get_masterTableViewHeader()

This property returns the MasterTableView header instance for the respective grid client object.

get_masterTableViewHeader()

Example:

function getMasterTableViewHeader() {
    var grid = $find("<%=RadGrid1.ClientID %>");
    var masterTableViewHeader = grid.get_masterTableViewHeader();
}

Please, keep in mind that this property would only return a non-null value when scrolling with static headers is enabled:

<clientsettings>
        <Scrolling AllowScroll="true" UseStaticHeaders="true" />
</clientsettings>

In all other cases, this property will return a null value.
