Popup Form/Panel On Cell Hover/Click

Is there any way to implement a panel or a form that displays when a user hovers over or clicks on a cell in the grid?

I've looked at the code on how the combobox does its dropdown, using the PopupForm class, but i haven't had any luck.

What about a button that shows a drop down? basically a combobox without the textbox aspect. I want to be able to put the contents of a usercontrol on to the popped-up panel.

How do I obtain the value in a cell for a selected Row?

I want the cell value from RadVirtualGrid as the user selects a row.

I don't have multi-select enabled.... And, I have row select.... So, there should be only one row selected at a time.

I'd like the text or number that appears in one of the columns. For example, the text value of the first column (0)

How is this obtained?

[Solved] How to show or hide primitive type and compound type at runtime?

I have a business object ,

public class Person

{

public string Name {get;set;}

public bool Show {get;set;}

public class Company {get;set;}

}

public class Company

{

public string Name {get;set;}

public string Address {get;set;}

}

I expect that Company will hide when the Show is false, and vise versa.

Show or hide some property at runtime.

I have a customize object just like this.

01.public class Person

02. {

03. [CategoryAttribute("Personal Info.")]

04. public Name Name { get; set; }

05. [CategoryAttribute("Personal Info.")]

06. public int Age { get; set; }

07. [CategoryAttribute("Profession Info.")]

08. public Profession Profession { get; set; }

09. }

10.

11. public class Profession

12. {

13. private Title title_;

14.

15. public string Company { get; set; }

16. public string Address { get; set; }

17. public Title Title

18. {

19. get { return title_; }

20. set

21. {

22. title_ = value;

23. if (title_ == Title.Manager)

24. {

25.// hide property subordinates

26. }

27. else if (title_ == Title.Developer)

28. {

29.// show property subordinates

30. }

31. }

32. }

33.

34. public List<Person> Subordinate { get; set; }

35. }

Is there a way to show or hide Subordinate according to the property Title? When I selected the Title with Manager, the subordinate will appear. When I selected the Title with Developer, the subordinate will hide.

RadGridview Virtual Mode filtering/grouping/sorting

Hi,

I need to filter/group/sort through more than 100,000 records.
Loading all records to datatable takes long time and keeping preloaded data in datatable increases memory consumption.
I'd like to implement virtual mode in GridView, so I can retrieve first X rows of data to datatable based on columns filters.
Can someone give me an example of using Virtual Mode with filtering/grouping/sorting.
In all examples that I found so far, filtering option is set to false.

Thank you,
Tamara
