Recalculating all index numbers following deleting a row

[Krm974]

I built a form having rows, where there is item numbers for each row such as 1 / 2 / 3 ...

I use following to add a new instance:

form1.Button.Button1::click - (FormCalc, client)
Table1._Row1.addInstance();

I use following to delete the last instance:

form1.Button.Button2::click - (FormCalc, client)
var nCount = Table1.Row1.instanceManager.count ;
//remove instance
Table1.Row1.instanceManager.removeInstance(nCount-1);

Below script is to show row numbers at the first column. 

form1.Table1.Row1.ItemNo::enter - (FormCalc, client)
var rowCount = this.parent.instanceManager.count;

form1.Table1.Row1.ItemNo::calculate - (FormCalc, client)
this.rawValue = this.parent.index + 1;

these above works great; however lately I needed to delete a random instance which is not the last row using:

form1.Table1.Row1.#subform[0].del_button::click - (JavaScript, client)

_Row1.removeInstance(this.parent.parent.index);

Now there is such a bug when I delete another instance which is not the last instance, row numbers do not recalculate.  

so lets say: I have row numbers 1 / 2 / 3 / 4 and delete the 3rd instance; row numbers listed appears   1 / 2 / 4

Is there a way each time an instance is deleted below script to work:

Hi @Krm974 

Can you please try by force re calculate 

// Delete the current row
_Row1.removeInstance(this.parent.parent.index);

// Force re-calculation of the form so row numbers update
xfa.form.recalculate(1);

If you don’t want to recalc the whole form, you can loop through just the table rows and reset numbering:

_Row1.removeInstance(this.parent.parent.index);

for (var i = 0; i < Table1._Row1.count; i++) {
    Table1.Row1[i].ItemNo.rawValue = i + 1;
}

Hope this helpful 🙂

Dear Karishma, thanks for the support. Here follows is the outcome:

Either: 

xfa.form.recalculate(1);

for (var i = 0; i < Table1._Row1.count; i++) {
    Table1.Row1[i].ItemNo.rawValue = i + 1;
}

not worked for me. Most probabaly reason, as, I placed the delete button inside the row; after button is clicked it deleted the row instance and code stops.

Following Code worked in a separate button:

// Force re-calculation of the form so row numbers update
xfa.form.recalculate(1);

Following Code not worked even  in a separate button:

_Row1.removeInstance(this.parent.parent.index);

for (var i = 0; i < Table1._Row1.count; i++) {
    Table1.Row1[i].ItemNo.rawValue = i + 1;
}

So at this point my question is, is there a way to get the code work after the button (Which is including the code) is deleted?

Hi Kautuk, your community seems very weak as for days I can not wait for an action.

I will ask for else where for a professional assistance.
