Forms :: Textbox Validation - Input Number Between 1 To 12

Private Sub todayMonth_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles todayMonth.Validating
Dim tb As TextBox = DirectCast(sender, TextBox)
If Convert.ToInt32(tb.Text) >= 1 And Convert.ToInt32(tb.Text) <= 12 Then
tb.Tag = True
[Code] .....
Actually, I wanted to validate the todayMonth textbox just to input number between 1 to 12. The problem comes out when I do this procedure : Lets say I input an interger 11 and it passes the validation and proceed to another textbox. Then I click back to the todayMonth textbox, it shows this error :
"Conversion from string "" to type 'Integer' is not valid."
I don't know why my value in the textbox is "null" or empty . I still saw the value 11 on the textbox.

View 1 RepliesAsp.net - 4.0 Framework Request Validation Will Not Allow Code-behind To Htmlencode Textboxes?
Jan 8, 2011I have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.
This is the code I have so far.
Session("RequestID") = Server.HtmlEncode(txtRequestID.Value)
Session("FirstName") = Server.HtmlEncode(txtInstFirstName.Text)
Session("LastName") = Server.HtmlEncode(txtInstLastName.Text)

View 2 RepliesShow A Summation Sign With The Top Portion Of The Summation Close To The Greek Sigma?
Dec 12, 2011I would like to show a mathematical summation in a rich text box, using the standard mathematical notation that shows a Greek capital sigma, with the starting value of n below the sigma and an infinity sign above it. I have successfully done this using the code below, but I cannot get the infinity sign closer to the sigma. It looks like it is not part of the summation notation.
Does anyone have an idea how I can get the infinity sign lower? When I use a character offset to lower it, it also lowers the lines below it, so that the distance between the infinity sign and the sigma remains unchanged.
