I have datagridview with paging enabled. But when I want to move from page to another page in the grid, then it only works when I press the 2nd time on some other page. I read some on the internet that I need to bind the data of the gridview but the thing is, I cant bind the data again because the gridview was filled with data in the page_load from querystring and I dont really want to go over the querystring again in the PageIndexChanging function.
Here is part of my code. The commented portion is the logic in which i am trying to implement. I want client side validation to be done and checked to see if it is correct format (MM/DD/YYYY).
I have 2 fields being displayed in a Gridview, StartTime, EndTime. I want to create a 'Time" column which shows the elapsed time in HH:MM format. (StartTime - EndTime) This was all generated with VS2008, table is pulled from an SQL Query.
I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
But it tells me:Exception Details: System.FormatException: Input string was not in a correct format.I think the problem might be that I'm use TIME form in SQL 2008 and maybe its expecting a long date/time format, maybe? But in any case it still should format at time, right?
Sometimes I get a datetime with a time sometimes it's just the date. Of course if it's just the date I I want to format with "dd.MM.yyyy" and if it has a time "dd.MM.yyyy HH:mm".. This is in a repeater, so I thought may be it's possible without a simple if statement?
I have time, for e.g 33 hr 40 mins 50 secs . i would like to convert it to a date time format.
for e.g I have used Convert.ToDateTime("33:40:50"), but in this case when you converting to date time, hour should be less than 24, otherwise it will fire an exception.
I have time data coming from database as '081500' for 8.15 am. Now, in the asp.net display, i need to format it as 08:00. I do not need the millisecond. I tried by using DataFormatString
In my application i need the time format the text box should accept as hour as 0 to 24,minute as 0 to 60 and second as 0 to 60.so when i will give hh:mm:ss then it will take 0 to 24:0 to 60:0 to 60 only not more then that.
I'm trying to make my string a nice formatted time but the column in the database isn't set up as a date/time field is there anyway I can do this? Here's my query
Dim query as String = "Select * from openquery (devbook, 'SELECT wb.arrival_time FROM web_bookings wb ')"
I have searched a few pages on this (including MSDN) but have not quite reached a solution. I need to convert "16/04/2010 22:39:06" to "2010-04-16 22:39:06.034" (for example).
I have already written an SQL function to do this, but would rather do this in VB.NET if possible. The date value is coming from the Date Created information of a newly uploaded file:
I have an application in asp.net which worked fine untill recently when i changed the datetime format in Regional and Language Settings in Control Panel.The date time format was default when i installed XP. I chose Indian standard time while installing XP.I changed the date time format to dd/MM/yyyy HH:mm:ss. And my application started to throw an exception whenever i tried to insert any datetime in to the table.The exception i get is:System.Data.SqlClient.SqlException: Error converting data type varchar to datetime.
