AJAX :: RangeValidator With CultureInvariantValues=True?
Jan 12, 2010
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.
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 thought my issue was related to the Validators not working in UpdatePanels but that does not seem to be the case.
All validators fire when they should but, the error warning message clears when the updatepanel updates.
for example...
textbox1 range 1 to 23. dropdown1 updates the updatepanel. enter 99 error shows, but will disapear when I change value of dropdown1. textbox1 value still 99 so validator message should still show but it does not.
It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.
When I do a TextChanged event on slider1 (by dragging the slider, changing the value), the protected void Slider1_TextChanged(object sender, EventArgs e) event FIRES, however, the TWO other sliders, protected void Slider2_TextChange, and protected void Slider3_TextChange also FIRES. What gives? why do they fire when I am physically only sliding the slider1 across. The two other sliders values did not change on the webform, yet the event fired.
In order for the event to fire for slider1, I had to insert "Autopostback=true" in the <asp:TextBox ID="Slider1" autopostback="true" OnTextChanged="Slider1_TextChanged">. For <asp:TextBox2> and <asp:Textbox3> I did not put the autopostback event for now.
I have a about 10 modalpopupextenders on one page.The problem is that when I set the property "DropShadow=true", it causes my modal popup panel to move up the screen(IE) and only the bottom 25% of the panel shows.
I am using a CollapsiblePanelExtender inside a ListView and aside from one minor, but annoying problem, it works fine. The problem is, when the page first renders, I see all the panels expanded for a short moment before they all get collapsed. There are multiple CPEs because the ListView is databound to about 45 records. I have the Collapsed=True, and based on some not-quite-clear documentation, I also set the CollapsedSize=0 and the panel's Height=0. After that last change (panel height), they are now displaying collapsed except that the gridviews inside the target panel is still showing in a sort of overlapped way. I'd upload a picture so you can see, but I don't think I can in this forum. Since the page looks like this for about a half-second, it's enough to confuse and annoy my users (and myself). Can someone please help me set this up to truly show collapsed when the page loads?
I did also try looking at the code in the AJAX Toolkit's sample website but I still don't quite understand "Collapsed - Specifies that the object should initially be collapsed or expanded. Set this to match your initial size. In this case, we initially set the panel to a height of 0 to match the CollapsedSize property, so when the page first renders, we don't see the panel expanded." If the options are True/False, why does it say to set this to match your initial size? And I did set the panel height to 0 to match the collapsedsize and it's just not working.
I have an imagebutton in Gridview control which is placed in ajaxtoolkit:TabPanel. Clicking on the imagebutton for the first time works fine. It posts back and does the desired action. However, when IsPostBack is true, it doesn't work. Even the onclick event is not called although the page posts back. Please help. Given below is the code for the same:
I'm attempting to set the visibility my UpdatePanel to true upon a button click event (as shown below). It should be rather straightforward but unfortunately it's not working at all. Any idea why it's going wrong?
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 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 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 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;.
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 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>
