hi, I have enable filtering on selected column and that column has Hierarchical Data. in filtering its showing top level data but not showing child level data. please let me know what are the issues will be so that i can resolve. or anything you can suggest me to achieve this. i have used this.theGrid.FilteringSettings.AllowFiltering = FilterUIType.FilterMenu; setting. but if i used this.theGrid.FilteringSettings.AllowFiltering = FilterUIType.FilterRowTop setting then it will be showing filtering to all level in my particular column and child level in all other column. Thanks Kanhaiya Kumar
