Multiple selection only on specific rows

Question

Hello,is it possible to enable multiple selection only on specific rows according to some flag? Let's say that this flag could be number 1 or something similar. This flag is also in grid grouping control displayed in column and loaded from table from database?

Hi Josip, 

Thanks for using Syncfusion product. 

In order to avoid the selection based on the specific column value, The SelectedRecordsChanging event can be used to handle the selection and Record.GetValue method can be used to get the specific column value from the record. Please refer to the below code example, 

Code example 





this.gridGroupingControl1.Table.SelectedRecordsChanging += Table_SelectedRecordsChanging; 
 
void Table_SelectedRecordsChanging(object sender, Syncfusion.Grouping.SelectedRecordsChangedEventArgs e) 
{ 
    if (e.Action == Syncfusion.Grouping.SelectedRecordsChangedType.Added) 
    { 
        String value = e.SelectedRecord.Record.GetValue("Select").ToString(); 
        if (!value.Equals("1")) 
            e.Cancel = true; 
    } 
}
