DateTime.Now;
static int currentYear = currentDT.Year;
static int currentMonth = currentDT.Month;
and for the next button all you have to do is write these three lines:
("displayDays" is my method name for creating the user control by the way (where the two for loops are).)
dayContainer.Controls.Clear();
currentMonth += 1;
displayDays();
and finally for the previous button you can do:
dayContainer.Controls.Clear();
currentMonth -= 1;
displayDays();
then if you want the year to update after december just set a condition in the button click method for either button where if the current month is equal to 1 or 12 you can increment or decrement the year by 1.
private void DisplayDays()
{
int days = DateTime.DaysInMonth(currentYear, currentMonth);
DateTime startOfMonth = new DateTime(currentYear, currentMonth, 1);
int dayOfWeek = ((int)startOfMonth.DayOfWeek + 6) % 7; //monday start
for (int i = 0; i < dayOfWeek; i++)
daysContainer.Controls.Add(new dayBlock());
for (int i = 1; i
THANK YOU SO MUCH, I'VE BEEN LOOKING FOR SOMETHING LIKE THIS FOR A LONG TIME.!!
Thank you very much for this video. I have been trying to find a way to create a calendar such as this for a very long time. Please keep up the good work.
You're welcome ☺️. And thank you for watching my video.
Thank you for sharing the knowledge. keep up the good work!
Thank you!!! So informative.
THANK U!! u safed me!!!! it didn't work out for me at the beginning, but I removed +1 from the line, i found a my mistake, and everything came out! good luck to you! your videos are very good, I hope you will continue to do video lessons
what mistake did you have? Because I have troubles at the beginning :(
Great Tutorial!! Thank you bro!
Good video! Helped me a lot! But how did you get the individual dates into separate boxes?
Thank you made my day
thx for the video mate!
You can use this for error.
(button_click events)
(decrease)
if (month==1)
{
month = 13;
year--;
}
month--;
and
(increase)
if (month==12)
{
month = 0;
year++;
}
month++;
At some point in the program you want the 0 or 13th month name and we get the error.
aga merhaba bu kodu nereye yazıcaz tam olarak? bir de yazınca bu sefer ayları 2şer 2şer atlamaya başlıyo bunun çözümünü biliyo musun
@@felixandro1512 2 tane butonun var birisi ay'ı artırıyor diğeri azaltıyor. Ay değerleri de sayı olarak tutuluyor sen o sayının hangi aya denk geldiğini isim olarak alıyosun. Eğer bu belirttiğim kodu yazmazsan ay değeri 1 iken yani Ocak ayında sen Ay değerini azalttığında 0. ay diye bişe olamayacağı için program hata verir. Veya aynı şekilde tam 12. ayda iken sen Ay değerini artırırsan 13. ay yine hata verir. Bu kodu 2'ye bölüp birini ayı artıran butonun click olayına diğerini ay'ı azaltan butonun click olayının en üstüne yazarsan bu sorun çözülür. 2şer 2şer artmasının sebebi month-- veya month++ diye artıran bi kod daha vardır. Onu silmen gerekir benim yazdığım kod zaten kendisi artırıp azaltıyor. (decrase) yazan kod kısmı ay'ı azaltan butona (increase) yazan kod ay'ı artıran butona yazılacak.

Excelent!!, one question : How can I do to record appointments but for the entire series of a specific day?
when I open the code, instead of showing just a short section with Form1_Load, several sections appear, one for each panel I created, referring to the day of the week, why does this happen?

Hi! Very great video and helped me a lot with a project that I did. I was wondering if you could tell me or point me in the right direction on how to have a calendar for only week by week, instead of the whole month.
Hello, Thanks for watching. Im glad that it helped you. I havnt figure it out yet on how to create a calendar by week, if i have free time i can try to make one :). Just try to play with usercontrol class maybe it will help
Gracias me salvaste el día
You're welcome :), please subscribe to my channel :)
Great tutorial, not wanting to abuse it, but I would like to color the current day in the calendar and Sundays in red.
hello, Sorry for the delayed response.
declare a static variable for your month and year in your
main form, and assign a value.
example :
staticMonth = currentMonth;
staticYear = currentYear;
and in your UserControl Days.
create current date variable
example :
currentDate = MainForm.staticMonth + "/" + lbday.text + "/" + MainForm.staticYear;
and compare the currentDate and dateToday. if both are equal u can customize UserControl.
In this follow-up is a lot of work, thank you very much for your feedback.

