GridColumn Type ColumnType.CheckBox What event should I define when all are selected or all are not selected
I want to make the chart data invisible when deselecting all.
public async Task Grid_master_RowSelect(RowSelectEventArgs<Examine_chart_de> args)
{
args.Data.examine_chk = true;
var dataSource = Examine_chart_row;
int i = 0;
foreach (var chartdata in dataSource)
{
if (args.Data.gtw_id == chartdata.gtw_id)
{
//chartdata.visible_val = args.Data.examine_chk;
SeriesCollection[i].visible_val = true;
}
i++;
}
StateHasChanged();
}
public async Task Grid_master_RowDeselect(RowDeselectEventArgs<Examine_chart_de> args)
{
args.Data.examine_chk = false;
var dataSource = Examine_chart_row;
int i = 0;
foreach (var chartdata in dataSource)
{
if (args.Data.gtw_id == chartdata.gtw_id)
{
//chartdata.visible_val = args.Data.examine_chk;
SeriesCollection[i].visible_val = false;
}
i++;
}
StateHasChanged();
}
- I don't know how to define and apply events when deselecting all and deselecting all.
