how to make a grid with the local space Unity?

I am gridding around an object but I need the grid to align in the local space of the pivot object
the code that i have
private void createColum()
{
for (int i =0; i<gridGame.Count;i++)
{
if(gridGame[i] == gridGame[0])
{
gridGame[i].localPosition = gridGame[0].localPosition;
}
if(gridGame[i]!= gridGame[0])
{
gridGame[i].localPosition = new Vector3(gridGame[i-1].localPosition.x + distX,gridGame[0].localPosition.y, gridGame[0].localPosition.z);
}
if(i +1 > limiteFila)
{
if(i%limiteFila==0)
{
gridGame[i].localPosition = new Vector3(gridGame[0].position.x, gridGame[0].position.y , gridGame[i-Mathf.RoundToInt(limiteFila)].position.z + distY);
}else
{
gridGame[i].position = new Vector3(gridGame[i-1].position.x + distX, gridGame[0].position.y , gridGame[i-1].position.z);
}
}
gridGame[i].rotation = gridGame[0].rotation;
}
}
with this the grid of objects is formed but only in taking the world space
picture of how you are at this moment

I'm not sure if this will help, but you can turn the grid into a child object and leave the worldPositionStays as false, to do so use the SetParent(Transform parent, bool worldPositionStays). For example as a reference for your script.
private void createColum()
{
for (int i =0; i<gridGame.Count;i++)
{
if(gridGame[i] == gridGame[0])
{
gridGame[i].localPosition = gridGame[0].localPosition;
gridGame[i].transform.SetParent(this.transform, false);
}
if(gridGame[i]!= gridGame[0])
{
gridGame[i].localPosition = new Vector3(gridGame[i-1].localPosition.x + distX,gridGame[0].localPosition.y, gridGame[0].localPosition.z);
}
if(i +1 > limiteFila)
{
if(i%limiteFila==0)
{
gridGame[i].localPosition = new Vector3(gridGame[0].position.x, gridGame[0].position.y , gridGame[i-Mathf.RoundToInt(limiteFila)].position.z + distY);
}else
{
gridGame[i].position = new Vector3(gridGame[i-1].position.x + distX, gridGame[0].position.y , gridGame[i-1].position.z);
}
}
gridGame[i].rotation = gridGame[0].rotation;
}
}

Error messege "The source contains no DataRows" when i sent a data table object to a pagenation Class method

I have a User Control with a DataGrid.Every thing was fine since the DataGride Pagenation Function within the User Control Class.I Desided to move the pagenation functions into a class instead.This is my Code

Pagenation pagenation = new Pagenation(Partsdatagrid, cbNumberOfRecords, PageInformation, PartsDataTable, btnPrev, btnFirst, btnNext, btnLast);
//Pagenation.RefreshDataGrid(PartsDataTable);}
The problem is that i still getting this error message!
The source contains no DataRows
and the error points to the refreshDataGrid method in this line
DatagridObject.ItemsSource = dt.AsEnumerable().Take(numberOfRecPerPage).CopyToDataTable().DefaultView;
Note that the messege box in the function refreshDataGrid shows that i have 50 rows.

Solved it,The thing that caused the error was the function Take() since it takes the number from the combobox that let you choose how many rows to display.I put Fixed number and It Worked.
DatagridObject.ItemsSource = dt.AsEnumerable().Take(15).CopyToDataTable().DefaultView;

Programming issue with no row at position in that table

I am new in coding and I am having the following issue. When I run the select if there are no rows I receive the following error
but in that case, i want to make an insert
how can I do this? This is my entire code:
private DataRow verifica_pontajul()
{
string query = String.Format("select PR_ID,WORKER_Name,PR_Come,PR_Go, CURRENT_TIMESTAMP from `ppresence` {0}",
(Functii.marca == "admin" ? "" :
String.Format("WHERE PR_WorkerPTR='{0}' ORDER BY PR_ID DESC LIMIT 1 ", this.marca)
));
return conn.dt(query,0).Rows[0];
}
public class liniepontaj
{
public long idlinie = 0;
private string angajat = "";
public DateTime DataIntrare = new DateTime();
private DateTime DataIesire = new DateTime();
public DateTime DataReferinta = new DateTime();
private bool isIntrare = false;
public bool facintrare = false;
public bool faciesire = false;
public liniepontaj() { }
public liniepontaj(DataRow rand)
{
this.idlinie = long.Parse(rand.ItemArray[0].ToString());
this.angajat = rand.ItemArray[1].ToString();
this.DataIntrare = (DateTime)rand.ItemArray[2];
try {
this.DataIesire = (DateTime)rand.ItemArray[3];
}
catch (Exception) { this.DataIesire = new DateTime(1, 1, 1, 0, 0, 0); }
this.DataReferinta = (DateTime)rand.ItemArray[4];
if (this.DataIesire == null || this.DataIesire != new DateTime(1, 1, 1, 0, 0, 0)) { isIntrare = true; } else { isIntrare = false; }
TimeSpan t1 = DataReferinta - DataIntrare;
TimeSpan t2 = DataReferinta - DataIesire;
if ((t1.TotalMinutes < 15 && !this.isIntrare))
{
faciesire = false;
facintrare = false;
}
else if (t2.TotalMinutes < 15 && this.isIntrare)
{
faciesire = false;
facintrare = false;
}
else
{
facintrare = isIntrare;
faciesire = !isIntrare;
}
}
}
Where should i modify? To have the properly insert functional?

Basically, you just need to validate if there is any data inside Rows.
var dt = conn.dt(query, 0);
if (dt.Rows.Count == 0) return null;
else return dt.Rows[0];

Check for rowcount and if greater than or equal to 1 and then proceed else insert

Program stops working after minimizing any window in Windows

The program uses two threads: one for collecting the data from USB, and the other writes/displays the data. It seems to work as expected, however, as soon as I minimize/restore any windows on the PC, or press any buttons on the Form, it stops working properly (it stops receiving data). I use link list to keep the data streaming in order. I suspect that maybe the link is lost somewhere because of improper variable declaration. Is there an obvious mistake in my code that could be causing this?

How to get selected value or index of a dropdownlist upon entering a page?

I have a product ordering page with various product option dropdownlists which are inside a repeater. The "Add To Cart" button is "inactive" until all the options have a selection. Technically, the "Add To Cart" button has two images: a grey one which is used when the user has not selected choices for all options available to a product and an orange one which is used when the user has made a selection from each dropdownlist field.These images are set by the ShowAddToBasket and HideAddToBasket functions.
The dropdownlist fields are connected in that a selection from the first field will determine a selection for the second and sometimes third field. If the second field is NOT pre-set by the first field, then the second field will determine the value for the third field. The first dropdownlist field is never disabled, but the other two can be based on what options have been selected.
There are a few products that have all 3 of their dropdownlists pre-set to certain choices upon entering their page. This means they are all disabled and cannot be changed by the user. Regardless of whether the user enters in a quantity or not, the "Add To Cart" button NEVER activates. I cannot for the life of me figure out how to change it so that, in these rare circumstances, the "Add to Cart" button is automatically set to active once a quantity has been entered. The dropdownlists still have options selected in these pages--it's just that they are fixed and cannot be changed by the user.
Is there anyway I can get the selected value or selected index of these dropdownlist fields upon entering a product page? I want to be able to check to see if they are truly "empty" or if they do have selections made so I can set the "Add to Cart" button accordingly.
Any help would be great because I'm really stuck on this one! :(
