A very easy one hopefully - what expression can I use to validate an integer to ensure it is greater or equal to zero, but less than 2,147,483,647 (i.e. the maximum value of an integer)?
For example 0 =< x < 2,147,483,648
i have textbox it should accept only integer or float values..........
View 1 Repliesi want to validate my password textbox that it should be minimum length of 7 charsthe code i m using is this
Code:
if (textbox1.text.legth>7)
{
label1.text=""valid";
}
else
{
label1.text="invalid";
}
now the problem is this is it everytime check when the page is postback i.e when ever page is return from server.
I'm trying to validate an integer range with a CustomValidator. The range is set dynamically, so when either the min/max values on my usercontrol change, the client validation function is updated. However, I can't get the validation function to fire. I have this code:
<asp:CustomValidator ID="vldAnswerValid" runat="server" ControlToValidate="txtAnswer" Display="Dynamic" SetFocusOnError="true" ValidationGroup="answer" OnServerValidate="vldAnswerValid_ServerValidate" Enabled='<%# !IsReadOnly %>' />
Setting the function from the codebehind with: vldAnswerValid.ClientValidationFunction = " function(oSrc, args){ alert(1); args.IsValid = false; } ";
But there's no message displayed and no alert. Am I missing something?
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)?
I am using below code to validate interger and float in asp.net but if i not enter decimal than it give me error
<asp:TextBox ID="txtAjaxFloat" runat="server" />
<cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" TargetControlID="txtAjaxFloat" FilterType="Custom, numbers" ValidChars="." runat="server" />
i have this regex also but its giving validation error if i enters only one value after decimal. [URL]
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.)

View 5 RepliesIn the standard forms authentication, users are identified by a Guid. I want to give my users an UserId of type int (doesn't have to be the primary key, just something to do lookup's on).
Is it safe to add an additional column to the aspnet_users table, or should I create a new table which FKs to the UserId column and has a Unique column which generates the integer ID?
The later sounds like a bad performance hit to take just for the sake of an int!
EDIT I want to create URLs like those on stackoverflow. eg.[URL] where the User ID is an int. For that reason I don't want to use Guids.
Is it possible to popup information according to the value of an integer,
