Using Entity framework how can I pick any string to display in a textbox. Using myReader in the past I would do the following:
while (myReader.Read())
{
string sName = myReader.GetString(1);
txtName.Text = sName;
}
You have to load the entity (=table) you desire and than assign the property of the entity to the textbox.
Something like:
using (var myContext = new EntityContext())
{
myContext.TableName.Load(); //this will load all rows from the table
var list = myContext.TableName.Local; //.Local is a list of the entities which gets populated when you cann the Load() method
//now you can either enumarte your list like so
foreach (TableName item in list)
{
string sName = item.PropertyName; //PropertyName is the property you want to display, this would be like using not an index in myReader.GetString(1) but the columnname myReader.GetString("ColumnName")
txtName.Text = sName;
}
//or if you want to get a certain item out of your list you can use LINQ/MethodChains
//MethodChain
var item = list.First(x => x.PropertyName == "HelloWorld!");
string sName = item.PropertyName;
txtName.Text = sName;
//LINQ
var item = (from x in list
where x.PropertyName == "HelloWorld!"
select x).First();
string sName = item.PropertyName;
txtName.Text = sName;
//the methodchain and linq is a "new" technology that simplifies this code (which does the same)
TableName item = null;
foreach (TableName tempItem in list)
{
if (tempItem.PropertyName == "HelloWorld!")
{
item = tempItem;
break;
}
}
string sName = item.PropertyName;
txtName.Text = sName;
}
I have a WPF Application with two ComboBox
When I select the first one the items related to the first combobox will be populated on the second one
Here is my select Property
public string SelectedApplication
{
set
{
if (_selectedApplication == value) return;
this._selectedApplication = value;
InitializeTransactionTypes();
}
get
{
return this._selectedApplication;
}
}
here i am checking a matching id between the two comboboxes to populate the second combobox items.
ObservableCollection<TransactionTypeViewModel> _transTypeObsList = new ObservableCollection<TransactionTypeViewModel>();
private void InitializeTransactionTypes()
{
if (_selectedApplication != null)
{
var getAppCode =
ApplicationVModel.GetAllApplications()
.FirstOrDefault(apps => apps.Name == _selectedApplication);
var transTypeList = TransactionTypeVModel.GetAllViewModelTransTypes()
.Where(t => getAppCode != null && t.Id == getAppCode.Id);
transactionTypes = new ObservableCollection<TransactionTypeViewModel>(transTypeList);
NotifyPropertyChanged("TransactionTypes");
}
}
More information about methods:
List of VM mapped from List of Model
public List<TransactionTypeViewModel> GetAllViewModelTransTypes()
{
TransactionTypeViewModels = TransactionTypeModel.GetAllTransactionTypes().Select(transType => new TransactionTypeViewModel
{
Id = transType.Id,
Name = transType.Name,
})
.ToList();
return TransactionTypeViewModels;
}
Lets say I select first combobox has {A,B,C,D} ...and the second combobox has {A'1,A'2,A'3}, when I select item from first Combobox the second combobo keeps populating
items. I wanted to show only {A'1 for A} {B'1 for B} ...etc but now what it does is {A'1 A'1 A'1 ..... for A} {B'1 B'1 B'1 ....for B} for every select.
I want the previous selection to be cleared and display a new list per select. Thanks
To sum up comments. Instead of creating new ObservableCollection every time something changes reuse one that you already have and it will notify UI about changes. Your InitializeTransactionTypes should look something like this:
private void InitializeTransactionTypes()
{
if (_selectedApplication != null)
{
var getAppCode =
ApplicationVModel.GetAllApplications()
.FirstOrDefault(apps => apps.Name == _selectedApplication);
transactionTypes.Clear();
foreach(var transactionItem in TransactionTypeVModel.GetAllViewModelTransTypes().Where(t => getAppCode != null && t.Id == getAppCode.Id))
transactionTypes.Add(transactionItem);
}
}
and like this you should not have to notify about TransactionTypes changes any more
I have a VF page form that has a text field. The value of this text field is compared to an existing opportunity custom field. If the value of this text field exists in an opportunity, I go ahead and create a new record.
Everything works out fine except when I create a Apex Test Class.
I need to create an opportunity and hard code the value for the custom field. Unfortuneatly, this field is not writeable.
Has anyone ran into this issue before?
This is the error that I'm getting:
Error: Compile Error: Field is not writeable: Opportunity.Deal_Registration_ID__c at line 9 column 103
Below is my Apex Class.
My test class is at the very bottom.
Any help is greatly appreciated.
Cheers!

