C# - How To Validate Against Multiple Validation Groups

Mar 14, 2011

I have a Form like this.

UserID has to be validated when user clicks "Check Availability" and "Submit"

Hence "UserID" required field validator has to be assigned two grops.

As if now it is assigned only Group1

[code]....

I have already gone through How to validate against Multiple validation groups?

which talks about validating Group1 and Group2 when user clicks "Submit" which is a good alternate solution.

How To Validate Against Multiple Validation Groups

Mar 24, 2010

I have two validation groups: parent and child

I have an add button that needs to only validate the child validation group which is easily done. The save button needs to validate against the parent and child validation groups, both client side and server side. I think I know how to do it server side by calling the Page.Validate("groupname") method for each group, but how can it be done client side?

Web Forms :: To Validate Multiple validation Groups With The Click Of One Button?

Apr 1, 2010

I need to be able to validate multiple validation groups with the click of one button. My Form consists of two text boxes and a drop down list for input. The form also, currently, has three buttons, one for each control. Each of those buttons are tied to a validation control and if the validation is successful, it will add the user inputted data into a database that I have. The interesting part comes when I need to add a forth button which will act as a "Save All" Button. When this button is clicked, I need it to fire the three validation groups.

Is it possible to add multiple validation groups to the "Save All" Button?

Data Controls :: Validate Multiple Validation Groups In GridView

May 7, 2015

I have a Dynamic GridView on a page as below. The user can add or delete rows. When inserting record, the code is executed one row at a time. I have 3 rows to be inserted to the database. Here is the issue:

-if the first row is not completed, then no record is added to the database

-if the first row is completed and the second row is not, then only the first row is inserted in the database

-if the first row is completed, the second row is not complete, and the third row is completed, then only the first row is inserted in the database.

below is the code:

protected void GridView1_AddNewRecord(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["DatabaseVestConnectionString1"].ConnectionString;
SqlConnection con = new SqlConnection(constr);
SqlCommand cmd;
string query1 = "INSERT INTO kart_Bestilling(SakBehandlingCode, KystverketRegionID, KystverketAvdelingID, BestillerReferanse, BestillerLeveringAdresse, BestillerPostKodeBy, BestillerNavn, BestillerStilling, BestillerEpost, BestillerTelefon, BestillingBeskrivelse, BestillingDato, BehandlingSakNummer, BehandlingBeskrivelse, BehandlingStatus)" +

[code]...

How to arrange this piece of code to validate all rows before any insert? or avoid inserting a row if there is one row not complete?the conditions starts with int rowIndex = 0;

if (txtBestillerReferanse.Text != "" && txtBestillerEpost.Text != "" && txtBestillerNavn.Text != "" && txtBestillerPostKodeBy.Text != "" && ddKartTypeName.SelectedValue != "Velg KartType" && ddKartNummerName.SelectedValue != "Velg KartNummer" && tBestillingAntallKart1.Text != "")

Validation Rule Belong To Multiple Groups?

Feb 18, 2010

Is it possible for an ASP.NET Validation Rule to belong to multiple groups? I'd like to validate the same control in different ways based on what mode the form is in using a single Validator. For the purposes of this question, the modes are Simple, which requires fewer fields, or Complex, which requires more fields. I know I can write CustomValidators (which I have done in the past), but I'd like a simpler solution.

So, I'd like to combine the following:

<asp:RequiredFieldValidator ValidationGroup="Simple" ControlToValidate="Name" />
<asp:RequiredFieldValidator ValidationGroup="Complex" ControlToValidate="Name" />

MVC :: 2 - Dynamic View Content - Render A Page That Will Have Multiple Radio Button Groups As Well As Multiple CheckBoxes

Aug 4, 2010

I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.

table structure:
PackageID uniqueidentifier
PackageName string
ItemName string
RadioGroupName string
ViewControlName string

This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as

1 / "First Package" / "Item1" / "First Group" / "RadioButton"
2 / "First Package" / "Item2" / "First Group" / "RadioButton"
3 / "First Package" / "Item3" / "First Group" / "RadioButton"
4 / "First Package" / "Item4" / null / "CheckBox"
5 / "First Package" / "Item5" / null / "CheckBox"
6 / "First Package" / "Item6" / "Second Group" / "RadioButton"
7 / "First Package" / "Item7" / "Second Group" / "RadioButton"
8 / "First Package" / "Item8" / "Second Group" / "RadioButton"

Given this result set, I need to render the view as follows:

A RadioButton group with 3 options (Item1, Item2, Item3)
A CheckBox (Item4)
A CheckBox (Item5)
A RadioButton group with 3 options (Item6, Item7, Item8)

I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:

Web Forms :: Iterate Through Validation Groups?

Mar 31, 2010

I have a multi section form which the user can jump between sections to complete. Each section has its own validation group associated with it. I want to create a summary page which itterates through each of the validation groups and outputs if it is valid or not by changing an associated text.The problem that I am having is that once one validation group fails validation all subsequent sections also report as failing - presumably as the page.isvalid is still holding the fact that a previous group has failed

Web Forms :: How To Assing 2 Validation Groups To A Button

Feb 6, 2010

I thought I could assign more than 2 validation groups, separated by comma as follows.

<asp:Button ID="Button2" runat="server" Text="both v1 & v2 validate" ValidationGroup="v1, v2" onclick="Button2_Click"/>

but it didn't work.What i want to do is, when a user clicks button1, it only validates validation group"v1" When button2 is clicked, it validates both "v1" & "v2" validatino groups.
<asp:TextBox ID="TextBox1" runat="server" ValidationGroup="v1"/>
<asp:RequiredFieldValidator
ID="RequiredFieldValidator1" runat="server" ErrorMessage="*" ValidationGroup="v1" ControlToValidate="TextBox1"/> [code]....

