Textbox - Validate Text Box Contains Integer Greater Than Equal To Zero?

Mar 29, 2010

If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?

Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?

Converting Decimal In A Label To An Integer?

Mar 28, 2011

Currently using VS2008, VB.NET, SQL. I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.

I am grabbing the field from the FormView as such:

Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)

I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.

What I have tried so far:

Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
Dim AvgTicket1 As Integer
AvgTicket1 = Double.Parse(AvgTicket.Text)
Do something with AvgTicket1

I have also attempted to Round the Value, then convert it and call it - no luck.

Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.

What are some methods I can successfully convert this value to an integer from a label?

How To Validate The Maximum Allowed Number Of Characters In A Multiline TextBox

Mar 30, 2010

it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)

DataSource Controls :: Decimal Values Not Updating With Decimal Places?

Apr 6, 2010

I'm trying to execute this statement every minute with SQL Agent, I have it set up as a job:


It's trying to update a column which data type is set to decimal. Just so you know what I really need out of it, here is an example:


The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
