Is it possible to access a control's attributes within a custom validation method? Lets say I'm validating a textbox called txtName. Is it possible to access the ID of it or anything? args seems to only give me access to the value.
View 2 RepliesI have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.
View 2 RepliesI was just wondering, let's say I created a Method that is in a partial class in App_Code, and this Method would replace the same type of Method that would otherwise be in many files, and so, since it would be called from many files and would probably be called and used very frequently especially because of this. Would this overload this class? I'm not saying what would most likely happen, I'm just asking if it would be even remotely possible?
View 2 RepliesI have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?
I have an issue in my application . When I am calling a Javascript function OnClick of Submit button, the range validators on my page doesnt work.
View 2 Repliesi have a web service that i use for the AutoCompleteExtender, let the below code show you what i'm trying to do: [Code]....
this method is called, and when it calls the method inside the Patients Class, it gets lost. does that mean that i can't use 3-tier approach with web methods?
here is the problem I have:There are 2 textboxes: uxActiveDate, uxExpireDate. Expiredate has 2 validators attached to it:
In the markup:
[Code]....
In the code behind file:
[Code]....
The problem is when expire date is selected before active date, and current date, then both the error messages are displayed. I have to set priority or something so that these 2 messages are not displayed at the same time. Is it doable?
PS: Since if required field validator does not pass, then other validators dont execute, I guess there is a way to set priority so that if one validation is not passed others will not execute. Validation summery is not an option, since it does not show message client side.
I having a Module UIMessagesMod. In that module, i have used a method with the name DisplayMessages. Please find the code below.
Module UIMessagesMod
Public Function DisplayMessages(ByVal LabelControl As Web.UI.WebControls.Label, Optional ByVal RemoveMessages As Boolean = True) As Int32
Return RowCount
End Function
End Module.
I tried to call DisplayMessages in the master page, but it leaves me an error saying "'DisplayMessages' is not declared. It may be inaccessible due to its protection level."

1) here I want to call 2nd Execute method inside 1st Execute method.
2) Also, I want to create "abstract class" inside 2nd Execute method. Is it possible way? If yes then how?
can we use the same validator of a control for two different buttons, or do we need to write add a validator for each control for two different buttons.

I have the following method in a class withing a website.
public static void Authorise(int role, Page callingPage)
{
callingPage.Master.FindControl("divUnauthorised").Visible = true;
callingPage.Master.FindControl("ContentPlaceHolder2").Visible = false;

Now this works fine but I really want to just have the one parameter of role and not require the page to pass itself into the method. Is there a way of finding the object that called the method and casting it to a System.Web.UI.Page?

I have a textbox that I want the user to enter an integer in.1) I have created a required field validator, to ensure it is not left blank.2) A compare validator, to ensure the value entered is an integer using datatypecheck.3) A range validator to limit the range of the entered integer.If a letter is entered, instead of an integer, errors from both 2) and 3) are displayed.Is there a way to only show the error from 2) if a letter is entered and 3) if the integer is out of range - rather than both?
View 1 RepliesI have a Web Form that uses Master Pages. I only tell you this part so you understand the layers.
On the page, I have a web user control. I can see public methods on that user control by simply calling userControlName.PublicMethod();
However, there is a button on this page which generates additional content. This content is based on a placeholder control and adding additional web user controls :
[Code]....
Now, on the main form, I want a submit button that will call a public method of each "subForm" that was added at runtime.
I have tried various forms of Control C = This.Page.Master.FindControl("cpBody").Findcontrol("ctl01")... etc, but can never seen to get the right combination.
Below is a listing of the web form
[Code]....
Does anyone know how I would go about calling a method found in the master page code behind from a user control's code? The user control is on the master page. The method I want to call is public.
I can easily call a method found in the pages code behind using:
Page.GetType().InvokeMember("TheMethodsName", System.Reflection.BindingFlags.InvokeMethod, null, this.Page, null);
or I can call a method found on the master page from my aspx page code behind using:
((MasterPage_MasterPage)Page.Master).TheMethodsName();
But I am stuck because I can't find the MasterPage in my user control code behind.
I have an aspx page which has an usercontrol say UC1 for selecting query paramters.
UserControl uc1 in turn opens another user control (UC2) as a modal popup.
1. On OK click, I am setting the values of another usercontrol (uc1) from the control uc2 by invoking a page method(doAccept). It appears to call the method and values seems to be set. But the problem the usercontrol/page does not display the new value or in otherwords it is not refreshed.
If the above is not possible is there any other way to refresh the parent page.

I have a problem with calling a method on a aspx page from a usercontrol.
The case is: I have 1 main page with 5 usercontrols, when something goes wrong in the code I want to display the error message in a Modalpopup Extender. I can create for each usercontrol a different modalpopup extender but isn't much easier when I make 1 popup in the aspx page. But the problem is: How should I call a method in the aspx page that open the popup?
I have search several hours on the internet but can't find anything useful.

i have a method in my back end that i would like to call from my front end, but can't seem to get it working. here is my code:

<span class="folder">
<asp:label ID="lblPlantName" runat="server" Text='<% GetPlantName(item) %>'></asp:label>

the getplantName method should return a string and fill the text in. But this is not getting called for some reason.
