RowSelectionModel sm = this.grdPrice.SelectionModel.Primary as RowSelectionModel;
            //clear select row
            sm.SelectedRows.Clear();
            sm.UpdateSelection();
            //get select row index
            sm.SelectedRows.Add(new SelectedRow(0));
            sm.SelectedRows.Add(new SelectedRow(12));
            sm.UpdateSelection();

gridpanel pagesize =10
total row count =20
but only row 0 which in page 1 was selected . the row 12 which in page 2 can't change state to be seleted

Hi,

Welcome to Ext.NET!

You should set up IDProperty for Store Reader to get it working through rest (not current) pages.

What data do you bind to the Store?

[dew3083142]

data table

[Daniil]

Is there ID column?

[dew3083142]

no ,there isn't a column names 'ID' in the datatable

[dew3083142]

Is there ID column?

Do you means the IDproperty should be one column of the datatable?
I also try that ,but all the same
