Selenium - wait until element is present, visible and interactable even on a scrollable modal in C#

Same question was asked for python here: Selenium - wait until element is present, visible and interactable. However the answers are not covering all the scenarios.
My implementation fails from time to time, when I am not in debug mode.
I consider that waiting for an ID is such a trivial task that should have a straight forward KISS implementation and should never fail.
public IWebElement WaitForId(string inputId, bool waitToInteract = false, int index = 0)
{
IWebElement uiElement = null;
while (uiElement == null)
{
var items = WebDriver.FindElements(By.Id(inputId));
var iteration = 0;
while (items == null || items.Count < (index + 1) ||
(waitToInteract && (!items[index].Enabled || !items[index].Displayed)))
{
Thread.Sleep(500);
items = WebDriver.FindElements(By.Id(inputId));
if (items.Count == 0 && iteration == 10)
{
// "still waiting...: " + inputId
}
if (iteration == 50)
{
// "WaitForId not found: " + inputId
Debugger.Break(); // if tried too many times, maybe you want to investigate way
}
iteration++;
}
uiElement = WebDriver.FindElement(By.Id(inputId));
}
return uiElement;
}

public IWebElement GetActiveElement(string id, int allowedTimeout = 20, int retryInterval = 250)
{
var wait = new DefaultWait<IWebDriver>(_driver)
{
Timeout = TimeSpan.FromSeconds(allowedTimeout),
PollingInterval = TimeSpan.FromMilliseconds(retryInterval)
};
return wait.Until(d =>
{
var element = d.FindElement(By.Id(id));
return element.Displayed || element.Enabled ? element : throw new NoSuchElementException();
});
// Usage would be something like this
GetActiveElement("foo").SendKeys("Bar");
You should be able to create extension method and call the extension instead
public static class WebDriverExtension
{
public static IWebElement GetActiveElement(this IWebDriver driver, string id, int allowedTimeout = 20, int retryInterval = 250)
{
var wait = new DefaultWait<IWebDriver>(driver)
{
Timeout = TimeSpan.FromSeconds(allowedTimeout),
PollingInterval = TimeSpan.FromMilliseconds(retryInterval)
};
return wait.Until(d =>
{
var element = d.FindElement(By.Id(id));
return element.Displayed || element.Enabled ? element : throw new NoSuchElementException();
});
}
}
// usage
_driver.GetActiveElement("foo").SendKeys("bar");

how to order result by displaying each job type by order

I have a search query which search for all jobs in the database and than displays them in accordance to the most recent ones filtering the data by date as follows:
result = db.AllJobModel.Where(a => a.JobTitle.Contains(searchTitle) && a.locationName.Contains(searchLocation)).ToList());
result = (from app in result orderby DateTime.ParseExact(app.PostedDate, "dd/MM/yyyy", null) descending select app).ToList();
result = GetAllJobModelsOrder(result);
after that I have a method GetAllJobModelsOrder which displays jobs in order which seems to be work fine but in my case its not ordering jobs so I need to understand where I am wrong:
private List<AllJobModel> GetAllJobModelsOrder(List<AllJobModel> result)
{
var list = result.OrderBy(m => m.JobImage.Contains("job1") ? 1 :
m.JobImage.Contains("job2") ? 2 :
m.JobImage.Contains("job3") ? 3 :
m.JobImage.Contains("job4") ? 4 :
m.JobImage.Contains("job5") ? 5 :
6)
.ToList();
return list;
}
The result I get is about 10 jobs from job1 and than followed by other jobs in the same order what I would like to achieve is to filter the most recent jobs than display one job from each type of a job.
An example of the input would be as follows:
AllJobModel allJobModel = new AllJobModel
{
JobDescription = "Description",
JobImage = "Job1",
JobTitle = "title",
locationName = "UK",
datePosted = "15/06/2020",
}
The output that I get is as follows:
In where result should be mixed from different jobs.
Excepted resulta as follows a specific order of job source--1. TotalJob[0] :: 2. MonsterJob[0] :: 3. Redd[0] :: 4. TotalJob[ 1 ] :: 5. MonsterJob[ 1 ] ::6. Redd[ 1 ]:
I have tried the following solution but list data structure seems to be not stroing data in order:
private List<AllJobModel> GetAllJobModelsOrder(List<AllJobModel> result)
{
string lastItem = "";
List<AllJobModel> list = new List<AllJobModel>();
int pos = -1;
while(result.Count != 0)
{
for(int i = 0; i < result.Count; i++)
{
if(result[i].JobImage.Contains("reed") && (lastItem == "" || lastItem == "total" || lastItem == "monster"))
{
pos++;
list.Insert(pos,result[i]);
lastItem = "reed";
result.Remove(result[i]);
break;
}else if (result[i].JobImage.Contains("total") && (lastItem == "reed" || lastItem == "monster" || lastItem == "" ))
{
pos++;
list.Insert(pos, result[i]);
lastItem = "total";
result.Remove(result[i]);
break;
}else if(result[i].JobImage.Contains("monster.png") && (lastItem =="total" || lastItem == "reed" || lastItem == "" ))
{
pos++;
list.Insert(pos, result[i]);
lastItem = "monster";
result.Remove(result[i]);
break;
}else if(result[i].JobImage.Contains("reed") &&( lastItem == "reed"))
{
if(result.FirstOrDefault(a=>a.JobImage.Contains("total") || a.JobImage.Contains("monster")) != null)
{
lastItem = "total";
break;
}
else
{
pos++;
list.Insert(pos, result[i]);
lastItem = "reed";
result.Remove(result[i]);
break;
}
}
else if (result[i].JobImage.Contains("total") && (lastItem == "total"))
{
if (result.FirstOrDefault(a => a.JobImage.Contains("reed") || a.JobImage.Contains("monster")) != null)
{
lastItem = "monster";
break;
}
else
{
pos++;
list.Insert(pos, result[i]);
lastItem = "total";
result.Remove(result[i]);
break;
}
}
else if (result[i].JobImage.Contains("monster") && (lastItem == "monster"))
{
if (result.FirstOrDefault(a => a.JobImage.Contains("total") || a.JobImage.Contains("reed")) != null)
{
lastItem = "reed";
break;
}
else
{
pos++;
list.Insert(pos, result[i]);
lastItem = "monster";
result.Remove(result[i]);
break;
}
}
}
}
return list;
}
also what I found is that the value of the elements in the list is different from what its actual value. So I am not sure if this is an error with my code or with visual studio:

