thanks much!
i suspect still using system.windows.controls.datagridrow type datagridex's rows. use instances of own datagridrowex type, must override getcontainerforitemoverride() method in datagridex class:
public class datagridrowex : datagridrow { // can add custom dependency property here } public class datagridex : datagrid { //... protected override dependencyobject getcontainerforitemoverride() { return new datagridrowex(); } }