For me the 31st date of the month is not show only till 30th
Any solution.
The months that end on a Saturday cause an issue. Next month starts on a Monday, instead of a Sunday. Any suggestions?
if anyone has the same issue, add the following before the daysOfTheWeek loop:
if (daysOfTheWeek == 0)
{
daysOfTheWeek = 7;
}

At 11:23 : Somehow it doesn't show the User Control stuff, but just the plain form with the names of the days of the week. Is there a way to fix it?
have a same problem, do you know how to fix it?
@@iredderpvp7094 Sadly no, it just doesn't work for me😢
Hi, I ran into this issue as well on my end and was wondering why this was happening. Turns out the Form1_Load method (where displayDays is being called) was not bound to the actual form... hence a blank form is displayed with no user controls, so displayDays is also never called. To fix this, you need to bind the form to the Form1_Load method under the Events section under the form's properties in the "Load" attribute. Then user controls will be displayed!
what you press in 9:19?
delete :)
Add source code, please...
Hello, great video, but i have a problem. For some reason my version doesnt show 31st(im doing this in december)
Do you know why?
for int i = 0
you put > instead of => i did the same
I am getting everything right! Except that it always starts from the top left corner (My Calendar starts with Monday), no matter which month it is!
Maybe you have a hint!
Hello, Have you added a blankUserControl and create a loop? And if u start your week with monday, try to remove the (+1) i added at thr dayofthrweek.
Good luck.
@@coding_ideas it works now, thanks for your support!
Your coding type is terrible, but for beginner its clearly to understand. but instead of using the same code block 3 times and have 2 exact same events for the buttons, i would create one Event for all buttons and let them access dynamically.
private void ForwardOrBackward(object sender, EventArgs e)
{
Button button = sender as Button;
switch (button.Name)
{
case "BtnNext":
month++;
if (month == 13)
{
year++;
month = 1;
}
break;
case "BtnBack":
month--;
if (month == 0)
{
year--;
month = 12;
}
break;
}
daycontainer.Controls.Clear();
DisplayDays();
}
private void Form1_Load(object sender, EventArgs e)
{
now = DateTime.Now;
month = now.Month;
year = now.Year;
DisplayDays();
}
void DisplayDays()
{
DateTime startOfTheMonth = new DateTime(year, month, 1);
LbMonth.Text = startOfTheMonth.ToString("MMMM").ToUpper() + " | " + year;
int days = DateTime.DaysInMonth(year, month);
int dayOfTheWeek = Convert.ToInt32(startOfTheMonth.DayOfWeek.ToString("d")) + 6;
if (dayOfTheWeek >= 7)
dayOfTheWeek -= 7;
for (int i = 1; i < dayOfTheWeek; i++)
{
UserControlBlank ucBlank = new UserControlBlank();
daycontainer.Controls.Add(ucBlank);
}
for (int i = 1; i
Hello Steven, Thank you for the comment . You're right, it seems terrible way of coding but the target of my videos is beginners. so that they can create beautiful applications with a simple and easy to understand method, and it is up to them to improve the method of coding. have a nice day and happy coding :)
I'm really confused about how you made "DateTimeFormatInfo" work.
Some commentary would really be useful, I hope you consider this. Well done on tutorial nonetheless.
Thank you :)
@@coding_ideas The subjects of your videos are excellent. I would live to learn this stuff from you. But, that requires that you actually explain what you are doing and why. Thare are already way too many "music"-tutorialls on CZcams, I just close and search for the reals ones with voice commentary. Please consider re-doing them with voice commentary instead.
how can i do this with a week view with time on the y axis, like a timespan which events get adjusted to

@Coding Ideas cant access the daycontainer function. How can we access that?
I apologize for the late reply. Daycontainer is the name of the flowlayout panel.
At 10:50 you type in daycontainer.Controls.etc.etc. Yet, I have followed your build to a T and and DayContainer doesn't exist. You have mentioned in only comments that it's in FlowLayoutPanel yet it isn't. I have built and rebuilt this calendar following your design. Is there a unique template that houses this Daycontainer. Please be a detailed as you can and say where/how exactly we can get daycontainer to work.
I apologize for the confusion. 'Daycontainer' is the name of my flowlayout. If 'daycontainer' does not exist in your project, please check the name of your flowlayout.
Removing and adding UserControls every time is bad for performance. In my calendar implementation (on the channel), all days are redrawn. This takes away the annoying flickering . 😋
can you share the code

what did u do in 9:17 ?
I just removed the panel i added :) . I only put those panels to get the right size of the usercontrol :) .
