Popup Dismissed unexpexpected

My form having a MultiColumn ComboBox , (version 2016.1.112.40 ) the data bound it it is long, 500+ columns. When i press down arrow next to text area, popup is flashing and dismisses but when i double click it appears.

While debugging i realize drop down closing event is being fired due to some 'bubble event / mouse down. What is happening?, The form has lot of other non Rad controls. But control focus remains intact when this happens.

Please help.

Here is my code for initializing it.

01.var productService = UnityContainer.Resolve<ProductService>();

02. var productCodes = new List<DAL.Model.Product>();

03. var productCodeList = await productService.GetAllProductCode(null);

04.

05. if (productCodeList.Any())

06. {

07. productCodeList = productCodeList.DistinctBy(x => x.ProductCode).ToList();

08. productCodeList = productCodeList.Where(x => x.ProductStatusID != null).OrderBy(x => x.ProductCode).ToList();

09. productCodeList.RemoveAll(x => x.IsDevice == true && x.ProductStatusID == 0);

10. productCodes.AddRange(productCodeList);

11. }

12. var productList = productCodes.Select(x => new CustomComboSourceDto

13. {

14. Id = x.ProductID,

15. Name = x.ProductCode.ToUpper(),

16. Description = x.ProductDescription

17. }).ToList();

18.

19. productList.Insert(0, new CustomComboSourceDto { Id = -1, Name = string.Empty, Description = string.Empty });

20. comboBoxProductCode.DataSource = productList;

21.

22.

FilterDescriptor descriptor = new FilterDescriptor(this.comboBoxProductCode.DisplayMember, FilterOperator.StartsWith, string.Empty);

23. this.comboBoxProductCode.EditorControl.FilterDescriptors.Add(descriptor);

size frequency

Dear Telerik,

I am using pivotGrid and pivotFieldList

I am having some size frequency data where all the sizes fall into different size classes. I want a continuous set of size classes but as no lengths exists for some size classes, I am getting gaps in the size classes.

Please have a look at the attached files. You will see that the size classes are missing between 3 and 8 are more.

Your help in getting a consistant continuous x axis is appreciated.

Thanks,

PanoramaElement DragDropService

Hello,

I have a Panorama with one Group (Group A) that contains a few tiles. I have changed the AllowDrag and AllowDrop for allow of these tiles to false to prevent Users from rearranging "Group A" tiles. At run-time, more groups and tiles are dynamically added based on individual user setting files. I am using the panorama.PanoramaElement.DragDropService.PreviewDragOver event to prevent users from dragging dynamically added tiles to "Group A".

First I get the position of the cursor on the Panorama using panorama.PointToClient(MousePosition). Then I get the left most Group (Group B) that is not "Group A" and set the EventArgs.CanDrop to false if the cursor is left of "Group B's" ControlBoundingRectangle.Left.

However, I found that if you drag a tile by first clicking on the right most edge of the tile and position the cursor just to the right of "Group B's" ControlBoundingRectangle's left edge, most of the tile hovers over the "Group A" but the cursor is within "Group B" and EventArgs.CanDrop is set to true. So when the user release the mouse, it puts the tile in "Group A".

I looked at panorama.PanoramaElement.DragDropService.PreviewDragDrop and the EventArgs.DropLocation.X was 165 when in the panorama.PanoramaElement.DragDropService.PreviewDragOver the panorama.PointToClient(MousePosition).X was 250 (under 250 is when EventArgs.CanDrop is set to false).

How can I determine if a tile is going to be dropped into "Group A" and cancel or prevent it?

IWorkbookFormatProvider and Telerik.Windows.Maths

Hi,

I deleted the Telerik.Windows.Maths dll from my project as I saw on another thread it was no longer required with the 2016 Q1 release. However, deleting it has caused it to stop my IWorkbookFormatProvider code from working (bringing up the 'Could not load file or assembly Telerik.Windows.Maths ...' etc. error), and obviously now, I can't re-download it. What should I do now?

Thanks for your help.

RadGrid sorting and dataset sorting

I have a radgridview which is bound to a dataset.
When the user sorts the radgrid, the dataset is not sorted equally so it does not give the correct data back for editing.

Is there a solution to that ?

Read-only Columns/Rows/Cells

Is there a way to make specific columns, rows or even certain cells read-only in the grid on the side of the gantt chart. For example, I don't want users to be able to edit the name or dates of a task directly in the grid. Instead I want the user to have to double click on a line in the grid to bring up a window where they can edit those details.