system.assertEquals(v.Deal_Registration__c, opp.Deal_Registration_Id__c);
}
}
}
What's the Opportunity.Deal_Registration_ID__c field type? If it's a formula field or autonumber it will really really be not writeable from Apex.
Generally speaking in such scenarios you'd have to insert the Opportunity (without this field set), then read it back from database after a successful insert. If it's autonumber - magic will happen on it's own (although I wouldn't say it's a best idea to have some kind of license numbers consecutive & easy to fake ;)), if it's a formula field - make sure you've set all fields that are used in calculation prior to the insert.
So something like this should do the trick:
Opportunity opp = new Opportunity(Name='test opp', StageName='stage', Probability = 95, CloseDate=system.today());
insert opp;
opp = [SELECT Id, Name, Deal_Registration_ID__c FROM Opportunity WHERE Id = :opp.Id];
// Optionally - make sure value was set
System.assertNotEquals(null, opp.Deal_Registration_ID__c);
System.assert(opp.Deal_Registration_ID__c.length() > 0); // if it's a String
Vault__c vault = new Vault__c(
Deal_Registration__c = opp.Deal_Registration_ID__c ,
Scenario__c = 'BIG-IP front ending Firewalls',
isValidDealReg__c = true,
Status__c = 'Application Received',
Load_Balancer_is_a_Firewall__c = 'Yes',

Providing_DDos_protection_except_ASM__c = 'Yes',
No_Traffic_Traverse__c = 'Yes',

I can't actually see where you're trying to write to the field — or did you remove it because it wasn't working?
That aside, the answer is that you can not write to a roll-up summary field. If you require a value in that field you should insert child records to your parent test records, with appropriate field values such that your summary field calculates a value.
Also, I can see that you're querying PerferredIA__c at the start, your test methods should never depend on data being in the system already, you should insert your records yourself in your test code. The reason for this is that if you try to deploy to an org which has no relevant data, your tests will fail and so, subsequently, will your deployment.
For situations like these, consider mock objects (or just variables simulating expected values), similar to inserting test values as Lacey suggests. This technique is required to achieve 100% coverage when doing callouts, for example, since they terminate tests at the moment of the call.
How do I update a list of different Telephone, IPPhone using this
static void Main(string[] args)
{
Console.Write("Enter userid : "); // I would pass this in from the first
//Field in the .csv file 2439009
String username = Console.ReadLine();
try
{
DirectoryEntry myLdapConnection = createDirectoryEntry();
DirectorySearcher search = new DirectorySearcher(myLdapConnection);
search.Filter = "(cn=" + uid + ")";
search.PropertiesToLoad.Add("Telephone","IPPhone");
SearchResult result = search.FindOne();
if (result != null)
{
// create new object from search result
DirectoryEntry entryToUpdate = result.GetDirectoryEntry();
// show existing title
Console.WriteLine("Current title : " + entryToUpdate.Properties["Telephone][0].ToString());
Console.Write("\n\nEnter new title : ");
// get new title and write to AD
String newTitle = Console.ReadLine();
entryToUpdate.Properties["Telephone"].Value = newTelePhone;
entryToUpdate.Properties["IPPhone"].Value = newIPPhone;
entryToUpdate.CommitChanges();
Console.WriteLine("\n\n...new title saved");
}
else Console.WriteLine("User not found!");
}
catch (Exception e)
{
Console.WriteLine("Exception caught:\n\n" + e.ToString());
}
}
static DirectoryEntry createDirectoryEntry()
{
// create and return new LDAP connection with desired settings
DirectoryEntry ldapConnection = new DirectoryEntry("mydomain.dm.com");
ldapConnection.Path = "LDAP://OU=myusers,DC=sales,DC=US,DC=US";
ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
return ldapConnection;
}
I'm guessing you've grabbed someone else's code and don't know how to use it?
You should understand that this code can (will?) cause serious server problems as the DirectoryEntry resources are not closed correctly.
Every DirectoryEntry variable in your Main method should be wrapped in a using(){} statement.
Try something like this:
You define a class CSVRecord which holds your data from the CSV - read that in using FileHelpers. The class looks like this:
public class CSVRecord
{
public string EmployeeNumber { get; set; }
public string TelephoneNumber { get; set; }
public string IPPhoneNumber { get; set; }
}
Once you've read that class in, you need to iterate over its elements, and do the update for each of them.
CSVRecord[] listOfEmployees = (read in via FileHelpers)
// define root for searching your user accounts
using (DirectoryEntry root = new DirectoryEntry("LDAP://dc=yourcompany,dc=com"))
{
// set up directory searcher to find users by employeeId
using (DirectorySearcher searcher = new DirectorySearcher(root))
{
searcher.SearchScope = SearchScope.Subtree;
// iterate over all entries in your list of employees
foreach (CSVRecord csvEntry in listOfEmployees)
{
searcher.Filter = string.Format("(&(objectCategory=user)(employeeId={0}))", csvEntry.EmployeeNumber);
// search for that employee
SearchResult result = searcher.FindOne();
// if found - access the DirectoryEntry
if (result != null)
{
DirectoryEntry foundUser = result.GetDirectoryEntry();
// update properties from values in CSV
foundUser.Properties["telephoneNumber"].Value = csvEntry.TelephoneNumber;
foundUser.Properties["ipPhone"].Value = csvEntry.IPPhoneNumber;
// save changes back to directory
foundUser.CommitChanges();
}
}
}
}
Does that work for you??
