Asp :RangeValidator And Asp:RegularExpressionValidator Both Fired Simultaneously?
Feb 17, 2011
I have Asp:TextBox,Asp:RegularExpressionValidator and Asp:RangeValidator on .aspx page.
These two validators have ControlToValidate value equal to textBox Id.
RegularExpressionValidator have validation Expression such that it allows only number.
Range validator have maximum value ="100" and if I enter any text then both validators get fired .
Logically only RegularExpressionValidator should fire if I enter any textvalue.
Is there any property of Range validator such that it check for numeric value to compare and disbled if value entered in textBox is some text so that no handling of event(Client side and Server side both) is required.
I have an update panel in my ASP.NET web form with a trigger that will fire a click event when the contents within my update panel is updated (it's a grid view with fields). The event that is fired when then take the changes user made and do some calculation and then update another update panel with that information. This is all fine and dandy when the user tabs along the form and fill out the form in a orderly fashion before hitting any buttons on the page.
If a user accidentally hits another button on the page while changing the content in my grid within the update panel, for example, the user enter a value in my grid view control, without tabbing, the user click the save button. Logically, i believe that the trigger should fire the click event first (event A), and then the save button event (event B). But, consistently I haven't seen event A gets fire correctly while event B gets fire all the time. is there a way to ensure event A always gets fired before event B? also if event A update another update panel without the page will event B fire after the update is complete?
function LogInUser() { var LoginName = document.getElementById("<%=txt_LoginName.ClientId %>").value; var Password = document.getElementById("<%=txt_Password.ClientId%>").value;
A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
I have the below rangeValidator. However I would also like it to accept 999999,00 (seperated by a comma) I have found the following reg expression: ((d{1,2},)?(d{3},)*(d{3}))|(d+) but I'm not sure where to include this?
I am trying to reproduce a threading error condition within an HTTP Handler.
Basically, the ASP.net worker procecss is creating 2 threads which invoke the HTTP handler in my application simultaneously when a certain page loads.
Inside the http handler, is a resource which is not thread safe. Hence, when the 2 threads try to access it simultaneously an exception occurs.
I could potentially, put a lock statement around the resource, however I want to make sure that it is infact the case. So I wanted to create the situation in a console application first.
But i cant get 2 threads to execute a method at the same time like asp.net wp does. So, my question is how can you can create 2 threads which can execute a method at the same time.
Edit:
The underlying resource is a sql database with a user table (has a name column only). Here is a sample code i tried.
[TestClass] public class UnitTest1 { [TestMethod] public void Linq2SqlThreadSafetyTest()
I have two ASP.NET AJAX UpdatePanels . there are two timers with diffrent intervals. is it possible to update two updatepanels simultaneously together ? like multi thread application . each should be UpdatePanel Update in separate thread in one time. i wrote this code but second timer does not work :
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Welcome to ASP.NET! </h2> <p>
I want to be sure a user only enters alphabetic characters for a field that accepts strings. They should only be able to enter a-z, no numbers. Can the minimum and maximum values be set to a and z, respectively?
I am using RangeValidator whose Minimum and Maximum vales are set in code behind dynamically. Minimum and Maximum values are exracted form the database. These values are in the range of 0 to n (integers only). Therefore user can enter values from0 to n (integers only).Now I have a situation where user can also put -1 which can't be handled by range validator. So my last option is to regular expression to handle such situation.Valid values for the user are (-1, 0-n). But I don't now how to get such regular expression , any help would be appreciated. I can manipulate expression in code behind based on values extracted from the database.Also , maximum possible value for n is 255 (Note: minimum and maximum values are extracted from the database)
I am working on a ASP.NET app that supports user level cultures. Just about everything works, however, I am running into a problem with the RangeValidator. Here is the sample control set:
[Code]....
When a culture that uses "0,0" (pt-BR for example) attempts to load this page with the controls as shown, it bombs (Gives an ASP.NET debug page). If I either set MinimumValue="0" or add CultureInvariantValues="true" the page will load. The problem with this is that on several controls, the minimum value is actually 0.0001. When I use the CultureInvariant setting, that validator is telling me that the following values are invalid: ".031" and "1", no matter what culture I am using to view the page.
I understand the the CultureInvariantValues setting applies only to the values in the Min/Max settings on the validator, not on the data entered in the control that is being validated. But this does not explain why values that should be accepted as valid are being flagged as invalid.Our application currently runs in 20 different countries and is internally translated into 4 languages (based on user culture settings), with 3 more on the board for this year. I have googled this extensively, and while I have found some info on Currency and Date data types, the problems experienced are not the same.
I am trying to put a range validator on a date entered by a user. However, I want the minimum date to by dynamic to only have a user with a DOB which is over 17 yrs ago. Is there a way to put a dynamic value i.e Date.Now() - x;.
