    Hi. i am quite new to telerik controls. i have a hierarchical datagrid where i am using a dataset to bind the grid that has two data table. Orders and OrderProducts.  Order is parent grid and OrderProduct is child grid. Filter work well on child grid but it works on only child rows.

    I want to show only those orders in the grid where OrderProducts.productstatus = 'something'. Currently i am using code as below.

                dgOrders.DataSource = ds.Tables[0];
                GridViewTemplate template = new GridViewTemplate();
                template.DataSource = ds.Tables[1];
                GridViewRelation relation = new GridViewRelation(dgOrders.MasterTemplate);
                relation.ChildTemplate = template;
                relation.RelationName = "OrderProducts";

    Any help is really appriciated.

    Hello Ujjawal,

    Thank you for writing.

    In RadGridView the filtering works per template and to achieve the desired functionality you should add a filter descriptor to the child template. For example:
    GridViewTemplate template = new GridViewTemplate();
    template.DataSource = nwindDataSet.Products;
    template.EnableFiltering = true;
    FilterDescriptor filter = new FilterDescriptor();
    filter.PropertyName = "CategoryID";
    filter.Operator = FilterOperator.IsEqualTo;
    filter.Value = 2;

    I hope this helps. Should you have any other questions do not hesitate to ask.
