DataGrid with duplicate items

[rgomezia]

Hi people , i try to work with duplicate items but the grid automatically update the similar items when i edit someone or when add a new item i have a method this give LineId automatically , but the same problem when add other similar items all remain with the lineid of the last one

a have this in code lineId Method and Grind Config.

ordenMantetimiento.VID_MTOMMACollection = new List<VIDMTOMMACollection>(); for (int i = 0; i < currentList.Count; i++) { currentList[i].LineId = i + 1; } ordenMantetimiento.VID_MTOMMACollection = currentList;

<DataGrid @ref="dataGridMateriales" TItem="VIDMTOMMACollection" Data="@ordenMantetimiento.VID_MTOMMACollection.Where(x=> x.U_ItemName != string.Empty)" Sortable="true" Filterable="false" ShowPager="false" Responsive="true" Editable EditMode="DataGridEditMode.Inline" RowSelectable=@((x)=> x.Item.U_Cerrada != "Y") Narrow="true" VirtualizeOptions="@(new() { DataGridHeight = "350px"})" Virtualize>

Plz if someone know how to resolve , that help me a lot. TY

What-s in the currentList? Are you sure all the items are different object references?
We'll need a full-code reproducible, I can't see anything else wrong with just that bit of code.

I was able to solve it, I really don't know why but when passing the context as a parameter to my method and then adding it to my list it didn't take it, I had to manually create the obj and map it like this.

        int nextLineId = 1;
        foreach (var item in ordenMantetimiento.VID_MTOMMACollection)
        {
            item.LineId = nextLineId++;
        }

        var material = new VIDMTOMMACollection
            {
                DocEntry = ordenMantetimiento.DocEntry,
                VisOrder = 1,
                Object = "VID_MTOM",
                U_WhsCode = tallerSeleted.U_WhsCode,
                U_ItemCode = materialSelected.U_ItemCode,
                U_ItemName = materialSelected.U_ItemName,
                LineId = nextLineId++
            };

        ordenMantetimiento.VID_MTOMMACollection.Add(material);`

Is VIDMTOMMACollection a record or struct type?
