iOS render when large data

[Huy Tran]

Hi

Current, I am using this example: https://support.syncfusion.com/kb/article/6518/how-to-improve-performance-when-doing-bulk-changes-in-sfdatagrid

I handle QueryRowHeight event, caculate height of row, set "e.Handled = true", and i have a render issue when i scroll to bottom grid like bellow image. When load large data.

Touch to screen and move up or down, this issue disappear.

I have tried newest version but can not fix my issue,

Device tested: Iphone X(iOS 16.5.1)

Please can help me?

This is my event:

private void DataGrid_QueryRowHeight(object sender, QueryRowHeightEventArgs e)

        {

            if (e.Height != dataGrid.RowHeight && e.Height != 0)

                return;

            e.Height = dataGrid.GetRowHeight(e.RowIndex) - 19;

            e.Handled = true;