you can use the below concept here. I am sorting a list based on the numeric value at the end of each string value using Regex.
List<string> ls = new List<string>() { "job2", "job1", "job4", "job3" };
ls = ls.OrderBy(x => Regex.Match(x, #"\d+$").Value).ToList();

Certainly the requirement was not as straight forward as initially thought. Which is why I am offering a second solution.
Having order by and rotate the offering "Firm" in a type of priority list for a set number of times and then just display whatever comes after that requires a custom solution. If the one algorithm you have works and you are happy then great. Otherwise, I have come up with this algorithm.
private static List<AllJobModel> ProcessJobs(List<AllJobModel> l)
{
var noPriorityFirst = 2;
var orderedList = new List<AllJobModel>();
var priorityImage = new string[] { "TotalJob", "MonsterJob", "Redd" };
var gl = l.OrderBy(o => o.datePosted).GroupBy(g => g.datePosted).ToList();
foreach (var g in gl)
{
var key = g.Key;
for (int i = 0; i < noPriorityFirst; i++)
{
foreach (var j in priorityImage)
{
var a = l.Where(w => w.datePosted.Equals(key) && w.JobImage.Equals(j)).FirstOrDefault();
if (a != null)
{
orderedList.Add(a);
var ra = l.Remove(a);
}
}
}
foreach (var j in l.ToList())
{
var a = l.Where(w => w.datePosted.Equals(key)).FirstOrDefault();
if (a != null)
{
orderedList.Add(a);
var ra = l.Remove(a);
}
}
}
return orderedList;
}
To test this process I have created this Console app:
static void Main(string[] args)
{
Console.WriteLine("Start");
var l = CreateTestList();
var lJobs = ProcessJobs(l);
lJobs.ForEach(x => Console.WriteLine($"{x.datePosted} : {x.JobImage}"));
}
private static List<AllJobModel> CreateTestList()
{
var orderedList = new List<AllJobModel>();
var l = new List<AllJobModel>();
var priorityImage = new string[] { "TotalJob", "MonsterJob", "Redd" };
var rand = new Random();
var startTime = DateTime.Now;
for (int i = 0; i < 20; i++)
{
var j = rand.Next(0, priorityImage.Length);
var h = rand.Next(0, 4);
var a = new AllJobModel();
a.JobDescription = "Desc " + i;
a.JobImage = priorityImage[j];
a.JobTitle = "Title" + i;
a.locationName = "UK";
a.datePosted = startTime.AddDays(h);
l.Add(a);
}
for (int i = 0; i < 20; i++)
{
var j = rand.Next(0, priorityImage.Length);
var h = rand.Next(0, 4);
var a = new AllJobModel();
a.JobDescription = "Desc " + i;
a.JobImage = "Job " + i;
a.JobTitle = "Title" + i;
a.locationName = "UK";
a.datePosted = startTime.AddDays(h);
l.Add(a);
}
return l;
}

