Multiselect not working

[Bhavin]

I have IList<Vehicle_Data> where
Vehicle_Data has property:      keyvehicletype,owned,VEHICLE_TYPES
where VEHICLE_TYPES has property:   keyvehicletype,DESCRIPTION,POWER_UNIT,TOTAL

there is mapping between vehicle_data,vehicle_types.

Grid doesn't allow me to multiselect rows.please reply ASAP

Hi bhavin patel,

I managed to compile a project that resembles the original one (although some information like the DriverVehicle_Data class was missing) and it seems that the multiple selection is working. Keep in my that if you click on controls that handle mouse and keyboard events (like the MaskedTextBox) their hosting row will not be selected.

May I ask you how are you trying to select multiple items? With this version of RadGridView multiple items can be selected by holding down the CTRL or the SHIFT keys.

I have also attached the sample project that I used.

Kind regards,
Milan
