Hi everyone!
We are doing project with grid hierarchy and tabbed views.
But there are 2 problems:
1. If there is no records in both fields of DataSource, both tabs are not displayed. If only first field has no records, second tab also is not displayed.
2. PageViewMode change does not affect the type of grouping tabs. 

I made little project to repeat second problem and partly first.

Hi Nikita,

Thank you for contacting us.

I was not able to reproduce such behavior in a sample application. Both tabs were showing no matter if there were entries or not. You can find my sample application below.

Maybe you are somehow hiding the tabs? Please try to change my sample project and get back to me. Alternatively provide me with another sample project in which the problem is reproducible.

Looking forward to your report.

Regards,
George

George, hi! Thanks for response! Sorry for the long silence. 
Yes, in your sample application everything is working, but in my project is not all so good. 
We use abstraction in our project, so I removed the superfluous in my test project. Please look again, and note the lines: 
rgvMain.TableElement.PageViewMode = PageViewMode.Stack;
rgvMain.MasterTemplate.Templates [0]. ExpandAll ();

They also do not work as they should. I think the problem in a hierarchy.

Hooray, I found a solution. In the GridView we had a code: 

private bool IsExpandable(GridViewRowInfo rowInfo)
{
    return rowInfo.ChildRows != null && rowInfo.ChildRows.Count > 0;
}
 
private void rgvMain_ChildViewExpanding(object sender, ChildViewExpandingEventArgs e)
{
    e.Cancel = !IsExpandable(e.ParentRow);
}
 
private void rgvMain_ViewCellFormatting_1(object sender, CellFormattingEventArgs e)
{
    var cell = e.CellElement as GridGroupExpanderCellElement;
    if (cell != null && e.CellElement.RowElement is GridDataRowElement)
    {
        cell.Expander.Visibility = !IsExpandable(cell.RowInfo)
            ? ElementVisibility.Hidden
            : ElementVisibility.Visible;
    }
}


The problem is that if the group 2 template, and the first blank and the other not, rowInfo.ChildRows.Count was zero.

But problem with 
rgvMain.TableElement.PageViewMode = PageViewMode.Stack;
rgvMain.MasterTemplate.Templates [0]. ExpandAll ();
is actual.

Hello Nikita,

Thank you for your reply.

I am glad that you resolved one of your issues.

As to the matter with expanding the rows, you need to manually expand each row since in this hierarchy they are not being kept in the templates. This means that every template different from the master has no rows and calling expand will not have effect. Instead, here is the approach you can use:
void Form1_Click(object sender, EventArgs e)
{
    foreach (var row in this.grid.MasterTemplate.ChildRows)
    {
        this.ExpandOrCollapseRecursively(row.ChildRows, true);
    }
}
 
private void ExpandOrCollapseRecursively(GridViewChildRowCollection childRows, bool expand)
{
    foreach (GridViewRowInfo row in childRows)
    {
        GridViewHierarchyRowInfo hierarchyRow = row as GridViewHierarchyRowInfo;
 
        if ((row is GridViewGroupRowInfo || (hierarchyRow != null && hierarchyRow.HasChildRows())) && row.IsVisible)
        {
            row.IsExpanded = expand;
            this.ExpandOrCollapseRecursively(row.ChildRows, expand);
        }
    }
}

This should result in the desired behavior.

Let me know if you have further questions.

Regards,
George