TaskCompletionSource and dismiss causes that multiple custom alertdialogs aren't appearing

I got a problem related with the TaskCompletionSource object and the Dismiss function of an alert. This problem does not appear within the IOS version of the application
When the application sends an notification, two alerts with working functionality will show up when the user activates the application:
Authentication
Filling in a value.
However, when I enter the application I only get to see the authentication(because this alert is called first within the app) and the second alert never shows up. I already tried to override the Dismiss function and set the TaskCompletionSource object result to null, but this causes the same alert to appear an X times before the application crashes. Is there a way to repeat the TaskCompletionSource object so that I can see all the alerts? Or what kind of modifications do I need to make on the Dismiss function so that the TaskCompletionSource is completed once all the alerts are shown?

This looks like an and/or problem between threading or simply not setting the task completion.
In the IOS version you have
dismiss = async () => {
dismiss = async () => {};
await outer.FadeTo(0, 50);
innerView.RemoveFromSuperview();
tcs.SetResult(null);
};
There is no matching tcs.SetResult(null); statement in the android version.
Also of note is the async invocation, as waiting to call SetResult will block the main thread without it.

Make Code Fast Execute - replace For loops

It takes lot of time to execute these loops due to for loop implementation
How can I replace it to be more fast, the under laying table do not have much records too, plus I have made the primary keys too , but still the for loops are slow

the for loop under second for each need to placed ... need some help

You should factor out of the inner loop everything you can. As the code stands right now, you are unecessarily repeating the following operations:
returnItem.Code.Trim();
returnItem.GrnNo.Trim();
returnItem.WbcNo.Trim();
I have nowhere near enough information to judge if this will have any performance impact.
Other suspects are new SalesOrderModule.Entity.Transactions.POCDANumberTracking() and returns.Add(temp). If returns is somekind of ordered list, then this could have a considerable performance hit. If its a simple List then it shouldn't and there isn't much you could do to improve it anyways.
Concerning the constructor, only you know how expensive it is but there is not much you can do to avoid it either.
All that said, your code would look something like this:
Entity.Transactions.POCDANumberTracking temp;
foreach (Entity.Transactions.POCDANumberTracking returnItem in returnRejectList)

I have to limit the entries coming under the foreach loops, that is best way by debugging the code
so the data layer codes referring in the
sampleTable.Reads(false);
sampleTable2.Reads(false);
sampleTable3.Reads(false);
sampleTable4.Reads(false);
need to modified by including the Item for search (I mean the SQL STATEMENTS)

Multiple Task.Run not waiting/running properly

I'm trying to optimize a heavy process with some tasks, but it seems that after the first iteration it skips the ProcessQueue method run.
private void ImportSheet(Excel.Worksheet Data)
{
this._ImportedSlurry = new ConcurrentQueue<AnalizedDataDTO>();
this._LastRowReached = false;
this._CurrentRow = this._FirstRow;
while(!this._LastRowReached)
{
AnalizedDataDTO ImportedRow = this.ValidateRow(Data, _CurrentRow);
Task task1 = Task.Run(() => ProcessQueue(Enumerable.Range(this._CurrentRow, 50).ToArray(),Data));
Task task2 = Task.Run(() => ProcessQueue(Enumerable.Range(this._CurrentRow+50, 50).ToArray(),Data));
Task.WaitAll(task1, task2);
this._CurrentRow += 100;
}
}
private void ProcessQueue(int[] range, Excel.Worksheet Data)
{
for (int i = range.First(); i < range.Length; i++)
{
AnalizedDataDTO ImportedRow = this.ValidateRow(Data, i);
if (ImportedRow == null)
{
this._LastRowReached = true;
break;
}
else
{
this._ImportedSlurry.Enqueue(ImportedRow);
}
}
}

The problem is your for-loop, to be specific its if-condition.
You should either iterate over range, i.e.
foreach (var i in range)
or iterate over an index, i.e.
foreach (var idx = 0; idx < range.Length; idx++)
{
var i = range[idx];
For example assume that this._CurrentRow == 100, then your version of the for loop would look like:
for (int i = 100 /* range.First() */; i < 50 /* range.Length */; i++)
