View 2 RepliesI've added a simple SqlDataSource to my site with insert properties. I've also created some code behind to capture the insert command (oninserting="SqlDataSource_NewsLetterSubscription_Inserting").
Thing is how do I actually trigger the command to 'insert' from a standard button?
<asp:SqlDataSource ID="SqlDataSource_NewsLetterSubscription" runat="server"
Im using Entity framework with POCO entity generator template + SQL Server. I have mapping to stored procedure that takes two floats as input.
After executing function from code with two doubles as parameters: 1.23 and 4.56, SQL Profiler shows:
exec storedProcedureName @arg1 = 1,23, @arg2= 4,56
This is causing an error because it looks like that stored procedure takes 4 arguments, but it should take only two and there should be dots insted of commas in these floats.

I am using C# for ASP .NET 2.0. On my web form I have a TextBox that I want to let the end-user type inside of. The rules are as such: They should only be allowed to type numbers and a decimal. No negative numbers allowed. The number has to range from 0.00 to 24.00 - for hours - and can only allow for quarter hours - example: 0.00, 0.25, 0.50, 0.75, 1.00, 1.25, etc. Do I need a custom validator for this? If so, I do I check to see that the number is valid?
View 5 RepliesI have a registration page with some validation control. There is also a label that is invisible by default. When I click on a button and the page is valid the data is inserted to the database, the label becomes visible (there is text something like: The data has been inserted) and the textboxes become clear so the user can insert another row to the database. Now when I click on the button again and the page is not valid, I get some message kind of insert the name but the label with the text The data has been inserted stay visible. How can I hide the label when the page is not valid?

DateTime WCRDateTime = new DateTime();
WCRDateTime = DateTime.ParseExact( WCRDate + " " + WCRTime , "dd/MM/yyyy hh:mm" , new CultureInfo("en-GB",true));

LbCalendarCurrentMonth.Text = startingDate.ToString("MMMM");
