After refreshing the page, the selected filters is lost

In my web application, when I try to select some values for filtering data, it is going to be selected and saved in backend (C#) successfully, but after refreshing the page, the selected data is lost.
This is the code in Typescript, which being run after save button is clicked.
public async updateAndSaveLayout(isSavedForAllUsers: boolean): Promise<void> {
if (this.queryForm.valid) {
try {
this._modalReference.isLoaderVisible = true;
this.model.layout.query = {
q: [],
s: {}
}
this.model.layout.query = this.model.query;
let saved = null;
if (isSavedForAllUsers) {
saved = await this._tableLayoutService.addOrUpdateDefault(this.model.layout);
}
else {
saved = await this._tableLayoutService.addorUpdate(this.model.layout);
}
if (saved) {
this.submitData()
this._snackbarService.success('Saved successfully')
}
else {
this._snackbarService.error('Failed to save')
}
finally {
this._modalReference.isLoaderVisible = false;
}
}
}
Should I somehow call some code in ngOnInit function?

Foreach, With only one DisplayAlert Popup?

Hi guy's i'm trying to figure out a way to display a DisplayAlert Popup when Someone entered the Wrong details into the Login Process.
Issue is, The login's a little "Weird" I'm not comparing against a Database i'm comparing against a List of Customers I get from a APi So I have to loop threw to then find if the detail's are correct.
I have a login Phase 1() which Checks against the Wordpress API but I want to have this be able to notify on Phase 1 and 2, Phase 1 is a Username = Username Password = Password Where phase 2 is just a Username = Username , I know it's not secure The Login is more of a Formality then anything.

}

Any Advice?

you can replace the foreach with a LINQ query
// find the first match
var found = list.Where(user => user.username == Usernamelabel.Text).FirstOrDefault();
if (found != null)
{
// set preferences and navigation
}
else
{
// DisplayAlert
}

c# outlook addin userproperty of first item in collection not found

Outlook 2016
.Net Framework 4.5
i encounter a really strange behaviour:
when i iterate through the items collection of a contact folder in some very special undefined cases (which i do not really understand) some userproperties of the first item of the collection fail to load. However the UserProperties are definitly set.
The approach is following:
I open the contact folder (to which the items will be moved) in outlook.
then i execute the "test"
the execution of the test can be suammrized as following:
click button ->
start thread
iterate through the items (on first iteration no items are present).
add new items{
create item
set userproperty PRE before item is initially saved
save item
move item to desired folder
set userproperty POST after item is moved
save item
}
end thread
click button ->
start thread
iterate through the items (here the userproperty POST sometimes fails to load on the first item of the collection, however when i investigate it, it IS there. It only fails for the first item and succeeds for every other following item).
...END
it seems to me that outlook somehow fails to update the userproperty definitions timely. But note that the first BackgroundWorker thread is already finished when iterating through the items with the second backgroundworker thread.
The problem could be related to the fact that iam viewing the folder in the explorer while the items are added and iterated.
This bug is hard to reproduce and does only occur rarely.
however i'm really missing insight into the inner workings of outlook so i can only speculate.
Idea for workarounds:
I could add an item with all userproperties before moving it. the problem here is that i need to add new userproperties, after the item is initially saved and moved to the folder, in some scenarios.
in few cases the userproperty key is dynamically created (with a pattern) so it wouldn't be optimal to predefine all userproperties.
It's very important that the userProperties are reliably loaded because some important features are based upon them.
Does anybody has a clue how the problem is caused and how to solve it? because this behaviour is driving me crazy.

Outlook Object Model cannot be used on a secondary thread within a COM addin. Outlook 2016 will raise an exception as soon as it detects an OOM object being accessed on a secondary thread.

Input string was not in a correct format in c#.Net for textbox for some of the table names

I have a text box to get the SQL statement from the users. So, the users can type the sql into the textbox and get the results.
private int hasData
{
get
{
try
{
string query = SqlStatement_tbx.Text;
int _hasData = GenericDataAccess.ExecuteScalar(query);
return _hasData;
}
catch (Exception ex)
{
Errorhandling.LogError(ex);
return -1;
}
}
}
In the above method, sometimes it works for some of the tables and sometimes not. I could not figure it out where am doing wrong.
If i do Select * from dba.condition it works.
If i do Select * from dba.project it reports Input String was not in a correct format.
Thanks
Update:
These are the codes in my code behind file
private int hasData
{
get
{
try
{
string query = SqlStatement_tbx.Text;
int _hasData = GenericDataAccess.ExecuteScalar(query);
return _hasData;
}
catch (Exception ex)

Errorhandling.LogError(ex);
return -1;
}
}
}
private string sqlStatement

EmptyData_pnl.Visible = false;
if (hasData > 0)
{

}

}
else

GenericMethods.showPopup(AlertType.Information, "Please check your sql statement!");
}
}
}
protected void BindGridView1()
{
try
{
GridView1.selectStatement = sqlStatement;
GridView1.PagerStyle.HorizontalAlign = HorizontalAlign.Left;

}
catch (Exception ex)

ExecuteScalar
private static Object ExecuteScalar_returnObject_internal(string query, Object[] args)
{
using (SAConnection Conn = new SAConnection(GenerateConnectionString()))
{
SACommand Cmd = new SACommand(query, Conn);
foreach (Object o in args)
{
SAParameter p = Cmd.CreateParameter();
p.Value = o;
Cmd.Parameters.Add(p);
}
Conn.Open();
Object r = Cmd.ExecuteScalar();
Conn.Close();
Cmd.Dispose();
//SAConnection.ClearAllPools();
return r;
}
}
public static int ExecuteScalar(string query, params Object[] args)
{
return Convert.ToInt32(ExecuteScalar_returnObject_internal(query, args));
}

The error you are getting is being produced by the Convert.ToInt32 method in your GenericDataAccess.ExecuteScalar function. This means that the string (or whatever type it is) returned from ExecuteScalar_returnObject_internal is not a valid value that can be converted to an int.
Without seeing more of your code I cannot say for sure why it isn't returning the expected value, however I suggest you step through it with the debugger and evaluate the value being returned by ExecuteScalar_returnObject_internal. It should be fairly obvious why it cannot be converted to an int.
Update
Looking at more of your code we can see that the object being parsed is the result of Cmd.ExecuteScalar (i.e. SACommand.ExecuteScalar). Again, that's not part of the .Net framework but for the sake of speeding things up let's assume it uses SqlCommand.ExecuteScalar on the insides.
We can see that SqlCommand.ExecuteScalar has the following return value:
The first column of the first row in the result set, or a null
reference (Nothing in Visual Basic) if the result set is empty.
Returns a maximum of 2033 characters.
With that in mind, I would say that the first column of the first row when executing Select * from dba.project is either null (perhaps there are no results at all), or the value is not something that can be converted to an Int.
I recommend you debug your query to see what is the first row/column value, or add some error checking and do something else (such as display a message to say "no results found" or "Unexpected return type" or whatever you like)

Sharepoint Sequential Workflow not adding Task into Tasklist
