Validating Form In Sharepoint?

Sep 23, 2010

I developed a screen in which there are fields like first name,username,password and email. I validated these fields using javascript and came to know that javascript is not that safe. So i decided to validate on server side also. My question is whether i can use asp controls like requiredfieldvalidator, regularexpression validator to validate the form or i have to validate through server side coding??

Sharepoint - Simple Web Form That Writes To A Database... Access Web Form Or Custom .NET?

Feb 21, 2011

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).

Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?

MVC :: Validating Form Values Before Insert?

Sep 21, 2010

Before committing the record from the postback of the Create or Edit method in my controller, I validate the values in the form against some business rules in the GetRuleViloations() of this domain object. The following rule example is written in two ways. The 1st one validates against the numeric values in form, the 2nd one validates using the associated object (lookup table in database) description via the foreign key. I would like to use the 2nd method, but during the Create postback the associated object is always null.

Web Forms :: Validating For Mutually Exclusive Form Elements?

Aug 9, 2010

I need to validate that a user makes a selection from a select list OR they enter text into a textbox. I'm trying to figure out which validator to use. Is there a way to make a CompareValidator do this? Or would I need to write a custom validator? If custom, do I write one for each of the form elements, or does the validation happen upon submit?

Web Forms :: Non-validating Button Will Not Postback Invalid Form?

Nov 10, 2010

(Using ASP.Net 2.0 on Visual Studio 2005, coding in C#)I write in the hope that someone will be able to provide a clue as to how I might best overcome this issue:I've got a form with 2 RequiredFieldValidators, and 2 buttons. Button 1 has 'CausesValidation' set to 'False', and populates some of the other fields on the form from the database (via a postback).Button 2 fires the validation, then if the form is valid brings a javascript popup confirmation box and then, if true, it puts the data in the form into an email.All this is working fine. However......My problem is this: If I press button 2 with my required field(s) empty, the form quite correctly refuses to submit, and highlights the appropriate field(s) with a red *.But: if I then press button 1 (my populating button) it DOES NOT FIRE until I press it a second time!Code snippet follows (markup only - I will of course post code-behind if nec. but I don't think it is)

<script type="text/javascript">
function ConfirmSubmit()

Visual Studio 2010 - .NET Web Form On SharePoint

Oct 13, 2010

I would like to create and deploy an ASP.NET web form on SharePoint server which can create document in SharePoint list (or library). Since I'm not experienced in both these technologies so would appreciate if someone guides me to the right tool. Should I use Visual Studio or SharePoint designer ? Also, I was reading an article on MSDN about "Deploying ASP.NET Web Applications in the Windows SharePoint Services 3.0 _layouts Folder". Is it the best practise or should I go with webpart/solution based deployment?

Unable To Call The SharePoint Custom Web Service From Another SharePoint Farm

Jan 12, 2011

I have deployed a custom SharePoint Web service on Farm A. I am trying to access this Web service from a SharePoint timer job on Farm B. On Farm B, I am creating Class Library project, packaging it (wsp) and then deploying to GAC. The problem is I'm unable to access the Web Service using the following code. TodaysNewSVC is a service reference

TodaysNewSVC.GetTodaysnewsfromInsite objGetNews = new TodaysNewSVC.GetTodaysnewsfromInsite();
objGetNews.PreAuthenticate = true;
objGetNews.Credentials = CredentialCache.DefaultCredentials;
objGetNews.Url = "http://insite-dev.portal/_vti_bin/todaysnews.asmx";
DataTable dt2 = objGetNews.getNewsFromInsite(true, true);

//getNewsFromInsite is a WebMethod which returns the DataTable.

Note: Both farms use the same active directory authentication. I have also done the debugging for Timer Job and feature activation and they are working fine. The problem occurs during the call i.e. getNewsFromInsite
The asmx and wsdl files are accessible from Internet Explorer and also from Windows Console application. Here is the code which I use from console application:

GetTodaysnewsfromInsiteSoapClient objWSClient = new GetTodaysnewsfromInsiteSoapClient();
objWSClient.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;[code]...

Here is the error message:The request failed with the error message:
<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="%2fPages%2fproblem-with-page.aspx%3fc%3d500">here</a>.</h2>

Sharepoint2010 - Sharepoint + Website - Encountering "A Page Can Have Only One Server - Side Form Tag" Error

Apr 21, 2010

I have an ASP.NET Web Site hosted in the _layouts folder of a SP2010 site. One of the pages contains a server-side form and works fine until I try to set its master page to a Sharepoint master page (specifically a modified v4.master) to achieve a consistent look & feel. I've placed my original page content within <asp:content> tags but it now throws an "A page can have only one server-side Form tag" error. I know that ASP.NET pages can only contain a single server-side form but what walkarounds can I use to stop Sharepoint from throwing this error?

MVC :: 2 Validating Linq 2 SQL?

Jun 8, 2010

I'm following along with Nerddinner making a few changes, and can't figure out why my Create form is not validating. I'm using Linq to SQL and trying to use Modelbinding to map my form data automatically. Using the code below, I do not receive any validation errors on the page, but can't make it past my try{} block. When unhandled, the error I receive tells me I'm unable to insert a Null value for "basetype". This is correct based on Database constraints, but why am I receiving exceptions, and not the nice red error messages and validation?

C# - Validating A Value For A DataColumn?

Apr 13, 2010

I'm using a DataGrid with edit functionalities in my project. It's handy, compared to having to edit its source data manually, but sadly, that means that I'll have to deal with validating user input a bit more.

And my problem is basically just that. When I set my DataGrid to EDIT mode, modify the values and then set it to UPDATE, what is the best way to check if a value that I've entered is, in fact, compatible with the corresponding column's data type?

i.e. (simple example)

// assuming
DataTable dt = new DataTable();
DataGrid dg = new DataGrid();

MVC 3 Not Validating My Floats Correctly?

Jan 13, 2011

I've got a View where I allow input, the fields are set as float in my SQL Server 2008 R2 database and I am using Entity Framwork 4. In the Entity Framework Model the field looks like this private Nullable<global::System.Double> _TestNumber;

And the View uses an EditorField to allow input like this:

<div class="editor-field">
@Html.EditorFor(model => model.TestNumber)
@Html.ValidationMessageFor(model => model.TestNumber)

I am however getting this error in the Validation Message: The value '13.51' is not valid for TestNumber. I've tried with a comma instead of period, same thing.

MVC :: Validating Primary Key Which Is Identity?

Sep 14, 2010

I am following this tutorial : [URL]

I am where you "Create" an entry in the table, i have deleted the Id field, as Id is my primary key, and Is Identity = Yes, Identity Increment = 1, Identity Seed = 1.

When i hit the create button, the Id value is being validated, giving an invalid error. If i add the Id column back to the page, and fill in any number and click create, the entry is added to the database, with the Id value incremented (the typed in value does not matter). I believe this must have to do with the Movies.Designer.cs... but not sure how to fix it. Id should not be validated as it auto-incraments, but the model is looking for a Id value..
