When i load the excel data into dataset using datadapet.fill method, It shows empty cell value where invalid dates are present. I want to show the error of invalid date.
View 4 RepliesI am currently storing empty dates in MySQL as 0000-00-00. I am then using a repeater with <%# Eval("check_in_date") %> to output the date to the page.
ASP.NET does not seem to recognise 0000-00-00 and converts it to 29/12/1899.
I would like it to be treated as empty therefore output an empty string to the page. Is there a way to do this?

View 3 RepliesI have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

If i have three textboxes in my vb.net webform.
Textbox1.text="Sumit"
Textbox2.text="4-Dec-2010"
Textbox3.text="1-Jan-2011"
I want if dates selected are in between textbox2 dates and textbox3 dates then textbox1.text="sumit" else textbox1.text="No dates"
I need some pointers to start on this.We are building a time off application where three instances of a calendar control will be displayed ( prev - current and next month) now users can click on various dates accross all three instances and then a count of number of days should be diaplyed in the parent textbox.
To begin with this, i started with adding the dates clicked by the user in Calendar2_SelectionChanged method into a list<> so that i can get the all dates user clicked and then add it to calander's selected dates collection. But this throws an e" object reference not set" error.
Is there anyother way to get all the dates that user click onthe calendar( note the dates doesn't get highlighed so seleteddates doesnt work)does anyone has a good example for this.

View 2 RepliesI am generating multi-series graphs with the date along the X-Axis. The problem is that not all of the series in the graph have the same dates in the date range. Meaning that if I choose 1 Feb through 30 Apr that one series may have data that starts at 1 Feb but only goes through the end of March but another series may have data for the entire date range. This skews the charts I need to create. Go, given the date range taken at the begining of the query I'd like to generate a list of dates and populate the data to be graphed, padding those series with 0's for those dates that have no data.
