Hi,
I've a gallery grid connected to SP list.

When I try to add a new row, my previous row disappeared.

Could you please help me, what the problem is?

OnSelect property on Add button:

ForAll(
 Sequence(NumberInput1.Value),
 Patch(
 TableList,
 Defaults(TableList),
 {
 Column1: "",
 Column2: "",
 Column3: "",
 GUID_Form: DataCardValue5.Text
 }
 )
);
Set(varReset, false);
Set(varReset, true);

Hello, @xvzms You may create a collection for that, like you have created a collection in the app on start, and then you may patch the value in this collection, and this collection will be used as a data source. I hope this will help you. Please accept it as a solution if it's helpful to you. Thanks!

App On start's Collection:
ClearCollect(
colSheetData,
{ID: 1}
);

Screen's on visible property:
If('galTimeSheetNewEntry'.AllItemsCount = 0 , Patch(
colSheetData,
Defaults(colSheetData),
{
ID: If('galTimeSheetNewEntry'.AllItemsCount = 0 , 1, Last(colSheetData).ID + 1)

}
))

+ Add button code:
Patch(
colSheetData,
Defaults(colSheetData),
{
ID: If(
'galTimeSheetNewEntry'.AllItemsCount = 0,
1,
Last(colSheetData).ID + 1
)
}
);

Remove line code:
Remove(//If delete icon was selected
colSheetData,
LookUp(
colSheetData,
ID = galTimeSheetNewEntry.Selected.ID
)
);
