When I type in '10,00' in a gridcell, this becomes 1000. This can be confusing for European users. Is it possible to disallow comma's?

Drag N Drop B/w RadGridView N Desktop..

Hi,

I have a WPF control which has RADGridView in it. I included that control inside a Windows Form using element host. But when I started dragging GridView row outside the element host it doesn't let me do that.

Another problem I wanted to drop a row from RagGridView to Desktop. How can I implement that. It would be nice if you respond promptly.

Thanks in Advance..

property IsExpandable doesn't work correct

I am using a RadTreeListView and MVVM pattern. When I expand new item in my tree some items lost their expanders.
private void RadTreeListView_RowLoaded(object sender, RowLoadedEventArgs e)
{
TreeListViewRow row = e.Row as TreeListViewRow;

if (row != null)
{
row.IsExpandable = !((TreeNodeViewModel)row.DataContext).IsEmpty;
}
}

TreeNodeViewModel - it's an item of tree.

Filter Checkbox Column Type Not Displaying Filter

I have been reading through the changes made to the programmatic filtering and have encountered an issue with regards to a checkbox column type within a RadGridView.

I would like to be able to filter the records that are checked but also have that show up in the filter UI. At this time, I have followed the instructions on how to set the filter, the filter icon highlights and the data is filtered but the appropriate checkbox adjacent to the "False" value in the filter is not checked.

Here is a snippet of the code that resides within the GridLoaded event of my ViewModel.

gridView.FilterDescriptors.SuspendNotifications();
  
GridViewColumn employeeRelatedColumn = gridView.Columns["EmployeeRelatedFlag"];
IColumnFilterDescriptor employeeRelatedFilter = employeeRelatedColumn.ColumnFilterDescriptor;
employeeRelatedFilter.FieldFilter.Filter1.Value = "False";
employeeRelatedFilter.FieldFilter.Filter1.Operator = FilterOperator.IsEqualTo;
  
gridView.FilterDescriptors.ResumeNotifications();

Please advise.

RadDiagramConnection Bezier curve serialization?

I have a number of RadDiagramConnections (as Beziers) in a RadDiagram and need to serialize the individual connection's geometry (the beizer curve).

Basically when the user modifies the look of the bezier I need to store that so next time my model is loaded it will look exactly the same.

I don’t want to use the Diagram’s serialize as the diagram is only a representation of an MVC model.

I also build my own connections from the model but I need to somehow store/restore the bezier curve for each connection.

Help greatly appreciated.

Just a quick update: The user can control the look of the curve by two blue circular elements. They drag either in any direction and the curve changes. All I really need is a way to get/set these "blue ui elements" and the curve will follow.

RadGridView moves extremely slow

I have just implemented the RadGridView, which was an upgrade from the standard .net DataGrid. I have about 100 items in the grid, with about 12 columns and something as simple as a scroll moves very slow. Scrolling is very jerky, and not smooth. I also noticed that if I add sorting and grouping, there are random delays as new items are added to the grid. These delays can be as long as a few seconds even though I have no more than 100 items in my grid. I have profiled the app, and it says the hottest function call is
Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureOverride
This can be make or break for us as we need a low latency high performance data grid.

Nullable Int

Hello,

I have an object with a nullable int property that I am binding to the PropertyGrid. If the int property contains a value and I clear it out, it looks like the grid has validation that requires the int to have a value even though it is nullable. Is it possible to allow the int property to be null?

Thanks,
Blake