The code below when using a traditional ASP.NET DropDownList works perfectly. If a value is not picked (default value still displaying), then the range validator displays the problem. However when I use this same code with an AJAX ComboBox, the RangeValidator returns false every time, and the message is always displayed. Take a look:
[Code]....
So every time I press a button to postback, the "** Item is required**" message is displayed. Again, this works just fine with a regular ASP.NET DDL, just not with the ComboBox from the toolkit. I can get a RequiredFieldValidator working with the ComboBox, but I like the post selection behavior of a RangeValidator better.
I'm having an issue with my ASP.NET RangeValidator controls.
I want to allow users to enter a discount amount, and this amount must be negative (< $0.00). I want to verify that the amount entered in a textbox is a negative value, so I have this in my page markup:
<asp:TextBox ID="tbxDiscount" runat="server" /> <asp:RangeValidator ID="rvDiscount" runat="server" ControlToValidate="tbxDiscount" MinimumValue="0.0" MaximumValue="0.0" EnableClientScript="true" ErrorMessage="Please enter a negative value for a discount" />
and I attempt to set the MinimumValue dynamically in my code before the page gets rendered - to the negative equivalent of my item price. So if the item is $69, I want to set the minimum value to - $69:
I'm developing a web application which get number with decimals. When I write 0.08 the rangevalidator understand 80 and it doesn't valid it. It does well if I write 0,08.The most extrange is In the develpoing computer and in the client computer I have the point as decimal separator in regional settings.Where can I change the decimal separator por rangevalidator in the cliente computer?
i am doin my final year project and in my project i want to watermark multiple images simultaneously where image,logo,position,alpha and key value is stored in a database table ....i need to retreive these details from db table and perform watermark on those images....
I am using HTTP load testing tool to stress test my asp.net 2.0 application. I faced problem that, when I have 1 user access to the system (currently only test on login.aspx), it is very fast ~ 1-2 secs. However, when I run with 10 virtual users at the same time, it takes 10-12 secs for each.
User Response Time (s)
1 10.12 2 10.22 3 11.00 ... 10 12.78
My question is, why ALL of them also takes 10-12 secs? Is it normal? I was thinking that should be some users take 2-3 secs and some 5-6 secs and etc.
both site1 an site2 are using form authentication and creating the token further adding in cookie as below,
FormsAuthentication.Initialize(); FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,username,DateTime.Now, DateTime.Now.AddMinutes(20),rememberMeSet,globalID ,FormsAuthentication.FormsCookiePath);
// Encrypt the ticket. String hash = FormsAuthentication.Encrypt(ticket); //Create the authentication cookie HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash);
My problem is when I'm logging in to Both site1 and site2 then these two are not running simultaneously on single browser using different tab for same user name.one is being logged out when logging to the other application and vice verse.
I have two ajax time for my aspx web page but while the one is ticking , the other stops running. How can i make it both timer run together like the windows form?
I have a text box, a range validator, and a button. The validator is hooked up and prevents the button from doing a post back if the text is out of the range, however I'd also like to enable and disable the button. Is this possible to do within client-side code?
I inherited a site which I am in the middle of updating which has a DropDownList and a RangeValidator assigned to it. The data is bound to the dropdown on Page_Load. The values are retrieved from the database so the value property of each item is set to the unique ID of the item in the DB.
The RangeValidator looks something like:
<asp:rangevalidator id="ddRangeValidator" runat="server" ControlToValidate="ddMenu" ErrorMessage="Please select value in range" MinimumValue="1" MaximumValue="100000" Type="Integer">*</asp:rangevalidator>
I have a method which automatically populates this value in jQuery e.g.
$("#ddMenu").val("An Option");
This works, however, when I try to post the page the range validation fails. Then even if I manually select that value, or select another valid value it still won't validate. The only way to make it validate is to select non-valid value and then re-selecting a valid one.
Here is the data binding code:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load, Me.Load
If Not Page.IsPostBack Then Dim ds As New DataSet() Dim myDbObject As New myDbObject() ds = myDbObject.ToDataSet() // retrieves all objects from the database
<asp:RangeValidator ID="RangeValidator1" runat="server" MaximumValue=" " MinimumValue=" " Type="Double" Text="Value out of range" ErrorMessage="Value out of range" ControlToValidate="WaterLvl" ForeColor="Red"></asp:RangeValidator>
I have a page in which there are multiple updatepanels and each of these update panels are trigerred by different triggers.
These update panels are used to do Async post back and the page is updated with the data retrieved from the async post back.
Now the issue i am facing is that since there are multiple update panels, the update done by one panel is lost when the other panels does the post back.
let me know if any one knows on how to solve this issue.
