Is there a way to sort a hierarchy on child grid columns?

I have a three-level hierarchical grid, in which I'd like each of the sub/child grids to be sorted based on a column.

I'm having no problem getting the top-level grid sorted since there's an OrderBy clause in the query that populates the CollectionViewSource that the grid is bound to.

Is there a property that can be set on the sub-grids to cause them to, by default, sort on a particular column?

Example:

Customers (sorted on last name)
Orders (sorted by date)
Order Line Items (sorted by quantity)

Thanks.

RadGridView Grouping

Hi,

I have User Control containing RadGridView that we are using in WPF module to be used in a "WPF application" as well as in "Windows Application" (using Element Host).

When we use it in Windows App and we group the Grid on Multiple Columns it works fine and it lets us drag the "columns to group" on desired location in the "group header" and also we can reorder the "grouped by" columns as desired.

However when using it in WPF application we are not able to drag the "columns to group" on desired location in the "group header" and also we are not to reorder the "grouped by" columns as desired.

We are doing nothing extra when hosting the control in Windows Form, the exact same control is being used in both the applications.

And help would be really appriciated

LabelColumnWidth = GridLength.Auto

Hello,

When I set LabelColumnWidth to GridLength.Auto, each row's label is sized minimally for that row, resulting in an uneven column. See the attached image. What I'd expect is that the column gets sized to the maximum of all the rows' minimal sizes, and the column line stays whole.

Will this be supported in the future? Is there a recommended workaround?

This project includes Ribbon and a DockManager.
We are planning on relying on the ExpressionDark theme.
So I tried to create a custom theme project and use the xamls deployed with the install as a base line.

Almost all xamls had reference to

xmlns:external="clr-namespace:Telerik.Windows.Controls.External"
which I coudln't resolve.
I tried to make them styles implicit but also it didn't avail.
Can you assist me please,
Ariel

Tooltips are x+1 ahead of plotted values

The tooltips for my line series are always x+1 ahead of the plotted values. Is this because I'm forcing my X-Axis to be zero-based instead of one-based (which I had to do by manually adding data points since the IsZeroBased property had no effect on the X-Axis). Is there a way to correct this behavior? Thanks!

RadGridView calling GetEnumerator() excessively on IPagedCollectionView

Hello,

I have a class which implements your SL IPagedCollectionView interface, and largely based my code on what you've done in the Endless Paging example.

One thing I noticed, is that on any page change, both in your sample code and in my code, GetEnumerator is called more than once on a page change. This is pretty detrimental if I'm making several calls to the db for my data when I only need 1.

Been trying to step through with the debugger and cannot determine what's causing the problem.

In the hierarchical grid below, I have a self-referencial table that has the hieratchical data.

I cannot get the nested grid to display the same row colours as the outhermost nested grid. 

I am trying to use the RowLoaded event to colour the rows, but it does not fire for the innermost 

nested grids. 













void

RadGridView1_RowLoaded(object sender, RowLoadedEventArgs e)

{

GridViewRow viewRow = e.Row as GridViewRow;

DataRow row = e.DataElement as DataRow;

//Employees employee = e.DataElement as Employees;

if (row != null && row["ID"] != null)

{

long ID = (long)row["ID"];

viewRow.IsExpandable = this.HasSubordinates(ID);

if (row["Status"].ToString().Trim() == string.Empty)

{

viewRow.Background = Brushes.Turquoise;

}

else

{

viewRow.Background = Brushes.Red;

}
