Hi there!

I am currently having a issues using QtitanDataGrid7.1.0, I'll remove a row from grid,like this.
      GridTableView* view = m_grid->view<Qtitan::GridTableView>();
      GridRow row = view->getRow(0);
      view->removeRow(row);
But the grid always show "Data Error. Can't remove row".
I try using these methords
   bool removeRow(const GridRow& row);
    bool removeRows(const GridRow& row, int count);
    bool removeRowByIndex(int rowIndex);
    bool removeRowsByIndex(int rowIndex, int count);

     view->model()->removeRow(row);
These all didn't work.
How can I remove a row freely.

Thanks a lot in advance,
BR,

Yimin

This error message occurs when the model does not support deletion. It is in the read-only state. What model are you using? Also, you can delete the row directly in the model and the grid will update automatically.
