TMSFNCDataGrid persist column position

FNC TMS FNC UI Pack
1

I try to persist changed column positions. We use our own ui to move columns and save it in a file similar to this:

{
  "Column1": 0,
  "Column2": 2,
  "Column3": 1
}

No i have two problems, i'm not sure if i'm using it wrong or there's some bug in the grid.

First: When Changing Column Positions i use MoveColumn. This moves the column in the grid but doesn't update the indices:

	auto p1 = this->DataGrid->Columns->Items[1];
	auto p2 = this->DataGrid->Columns->Items[5];

	this->DataGrid->MoveColumn(1, 5);
	ShowMessage(p1->Index);

The ShowMessage prints "1". In my Opinion MoveColumn should print 5 as it is the new Index of the column.

Changing the Index of two columns on the other hand has no effect on the Grids visual presentation:

	auto p1 = this->DataGrid->Columns->Items[1];
	auto p2 = this->DataGrid->Columns->Items[5];

	int a = p1->Index;
	int b = p2->Index;

	p1->Index = b;
	p2->Index = a;

With this code i expected that the two columns are changed in grid visual presentation but it's not.

So i don't really know how to load my column positions?!

In the grid, MoveColumn, or SwapColumn will transfer data between columns. It does not effectively change indexes. This means that the index remains the same. To know the index after swapping, you can use

this->DataGrid->Root->RealToDisplayColumn(1);

Changing the index will indeed not change the order in the grid for the same reason. Please use MoveColumn or SwapColumn to address this. We'll add this on our todolist to call MoveColumn or SwapColumn internally when changing indexes at column level.
