Web Forms :: Cannot Convert 0001 To An Int And Increment And Convet Back?
Jun 17, 2010
I have a primary key in a database that I present to the user.the key is made up in the format SUBJ0001 and needs to increment to SUBJ0002 etc as new entries are made. I have currently presented the user with the last entry and am relying on them to increment this value in a text box. How would i go about incrementint this through code.i could split out the SUBJ part but I cannot convert 0001 to an int and increment and convet back?
I know it sounds crazy, but yes, I am hoping to convert a site that was developed for 3.5 back to 1.1. In Visual Studio, I can target the output to 2.0, but that's as far back as it goes. I assume there is some way to do this, but I've been up for too long to even begin to think clearly and the only info I can find by searching here or google is for converting from old to new, not the other way around.
I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d; var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"}; if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d)) { lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text }
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.

I have a masked edit extender extending a text box. I enter the date 01/01/0001 then change a selection on a drop down list inside the same update panel with the autopostback property set to true. The date is changed to 01/01/1910.

I have a Model "News_Item", bound to an MSSQL table, with a couple of DateTime fields, "Creation_Date" and "Modified_Date"; whereCreation_Date and Modified_Date is set to DateTime.Now on creation, and Modified_Date is updated to DateTime.Now each time it is edited.
I can add new News_Items to the database, via my UI, fine. When I come to edit one and submit the form, it throws a "System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM" error. Checking the Creation_Date of the edited News_Item received by the POST Edit action in my controller, it comes up as "01/01/0001 00:00:00".What do I need to do to retain the existing Creation_Date?my Model:

I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?
