Hi experts, I little help if i may.

I am using some code I found on the following web site:

http://www.syncfusion.com/faq/aspnet/search/257.aspx

I am using the c# example, my problem is that when I select a month from the drop down it changes the selected day in the calendar control and not the month.

Can any one see why, and if so, how to fix.

Regards

Wayne

i think that there is a difference between the format in the calender and the format you r using in the code....

one type of format: DD/MM/YY
the other maybe : MM/DD/YY..

so there will be a conflict between day and month..

hi tarek,

thank you for the quick response, however all i've done is cut and paste the code from the site, does it work for you?

i think here is the problem..:

DateTime dtNewDate;
 
dtNewDate =DateTime.Parse (Int16.Parse(ddlMonth.SelectedItem.Text) + "/1/" + Int16.Parse( ddlYear.SelectedItem.Text));
 
Calendar1.TodaysDate=dtNewDate ;

here you are using the format : MM/DD/YYYY
and your calender may be using : DD/MM/YYYY
and thus cosidering the day as month


good luck

ok stepped through the code and the dtNewDate is 09/01/2006 00:00:00, which does look like things are the wrong way around.

do you happen to know the code to switch it to 01/09/2006?

instead of playing with the format..
try to use  

dtNewDate=DateTime.Now;
dtNewDate.AddMonth(difference between the dropdownlist and DateTime.Now);

i mean if your current month is june... 06  

and you chose from the drop to  be august....
then the difference between them is 2...

just add this difference to DateTime.Now.AddMonth(difference)

it will add 2 to 06 and it will change to august..

did you get it..

DateTime dtNewDate=DateTime.Now;

int diff=int.Parse(ddlMonth.SelectedItem.Text)-int.Parse(DateTime.Now.ToString());

dtNewDate.AddMonth(diff);
Calendar1.TodaysDate=dtNewDate ;

int diff=int.Parse(ddlMonth.SelectedItem.Text)-int.Parse(DateTime.Now.ToString());

instead of DateTime.Now.ToString()

use DateTime.Now.Month.TOString()
