Grouping in child template

[Jarek Rutowicz]

Welcome,
I have a problem with grouping colums in child templates.

this.radGridViewMachines.EnableGrouping = true;
this.radGridViewMachines.AllowDrop = true;
this.radGridViewMachines.MasterGridViewTemplate.AllowDragToGroup = true;
this.radGridViewMachines.MasterGridViewTemplate.EnableGrouping = true;

templateWarehouse.EnableGrouping = true;
templateWarehouse.AllowDragToGroup = true;

What else I have to do to turn on grouping in templateWahouse?
Jarek.

Hi Jarek Rutowicz,

You should only set the EnableGrouping property to true. This should be enough. You can add grouping by code. Here is a sample:

templateWarehouse.GroupByExpressions.Add("Value GroupBy Value");

Please describe the issue in more details. This will help me to find a proper solution for you. I am looking forward to your reply.

Best wishes,

Well, I can't make it work.
I've made a simple app to describe the problem:

DataClasses1DataContext db = new DataClasses1DataContext();
            this.bindingSource1.DataSource = from MachineGroupsView m in db.MachineGroupsViews select m;
            this.bindingSource2.DataSource = from WarehouseDetailsView w in db.WarehouseDetailsViews select w;

            this.radGridView1.DataSource = this.radGridView1.DataSource = this.bindingSource1;

            GridViewTemplate templateChild = new GridViewTemplate();
            templateChild.DataSource = this.bindingSource2;
            templateChild.EnableGrouping = true;
            this.radGridView1.MasterGridViewTemplate.ChildGridViewTemplates.Add(templateChild);

            GridViewRelation relation = new GridViewRelation();
            relation.ChildTemplate = templateChild;
            relation.ParentTemplate = this.radGridView1.MasterGridViewTemplate;
            relation.ChildColumnNames.Add("idWarehouse");
            relation.ParentColumnNames.Add("idWarehouse");

            this.radGridView1.Relations.Add(relation);
            this.radGridView1.EnableGrouping = true;

Hierarchy works ok, but grouping works olny in MasterGridViewTemplate. I need it to work in templateChild.
Thank you for your replies.

Hi Jarek Rutowicz,

This code seems to be OK. However, I don't see code that makes the grouping. You should do this by adding group expression or by using the UI. Please describe how do you make the grouping. It will help if you send me your application. This way I will be able to investigate this case further and find a proper solution.

I am looking forward to your reply.

OK:)
I've thought that child template would have his own row where I should drag columns. Now I understand that I shoud drog columns to main GridView.

Thank you for Replies, Jarek.