Security :: Web.config Authorization Roles With Local Groups With Domain Groups In Them

Sep 29, 2010

I am "DomainMyDomainUserName" If I do this:

[Code]....

I can access the website I've created on my local machine in debug mode; and with my domain account as a local administrator, if I do this:

[Code]....

I can still access the website; and with my domain account in a Domain Group named "DomainDomainLocalSecurityGroup", if I do this:

[Code]....

I can still access the website; HOWEVER, if I create a Local Group on my machine named "LocalMachineGroup" and I add "DomainMyDomainUserName" to this group and I do this:

[Code]....

I get an Access Denied error trying to access the website. What I want to do is, have a group on my local machine (for testing), on a test web server, and on a production web server named "MyWebsiteUserAccess" with the same Domain Group (filled with Domain Users allowed access to the site) in all of these local groups; so that when I test the web application on my local machine, on my test web server and on my production web server, I don't have to change the Web.config file to have it work on each AND if the Domain Group name ever has to change, it won't affect access to the website.

What am I overlooking or is this even possible to do this way? I understand that there is a way to do Role Management through ASP.NET but I don't understand that well enough yet to implement that (and will probably go that route once I've done the research on how to best implement it for purpose of access control of this intranet site).

Enumerating Groups Using WindowsIdentity.GetCurrent() Returns Old Set Of Groups

Feb 1, 2011

I have a user that when I attempt to enumerate her groups using either System.Security.Principal.WindowsIdentity.GetCurrent().Groups on user's computer
or System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups on the IIS server, I get a list of their old groups, not their new. I have checked the DC that they authenticate to and the ASP.NET page is running inside a SharePoint instance so the LogonUserIdentity most like is being provided from there Kerberos ticket.
Should I be looking up the groups directly from the AD instead of relying on the WindowsIdentity or LogonUserIdentity?

C# - Get Local Groups And Not The Primary Groups For A Domain User

Dec 18, 2010

i have a code to get the groups a user belongs to.

try
{
DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName));
DirectoryEntry user = adRoot.Children.Find(completeUserName, "User");
object obGroups = user.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
// Create object for each group.
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
listOfMyWindowsGroups.Add(obGpEntry.Name);
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex);
return false;
}

the above code works fine when i have to find the groups of a local user but

for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups.

Research

I did some finding and got that i am being returned the primary group of the domain user

called "Domain User" group

but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions

another code using LDAP

string domain = Environment.UserDomainName;
DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
DirectorySearcher search = new DirectorySearcher();
search.SearchRoot = DE;
search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name
search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups
try
{
SearchResult result = search.FindOne(); // Grab the records and assign them to result
if (result != null)
{
DirectoryEntry theUser = result.GetDirectoryEntry();
theUser.RefreshCache(new string[] { "tokenGroups" });
foreach (byte[] resultBytes in theUser.Properties["tokenGroups"])
{
System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0);
DirectorySearcher sidSearcher = new DirectorySearcher();
sidSearcher.SearchRoot = DE;
sidSearcher.Filter = "(objectSid=" + mySID.Value + ")";
sidSearcher.PropertiesToLoad.Add("distinguishedName");
SearchResult sidResult = sidSearcher.FindOne();
if (sidResult != null)
{
listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]);
}
}
}
else
{
new GUIUtility().LogMessageToFile("no user found");
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user.
return false;
}

this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...?

How To Validate More Than One Validation Group At A Time

Mar 13, 2010

VWD 2008 Express. Visual Basic.

I have two validationsummary controls on my page for aesthetic reasons. Each control is assigned a validation group (StudentInfo and Grades). validation controls in the upper part of my page are in validationgroup StudentInfo and those in the bottom part of my page are in validationgroup Grades.

However, I only have one "Save" button control that causes validation. I want the Save button to validate both groups of controls, but it appears to only allow one Validation group to be specified in its properties.

Is there a way to have a button cause validation for both groups?

Validate Booleans And Also Client Validation Is Not Working?

May 17, 2010

there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully?

My model goes like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace PitchPortal.Core
{
public class DocumentMetadata
{
//[Required]
// public bool visibility { get; set; }
[Required,StringLength(10, ErrorMessage = "title is too long")]
public string title { get; set; }
[Required, StringLength(10, ErrorMessage = "description is too long")]
public string description { get; set; }
[Required, StringLength(10, ErrorMessage = "summary is too long")]
public string summary { get; set; }

Validation - MVC 3 Validate Dynamic Form Fields?

Mar 10, 2011

I'm working on a very dynamic site build at the moment. What I'm trying to do is creating something like a survey that can be created dynamically from a control panel. In the control panel you add input fields (these are saved in a database), what the user then see is a form that I generate from the database. So if I add 3 input fields to the database the survey will contain 3 fields. If I add 20 fields the survey will have 20 fields.

Now my problem is that I want to validate these fields, and I would like to be able to hook me in with the standard validation flow. I can't create a Model with validation rules since the number of fields and their names are dynamic the only thing I know is what kind of data that is expected in every field (this rule is found in the database). In an ordinary case I would get the automatic highlighted fields that are not valid and so on thanks to the built in validation flow with ValidationResult and so on.

So the question now is can I somehow simulate parts of the validation and then hook me back in with the validation result, and if not valid, the form prints the error messages and fill the fields with the data that was given?
